Total impact? Changing? § How is the impact of chemicals changing? § Better? § Worse? § Method and data?

PRTR - goldmine of data! § But cooperation between organisations and professions was needed § Basis for the work

Method § Data from E-PRTR (Sweden) Releases to air and water § Reallocation to products using System of Environmental Accounts (SEEA) § Life Cycle Impact Assessment (LCIA) by USEtox to retreive impact from industry and products - Human toxicity - Freshwater ecotoxicity

Results: Substances-human toxicity Substance CTUh kg Zinc and compounds (as Zn), air 370 Zinc and compounds (as Zn), water 120 Mercury and compounds (as Hg), air 91 Arsenic and compounds (as As), water 39 Chromium and compounds (as Cr), air 34 Lead and compounds (as Pb), air 28 Chromium and compounds (as Cr), water 21 Arsenic and compounds (as As), air 8. 3

Results: Industries-human toxicity Architectural an. . . Man. of coke an. . . Waste collection. . . Man. of non-. . . Electricity, gas e. . . Mineral extracti. . . Water supply an. . .

Discussion and conclusion § Dominance of metals - Characterization factors - Persistent - Often measured § Agriculture in general is lacking data § Yes – method to estimate chemical impact § More work is needed – add more data § Ongoing project financed by Swedish EPA to continue the work
