This book was released on 1996 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents the analytical results and spatial trends for the following contaminants in bottom sediment samples collected from northern Alberta rivers in 1994-95: polychlorinated dibenzo-p-dioxins, dibenzofurans, resin acids, polyaromatic hydrocarbons, chlorinated phenolics, polychlorinated biphenyls, extractable organic halides, toxaphene, and mercury. Sampling locations were chosen to provide broad coverage of both the Athabasca and Peace river basins, coverage of key mixing zones downstream from four pulp mills, and replication with locations sampled previously. The 1994-95 survey objectives included: determination of within-site variability in bottom sediment contamination; testing of the assumption that the sand fraction is not an important repository of contaminants; and providing a data set for comparison with earlier bottom sediment collections in 1988-89 and 1992.

Book excerpt: Presents results of contaminant analyses of bottom sediments collected from the Peace and Athabasca river basins 1988-90 and 1992. Contaminant groups represented are the polychlorinated dibenzo-p-dioxins and dibenzofurans, resin acids, chlorophenolic compounds, and polycyclic aromatic hydrocarbons. Contaminant concentrations were correlated with percent organic carbon of the fine fraction (the fraction on which analysis was performed. Correlations between concentrations of bleached kraft mill related contaminants were also investigated and results are presented.

Book excerpt: An important component of the Northern River Basins Study was the original data resulting from the collection and analysis of environmental samples. Samples were collected, stored, and analysed by a number of different agencies, and an inventory of samples obtained by the Study and results data were compiled into a single electronic database to ensure future ease of access to the original data. This report describes the data contained in the database, the methods used to compile the database, the media and the nature of the samples, the collection site, and the data collected. Information is provided on which analyses were conducted on samples as well as the values of various parameters measured for the samples. All the files and the data fields that comprise the database are described in the users' guide in the report appendix.

Book excerpt: Report to the federal ministers of Environment and Indian & Northern Affairs, Alberta's Minister of Environmental Protection, and NWT's Minister of Renewable Resources. Summarises the main scientific findings of the Northern River Basins Study, which was established to examine the relationship between industrial, municipal, agricultural, and other development and the Peace, Athabasca, and Slave River basins. Reviews the characteristics of the northern river basins and their peoples, the organisation of the Study, and major findings in the areas of environmental overview, use of aquatic resources, traditional knowledge, flow regulation, fish distribution and habitat, nutrients, dissolved oxygen, contaminants, drinking water, ecosystem health, modelling, human health, and cumulative effects. Recommendations by the Study Board, First Nations, and scientific advisors regarding such issues as basin management, monitoring, research, public participation, and a successor organisation are then presented. Also includes a summary of opinions, suggestions, and recommendations expressed at 17 community workshops held throughout the northern river basins area.

Book excerpt: Describes field and analytical methods, and presents results, from a reach-specific study of 200 kilometres of the Athabasca River between Hinton and Whitecourt. This section of the river receives municipal effluent from Hinton in addition to pulp mill effluent. Results are presented for water, suspended sediment, and bottom sediment samples collected in 1992. Contaminants studied include dioxins, furans, chlorinated phenolics, resin acids, organochlorine pesticides, and metals. The data presented will be incorporated into a synthesis report addressing the distribution of contaminants within northern Alberta rivers.

This book was released on 1997 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines the mechanisms of natural riverine sediment production in the Northern River Basins Study area, together with the routine data for suspended sediment in the area's rivers, as background for the examination of sediment-associated contaminants. Topics examined include: the causative mechanisms and boundary conditions affecting the sediment regime, including area topography, geology, and hydrology; availability and adequacy of data on suspended sediments in the area; time trends of fluvial suspended sediment dynamics on a seasonal (open water and ice regime) and annual basis, over the long term, and in critical events; sediment sources, pathways, and fates, and sediment dynamics at basin-wide, reach, and site levels; sediment quality, including sediment-associated characteristics of pulp mill effluents and sediment-contaminant relationships; and implications for sediment-associated contaminants. Recommendations are made for monitoring and assessment of the sediment component of the area's ecosystem.

Book excerpt: The objectives of this project were to re-examine sediment toxicity at sites sampled previously on the Athabasca River, including sites in the oil sands area, and to conduct toxicity testing on a number of additional sites on the Athabasca, Smoky, and Peace rivers. Investigators tested suspended and bottom sediment samples using four species of freshwater benthic invertebrates in chronic exposure studies. Endpoints measured included survival, growth (amphipod, chironomid, and mayfly) and reproduction (oligochaete worm). Test results were compared with those using standard reference sediment samples for biological quality assurance.

Book excerpt: This assessment documents the current status of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in Canada's aquatic environment, based largely on scientific supporting documents to the Canadian Environmental Quality Guidelines & with updated information & data wherever available. Chapters cover the following topics: physico-chemicals properties of PCDD/Fs and their mode of toxic action; sources (natural & anthropogenic) & releases of PCDD/Fs to the Canadian environment; fate & behaviour of PCDD/Fs in aquatic systems & biota; Canadian environmental levels of PCDD/Fs in air, water, sediment, & aquatic organisms; toxic effects of PCDD/Fs observed in aquatic & semi-aquatic organisms (including water-, sediment-, & dietary-based toxicity), and the initiatives under way to manage PCDD/Fs in the Canadian environment as well as best management practices. The final section discusses emerging issues such as recent advances in waste incineration, PCDD/F treatment in the pulp & paper industry, and use of biological screening in toxicity determination.

Available in PDF, EPUB and Kindle. Book excerpt: This report provides an interpretation of analytical results for dioxins and furans in water, biofilm, sediment, invertebrates, and fish samples collected on the Athabasca and Peace Rivers in 1992. The analysis focused on the partitioning, fate, and bioaccumulation of the two compounds having the greatest potential to accumulate in animal tissue, namely 2,3,7,8-tetrachloro dibenzo-p-dioxin and 2,3,7,8-tetrachloro dibenzofuran, in order to assist in the assessment of ecosystem health and long-term effects. The report compares the levels of these compounds found upstream and downstream from pulp and paper mills, and compares the detected levels to the limits recommended under the Canadian Environmental Quality Guidelines (for sediment and water) and Health Canada guidelines (for fish tissue).

Available in PDF, EPUB and Kindle. Book excerpt: Describes and presents simulation results using a revised model simulating the fate of contaminants in the Athabasca River. The revised fate model allows predictive sediment transport simulation within the WASP4 model framework, predicts resuspension from hydraulic information supplied by WASP4 and from user-supplied sediment characteristics, and can be applied to different flow conditions without having to re-describe sediment transport rates. Several simulations were run using input files from the original model calibration. Program listings of subroutines are included.
