1 1 st Open NoMiracle workshop, June 2006, Ispra Emission estimates for industrial chemicals as driving factor for scenario selection - Area distributed emission profiles for industrial chemicals Patrik Fauser Estimating and mapping emissions of industrial chemicals at the European Scale - Emission estimates are the logical starting point in risk assessment of chemicals - Emissions occur during all stages, from production, processing, use and disposal - Emissions vary greatly for different chemicals, due to chemical properties, production processes, products, use patterns and disposal - Especially for the industrial chemicals (semi-VOCs and VOCs) the variety of chemicals is very large - Emission estimates are often the most uncertain link in a risk assessment

2 1 st Open NoMiracle workshop, June 2006, Ispra Patrik Fauser Estimating and mapping emissions of industrial chemicals at the European Scale 1)Definition of chemicals to be included 2)Quantification of production and use amounts 3)Distribution of chemicals to products and activities 4)Quantification of emission factors for each chemical and use 5)Specify location of releases, and mapping A complete emission inventory includes:

3 1 st Open NoMiracle workshop, June 2006, Ispra Choice of chemicals A risk chemical can be defined as a chemical that occurs in concentrations that may cause unwanted effects on humans and/or the environment, analogous to the PEC/PNEC approach. Choice of chemicals is an important output of scenario selection procedure, and to make any subjective pre-selection would overrule an important objective in NoMiracle; Not be restricted by existing assumptions and judgements. However! Important and thorough work has already been done that contain very detailed knowledge, and this knowledge may be extrapolated to many more chemicals. Patrik Fauser Estimating and mapping emissions of industrial chemicals at the European Scale

4 1 st Open NoMiracle workshop, June 2006, Ispra Patrik Fauser Estimating and mapping emissions of industrial chemicals at the European Scale Choice of chemicals: Risk Assessment Reports (RARs)made for existing chemicals: 1) Produced and used amount of specific chemical in the EU 2) Names (locations) of producers and importers. No link is available between company name and produced/processed amount of chemicals 3) Products and uses that the chemicals are associated with. The use is categorised as use in closed systems, use resulting in inclusion into or onto matrix, non-dispersive use and dispersive use 4) Releases to wastewater, air, soil, surface water, sea/estuaries and landfills on a local scale (non-dispersive and wide-dispersive), regional and continental scale 5) PECs for the same compartments and spatial scales as above 6) Physico/chemical properties 7) Ecotoxicological and human toxicological parameters Four priority lists 141 chemicals, 77 RARs, 35 are used as training chemicals in NoMiracle

9 1 st Open NoMiracle workshop, June 2006, Ispra Patrik Fauser Estimating and mapping emissions of industrial chemicals at the European Scale Predicting emissions of not tested chemicals Define chemicals of interest Compile phys/chemical, production and use parameters for selected chemicals Run regression analysis for training set for a selected target parameter. Identify predictor parameters Use predictor parameters for chemicals of interest to identify target parameter value Important to note that the predicted values are based on best available existing information. The method will suggest candidates for more in-depth emission inventories

14 1 st Open NoMiracle workshop, June 2006, Ispra Patrik Fauser Estimating and mapping emissions of industrial chemicals at the European Scale Examples of mapping emissions to wastewater Styrene is exclusively used as a monomer in the production of various polymer products, such as polystyrene. Contrary to the other two chemicals styrene is incorporated in a solid matrix in products used for packaging, building, transport and even clothing. The content of styrene residuals in polymers and copolymers is approximately 0,04% of the used monomer amount. Releases are predominantly associated with the local scale in the vicinity of the processing industries, where high releases to air and wastewater can be found. C10-13 alkyl derivatives of benzene, are only used as intermediates in the production of linear alkylbenzene sulphonate (LAS), that is used as a household detergent, and is released to wastewater. The use is wide-dispersive.
