; ;

Earthworms are often utilized in the management and treatment of sludges. A study was conducted to determine earthworm bioaccumulation of heavy metals present in some sludges. Experimental methods and materials used are described. Conversion of activated sludge into egesta by the earthworm Eisenia foetida resulted in neither an increase nor a decrease of extractable cadmium, copper, nickel, zinc, or lead. Bioaccumulations ranged from 8-250 ppm. (7 graphs, 18 references, 4 tables)
