CADMIUM ACCUMULATION BY INVERTEBRATES LIVING AT THE SEDIMENT-WATER INTERFACE

Macroinvertebrate contamination at sediment-water interface. Composition, densities and cadmium concentrations of invertebrates ; relation to vertical profiles of cadmium treatment levels of overlaying water and sediment taken in Lake Laflamme (Canada) ; temporal changes in cadmium accumulation of insects collected in autumn and spring. Experimental protocol described.
