Abstract

This project aims to acess aquatic pollution by some phenolic microcontaminants as chlorophenols (triclosan-TCS and methyltriclosan-MTCS), alkylphenols (nonilphenol-NP and octylphenol-OP) and bisphenol A-BPA in surface sediments collected in coastal regions of São Paulo State that receives urban and industrial effluents through submarine outfalls. These compounds are considered as endocrine disruptors and can affect reproductive physiology of a range of species. The majority of studies concerning to these pollutants refer to sewage treatment plants and rivers that received these effluents; however few studies were conducted for coastal areas worldwide. Thus, the present project aims to verify the occurrence of these microcontaminants in coastal regions, especially close to submarine outfalls from the State of São Paulo, as well as to evaluate if the exposure of fishes to such compounds, in environmental concentrations, can produce effects of endocrine disruption on these organisms through vitellogenin, biotransformation enzymes, and histopathological biomarkers analysis. This project will be conducted under supervision of Prof. Mary Rosa Rodrigues de Marchi from Institute of Chemistry of São Paulo State University (UNESP) in Araraquara, with collaboration in Brazil, of Prof. Denis Moledo de Souza Abessa from UNESP São Vicente. Foreign, this project taking account the partnership with Prof. Rai Kookana from Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia which have been investigating the occurrence of these compounds in coastal regions.
