| Short Description |
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 polychlorinated dibenzo-p-dioxins (PCDDs) and -dibenzofurans (PCDFs). The objective of this survey was to evaluate the transport and distribution of these compounds through the lake. (Also see abstract below) | |||

| Abstract | Long Description |
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 polychlorinated dibenzo-p-dioxins (PCDDs) and -dibenzofurans (PCDFs). The objective of this survey was to evaluate the transport and distribution of these compounds through the lake. The source of PCDDs and PCDFs is the Celgar bleached kraft pulp mill in Castlegar, B.C., approximately 30 miles above the international border. Celgar was established in the early 1960s and does not have effluent treatment. Previous Ecology reports describe results from analysis of Lake Roosevelt sportfish and suspended matter samples (Johnson et al., 1991a,b). Background information on PCDDs/PCDFs and the Celgar issue can be found in the sportfish report. Analytical support for the present study was provided by EPA. |
