"June 1995." Includes bibliographical references. "The following report summarizes the results from the toxicological testing of depositional sediments in the upper Athabasca River using freshwater benthic invertebrates in chronic exposure studies under laboratory conditions as well as analyses of the in situ benthic invertebrate community structure. Sediments were collected at one or two sites upstream from Hinton (one control at site ARC in May 1993 and two controls at sites ARC and ARC2 in September 1993) and at five to six sites at varying distances downstream from Hinton on the same dates in the spring and fall"--Report summary.
