Resumo


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 Curitibaand 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 ofBrazil 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.
