Book Description
The Northern River Basins Study was established to examine the relationship between industrial, municipal, agricultural and other developments and the Peace, Athabasca and Slave River basins. Over 4 1/2 years about 150 projects or 'mini studies' were contracted by the Study under eight component categories including contaminats, drinking water, nutrients, traditional knowledge, hydrology / hydraulics, synthesis and modelling, food chain and other river uses.

Book Description
Presents a study that collected and prepared fish from 23 sites along the Peace, Athabasca, and Slave river drainages in order to conduct physical, physiological, contaminant, and biophysical analyses. The primary fish species targeted for collection and analysis was burbot, used as a sentinel species for monitoring contaminants in northern waters because of its wide distribution, ease of catching, place at the top of the aquatic food chain, and large liver which can bioaccumulate organic compounds. Other species collected were northern pike, longnose sucker, and flathead chub. Specific analyses included gross pathology, metals, liver mixed function oxygenase induction, sex steroids and gonad morphology, retinols, metallothioneins, and basic life history information. Fish were also examined externally and internally for gross pathological abnormalities and deformities. Appendices contain descriptions of fish collection and handling protocols, as well as detailed data.

Book Description
Metallothioneins are a family of proteins whose synthesis in animal organs and tissues can be induced by exposure to heavy metals. This report describes metallothionein concentrations in fish collected from northern Alberta rivers and tributaries. The analyses incorporate results from examination of kidney, liver, intestine, and gill tissues of burbot, longnose sucker, northern pike, and flathead chub. Results are organised into reference (upstream locations and tributaries receiving no inputs from pulp mills), near-field (within 100 kilometres downstream from a pulp mill), and far-field (over 100 kilometres downstream).

Book Description
Summarises and interprets the analytical results for various organic chlorine contaminants in fish collected from northern Alberta river systems and also compares the observed organochlorine levels with the regulatory limits set by Health Canada. Major organochlorine groups detected were polychlorinated biphenyls, DDT- and chlordane-related compounds, toxaphene, and chlorinated phenolics. Background information is included on the properties, uses, toxicity, sources, environmental fate and transport, and bioaccumulation of the contaminants studied. Results are given for such fish species as mountain whitefish, burbot, northern pike, and longnose sucker, and for concentrations observed at locations downstream and upstream of known sources of contaminants.

Book Description
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 Description
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).

Book Description
AWARDS:2006 Outstanding Academic Title, by CHOICEThe 2005 Award for Excellence in Professional and Scholarly Publishing by the Association of American Publishers (AAP) Best Reference 2005, by the Library JournalRivers of North America is an important reference for scientists, ecologists, and students studying rivers and their ecosystems. It brings together information from several regional specialists on the major river basins of North America, presented in a large-format, full-color book. The introduction covers general aspects of geology, hydrology, ecology and human impacts on rivers. This is followed by 22 chapters on the major river basins. Each chapter begins with a full-page color photograph and includes several additional photographs within the text. These chapters feature three to five rivers of the basin/region, and cover several other rivers with one-page summaries. Rivers selected for coverage include the largest, the most natural, and the most affected by human impact. This one-of-a-kind resource is professionally illustrated with maps and color photographs of the key river basins. Readers can compare one river system to another in terms of its physiography, hydrology, ecology, biodiversity, and human impacts.* Extensive treatment provides a single source of information for North America's major rivers* Regional specialists provide authoritative information on more than 200 rivers* Full-color photographs and topographical maps demonstrate the beauty, major features, and uniqueness of each river system* One-page summaries help readers quickly find key statistics and make comparisons among rivers

Book Description
Presents the findings of various field and laboratory projects that studied fish distribution, movement, habitat utilization, and gross pathology in the northern Alberta river basins. Begins with a description of the river basins and related water bodies, a list of fish species found, and an overview of fish distribution and relative abundance in the mainstem rivers. This is followed by a synthesis of available information on movements of fish through space and time, as collected from fish tagging and radio telemetry studies. Movements of individual fish are also described (spawning movements and movements to summer feeding and winter habitats). Finally, critical fish habitats (spawning, feeding, and overwintering) are noted, food chain studies are summarized, and responses of fish to changes in water quality (including pathological manifestations) are reviewed.

Book Description
The NTBS was designed to address the ecological concerns about pulp mill expansion, and to increase scientific knowledge about environmental conditions [ecology, ecosystem sustainability, water pollution and control, habitat, effect on fish and fishing, etc.] in the major river systems of the north. The study's objectives were to gather and interpret sound scientific information about the basins, develop appropriate recommendations for basin management, and communicate effectively with the public. The government response report confirms the governments' commitment to ecosystem sustainability and to pollution control in northern rivers. First Nations and Metis aboriginal [native] peoples contributed significantly to the NRBS.
