Long-term variations of PCB in the water of a river in relation to precipitation and internal sources
Article Abstract:
The concentration of polychlorinated biphenyls (PCB) in river water varies according to the season. The study of PCB concentration in the Eman River in Sweden was analyzed in relation to variances in factors such as temperature, suspended matter concentration, and water discharge levels. During high-water discharge, PBC concentration in the water approached precipitation levels, but during low water discharge PCB concentration was determined by internal sources.

Uptake of PCBs in fish in a contaminated river system: bioconcentration factors measured in the field
Article Abstract:
The concentration and domain distribution of polychlorinated biphenyls (PCB) in water and fish in Sweden's Eman River was investigated. The river system was contaminated by a small lake that contains approximately 400 kg of PCB in the sediment. It is shown that PCB concentration was 12 times greater in the outlet from the lake as compared to water upstream. The polluted lake had an impact on domain distribution in both water and fish.

PCB concentration in fish in a river system after remediation of contaminated sediment
Article Abstract:
Changes in PCB background exposure influenced the reduction of PCB levels found in fish following remediation. The concentration of PCB in fish was halved from 1991 to 1996, and the concentration of PCB in water fell from 8.6 ng/L to 2.7 ng/L in a study of a lake in southern Sweden.
