AB  - Organic compounds, in particular organochlorines, are highly persistent compounds 
      which accumulate in biotic and abiotic substrates. Marine mammals bioaccumulate 
      and biomagnify persistent organic pollutants (POPs) through diet.  summation operatorPCB (26 PCB 
      congeners),  summation operatorDDT (pp-DDT, pp-DDD, pp-DDE),  summation operatorHCH (alpha-HCH, beta-HCH, gamma-HCH, delta-HCH), HCB 
      and mirex were analyzed from samples of subcutaneous adipose tissue of common 
      dolphins, Delphinus delphis, and Fraser's dolphins, Lagenodelphis hosei, obtained 
      in 1999 and 2012. The aim of this study was to determine the concentrations of 
      POPs to get baseline information on the current state of pollution by these 
      compounds in these two species in South Atlantic. At the same time, to assess 
      concentrations of POPs in relation to age, the total length and sexual maturity 
      in common dolphins. Organochlorine pesticides dominated Fraser's dolphins, DDT 
      being the most abundant, while PCBs were mostly present in common dolphins. In 
      both species, the distributions of isomers or metabolites followed the order: 
      beta-HCH>delta-HCH>gamma-HCH>alpha-HCH and pp-DDE>pp-DDD>pp-DDT. As for  summation operatorPCB, the largest 
      contribution was given by congeners of high molecular weight, particularly by 
      hexa and hepta - CBs. Common dolphins did not show effects on sexual maturity, 
      age and standard length in the concentration of organochlorines. The mean 
      concentrations found in this study are lower compared to those reported in other 
      studies performed in dolphins elsewhere. This study provides new information 
      regarding levels of organochlorines in common dolphins for the Southwestern 
      Atlantic.
