| Short Description |
During 2002, the Washington State Toxics Monitoring Program analyzed 12 samples of fish tissue from eight sites for a variety of toxic contaminants. PCBs and PCDD/Fs frequently exceeded criteria for the protection of human health while levels of DDT, dieldrin, and mercury showed fewer exceedances. Other contaminants found were chlordanes, hexachlorobenzene, pentachloroanisole, methoxychlor, and PBDEs. Water samples from nine sites were analyzed for 115 pesticides; 17 pesticides were detected at low levels and low frequencies. Recommendations include (1) evaluating potential human health risks from consumption of contaminated fish, and (2) placing six sites in Category 5 of Washington′s 303(d) list.

| Abstract | Long Description |
The goal of the Washington State Toxics Monitoring Program is to investigate the occurrence and concentrations of toxic contaminants in edible fish tissue and surface waters from freshwater environments in Washington. This program was started in 2001 by the Washington State Department of Ecology due to increasing concerns about contaminants in our environment. During this 2002 exploratory monitoring effort, 12 composite samples of edible tissue were analyzed, representing six species collected from eight sites. Levels of PCBs and PCDD/Fs in fish tissue frequently exceeded criteria for the protection of human health, while levels of DDT, dieldrin, and mercury showed fewer exceedances. Other contaminants detected in fish tissue were chlordane compounds, hexachlorobenzene, pentachloroanisole, methoxychlor, and PBDEs. Water samples collected from nine sites were analyzed for 115 chlorinated, organophosphorous, and nitrogen pesticides. Seventeen pesticides were detected at low levels and low frequencies. The most frequently detected pesticides were diuron, dichlobenil, bromacil, diazinon, and the herbicide breakdown product 2,6-dichlorobenzamide. Two results for diazinon exceeded a chronic criterion for the protection of aquatic life. Recommendations include (1) evaluating potential human health risks from consumption of contaminated fish, and (2) placing six sites in Category 5 of Washington′s 303(d) list. |
