| Popis: | Laboratory toxicity tests were conducted for polychlorinated biphenyl (PCB)-containing sediment from Choccolocco Creek at the Anniston PCB Site. The objective of this investigation was to develop a site-specific PCB concentration–response relationship for invertebrate test organisms. Test results from reference locations were used to develop background-adjusted 10% (EC10*) and 20% (EC20*) effect concentrations for a range of survival, growth, and reproduction endpoints. The EC20* values ranged from 4.43 to 114 milligrams of PCBs per kilogram (mg/kg) of sediment on a dry weight basis for reproductive endpoints, 28 to 67.7 mg/kg sediment for growth, and 123 to 165 mg/kg sediment for survival. The aggregate EC20* response range for endpoints that demonstrated good test performance with reasonable ranges in control variability ( |
