Abstract
The aim of this study was to evaluate Cd and Pb concentrations in the hepatopancreas, gills, muscle
tissue and carapace of the crab Callinectes sapidus and in sediments from the mouth of the river
Segura (SE Spain), an area that has undergone great anthropogenic change in recent decades. Lead
concentrations were higher than Cd concentrations in the hepatopancreas, gills and muscles; no
statistical differences were found between the sexes. Cadmium and Pb concentrations in sediments
did not exceed the probable effect level in guidelines for the protection of aquatic life. The Biological
Sediments Accumulation Factor (BSAF) was higher for Cd than Pb in the hepatopancreas, gills and
carapace. For Cd, the hepatopancreas had the highest BSAF of all tissues, followed by gills. As well, the
hepatopancreas had the highest Individual Mean Bioaccumulation Index (IMBI). The hepatopancreas
and gills of the blue crab could thus be useful tissues for practical field monitoring of metal
contamination in this ecosystem
