Effects of eutrophication on contaminant cycling in marine benthic systems
Article Abstract:
Research is presented on the interaction between hydrophobic organic contaminants (HOCs) and the blue mussel Mytilus edulis, the polychaete Nereis diversicolor, and the brittle star Amphiura filiformis. Macrofaunal feeding significantly affected benthic-pelagic HOC coupling, eutrophication increased the accumulation of HOCs in benthic species, bioturbation released sedimentary HOCs into overlying water, and temporal variations in organic carbon affected data on contamination levels.

Biological and chemical determination of contaminant levels in settling particulate matter and sediments: a Swedish river system before, during, and after dredging of PCB-contaminated lake sediments
Article Abstract:
Sediment samples taken before, during and after remediation of Sweden's Lake Jarnsjon showed the effectiveness of the procedure. PCB-contaminated sediment was dredged, dewatered and removed to a landfill. Although post-dredging sediment showed about 1% of dioxin-like activity compared to pre-dredging, elevated dioxin-like diaromatic compounds persisted in downstream water systems.
