Sublethal effects in caged rainbow trout during remedial activities in Lake Jarnsjon
Article Abstract:
Rainbow trout were used to test subchronic PCB exposure during remediation of Lake Jarnsjon in Sweden. Examinations were conducted for fin erosions, skin and liver lesions, and liver ethoxyresorufin-O-deethylase (EROD) activity. Two years after remediation, the trout in Jarnsjon showed slightly induced EROD activity, but trout downstream had more pronounced EROD activity. This indicates PCB contaminant transport after remediation.

Remediation of PCB-contaminated sediments in Lake Jarnsjon: investigations, considerations and remedial actions
Article Abstract:
New landfill management techniques are helping the environmental remediation of Lake Jarnsjon in Sweden. Lake sediments contaminated with PCB were dredged and used to form a landfill. A geotextile screen divides heavily contaminated sediments from slightly contaminated ones, enhancing the ease of future cleanup efforts. No increase in PCB concentrations have occurred in either the lake or the groundwater under the landfill.

The remediation of Lake Jarnsjon: project implementation
Article Abstract:
The 1993-1994 remediation of Sweden's Lake Jarnsjon focused on dredging and landfill procedures. A geotextile screen prevented the spread of PCB-contaminated sediment, which was dredged with suction. The sediment was dewatered with filter presses, consigned to landfill, and covered with sand and gravel. This landfill technique does not require external hydraulic barriers.
