Trace Metal Residues in Swimming Warrior Crab Callinectes bellicosus: A Consumption Risk

This study was carried out in the Navachiste coastal lagoon, Mexico, surrounded by intensive agricultural and aquaculture activities that cause environmental pollution by the deposition of trace metal residues in the sediments of this coastal lagoon. The trace metals are bioaccumulated by benthic or...
