Abstract
The presence of heavy metals in the environment can be detrimental to a variety of living species including human. River crabs are sensitive to heavy metals .The concentrations of cadmium, copper, lead and zinc were analyzed in muscles, hepatopancreas, gills and exoskeletons using ICP-MS . Zinc was greater in muscles and hepatopancreas, whereas copper was greater in muscles and gills. Cadmium and lead were within the range of limits for hazardous substance about the pollution-free food. Then river crab can be an effective bioindicator for assessing metal levels in environment.
