1 NORMAN working group (WG) on emerging substances in the indoor environment NORMAN Annual General Assembly Meeting Amsterdam, 9-10 December 2014 Eva Brorström-Lundén, IVL Pim Leonards, IVM Adrian Covaci, UA

2 Kick off meeting in the NORMAN working group (WG) on emerging substances in the indoor environment 8-9 December 2014 Eva Brorström-Lundén, IVL Anna Palm Cousins, IVL Pim Leonards, IVM Jana Weiss, IVM Luisa Lucattini, IVM Adrian Covaci, UA Pernilla Bohlin Nizzetto, NILU Peter Haglund, UmU Cynthia de Wit, ITM, SU Jana Klanova, RECETOX Lisa Melymuk, RECETOX Stellan Fischer, KemI Valeria Dulio, INERIS Marc Durif, INERIS Jaroslav Slobodnik, EI

3 Emerging substances in the indoor environment Background Articles and consumer products used indoors may contain a variety of both well-known chemicals and emerging substances Chemicals are emitted indoors, and indoor air and dust is an important pathway of chemical exposure for humans but could also be a source for exposure to the outdoor environment We spend in average 85-90% of our time indoors

4 Emerging substances in the indoor environment Sources Building materials Combustion Articles and chemical products Indoor emissions Gas Particles Air Indoor emissions Particles (dust) Models Sampling strategy Measurements Sampling methods & Analysis Actions Human exposure Storm water/waste water Emissions to the environment Air (gas particles)

5 Emerging substances in the indoor environment Groups of relevant semi volatile organic compounds (SVOCs) indoor contaminants Flame retardants (halogenated and non-halogenated...) Plasticizers (e.g. phthalates, adipates, citrates...) BPA and other plastic monomers Antioxidants (in plastics, based on aniline or t-butylphenols) Substances in personal care products (!!)...and more...and also focus on unknows 10

6 Kick off meeting in the working group on emerging substances in the indoor environment The overall aim is to establish the NORMAN WG on the indoor environment and to identify the objectives for the WG

7 Activities in the working group on emerging substances in the indoor environment Identification of chemicals and chemical groups of concern for the indoor environment and investigate which emerging chemicals that are analysed in indoor air and dust Emissions of emerging substances indoors e.g. from products and articles and identification of important pathways of chemical exposure for humans indoors and pathways to the outdoor environment via air or WWTPs Harmonisation of sampling and measurement methods Interlaboratory studies (ILS): target and non-target screening in indoor dust Policy issues: Links between policy and research

8 Topics NORMAN WG indoor environment Prioritization NORMAN list of emerging compounds indoor environment Modelling Databases Policy -Air quality directive -Other related directives Sampling Design Pre-treatment Characterization Data From projects outside NORMAN NORMAN database Indoor environment projects Non-target screening

9 Time plan and Activities WG meeting- NILU workshop -before summer 2015 Harmonize protocols dust sampling and characterization NORMAN- Database Work on database requirements Non-target screening dust autumn 2015 in combination with INTERFLAB - evaluation during 2016 Organization ILS (non-)target screening dust/air based on protocol

10 Time plan and Activities A short report of a strategy for the indoor environment WG with a strategy and identify important issues and future aims for the working group - We welcome new members to the WG and to participate in the WG activities

11 Discussion points indoor environment WG Boundaries indoor environment WG Air Dust Ventilation : indoor-outdoor Emissions WWTP not included but considered Human samples not included but considered (end-point)
