Surface exchange and transport processes governing atmospheric PCB levels over Lake Superior
Article Abstract:
Atmospheric polychlorinated biphenyl concentrations measured at Eagle Harbor, MI, from 1990-1994 were analyzed to determine the importance of regional air/water exchange flux as a determinant of PCB concentration over Lake Superior. Results derived from congener-specific regression analyses of log concentration against reciprocal temperature are highly dependent on the time of the year, during periods of onshore flow. When the lake is colder than the overlying air, 48% to 63% of the variance in log C is explained by regressions for onshore flow.

Polychlorinated biphenals and polychlorinated naphthalenes in Swedish sediment and biota: levels, patterns and time trends
Article Abstract:
Polychlorinated dioxins and furans have been established as major toxicological threats to the environment. Polychrorinated biphenyls (PCBs) and naphthalenes (PCNs) exhibit similar toxic effects although environmental studies on PCNs are lacking. The Swedish Dioxin Survey, 1988 established PCNs and PCBs widespread in the local aquatic environment. Birds preying on Baltic Sea fish suffer heavy contamination compared with sea mammals that do not appear to concentrate these compounds.

Polychlorinated biphenyls and nonylphenols in the Sea of Japan
Article Abstract:
Deep water and shallow coastal water vertical profile studies were undertaken in areas in the Sea of Japan to determine the extent of marine pollution and study vertical water movement. Monitored in the experiments were the concentrations of polychlorinated biphenyls and nonylphenols. A characterization of the vertical distribution of the chlorinated biphenyls showed a turnover mechanisms which allows the dense surface waters to sink to the bottom during the strong winter months.
