Persistence of DDT in the Yakima River Drainage, WashingtonEntry ID: BESTsed16
Abstract: This study was conducted in 1985 by Ecology's Water Quality
Investigations Section in response to results from the Basic Water
Monitoring Program (BWMP) which showed higher levels of DDT and
metabolites DDE and DDD in Yakima River fish than elsewhere in
Washington State between 1979 and 1984. The study's objective was to
evaluate the hazards to human health and aquatic life, identify
sources and ... determine if contamination was primarily due to recent
illegal use or historical applications (Johnson et al. 1986). Fish,
water, and bed sediments were analyzed. Sediment samples were
collected from the Yakima main stem and from tributaries considered to
have greatest potential for DDT contamination. These data were also
summarized and reported in a journal publication (Johnson et al. 1988).
The area of study was the Columbia River Basin, Yakima River.
Each sediment sample was homogenized by stirring with stainless-steel
spoons, stored in containers, immediately placed on ice, and shipped
to the laboratory.
Target analytes were organochlorine pesticides, Aroclor PCBs, and Hg were
the target analytes, but only the frequently detected organochlorine
compounds were reported. Mercury was detected in all samples.
Therefore, the database contains only p,p'-DDT, -DDE, -DDD and
o,p'-DDT results. Results for dieldrin, endosulfan, aldrin, Aroclor
PCBs, and mercury are also included. Conventional analyses included
sediment grain size, percent dry weight and total organic carbon content.
Analytical techniques included organochlorine pesticides and PCBs (EPA
608, additional information on analysis is provided in Appendix II of
the document); Mercury (EPA 245.2 with modifications). All results
are reported on dry weight basis. Total DDT concentrations reported
are based on the sum of detected concentrations of o,p'- and p,p'-DDT,
DDE, and DDD compounds.
The information for this metadata was taken from the Columbia River
Basin: Sediment Database Abstracts.
