Modeling the dispersion of endocrine disruptors in the Santos Estuarine System (Sao Paulo State, Brazil)

Estrogenios sao hormonios responsaveis pelo crescimento e reproducao, sendo naturalmente sintetizados por animais e seres humanos. Os xenoestrogenios sao hormonios identicos aos naturais, porem fabricados pelo homem e utilizados como contraceptivos orais. Xenoestrogenios formam um grupo especifico de farmacos encontrados em efluentes domesticos e em algumas matrizes ambientais. Estes compostos persistem nos tratamentos convencionais de esgotos e, consequentemente, atingem os ambientes e os organismos aquaticos nao alvos. Neste trabalho, foi estimada a dispersao de estrogenios naturais e sinteticos quando estes sao possivelmente lancados no Sistema Estuarino de Santos e Sao Vicente e Baia de Santos, utilizando o modelo hidrodinâmico Delft3D. Os dados das vazoes de estacoes de tratamento de esgotos e de concentracoes medias de estrogenios naturais e sinteticos lancadas nos ambientes aquaticos foram obtidos da literatura. Os resultados mostraram concentracoes mais elevadas de estrogenios nas aguas estuarinas da regiao do Largo da Pompeba, Canal de Sao Vicente, e na Baia de Santos, sendo estas as regioes que recebem maior aporte de esgotos domesticos. Os resultados da modelagem sugerem ainda que maiores concentracoes dos compostos estrogenicos sao esperadas nos locais com niveis mais elevados de salinidade.
