| Short Description |
Priority pollutants/hazardous substances list compounds and resin acids were analyzed in 12 sediment samples collected at five lower Columbia River ports and an upstream reference area during September 22-24, 1987. Potential for sediment toxicity was assessed through bioassay with two crustacean species, Hyalella azteca (amphipod) and Daphnia pulex (cladoceran). Ports included in the survey were Camas, Vancouver, Kalama, Longview, and Ilwaco. (Also see abstract below) | |||

| Abstract | Long Description |
Priority pollutants/hazardous substances list compounds and resin acids were analyzed in 12 sediment samples collected at five lower Columbia River ports and an upstream reference area during September 22-24, 1987. Potential for sediment toxicity was assessed through bioassay with two crustacean species, Hyalella azteca (amphipod) and Daphnia pulex (cladoceran). Ports included in the survey were Camas, Vancouver, Kalama, Longview, and Ilwaco. Results suggest the level of chemical contamination to be generally low. The sediments were not toxic in bioassay. Additional sampling is recommended to confirm the high concentration and evaluate the extent of polyaromatic hydrocarbons in sediments below the Reynolds aluminum smelter at Longview and possible elevated polychlorinated biphenyls below Reynolds and the VANALCO smelter in Vancouver. |
