Persistent organic pollutants (PCBs, PBDEs and organochlorine pesticides) in Brazilian sharpnose shark (Rhizoprionodon lalandii) liver from Ubatuba coast, São Paulo, Brazil. Marine Pollution Bulletin., v. 86, p. 591-593, 2014.

In the present study, persistent organic pollutants (POPs) were determined in 14 livers from specimens of the Brazilian sharpnose shark (Rhizoprionodon lalandii), which is an important economic resource for small-scale fisheries on the southeastern coast of Brazil. The following concentrations (lipid weight) of POPs were found: ∑PCBs: 1019 ± 267 ng g-1; ∑DDTs: 111 ± 40 ng g-1and ∑PBDEs: 10.4 ± 4.78. PCB153 made the greatest contribution to∑PCB (21.4%), followed by PCB 138 (14.6%) and PCB 180 (9.94%). Among chlorinated pesticides, only the p,p’-DDE and p,p’-DDD isomers had concentrations above the detection limit. Moreover, levels above the detection limit were found only for PBDE congeners 47 and 100 (BDEs 47 > 99). On average, BDE 47 accounted for 88% of the total PBDE load. The feeding habits of the Brazilian sharpnose shark close to the Brazilian coastline are likely the most important difference regarding the accumulation of POPs in comparison to oceanic species that feed in deeper waters. Thus, this species may be used to evaluate the pollution of coastal areas as well as human exposure to contaminants, as the Brazilian sharpnose shark is a frequently used for human consumption. Further studies in other areas of Brazil and involving other species are needed to clarify the mechanisms and potential impact of POPs, which can affect the biology of different organisms and cause population  declines.
