This book was released on 1995 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1996 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic fauna of northern Alberta rivers are exposed to contaminants from municipal and industrial sources, including pulp mills. Studies of sub-lethal effects such as increased levels of enzyme activity can indicate an early response to environmental stress in these fauna. This paper reports on a project conducted to examine mixed function oxygenase activity in fish collected from six sites on the upper Athabasca River, upstream and downstream from the Hinton bleached kraft mill. The investigators applied two enzyme assays to fish liver samples collected from mountain whitefish, longnose sucker, northern pike, and white sucker. Enzyme activities were compared with contaminant residue levels and sex steroid hormones reported for the same fish in other related studies. Results presented compare levels of chlorinated dioxin and furan residues in the fish with the site-by-site pattern of enzyme activity.

Book excerpt: 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 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.

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.

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.

This book was released on 1997 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

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.

This book was released on 1996 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vitamin A (retinoids) and E (tocopherol) have received increasing attention as possible indicators of exposure to a variety of environmental pollutants. This study examines vitamin A and E indices in fish collected from northern Alberta rivers, where fish are exposed to a variety of industrial effluents, as part of a multi-faceted study into altered fish physiological function due to environmental contaminants. The fish species targeted for collection were burbot, northern pike, and longnose sucker. The investigators conducted biochemical analyses in the laboratory to determine levels of retinol, dehydroretinol, retinyl palmitate (three storage forms of vitamin A), beta carotene (precursor form of vitamin A), and tocopherol in fish livers. For comparison, results are organised into reference (upstream locations and tributaries receiving no input from pulp mills), near-field (within 100 kilometres downstream from a pulp mill source), and far-field (over 100 kilometres downstream) groups, where sample sizes were adequate.
