Mutagenic Activity of Water Extract (Appendix G) Number of Revertants per Plate Salmonella typhimurium TA98 S9 - Blank Sample Extract Positive Controls 44, 45, 9 27, 25, , 756, ± ± ± 43.5 NPD (20mg) + 35, 38, ± , 32, ± , 1891, ± AF (20mg) Salmonella typhimurium TA , 104, ± , 92, ± , 672, ± 48.0 Azide (1.0mg) + 147, 91, ± , 71, ± , 656, ± AF (20mg) Salmonella typhimurium TA , 291, ± , 354, ± , 2340, ± Mitomycin C (2mg) + 314, 350, ± , 328, ± 11.9 Comments S9 was used as a metabolic activator. NPD (4-nitro-o-phenylenediamine), Azide, and Mitomycin C are specific positive controls for strains TA98, TA100 and TA102 respectively while 2 - AF (2-aminofluorene) when used in conjunction with S9 is a positive control for both TA98 and TA100 The product passed the requirements of clause 6.6 when tested at an exposure of Michael Glasson Page 7 of 8

8 CLAUSE 6.7 Method of Analysis Extraction of Metals prepared using 1000 ml volumes of 50 hardness water. Extraction of Metals (Appendix H) All methods used to determine concentrations of metals are based on those described in the 21st edition of Standard Methods for the Examination of Water and Wastewater published by the APHA, AWWA and WEF (2005). The methods have been adapted for the instrumentation in use at the Australian Water Quality Centre. Concentration of the metals described in Table 2 of the AS/NZS 4020:2005 are determined as follows: Antimony, Arsenic, Barium, Cadmium, Chromium, Copper, Lead, Mercury, Molybdenum, Nickel and Selenium by inductively coupled plasma mass spectrometry. Silver by graphite furnace absorption spectrophotometry (Varian). Final Extract Antimony Arsenic Barium Cadmium Chromium Copper Lead Mercury Molybdenum Nickel Selenium Silver Limit of Reporting Blank < <0.001 < < <0.003 < < < < < <0.003 < Test 1 Test 2 < < <0.001 <0.001 < < < < <0.003 <0.003 < < < < < < < < <0.003 <0.003 < < Max Allowed The product passed the requirements of clause 6.7 when tested at an exposure of Dzung Bui Page 8 of 8
