| Abstract | Long Description |
In an effort to determine if a chemical contaminant might be responsible for physical abnormalities observed during a 1992 tagging study on rainbow trout in lower Douglas Creek, water, sediment, and fish tissue samples were collected and analyzed for metals, pesticides, PCBs, and PBDEs. A fairly extensive series of chemical and biological analyses failed to identify a toxicant as being the cause of abnormalities in Douglas Creek rainbow trout. The level of chemical contamination in the creek appears very low. In light of this finding and the reported long-term stability of the trout population, further chemical investigation is not recommended at this time. Note about PBDEs: Because PBDEs were found in the initial screening of Douglas Creek tissue samples, additional archived tissue from the Yakima, Spokane, Snake, Columbia, and Soleduck rivers, and Rock Island Creek were analyzed for the compound. The results are discussed in more detail in publication 01-03-033. Sixty-five fish collected from the Spokane River for a 1999 PCB and Metals survey were also analyzed for PBDEs at the same time. The results for six of these fish appear in publication 01-03-033. The remaining results do not appear in any publication but are contained in EIM under project ID AJOH0022. |
