Accumulation of polychlorinated biphenyls (PCBs) in navigation channels, harbors and industrial areas of the Bahia Blanca Estuary, Argentina

The usage and production of polychlorinated biphenyls (PCBs) was banned in Argentina in 2002, approximately twenty to thirty years later than in other countries. A total of 29 sediment samples (up to 14 m deep) were analyzed for a mix of seven individual PCBs in a time series for over more than one...
