- 252 - Bioavailability Changes in Sediments and Bioaccumulation in Fish -- Ghosh
Release Date: 12/02/2015
Changes in uptake of polychlorinated biphenyls (PCBs) in fish after remediation of their aquatic environment may be predicted, according to researchers at the University of Maryland, Baltimore County. They measured freely dissolved concentrations of PCBs in water and applied mathematical models to predict the effectiveness of sediment remediation. The study is one step toward understanding how PCB bioavailability changes in sediment as a result of activated carbon amendments, a method to sequester PCBs, can influence transfer of PCBs to fish.
