本研究特别关注三种酚类内分泌干扰化合物（EDCs），双酚A（BPA），4-壬基酚（4-NP）和4-叔辛基酚（4-t-OP），它们存在于城市环境中，是几种人类活动的结果，也可以通过降雨径流进行。研究了珠江流域BPA、4-NP和4-t-OP的分布特征，并估算了惠州和东莞地区降雨径流、污水处理厂出水和工业废水中BPA、4-NP和4-t-OP的质量负荷。这3种酚类内分泌干扰物在东江干流和支流中检出频率较高，表层沃茨和沉积物中4-NP的最大浓度分别为14,540 ng/L和3088 ng/g。BPA在降雨径流样品中的浓度很高，惠州和东莞地区的最高浓度分别为5873和2397 ng/L，而4-NP和4-t-OP的浓度则为每升数十至数百纳克。降雨径流中酚类内分泌干扰物的质量负荷是污水处理厂出水的3-62倍，表明降雨径流是酚类内分泌干扰物进入受纳沃茨的重要来源。源和支流显示中到高的雌激素风险，而低到中的风险被发现在主流中，这意味着源控制应集中。
This study pays a special attention to three phenolic endocrine disrupting compounds (EDCs), — bisphenol A (BPA), 4-nonylphenol (4-NP), and 4-tert-octylphenol (4-t-OP) — that are present in urban environments, resultant of several anthropogenic activities that can be also carried through rainfall runoff. We investigated the distributions of BPA, 4-NP, and 4-t-OP in Pearl River basin and estimated the mass loads in rainfall runoff, wastewater treatment plant (WWTP) effluents, and industrial wastewater from urbanized Huizhou and Dongguan regions. These three phenolic EDCs were detected frequently in tributaries and mainstream of Dongjiang River with the maximum 4-NP concentrations of 14,540 ng/L in surface waters and 3088 ng/g in sediments. BPA showed high concentrations in rainfall runoff samples with maximum concentrations of 5873 and 2397 ng/L in Huizhou and Dongguan regions, respectively, while concentrations for 4-NP and 4-t-OP were detected at tens to hundreds of nanograms per liter. Mass loads of phenolic EDCs from rainfall runoff were 3–62 times higher than those of WWTP effluents, suggesting rainfall runoff is an important source of phenolic EDCs into receiving waters. Sources and tributaries showed median to high estrogenic risks, while low to median risks were found in mainstream, implying the source control should be focused.
