Resumo
Estrogens are hormones responsible for growth and reproduction. They are naturally
synthesized by animals and humans alike. Xenoestrogens are identical to natural
hormones, but they are manmade and used as oral contraceptives. Xenoestrogens are
a specific group of drugs found in domestic wastewater and some environmental
matrices. These compounds remain after conventional sewage treatment and,
consequently, affect both the environment and non-target aquatic organisms. In this
study, we used the Delft3D hydrodynamic model to estimate the amount of both
natural and synthetic estrogens that have been released in the Estuarine System of
Santos and São Vicente and the Santos Bay. The data on flow from the
sewage treatment plants and on average concentrations of natural and synthetic
estrogens released in aquatic environments were obtained from the literature.
The results of the modeling showed higher concentrations of estrogens in the estuarine
waters of the Largo Pompeba region, the São Vicente Canal, and the Santos Bay,
which are regions that receive greater inflows of domestic sewage. The results also
suggest that higher concentrations of estrogenic compounds are expected to be found
in areas with higher levels of salinity.
