| biological uptake of polychlorinated biphenyls by macoma balthica from sediment amended with activated carbon. | this work characterizes the efficacy of activated carbon amendment in reducing polychlorinated biphenyl (pcb) bioavailability to clams (macoma balthica) from field-contaminated sediment (hunters point naval shipyard, san francisco bay, ca, usa). test methods were developed for the use of clams to investigate the effects of sediment amendment on biological uptake. sediment was mixed with activated carbon for one month. bioaccumulation tests (28 d) were employed to assess the relationships between ... | 2007 | 17521146 |
