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.
A Database of Environmental Samples Collected and Analysed for the Northern River Basins Study

ISBN:
Category : Nature
Languages : en
Pages : 120
Book Description
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 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.
Analysis for Liver Mixed Function Oxidase in Fish, Upper Athabasca River, 1992

Book Description
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.

Accumulation of Fish Mixed Function Oxygenase Inducers by Semipermeable Membrane Devices in River Water and Effluents, Athabasca River, August and September, 1994
Author: Joanne Louise ParrottPublisher:
ISBN:
Category : Effluent quality
Languages : en
Pages : 54
Book Description
Reports on a study that used semipermeable membrane devices (SPMDs) to identify industrial effluents along the Athabasca River system that induce mixed function oxygenase (MFO) activity in fish cell lines. These SPMDs provided samples of known exposure time in effluents and river waters by simultaneously sampling the effluent stream and the river upstream and downstream of the mixing zone at each site. The investigators deployed the SPMDs for two weeks at one major town and five industrial wastewater sites (four pulp mills and one oil sands facility) on the Athabasca, and at one pulp mill on the Lesser Slave River. They tested SPMD extracts for MFO activity using cell culture techniques in top minnow (Poeciliopsis lucida) hepatoma cells. Results presented include comparisons of MFO induction potency between different sampling sites and between type of effluent source.
