PCBs, PBDEs and organochlorine pesticides in crabs Hepatus pudibundus and Callinectes danae from Santos Bay, State of Sao Paulo, Brazil

The occurrence of persistent organic pollutants (POPS) as polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and polybrominated diphenyl ethers (PBDE) in crabs Hepatus pudibundus and Callinectes danae was assessed from two different places inside of the Santos Bay and Moela Island near one of the most economically important metropolitan areas in Southern Brazil. Among POPs analyzed, Sigma PCBs (222-923 ng g(-1) lipid weight) and Sigma DDTs (154-410 ng g(-1) lw) exhibited the highest concentrations in the crabs. Sigma HCHs ranged from 10.3 to 30.9 ng g(-1), lw and were found in all individuals. Other OCPs found in lower concentration was Mirex (7.6-41.6 ng g(-1) lw) and HCB (5.83-16.9 ng g(-1) lw). Sigma PBDEs (24.1 ng g(-1) lw) were only found in one male individual from the species C. danae collected near to the submarine sewage of Santos. Male crabs showed higher POP concentrations than female crabs for those two species. (C) 2011 Elsevier Ltd.
