Polychlorinated biphenyls in the Hudson river

This paper reviews studies of recent trends in the distribution of PCBs in water, sediment and fish of the Hudson River, New York. Results of various monitoring programs conducted since 1977 are presented. Elimination of direct discharge, dredging and disposal of contaminated sediments, and stabilization of banks have resulted in reduced levels in sediments and biota. The implications for commercial and recreational fishing interests are discussed. 41 references.
