摘要
Due to their efficient filtration capabilities, zebra mussels (Dreissena polymorpha) are effective bio-monitors of a wide range of environmental pollutants. In this study we test the suitability of zebra mussels as bio-monitors of Sr-90 contamination around a nuclear power station situated at Gentilly, Quebec along the St. Lawrence River. Based on the latest emission data which indicated negligible contributions of Sr-90 to the river, we hypothesize that dreissenids collected at sites upstream (Montreal), at the station and downstream from the station (Donnacona) would show no significant differences in shell concentrations of Sr-90. Zebra mussel shell concentrations of Sr-90 were in the order of 0.02 pCi/g at Gentilly, 0.04 pCi/g at Montreal and 0.03 pCi/g at Donnacona, all values being below the limit of detection of the analytical method. We also considered the implication of Sr-90 contamination to higher trophic levels in the food chain.
