This is a presentation on translating environmental risk assessment outputs to socioeconomic impact inputs under REACH that I gave in March 2010 to the Socieconomic Analysis Committee of the European Chemicals Agency in Helsinki.

1. Case studies to illustrate what environmental risk assessment can deliver for impact and socioeconomic analysis Mark Crane and Hans-Christian Stolzenberg 11 th March 2010 Workshop on health & environmental impacts in REACH SEA context

13. MCCP v LCCP aquatic toxicity MCCPs: Aquatic NOEC: 1 µg/L HC5: 5.53 (0.078-36.25) µg/L LCCPs: Aquatic NOEC: 2.9 µg/L HC5: 6.39 (0.004-70.89) µg/L

14. MCCP v LCCP sediment toxicity MCCPs: Sediment NOEC: 5 mg/kg Based on worm data (below) LCCPs: Sediment NOEC: 571 mg/kg Based on aquatic data and equilibrium partitioning estimate Can this be correct in light of MCCPs data? Comparisons between alternatives do not appear to be fair. Similar issues with agricultural soils and secondary poisoning via earthworms data.

16. Fair & consistent comparisons using Multi-criteria Analysis? Input data: Local compartment MCCPs LCCPs (C 18-20 liquid) 90 th ile PEC Toxicity value RCR 90 th ile PEC Toxicity value RCR Surface water (µg l -1 ) 8.7 5.43 (HC5) 1.6 0.027 6.39 (HC5) 0.0042 Sediments (mg kg -1 ) 200 202.5 (EC10) 0.99 240 202.5 (EC10) 1.19 Agricultural soils (30 day average; mg kg -1 ) 10 50.8 (EC10) 0.2 10 50.8 (EC10) 0.2 Secondary poisoning via earthworms (mg kg -1 ) 13 10 (NOAEL) 1.3 19 10 (NOAEL) 1.9
