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.
