    dct:description "The data set consisted of data from 13 locations in Lake Roosevelt and 3 in Rufus Woods Lake. The impetus for this survey was the detection by Environment Canada and the British Columbia Ministry of Environment, of contaminated lake whitefish and mountain whitefish below Celgar bleached kraft pulp mill in Castlegar, B.C., about 30 river miles upstream of Lake Roosevelt. The contaminants of concern included 2,3,7,8-TCDD and 2,3,7,8-TCDF. The data set was designed to obtain an accurate estimate of mean TCDD and TCDF concentrations in muscle tissue of major sportfish species from popular fishing areas. The survey also included analysis of limited fish samples from Rufus Woods Lake, the Columbia River reservoir below Lake Roosevelt, and Long Lake, the lower reach of the Spokane River." ;
