| Short Description |
During 1995, the Washington State Department of Ecology conducted a survey of chemical contaminants in bottom sediments from 29 areas throughout Salmon Bay. Sediments were analyzed for metals (arsenic, cadmium, chromium, copper, lead, mercury, nickel, and zinc), semivolatile organics, PCBs, and butyltins. Chemical data were compared to earlier studies in the basin and areal distributions were evaluated. Data were also compared to criteria to assess potential effects on aquatic organisms. Recommendations for further actions are included. (Also see abstract below) | |||

| Abstract | Long Description |
During 1995, the Washington State Department of Ecology conducted a survey of chemical contaminants in bottom sediments from 29 areas throughout Salmon Bay. Sediments were analyzed for metals (arsenic, cadmium, chromium, copper, lead, mercury, nickel, and zinc), semivolatile organics, PCBs, and butyltins. Chemical data were compared to earlier studies in the basin and areal distributions were evaluated. Data were also compared to criteria to assess potential effects on aquatic organisms. Recommendations for further actions are included. The survey was the second phase in a study of Salmon Bay: Phase I study evaluated the potential for contamination based on visual observation of sediments; Phase III will likely include both intensive chemistry and bioassay testing in contaminated areas. The overall objectives of the Salmon Bay study are to delineate areas of contaminated sediments, evaluate their toxicity, identify the contaminants contributing to sediment toxicity, and if possible, identify likely historical and current sources of contaminants to the problem areas. |
