Metal contamination in the sediment, pondweed, and snails of a stream receiving effluent from a lead/zinc mine in southern China.
This study assessed the potential of Potamogeton crispus and Pomacea canaliculata as biomonitors of sedimentary metal contamination. The results indicate P. crispus possesses several attributes of a biomonitor and its tissue concentrations of Cd, Pb and Zn may reflect the levels of sedimentary contamination by these metals. Although P. canaliculata can accumulate metals to high levels and serve as an indicator of metal contamination, its tissue metal concentrations did not correlate with those of the sediments or macrophytes.
