A recent manuscript on contamination of Atlantic spotted dolphins in
Western South Atlantic is available:
Leonel, J.; Taniguchi, S.; Sasaki, D.K.; Cascaes, M.J.; Dias, P.S.; Botta,
S.; Santos, M.C. de O. & Montone, R.C. 2012. Contamination by chlorinated
pesticides, PCBs and PBDEs in Atlantic spotted dolphin (Stenella frontalis)
in western South Atlantic. Chemosphere, 86: 741-746.
Abstract: Chlorinated pesticides, PCBs and PBDEs were analysed in nine
blubber samples of Atlantic spotted dolphins, Stenella frontalis,
incidentally captured during fishing operations in southern and
southeastern Brazil between 2005 and 2007. The majority of compounds
analysed were detected, suggesting widespread contamination over the
region. Although the samples came from a location far from main coastal
industrial areas, the results revealed an influence from such sources.
Therefore, levels of PCBs (774–23659 ng g-1 lipid wt.) and PBDEs (23–1326
ng g-1 lipid wt.) detected seem to be related to the movement of
individuals throughout near-shore and offshore waters. The sample from a
lactating female exhibited a lower level of contamination and a distinct
pattern, indicating selective transfer favouring less lipophilic compounds.
