Endocrine-disrupting compounds (EDCs) are exogenous substances that cause adverse health effects in an intact organism, or its progeny, subsequent to the changes in endocrine function. Recent studies have shown that wastewater treatment plant effluents play an important role in the release of EDCs into aquatic environments. Therefore, in this study, influent and effluent samples from three different wastewater treatment plants (WWTPs) in Istanbul were analysed for the presence of the principal EDCs. These chemicals include steroids and synthetic organic chemicals. Thus, the occurrence and fate of EDCs of great health concern were monitored at three WWTPs in Istanbul. Furthermore, these WWTPs are employing different treatment processes. Therefore, the EDC removal performances of different treatment regimes were also evaluated. Phytosterol was the most abundant EDC in the influent samples. Second group of compounds at high influent levels were alkyl phenols. Pesticide levels of all three WWTP influent samples were low. Pasakoy Advanced WWTP is more effective at eliminating EDCs. Kadikoy Primary WWTP exhibits the lowest EDC elimination efficiencies. To the best of our knowledge, this work comprises the first detailed report on the occurrence and behaviour of both natural and synthetic EDCs in WWTPs of Istanbul and Turkey. The steroid estrogen levels of this study are higher than the previously documented values, except the levels given for Gaobeidian WWTP in Beijing, China. This is attributed to higher population densities of Beijing and Istanbul and as well as to lower individual water consumption rates in the two cities.
内分泌干扰物 (EDCs) 是指外源性物质，它们会在完整的生物体或其后代的内分泌功能发生变化后，引起不良健康影响。最近的研究表明，污水处理厂的废水排放对环境中 EDCs 的释放起着重要作用。因此，在本研究中，对伊斯坦布尔三个不同污水处理厂 (WWTP) 的进水和出水样本进行了分析，以确定主要 EDCs 的存在情况。这些化学物质包括类固醇和合成有机化学品。因此，在伊斯坦布尔的三个 WWTP 监测了对健康有重大影响的 EDCs 的发生和命运。此外，这些 WWTP 采用了不同的处理工艺。因此，还评估了不同处理方案的 EDC 去除性能。植物甾醇是进水样本中最丰富的 EDC。高进水水平的第二组化合物是烷基酚。所有三个 WWTP 进水样本中的农药水平都较低。Pasakoy 高级 WWTP 在去除 EDC 方面更有效。Kadikoy 初级 WWTP 的 EDC 去除效率最低。据我们所知，这项工作是伊斯坦布尔和土耳其 WWTP 中天然和合成 EDCs 的发生和行为的首次详细报告。本研究中的类固醇雌激素水平高于之前记录的值，除了中国北京高碑店 WWTP 的水平。这归因于北京和伊斯坦布尔的人口密度更高，以及这两个城市的个人用水量较低。
