520 |a"For the majority of vertebrate species, a variety of important physiological processes depend upon adequate levels of vitamin A (retinoids) and vitamin E (tocopherol). Fish obtain much of their vitamin A and E directly from their diet, and under normal physiological conditions most vitamin A compounds are stored in the liver. These compounds have received increasing attention from scientists as possible indicators of exposure to a variety of environmental pollutants. Exposure to some environmental contaminants (e.g., PCBs, dioxins and furans) can alter vitamin A metabolism in both mammals and fish. The aquatic fauna of northern rivers in Alberta are exposed to pulp mill effluent, and other types of industrial and municipal effluents. A bench mark program was seen as the first step in assessing the utility of detecting possible pollutant effects by measuring vitamin stores in fish. The objective of this project was to examine vitamin A and E indices in fish collected from the Peace, Athabasca and Slave rivers and their major tributaries in 1994, part of a multi-faceted study into altered fish physiological function as a result of environmental contaminants"--Study perspective.
