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 α-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.
几种被称为微污染物的化学物质在日常活动中被使用，它们对人类健康和环境都构成风险。其中一些物质除了导致重大公共卫生问题和危及一些水生物种外，还会扰乱内分泌系统。本研究的目的是调查巴西塞尔希培州一个供水系统（SAA）中内分泌干扰物和人为活动标志物的出现频率。2016年至2017年期间，从五个SAA点采集了22份水样。通过固相萃取对水样进行制备，并在与质谱仪联用的气相色谱仪中进行分析。总共评估了13种作为内分泌干扰物和人为活动标志物的化合物（邻苯二甲酸二乙酯、邻苯二甲酸二丁酯、壬基酚、五氯苯酚、双酚A、雄烷、雌酮、雌二醇、17α-乙炔基雌二醇、孕酮、粪甾醇、胆固醇和咖啡因）——包括原水（地下水和地表水）和处理后水（分配系统和水库）样本。根据我们的结果，50%的样本含有咖啡因；45.5%含有胆固醇；31.81%含有邻苯二甲酸二乙酯；31.81%含有邻苯二甲酸二丁酯；18.18%含有双酚A；4.54%含有雌二醇。因此，制定和实施关注公众健康以及确保水生生态系统安全的公共政策非常重要。
