Dear Marmamers: The following manuscript (with abstract attached) was recently published. PDf requests with Dr. Marcos Santos (sotalia@gmail.com). Yogui, G.T.; Santos, M.C. de O.; Bertozzi, C.P. & Montone, R.C. 2010. Levels of persistent organic pollutants and residual pattern of DDTs in small cetaceans from the coast of Sao Paulo, Brazil. Marine Pollution Bulletin, 60: 1862-1867. The state of Sao Paulo is the most developed area in Brazil and was impacted by persistent organic pollutants for several decades. This study investigated organochlorines in five species of small cetaceans (Pontoporia blainvillei, Stenella frontalis, Sotalia guianensis, Tursiops truncatus and Steno bredanensis) found dead along the coast of Sao Paulo between 1997 and 2003. DDTs (15.9 µg -1 lipid; mean for all pooled individuals) and PCBs (8.08 µg -1) exhibited the highest concentrations in the animals, reflecting large amounts formerly used in Brazil. Lower levels of mirex 0.149 µg -1), HCB (0,051 µg -1), CHLs (0.008 µg -1) and HCHs (0.007 µg -1) were detected in all species. Residual patterns of DDTs in dolphins suggests that o,p’-DDT is more recalcitrant than p,p’-DDT in the body of the animals and/or the environment. In contrast to p,p’-DDT, residues of o-p’-DDT seem to be preferentially converted into o,p’-DDD rather than o,p’-DDE. -- Dr. Marcos Cesar de Oliveira Santos Projeto Atlantis, Laboratorio de Biologia da Conservacao de Cetaceos PROGRAMA JOVEM PESQUISADOR EM CENTROS EMERGENTES- FAPESP Programa de Pos-Graduação em Zoologia, Departamento de Zoologia, Instituto de Biociencias, Universidade Estadual Paulista "Julio de Mesquita Filho" (UNESP), Campus Rio Claro
