Persistent organic pollutants in juvenile Magellan penguins (Spheniscus magellanicus) found on the northern shore of the state of São Paulo and southern shore of the state of Rio de Janeiro, Brazil.

Abstract：

:In the present study, persistent organic pollutants (POPs) were determined in 25 livers from Magellanic penguins, Spheniscus magellanicus, found on the state of São Paulo and Rio de Janeiro (Brazil). The following concentrations of POPs (wet weight) were found: ∑ PCBs: 18.9-775.8 ng g(-1); ∑ DDTs: 2.3-275 ng g(-1); and ∑ HCHs: 1.0-11.8 ng g(-1). Among the PCBs, there was a predominance of hexachlorobiphenyls (138 and 153) and heptachlorobiphenyls (180 and 187). Among the organochlorines, DDT predominated. Through histopathologic exams a positive correlation was found between HCB and cardiovascular failure (p=0.012), as HCB values (wet weight) were 6.33-96.49 ng g(-1) for positive animals and 2.45-19.63 ng g(-1) for negative animals. Studies on POPs in Magellan penguins contribute to a better understanding of the distribution and trends of these pollutants in the western South Atlantic Ocean.
