“…The higher values in the latter samples confirm the fact that PBDEs, like most other persistent organic pollutants, are found at higher concentrations in environmental matrices collected near industrial or highly populated centers (Lebeuf et al, 2004). Alonso et al (2012) analyzed liver samples of franciscana from different regions of Brazil and found similar concentrations in samples from the FMA III, but lower values than those reported in the present study in the samples from the FMA II. This evaluation should be considered with caution, since there are difficulties associated to comparison between different organs.…”

“…The concerns generated by the DRC contamination are amplified when it is taken into account that these cetaceans are exposed to other persistent bioaccumulative toxicants (PBTs) that have been shown to be endocrine disrupters, tumor promoters and immunosuppressors as well (Schecter et al, 2006;Simonyte et al, 2006;Sonne et al, 2006a;Whalen et al, 1999). The high exposure of cetaceans from Brazil to cadmium (Dorneles et al, 2007a(Dorneles et al, , 2007b, mercury (Lailson-Brito et al, 2012a), organochlorine pesticides (Lailson-Brito et al, 2011, 2010, 2012b, as well as to organotin (Dorneles et al, 2008b), perfluoroalkyl (Dorneles et al, 2008a) and organobrominated (Alonso et al, 2012;Dorneles et al, 2010) compounds has already been reported. Therefore, the possibility of synergistic effects among these PBTs should not be ruled out.…”

“…25,[33][34][35][36][37] Os congêneres mais comumente encontrados são o PBB 153 e outros de baixa bromação como o PBB 29, 49, 52, 56, 77 e 80. 34,35,38,39 Resíduos de PBBs foram detectados em compartimentos ambientais como lodo de tratamento de efluentes domésticos na Austrália e em amostras de diversas espécies de peixes de valor comercial da Polônia e França, do Mar Báltico e do nordeste dos EUA, em cetáceos da costa sul e sudeste do Brasil e do Atlântico Norte, aves e ar do Ártico e em pandas na China. 15,33,34,[39][40][41][42] Muitos trabalhos referem-se especialmente ao acidente ocorrido em Michigan ou a região de descarga de efluentes da Michigan Chemical Corporation.…”
