Ecological risk assessment of a decommissioned military base
Abstract
The ecological health risks to selected terrestrial animals at a decommissioned military base in Atlantic Canada have been assessed. Areas of the base varied in terms of terrain, ground cover, as well as types and extent of contamination, dependent on former uses of the sites. Analysis of surficial soils, sediments, water and fish tissue at the base indicated contamination by metals, PCBs, and various petroleum products and their constituents. Identification of chemicals of concern was based on these analyses, in conjunction with detailed chemical selection procedures. Exposures to chemicals of concern for ecological receptors were assessed in one of two ways. The exposures of moose, snowshoe hare and meadow vole were estimated in areas with surficial contamination, based on expected exposures to environmental media via oral inhalation, and dermal routes of exposure. For two top predators (mink and bald-headed eagle), exposures to bioaccumulative chemicals (cadmium, lead, mercury and PCBs) via transport through the aquatic and/or terrestrial foodchain were estimated. A toxicological assessment was conducted for the chemicals of concern, to yield exposure limits derived from governmental regulations or developed based on no-observed-effect-levels (NOELs) reported in scientifically sound toxicological assays in relevant species. The risk evaluation of each chemical of concernmore »
