Edmonton - Alberta : Northern River Basins Study 1995. 56p. in various pagings. : graphs, references, tables ; 28 cm. Northern River Basins Study project report 1192-3571 No. 59 "This project was designed to test the toxicity of depositional sediments from the upper Athabasca River using freshwater benthic invertebrates in chronic exposure studies under laboratory conditions. Additional analyses were performed on the in situ benthic invertebrate community structure to describe species distribution and abundance. Information from these tests will be used to determine cumulative effects of the Hinton combined effluent by comparing upstream and downstream sites."-Study perspective.
