Ecological considerations: Bioaccumulation assessment of organic chemicals
Citation:
Burkhard, L. Ecological considerations: Bioaccumulation assessment of organic chemicals. CLU-IN Contaminated Sediments Virtual Workshop, Duluth, MN, October 30, 2019.
Impact/Purpose:
A brief overview on the development pore water remedial goals (PWRGs) for the protection of benthic organisms and their application in relation to sediment toxicity testing results will be provided in US-EPA Contaminated Site Cleanup Information (CLU-IN), Contaminated Sediments Virtual Workshop Session 4 Long-Term Monitoring. The aim of the virtual workshop is to provide interactive discussions between expert panelists and workshop participants on Long-Term Monitoring at Superfund Sites. The brief presentation (10 minutes) will cover the development of PWRGs and their subsequent application in evaluating sediment toxicity testing data from Superfund sites.
Description:
At many Superfund sites with contaminated sediments, residues of organic chemicals in fish are the risk drivers for setting remedial goals at the site. Risks could be due to human (and in some cases, wildlife) consumption of shellfish and/or fish from the site or possibly, ecological risks to the fish themselves. Assessment of risks requires knowledge of bioaccumulation processes and the tools needed to do these analyses. In the workshop, bioaccumulation process and tools will be discussed.
