5 EUROPEAN COIION' PROFICIENCY TET 7 ON PETICIE REIUE IN FRUIT AN VEGETABLE 00 The 7 th European Commission's Proficiency Test was performed in 00 using a grape homogenate. The grapes were grown in the south of pain, in Almeria, and were treated with a post harvest treatment where commercial formulations were applied using a microspray technique. ixteen pesticides were used for the treatments. Participating laboratories were provided with a blank grape homogenate as well as the treated test material. One hundred and twenty eight laboratories agreed to participate in this proficiency test. The median values of the analytical data submitted were used to obtain the assigned (true) concentrations for each of the sixteen residue pesticides present. A fit-for-purpose (FFP) target standard deviation of %, based on the experience of the Advisory Group, was chosen to calculate the target standard deviations (σ) as well as the z-scores of each of the compounds present. For the assessment of the overall laboratory performance the criteria Weight um of z-core (WZ) used in the last proficiency test has been applied. Only laboratories that fulfilled the criteria of detecting at least fourteen of the sixteen pesticides (~90%) with no false positives reported, have been classified as having sufficient scope, and have therefore been placed in Category A. Within this category, the laboratories have been classified as good, satisfactory or unsatisfactory. All the other laboratories have been placed in Category B, and classified as having insufficient scope. For laboratories in Category B, individual z-scores were calculated, but their overall performance has not been assessed, although this year they have been ordered by the number of pesticides reported and the number of acceptable z-scores achieved. Furthermore, classical procedures for summing z-scores (Z and RZ) were employed using the individual z-scores of the participating laboratories. Final Report- European Commission s Proficiency Test 7, 00

6 . INTROUCTION The Council irectives (8//EEC and 90//EEC) provide for the organization and financial support for regular proficiency testing of the laboratories that perform analyses for their official national monitoring programmes. These proficiency tests are performed in order to assure the quality, accuracy and comparability of the residue data sent by EU ember tates to the European Commission and to the other ember tates on an annual basis. The EU Commission's Proficiency Tests - were carried out from 99-00, and were all organized by the wedish National Food Administration. This year, as in 00, the University of Almeria, pain, organized the European Proficiency Test. Participation in this 7 th European Proficiency Test was open to all official national or regional analytical laboratories involved in the determination of pesticide residues in fruit and vegetables in ember tates of the EU and, additionally, laboratories from Iceland, Norway and Romania were included by invitation. A total of one hundred and twenty eight laboratories agreed to participate in the 7 th Proficiency Test. The test material, 00 g of grape homogenate containing pesticide residues, together with 00 g of blank grape homogenate, were shipped to participants on the th, th and th of April, 00. The deadline for submission of results to the organiser was the 0 th of ay 00. The participants were provided with a list of sixty-five pesticides (Annex ), which might be present in the test material and they were asked to determine the levels of all the pesticide residues they detected. Participants were also asked to analyse the blank test material and report residues of any pesticide they found which was included in the list. This blank material was intended for use in performing recovery experiments with the pesticides found in the test material, and if necessary, for the preparation of matrix-matched calibration standards. Final Report- European Commission s Proficiency Test 7, 00

7 . TET ATERIAL. Analytical methods Two analytical methods, described briefly below, as well as other procedures, were used by the Organisers for the homogeneity and stability tests performed at the laboratory of Coexphal (Almeria): GC method []: ethyl acetate extraction in the presence of sodium sulfate, filtration, addition of more sodium sulfate, evaporation, re-dissolution in cyclohexane and determination by /. LC method []: ethyl acetate extraction in the presence of sodium sulfate and addition of sodium hydroxide, filtration, addition of more sodium sulfate, evaporation, re-dissolution in methanol, and determination by LC-/. Acetamiprid, carbaryl, imidacloprid, methomyl and thiabendazole were determined using the LC-/ method. All other pesticides, were analysed using the GC method. For confirmation purposes, / spectra were used.. Preparation of the treated test material Before preparing the test material, the pesticides and suitable residue levels for the study were selected following recommendations made by the Advisory Group, which had been specifically appointed for Proficiency Test 7. The grapes were grown in the south of pain, in Almeria. One hundred and fifty kilograms of grapes were sampled and treated post-harvest with a commercial formulation dissolved in water and applied to the grapes using a microspray. ifferent formulations were applied for each of the pesticides allowing one hour to elapse between applications. A portion was taken and analysed to check the residue levels present in the material. When the grapes contained residue levels close to those recommended by the Advisory Group they were frozen and chopped using liquid nitrogen and a mincer, then mixed in a constantly spinning container especially designed and built by the organiser, until a homogeneous material was obtained. Portions of 00 g, of the well-mixed homogenate, were weighed out into screw-capped polyethylene plastic bottles, sealed, and stored in a freezer at about - 0 C prior to distribution to participants.. Preparation of the blank test material The grapes to be used for the production of the blank test material were organically grown in the same area as the test material, in Almeria, in the south of pain. A homogenate was prepared in the same way as the treated test material described above. ome very low level traces of pesticides were found in the blank: carbendazim, carbaryl, dimethoate, chlorpyriphos-methyl, pyridaben and bifenthrin. Bifenthrin was not included in the Pesticide List provided by the Organizer. All were found at concentrations below 0.0 mg/kg. Final Report- European Commission s Proficiency Test 7, 00

8 . Homogeneity test Ten bottles were randomly chosen from those stored in the freezer and analyses were performed on duplicate portions taken from each bottle. The sequence of analyses was determined using a table of randomly generated numbers. The injection sequence of the 0 extracts analysed by GC and LC was also randomly chosen. The quantification by GC and LC was performed using a -point calibration curve constructed from matrix-matched standards. One standard mixture was used, for both GC and LC. The statistical evaluation was performed according to the International Harmonized Protocol published by IUPAC, IO and AOAC []. The individual residue data from the homogeneity tests are given in the Appendix. The results of the statistical analyses are given in Tables A-B. The acceptance criteria for the test material to be sufficiently homogenous for the proficiency test were that F critical > F for (p = ), and that the between sampling standard deviation s was lower than the analytical a, for all pesticides.

The two occasions were: - ay : coinciding with the first sample shipment, which took place th / th of April ay : shortly after the deadline for reporting results, 0 th ay 00. The individual results are given in Tables A-B. In general, these tests did not show any significant decrease in the levels of the pesticides and demonstrated that the pesticide residues present in the test material remained stable for the duration of the proficiency test.

11 . istribution of test material and protocol to participants One bottle of incurred test sample and one bottle of blank material were shipped to each participant in boxes containing dry ice. The samples were sent on the th, th and th of April 00. Before sample shipment, the laboratories received full instructions (Annex ) for the receipt, storage and analysis of the test materials, although they were encouraged to use their normal sample receipt procedure and methods of analysis. These instructions were uploaded onto the EUPT 7 web page constructed especially for this Proficiency Test. A password was required to enter a restricted zone where the Protocol and the Pesticide List with the inimum Required Performance Level (RPL) established by the Organizer could be found. This information was notified by to all participant laboratories at the same time as they were informed that their application form for participation had been accepted. This ensured that confidentiality was maintained throughout the entire Proficiency Test 7. Final Report- European Commission s Proficiency Test 7, 00 7

12 . TATITICAL ETHO. Background.. Proficiency Tests - For the previous Proficiency Tests -, different methods for the estimation of the assigned values and standard deviations (s) of the analytical data were used. The arithmetic mean values, after elimination of outliers, were used for Proficiency Tests -, while the s were calculated using the Horwitz equation. In Proficiency Test, the median of the results was chosen as the best estimate of the true concentration. Estimates of the standard deviations were compared using four methods. The traditional approach (IO 7-Part ) with outlier elimination robust statistics using both the Qn and wiss methods and a fixed target value (fit-for-purpose) as stipulated by the Advisory Group. The two robust statistical methods, for the estimation of the gave only marginal differences in the results, whilst the other two methods produced results that differed significantly. In Proficiency Test, the same two robust statistical methods were compared and again only marginal differences were found. z-cores were used in all the previous proficiency tests for the assessment of the laboratory performances for individual pesticides. The sums of scores, the RZ (the re-scaled sum of z-scores), Z (the squared sum of z-scores) and RLP (relative laboratory performance) were also calculated as for the last Proficiency Test (PT)... Proficiency Test In this proficiency test, the median was used to obtain the assigned concentration values for each pesticide. This was then used to calculate the z-score. The target standard deviations (σ) were calculated using the FFP (fit-for-purpose) value, which was assigned as %. Furthermore the Qn-method was also used to calculate standard deviations. um of z-cores: the RZ and Z were also used but an additional new criterion was introduced for PT with the agreement of the Advisory Group as well as G anco. This was used as the basis for separating the labs into two categories, A and B. To be classified as Category A, sufficient scope had to have been demonstrated. This scope was that or more results (from the pesticides present in the treated test material) must have been submitted with no false positives. All labs reporting less than results, or having reported a false positive were classified as Category B... Proficiency Test 7 In this proficiency test, the median has also been used, together with a FFP of %. The Weighted um of z-cores (each z-score was multiplied by a weighted function see..) was used to classify laboratories as Category A or Category B depending on the number of pesticide residues reported. 8 Final Report- European Commission s Proficiency Test 7, 00

13 . False positives and negatives.. False positives In principle, reported results that show the presence of pesticides that were included in the pesticide list, and which were (i) not used in the preparation of the test material, (ii) and not detected by the organizer, even following a repeat analysis, were treated as false positives, if they were reported at concentrations at or above the RPL stipulated by the Organizer. Results reported that were lower than 0.0 mg/kg have been ignored by the Organiser and have not therefore been considered as false positives. No z-score value has been calculated for these results... False negatives Results for pesticides that were not reported by the laboratories, although they were used by the Organiser to treat the test material and were subsequently detected at, or above, the RPL by the Organiser (and the majority of participating laboratories) have been considered to be false negatives. z-cores have been calculated for all pesticides detected at levels exceeding the RPL.. Estimation of the assigned values To establish the assigned values, the median levels of all the reported results, excluding the outliers, were used. Individual results without any absolute values reported, such as detected (), could not be used.. Estimation of the target standard deviation To assign the target standard deviations (σ) for each individual compound a fixed relative standard deviation (fit-for-purpose, FFP), based on individual experience and as recommended by the Advisory Group, was used. The target standard deviation was calculated by multiplying these FFP s by the assigned value... Fixed target standard deviations (fit-for-purpose) The target relative standard deviation (R) was considered to be %, as recommended by the Advisory Group, and also as a conclusion from the discussion session on proficiency testing at EPRW 00 in tockholm, weden. The same target R has thus been applied to all the pesticides.. z-cores A z-score for each laboratory/pesticide combination was calculated according to the following equation: z = (x-x) / σ Eq. Where: - x is the participant reported result or the RPL for those labs not having detected the pesticide present in the sample - X is the assigned value or true concentration - σ is the target standard deviation (using the median and FFP of %) Final Report- European Commission s Proficiency Test 7, 00 9

14 Any z-score values of /z/ > has been reported as +, or -. No calculation of z-score has been performed for any false positive result. For false negatives, the RPL has been used to calculate the z-score.. Combined z-scores In order to evaluate each laboratory's overall performance, and taking into account all the pesticides analysed, three methods were used to combine z-scores; the re-scaled sum of z-scores (RZ), the sum of squared z-scores (Z) and the procedure for combining z-scores called the Weighted sum of z-scores (WZ) that was first used in EUPT... RZ The RZ was calculated for all z-score values for each laboratory according to: RZ = Σ z / (n) / Where n is the number of z-scores The RZ gives an averaged score for all pesticides analysed and indicates if a laboratory has a consistent bias in its results... Z The Z is the sum of all squared z-scores. It was calculated for all z-scores for each laboratory according to: Z = (z-score ) + (z-score ) +...(z-score n ) Where n is the number of z-scores... Weighted sum of z-scores This function was only applied to labs with sufficient scope (those in Category A), i.e. those labs that have reported or more results with no false positives. The weighted function ω is defined as follows: ω Z = if if if Z < Z Z > Therefore, the Weighted sum of z-scores z formula is: Weighted sum of z-scores z = n i= Ziω( Zi) n 0 Final Report- European Commission s Proficiency Test 7, 00

15 o for each lab the formula will have three terms: The first term is the sum of absolute values of z-scores between zero and two, multiplied by one. The second term is the sum of absolute values of z-scores greater than two, but less than or equal to three, multiplied by three. The third factor is the sum of absolute values of z-scores greater than three, multiplied by five. The sum is then divided by the number of reported results (n) from each lab. The Weighted sum of z-scores' has then been used to produce an overall classification of laboratories as good, satisfactory or unsatisfactory according to: z good < z < satisfactory z > unsatisfactory In this way, a simple, single combined value, very similar to the single z-scores, is produced that should help to encourage laboratories to analyse a greater number of target compounds. This evaluation has not been applied to those participants with insufficient scope, in Category B, which is for the laboratories reporting less than results, or with any false positives. Final Report- European Commission s Proficiency Test 7, 00

16 . REULT. ummary of reported results One hundred and twenty-eight laboratories agreed to participate in this proficiency test and one hundred and twenty-five submitted results. The results of the one hundred twenty-five participating laboratories are presented in this report. A summary of the results reported can be seen below in Table.

For an explanation of the symbols used in these tables, see Annex... False positives ome laboratories reported additional pesticides to those applied to the test material. These pesticides and their residue levels reported are presented in Table A and B. Final Report- European Commission s Proficiency Test 7, 00

17 When the reported concentration of the erroneously detected pesticide was higher than the assigned RPL value the result was considered to be a false positive (see table A). No laboratory was classified as Category B solely because it reported a false positive result. Table A. Laboratories that reported false positives in the treated test material Pesticide Lab Code Concentration (mg/kg) RL (mg/kg) RPL (mg/kg) ichlofluanid EUPT Endosulfan EUPT ethidathion EUPT yclobutanil EUPT If the concentration was below the RPLs, or if the pesticides did not appear in the pesticide list included in the EUPT 7 (Annex l), then these results were not considered to be false positives. However, these laboratories should have taken more care in reporting their results as the concentrations reported were not only lower than the RPL but in most cases even lower to their own reporting limit. These can be seen in Table B: Table B. Laboratories that should take more care in reporting their results Pesticide Lab Code Concentration (mg/kg) RL (mg/kg) RPL (mg/kg) Chlorpyrifos EUPT ichlofluanid EUPT yclobutanil EUPT Vinclozolin EUPT False negatives Pesticides actually present in the test material but reported as not detected (N), were considered to be false negatives. Table summarizes how many N results for each pesticide were reported... istribution of data The distributions of the concentration of the sixteen pesticide residues reported by the laboratories have been plotted as histograms. ee Appendix. A few results fell outside the concentration scale. Final Report- European Commission s Proficiency Test 7, 00

18 . Assigned values and target standard deviations To establish the assigned values, the medians of all the reported results were used, excluding those values that were very distant from the median. The median did not change even when these outliers were included. The target standard deviation was obtained using a FFP value of %. The assigned values are given in Appendix.. Assessment of the laboratory performance.. z-cores z-cores were calculated using the FFP R given. The criteria for defining the acceptability of the z-scores are: z acceptable < z < questionable z > unacceptable In Appendix, the individual z-scores are presented, together with the median for each laboratory and pesticide. z-cores for false negatives results have been calculated using the RPL value. In Appendix, the graphical representations of the z-scores are presented excluding z-scores from false negatives.. Combined z-cores The classical combined z-scores: RZ and the Z values are listed in Appendix for all laboratories. Appendix shows a table with the values of individual z-scores for each pesticide and the new combined Weighted sum of z-scores (WZ) for those labs in Category A. In this category are the laboratories that reported or more results, and also did not report any false positives. A graphical representation of the results for these laboratories can also be found. ixty-four from the one hundred and twenty-five laboratories have been put into Category A (.%), from which 7% were classified as good,.7% as satisfactory and 0.% as unsatisfactory (Table ). ixty-one of the one hundred and twenty-five laboratories reported results for less than fourteen pesticides. everal of these labs could also have been classified as good, but they failed to report results for the required compounds. Twenty-two of the sixty-one laboratories detected twelve or thirteen pesticides. For Category B, Table gives the number of pesticides reported by each laboratory and the number of results, for which their z-score was acceptable.

22 . CONCLUION A large number of the invited laboratories submitted results for the analysis of the pesticides present in the grape homogenate test material ( of 8). For each laboratory/pesticide combination, z-scores based on FFP were calculated. For the FFP, a graphic representation has been prepared. A classification was made using the simple descriptive terms acceptable, questionable and unacceptable. The Weighted um of z-cores (WZ), a criterion first introduced in last year s proficiency test report, was used to demonstrate the overall performance of the laboratories. Those laboratories reporting fourteen or more results, and not having submitted any false positive results, were classified as having sufficient scope and were therefore placed in Category A. Those laboratories that reported less than fourteen results were considered to have insufficient scope and were placed in Category B. Laboratories in Category A were also classified as good, satisfactory or unsatisfactory, depending on the values obtained after combining each reported z-score. For the remainder of the labs (the ones belonging to Category B) no combined weighted sum of z-scores was calculated. However, the number of satisfactory z-scores is shown. The median value of each pesticide, after elimination of outliers, was used to obtain the assigned or true concentration, which was also used to calculate the z-scores.. Applying the factors for recovery correction did not improve the overall precission and accuracy of the results. The presence of some very low level residues in the blank grape homogenate supplied did not affect the results obtained from the treated test material. Three of the sixteen pesticides used to treat the test material were not included in the monitoring priority list. Acetamiprid and Tetraconazole were considered to be important because of their wide usage in agriculture and the frequent occurence of RL-violations. onocrotophos, was chosen because of its high toxicity. The decrease in the numbers of false positive and false negative results seen in PT was even more apparent in PT7. However, this continued improvement may have been, at least in part, due to some labs that performed poorly in PT did not participate in PT7. Another reason for the improvement could have been that more participants used mass spectrometry, particularly /. Participation in this year 7 th European Proficiency Test involved EU member states, the EU-candidate country Romania, and also Iceland and Norway that regularly participate in the EU-monitoring programmes. This year some laboratories participated for the first time in this Proficiency Test. 8 Final Report- European Commission s Proficiency Test 7, 00

23 . UGGETION FOR FUTURE WORK The cientific Committee and Advisory Group of the EU Proficiency Test 7 decided to maintain the use of the % FFP standard deviation, so that the results from the PTs are more comparable. After this 7th EU Proficiency Test, we believe that it is time for a recapitulation. Recalculating previous PT results using the % FFP standard deviation would help to obtain more comparable data and clear information about the trends in the performances of the laboratories throughout all the PTs. This would also help to present a picture of the overall progress in achieving better analytical quality and harmonization within the EU. Final Report- European Commission s Proficiency Test 7, 00 9

341 ANNEX. Protocol and Instructions. List of pesticides to be sought. Only laboratories that are involved in providing residue data for their national monitoring programmes, and/or the EU co-ordinated monitoring programme are invited to participate in the 7 th European Proficiency Test. To participate, each laboratory will have to send by the Application Form to the Organiser. They will then receive confirmation of acceptance of their participation by with a web security code to enable them to access the Protocol, the Forms and the Pesticide List. A Laboratory Code will also be sent and subsequently this code must always be used in communications with the Organiser. Any without this code will not be answered. This code will only be known by the participant, the Organiser, and the Commission. This will ensure confidentiality during the test. In the Final Report there will not be any correlation between the code and the laboratory name. However, some results may need to be presented on a country basis to the tanding Committee on the Food Chain and Animal Health, and a link between codes and laboratories is possible, especially if there are only a few laboratories in one country. This Protocol, together with three Forms (-) will be uploaded onto the web page and access will be using the security code. Each form will have a deadline; please ensure you adhere strictly to these deadlines. The completed forms must be returned to the Organiser. On receipt of each form, the Organiser will respond with a confirmatory . The Pesticide List will also be present at this site without using the security code. This list will include all the possible pesticides that could be present in the test material. This list will specify which compounds to look for. The list will be available from 9 th arch 00, so that all participants know in good time before receipt of the test materials which pesticides might be present. Thus, participants will have time enough to buy any standards required and validate their methods. PRL values (minimum performance reporting levels) for each pesticide will be given. These values are the levels that the laboratories should be able to attain. The official language used in this Proficiency Test will be English. Communications between participating laboratories during the test are not allowed. Invoices to cover the cost of transporting the test materials will be available from the start of the test, so that once the shipping begins laboratories will be able to receive the test materials. Only laboratories that have paid the transport costs will receive the test materials. If laboratories need more time to pay, they must send by fax a justification to verify that the payment procedure has started. Final Report- European Commission s Proficiency Test 7, 00 7

342 ANNEX. Protocol and Instructions. List of pesticides to be sought. The objective of this proficiency test is to obtain information about the quality, accuracy and comparability of the pesticide residue data sent to the European Commission in the framework of the EU and national pesticide monitoring programmes. Participating laboratories will be provided with an assessment of their own analytical performance and the reliability of their data compared to other laboratories. The Proficiency Test is made up of the following 8 steps that are essential for the generation of satisfactory results:. Invitation to the participating laboratories. Also supplying details of the web site & web page where they can download the Application Form.. Preparation of the test materials. Homogeneity and stability testing performed by the Organiser.. Confirmation of the receipt of the participants Application Form and supplying the Laboratory Codes and security code to access to the Pesticide List, the Forms and this Protocol.. Payment in advance for the shipment of the test materials, or receipt of a fax demonstrating that the payment procedure has started.. hipment of the test material, together with the blank.. The participant laboratories will be responsible for reporting their data to the Organiser using the Forms supplied by the stipulated deadline. 7. The Organiser will evaluate the results at the end of the proficiency test, once the deadline for receipt of results has passed. 8. The Organiser will send a copy of the Final Report to each participant laboratory. This report will include information regarding the design of the test, the homogeneity and stability test results, a record of the shipped samples, a statistical evaluation of the participant s results, graphical displays of the results and conclusions. Any other relevant information considered of value will also be included. 8 Final Report- European Commission s Proficiency Test 7, 00

343 ANNEX. Protocol and Instructions. List of pesticides to be sought. The statistics used for the treatment and assessment of the data will be described in detail in the Final Report. A short summary of how the results will be treated is given below. The results will be grouped into: False Positives These are the results that show the presence of pesticides which are listed in the pesticide list and which are (i) not used in the sample treatment, (ii) and not detected by the organizer even in a repeated analysis. However, if a number of laboratories detect the same additional pesticide, or if the concentration is close to the PRL, then a decision as to whether or not this should be considered to be a false positive result will be made on a case-by-case basis. Nevertheless, any results reported that are lower than 0.0mg/Kg will be ignored by the Organiser and will not therefore be considered as false positives. False Negatives These are results for pesticides that were not reported by the laboratories although they were used by the Organiser to treat the test material and are detected at, or above, the PRL. Establishing the true concentration (μ) The true concentration in all cases will be determined by the median of all the results. Therefore there will be a median value for every pesticide present. Establishing the assigned value for the standard deviation The assigned value for the standard deviation (δ) will be fixed by the Organiser. Where δ = b i * μ i being b i = %FFP/00% An assigned value will be established based on the Fit-For-Purpose (FFP) tandard eviation model. An average fixed value of % has already been chosen. However, the Organizer may increase this value for certain difficult pesticide-crop-concentration combinations, after consultation with the committee of experts, and based on experience gained from previous Proficiency Tests. Final Report- European Commission s Proficiency Test 7, 00 9

344 ANNEX. Protocol and Instructions. List of pesticides to be sought. z-cores This parameter is calculated using this formula: z i = (x i μ i ) / δ i where x i is the value reported by the laboratories, μ i the assigned value and δ i the standard deviation at that level, for each pesticide ( i ). Any z-score values of /z/ > will be reported as +, or -. z-core values will be interpreted in the following way: /z/ acceptable < /z/ questionable /z/ > unacceptable For the values considered to be false negative results, z-scores will be calculated using the PRL values as the value for x i. However, a z-score will not be assigned to any false positive results. The organizer will consider whether, or not, these values should appear in the histograms. Combined z-core values Taking into account all the pesticides analysed, two ways will be used to combine their z- scores: the re-scaled sum of z-scores (RZ), and the sum of squared z-scores (Z). The equations are: RZ = Σz/(n) / Z = Σz n = number of detected pesticides These formulas will only have informative purposes and will not be used for laboratory evaluations. In order to evaluate each laboratory s performance, only those laboratories that have reported at least 90% of the pesticides present, and have reported no false positive results, will be classified according to the Weighted um of z-cores. A fixed maximum value of will be used as a default z-score using the following formula: Weighted um of z-cores (Z) = i z + z + i = 0 i i> i> n z. n = number of detected pesticides 0 Final Report- European Commission s Proficiency Test 7, 00

The second factor is the sum of all their /z-scores/ greater than two but less than or equal to, three, multiplied by three. The third factor is the sum of all their z-cores greater than three, multiplied by five. These weighted summed z-score results are considered to be less important than the individual z-scores.

346 ANNEX. Protocol and Instructions. List of pesticides to be sought. This proficiency test is based on pesticide residues analysis in grapes. The grapes were grown in Almería, pain. The pesticide treatments will be carried out as a post harvest treatment using commercial formulation in micro spray solutions. The test material will be frozen (using liquid nitrogen), chopped, homogenized and sub-sampled into polyethylene bottles that have previously been coded. Ten of these bottles, containing the test material, will be chosen randomly and analysed by an independent laboratory to check for homogeneity. The test material will be stored frozen ( 0ºC) prior to shipment to participants. Two bottles, again chosen randomly, will be analysed over a period of time to confirm the stability of the pesticides in the test material (firstly when the test materials are shipped, and then a few days after the deadline for receipt of results from the participants). These results will not be included in the statistical analysis of the proficiency test. The aim is only to check the stability during the shipping process and the proficiency test.

It is up to the participants to fill in and return the Application Form so the Organiser has all their details before the deadline. The Organiser will not be responsible if a laboratory does not receive notice of the web page address necessary to take part in the test. Approximately 00g of grapes test material will be shipped together with 00g of blank grapes surrounded with dry ice and packed in boxes. The courier costs are charged and must be paid by the participants before shipment of the samples. There will only be a limited amount of test material and laboratories should not ask for more than they require to perform the analysis. Using the web page site: the participating laboratories must complete the application form and return it by to the Organiser. In the Application From there is also information that must be provided in order to make an official invoice. The Application Form must be sent to the Organiser by 7 th arch 00, at the latest.

348 ANNEX. Protocol and Instructions. List of pesticides to be sought. The shipment of the test materials will be carried out during a two-week period because of the differences in the time that it takes to reach the different participant countries (from - days). A warning message will be sent out a the week before shipment, and laboratories must make arrangements for the reception of the test materials. They should let the Organiser know of any possible public holidays in their country/city during the delivery time mentioned in the calendar and make every effort to receive the shipment even if the laboratory is closed. Once the laboratory has received the test materials they must complete Form, filling in the date of receipt, the condition of the test material, and its acceptance. Form has a deadline, so if it is not returned by latest th April 00, the Organiser will assume the laboratory has received and accepted the test material. Please note that you must include the laboratory code assigned to you on this form. ignificant Figures The results must be expressed in mg/kg in the following way: concentrations <0.00 mg/kg, to be expressed to two significant figures (three decimals places, i.e. 8 mg/kg). concentrations > 0.00 mg/kg, to be expressed to three significant figures, i.e. 0.,., 0. mg/kg. In cases where a pesticide was not detected, it should be recorded as N. If it was not sought, it should be recorded as. The results/concentrations must be reported as numbers. Any other form of data will not be considered. Final Report- European Commission s Proficiency Test 7, 00

349 ANNEX. Protocol and Instructions. List of pesticides to be sought. The results must not be corrected using recovery factors. If the laboratory usually corrects the results for their recoveries, they should provide the correction factor used for each pesticide as informative data only. This information must be sent together with the results in Form. The test material contains a certain number of pesticides from the Pesticide List. Please read carefully the list in Form since the residue definitions are not given (see the Pesticide List). It should not be assumed that only pesticides registered for use on grapes will be present. Each laboratory must report only one result for each of the pesticides present in the test material, using their normal routine analytical procedure(s). This does not mean that more than one method has to be used to cover all the compounds present. The analytical procedure used must be reported using Form.
