| Short Description |
A reconnaissance survey was conducted to refine the target analyte list, analytical methods, and field sampling techniques for the biota and sediment sampling portion of the Washington State Pesticide Monitoring Program. Fish and/or sediment samples were collected from seven freshwater sites in September and October of 1992. (Also see abstract below) | |||

| Abstract | Long Description |
A reconnaissance survey was conducted to refine the target analyte list, analytical methods, and field sampling techniques for the biota and sediment sampling portion of the Washington State Pesticide Monitoring Program. Fish and/or sediment samples were collected from seven freshwater sites in September and October of 1992. Fish tissue samples were analyzed for 42 pesticides and breakdown products, including chlorinated pesticides and organophode Mountains, irrigated and dry-land agricultural use east of the Cascades, urban use, and use in forest practices. Samples were analyzed for 162 pesticides and breakdown products in the following chemical groups: chlorinated pesticides, organophosphorus pesticides, nitrogen-containing pesticides, pyrethroid pesticides, chlorinated herbicides, and carbamates. Conventional parameters included total suspended solids, total organic carbon, conductivity, nitrate+nitrite, temperature, pH, and flow. A total of 38 pesticides and breakdown products were detected. The most frequently detected pesticides were the herbicides DCPA (Dacthal), simazine, atrazine, and 2,4-D. Washington State and/or EPA aquatic life criteria were exceeded at five sites. Pesticides above criteria were DDT, DDE, DDD, azinphos-methyl (Guthion), and chlorpyrifos (Dursban, Lorsban). Concentrations of four additional compounds exceeded National Academy of Sciences (NAS) recommendations to protect aquatic life and wildlife. Mevinphos (Phosdrin) was detected in Joe Leary Slough at a concentration that is acutely toxic to many fish and aquatic invertebrates. |
