Estrogênios em águas naturais e tratadas da região de Jaboticabal - São Paulo

Abstract: 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 (riverhead) for 17 b estr… Show more

“…8 ED contamination of aquatic systems is especially problematic because most conventional water treatment processes are unable to completely eliminate the compounds. 9 Studies have found residues of pharmaceuticals and their metabolites, from ng L -1 to mg L -1 levels, in aquatic environments in countries including Germany, Brazil, Canada, Holland, UK, Italy, Sweden and the USA. [10][11][12][13] However, since these chemicals belong to an emerging class of pollutants, the literature is still sparse concerning their behavior and interactions in hydric systems.…”

“…Além destes, a progesterona e a testosterona são exemplos de outros hormônios naturais que, assim como os estrogênios, são excretados diariamente pela urina e podem ser determinados nos corpos d'água que recebem grandes aportes de esgoto doméstico. 7,9,18,[20][21][22][23][40][41][42]46,[51][52][53][54] Os estrogênios sintéticos, encontrados em produtos farmacêuti-cos, são esteróides que tiveram suas estruturas moleculares alteradas. Os principais usos estão relacionados aos contraceptivos, terapias de reposição hormonal e tratamento de neoplasias.…”

“…A dispersão no ambiente desses contaminantes se dá principalmente pela eliminação de esgoto doméstico tratado ou in natura, nos corpos d'água, efluentes industriais e pela aplicação de adubo orgânico oriundo de dejetos de animais, que posteriormente atingem mananciais superficiais por escoamento, ou aquíferos por infiltração (BERGÉ; VULLIET, 2015;LOPES et al, 2010).…”
