- Occurrence of female sexual hormones in the Iguazu river basin, Curitiba, Paraná State, Brazil Karina Scurupa Machado Fernanda Dittmar Cardoso Julio Cesar Rodrigues Azevedo Cristina Borba Braga Ingeniería water quality Contraceptives liquid chromatography Female sexual hormones have attracted the attention of the scientific community due to the effects that they cause by interfering in the endocrine system. Many contemporary studies have sought to monitor some of the main female sexual hormones in surface waters in Brazil. Current article evaluates the presence of 17β-estradiol, 17α-ethinylestradiol, estrone and progesterone in the surface waters of Curitiba and the surrounding metropolitan area in the state of Paraná, Brazil, by high-performance liquid chromatography (HPLC), performed at 7 different sites. The study revealed that a range of concentrations between 0.07 and 13.45 μg L-1 of female sexual hormones was extant; higher values than these were found in other regions of Brazil and in other countries. Higher concentrations have been attributed to the region´s sanitation due to large sewage amounts. Sewage discharge has also been confirmed by results of limnological parameters. 2014 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303231059006 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
