Assessing pulp mill contamination using morphological deformities in chironomid larvae (Diptera chironomidae) : upper Athabasca River, April 1992 / by W. F. Warwick. Edmonton - Alberta : Northern River Basins Study 1996. vi, 18p. : figs., graphs, references ; 28 cm. Northern River Basins Study project report 1192-3571 No. 140 "The goal of this project was to provide baseline information on the occurrence and spatial distribution of chironomid deformities in depositional areas of the upper Athabasca River. These data were supplemented by identification and counts of individual chironomid taxa. The technique allowed an evaluation of spatial trends in the incidence of deformities relative to known point source effluents in the upper Athabasca River."--Study perspective.
