520 |a"As part of the work to examine the impact of development on ecosystem health and integrity on the Peace and Athabasca river basins in Alberta, the Northern River Basin Study (NRBS) was required to determine “the contents and nature of the contaminants entering the system ... particular reference to water, sediments and biota" and to determine “... the current concentration of contaminants in water and edible fish tissue and how are these levels changing through time and by location". The Reach Specific Study (RSS) was designed to measure spatial and temporal trends of contaminants including polychlorinated dibenzo-p-dioxins and -dibenzofurans (PCDD/Fs) in sediment, water and and biota (fish and invertebrate) samples collected at six locations on the upper Athabasca River downstream of Hinton (AB) in spring 1992, fall 1992 and spring 1993. The General Fish Collection (spring 1992), the Long nose sucker and Northern pike liver study (fall 1994) and the Special Burbot Collection (fall 1992 and 1994), and the Ft. Chipewyan winter fishery study (1994/95) were also conducted to examine levels in fish tissues within the Athabasca, Peace and Slave River basins. The purpose of this report is to summarize the levels of PCDDs and PCDFs in fish from these various studies and to assess temporal trends of 2,3,7,8-TCDD and 2,3,7,8-TCDF by comparison with previously published data. A second objective was to reexamine pathways of accumulation of 2,3,7,8-TCDD and 2,3,7,8-TCDF from water and suspended sediment to fish, first measured in the upper Athabasca River in 1992 (Pastershank and Muir 1995)"--Report summary.
