Outcome of the OECD workshop on metals specificities in environmental risk assessment
On 7-8 September 2011, the OECD organized a workshop in Paris on metals specificities in environmental risk assessment.
The goals of the workshop were to :
- Share regional experience in dealing with metal specific environmental hazard assessment
- Review proposed/existing guidance for metals/inorganic specific hazard assessment concepts
- Provide examples and encourage exchange of experience in dealing with metals environmental assessment
- Understand and apply metal and inorganic specific tools and approaches
- Collect feedback on the proposed concepts and identify opportunities for harmonisation of approaches across countries/regions
Concepts of bioavailability, effects assessments, fate and bioaccumulation specific to metals were presented with illustrative examples. Participants generally agreed with proposed concepts and recommended the development of further guidance on BLM application, on statistical approaches for SSD derivation, the application of more stringent relevancy criteria for the selection of test data, and further discussion on the interpretation of bioconcentration and bioaccumulation for metals.
Below are the presentations from speakers at the workshop:
Generic presentations :
Session A- Bioavailability
Session B- Effects assessment
Session C- Bioaccumulation and fate
