Recebido em 5/5/09; aceito em 14/9/09; publicado na web em 12/2/10 ESTROGENS IN NATURAL AND TREATED WATERS IN THE REGION OF JABOTICABAL -SÃO PAULO, BRAZIL. The aim of this work was to analyze 17 b estradiol and estrone, natural estrogenic hormones present in domestic effluents and animal excreta, in the public water supply system of Jaboticabal, SP. The results have shown the presence of estrogens in 22% of the samples in concentrations from 6,8 ng L -1 (treated water) to 30,6 ng L -1
more » ... 6 ng L -1 (riverhead) for 17 b estradiol and 600 ng L -1 of estrone (stream), respectively. We concluded that animal wastes, discharges from the wastewater treatment station, and discharges of domestic effluent without treatment from rural proprieties were probably the cause of this contamination.
