Resumen
Several chemical substances known as micropollutants are used in daily activities, and they pose
risks to both human health and the environment. Some of these substances disrupt the endocrine
system in addition to being responsible for major public health issues and for endangering some
aquatic species. The aim of this research is to investigate the frequency of endocrine disruptors
and anthropogenic activity markers in a Water Supply System (SAA) in Sergipe State, Brazil.
Twenty-two water samples were collected from five SAA points from 2016 to 2017. They were prepared
through solid phase extraction and analyzed in a gas chromatographer coupled to a mass
spectrometer. In total, 13 compounds (diethyl phthalate, dibutyl phthalate, nonylphenol, pentachlorophenol,
bisphenol A, androstane, estrone, estradiol, 17 a-ethinyl estradiol, progesterone, coprostanol,
cholesterol and caffeine) that are endocrine disruptors and antrophic activity markers
were herein assessed ??? both in raw (underground and surface) and treated water (distribution system
and reservoir) samples. Based on our results, 50% of the samples contained caffeine; 45.5%,
cholesterol; 31.81%, diethyl phthalate; 31.81%, dibutyl phthalate; 18.18%, bisphenol A; and 4.54%,
estradiol. Therefore, it is important to create and implement public policies focused on public
health and on assuring the safety of aquatic ecosystems.
