“…[3][4][5] Many compounds are suspected of interfering with the endocrine system, 6 including natural and synthetic estrogens (lipidsoluble steroid hormones) such as 17a-ethynylestradiol, polycyclic aromatic hydrocarbons (compounds containing two or more conjugated aromatic rings, such as benzo(a) anthracene), polychlorinated biphenyls (highly toxic chlorinated compounds), pesticides (substances such as dichlorodiphenyltrichloroethane (DDT), used to repel or eliminate pathogenic insects), and plasticisers such as bisphenol A that are used in polymeric plastics. 7 ED are conveyed to aquatic systems by various natural or anthropogenic mechanisms. Their presence in surface waters is often due to discharge of domestic and/or industrial effluents.…”

“…Legal restrictions to the use of PCBs in Brazil were implemented in 1981, when the prohibition of fabrication, commercialization and use of PCBs was established in the country. However, the same legislation mentioned that equipments that had been already installed, in which PCB was used, could keep on working up to the replacement either of the whole machine or the dielectric fl uid by one other than PCB (Penteado & Vaz 2001).…”

“…Os dois primeiros algarismos representam o tipo molecular (12 átomos de carbono) e os dois últimos a porcentagem de cloro na composição do produto comercial. Assim, o produto aroclor 1254 é uma mistura de bifenilas policloradas contendo 54% de cloro [1][2][3][4] . O ascarel é comercializado como sendo uma mistura composta de 75% da espécie aroclor 1254 e 25% de triclorobenzeno.…”
