An Assessment of Metals Contamination in Lake Roosevelt.Entry ID: BESTsed15
Abstract: In response to reports of elevated metals concentrations in fish and
other environmental samples from Lake Roosevelt, Ecology conducted a
series of field surveys between May and September 1986 to determine
the extent and significance of contamination (Johnson et al. 1988).
Sediment, water samples and a variety of fish species were used in
this assessment. These data were also summarized in a ... journal article
(Johnson et al. 1990).
The area of study was Columbia River (Lake Roosevelt, Canadian
Border-Lower Arrow Lake). Stations sampled were in the Lake Roosevelt
area: collected as a series of grabs in a longitudinal transect from
the international border to Grand Coulee Dam; collected at the mouths
of the Colville, Kettle, Spokane and Sanpoil Rivers.
Sample containers were glass jars with teflon lids and were stored on
ice prior to shipping to the laboratory.
Target analytes were Metals (Zn, Cu, Pb, As, Cd, Hg).
Analytical techniques included: Zn (EPA 289.2); Cu (EPA 220.2); Pb
(EPA 239.2); As (EPA 206.2); Cd (EPA 213.2) and Hg (in-house). All
data are reported on a dry weight basis.
The information for this metadata was taken from the Columbia River
Basin: Sediment Database Abstracts.
