Spatial Trends in TCDD/TCDF Concentrations in Sediment and Bottom Fish Collected in Lake Roosevelt (Columbia River).Entry ID: BESTsed13
Abstract: In June 1990, as part of Ecology's investigation of contaminants in
Lake Roosevelt, a series of sediment and bottom fish samples were
collected from Lake Roosevelt and vicinity for analysis of PCDDs and
PCDFs (Johnson et al. 1991a). The objective of the survey was to
evaluate the transport and distribution of these compounds throughout
the lake. The sediments and bottom fish collected during this ... effort
were also analyzed for additional xenobiotic compounds. These data
are reported in Johnson (1991). Other Ecology reports describe
results from analysis of Lake Roosevelt sportfish and suspended matter
samples for dioxins and furans (Johnson et al. 1991b,c).
The area of study was Columbia River (Lake Roosevelt, Rufus Woods
Lake) and Long Lake (Spokane River). Six stations were sampled in Lake
Roosevelt, one in the Spokane River (Long Lake) and one in Rufus Woods
Each sediment sample consisted of a composite of three grab samples.
Surface sediment samples (top 2 cm) were transferred to
stainless-steel beakers and homogenized by stirring with
stainless-steel spoons. Samples were stored on ice in the field.
Target analytes were Fifteen 2,3,7,8-substituted PCDDs and
PCDFs. Octachlorodibenzodioxin and octachlorodibenzofuran were not
reported. Conventional analyses included sediment grain size and total
organic carbon content.
Analtyical techniques included the following. PCDD/PCDF analysis
followed methods described in EPA (1990) and EPA et al. (1990) and was
performed by the EPA Environmental Research Laboratory in Duluth, MN.
All data are reported on a dry weight basis.
The information for this metadata was taken from the Columbia River
Basin: Sediment Database Abstracts.

Quality EPA Duluth Laboratory (U.S. EPA 1990; U.S. EPA et al. 1990). All data
included in this report passed EPA's quality assurance criteria.
Duplicate samples were submitted to assess the precision of the
analysis. Close agreement was reached between duplicate sample
... The laboratory data were reviewed and data qualifiers were added as
appropriate. However, the only data qualifier that could be defined
was "U" - Not detected. Value is the detection limit. The other
qualifier codes: QR, QR18, QR32, and QR89 indicated data that were
unusable. Analyses with these qualifier codes were reported by the
Environmental Research Laboratory in Duluth, MN.
Data used for this report were from the lab data sheets provided in
the appendix of the report. Fish and sediment sample analysis results
as a function of river miles below the Canadian border (a large pulp
and paper mill is located north of the border in Castlegar, BC) were
compared for assessment of spatial trends.
All data entered in the database were reviewed for data entry errors.
All detected errors were corrected.
