| Description | Legacy chlorinated pesticides and breakdown products were analyzed in 48 fish fillet samples collected from 28 background lakes across Washington State. The data were collected to help prioritize 303(d)-listed waterbodies for water cleanup plans and support revisions to the water quality standards for chlorinated pesticides. The most frequently detected compounds (80% or more of samples) included 4,4’ isomers of DDT and its breakdown products DDE and DDD, dieldrin, chlordane components, hexachlorobenzene, and mirex. 4,4’-DDE occurred in the highest concentrations and increased moving from western to eastern Washington, a pattern not seen for any of the other pesticides. A number of the lakes sampled in the background study could qualify for 303(d) listing if higher fish consumption rates were adopted in the water quality standards. |
