摘要：Estradiol is known as the indicator of the presence of hormones as Endocrine Disruptor Compounds (EDCs) in water and wastewater. The entrance of these compounds into water resources through daily liquid wastes of societies as well as pharmaceutical industries, ranching, and pathology laboratories leads to an increase in their concentrations in these resources. Consequently, due to the metabolic properties of these substances they can cause adverse effects on consumers and aquatics. The main purpose of this research is to determine the occurrence and the fate of estradiol as indicator of endocrine-disrupting compounds in drinking water, surface water, and wastewater in Ahvaz, Iran. 17β-estradiol was detected in 37.5% of samples obtained from drinking water and 68.75% of samples from the Karun River. In the urban drinking water and Karun River, the mean concentrations of 17β-estradiol were 2.96 and 13.66 ng l-1, respectively.
