The spatio-temporal distributions and the ecological and health risks of PAEs in surface water of Lake Chaohu, the fifth largest lake in China, were studied based on the monthly monitoring of six PAE congeners from May 2010 to April 2011. The annual total concentration of the six PAE congeners (Σ6PAE) in the surface water ranged from 0.467 to 17.953 μg L(-1), with the average value of 4.042±3.929 μg L(-1). The di-n-butyl phthalate (DnBP) that dominated the Σ6PAE at 65.8% was found at its highest and lowest levels in the western lake (TX) and eastern drinking water source area (JC), respectively. The temporal distributions of Σ6PAE showed that the highest and lowest levels were observed in September 2010 and June 2010, respectively. The different relationships between the runoff and the PAEs with low and high levels of carbon might suggest their different sources. The DnBP had much greater ecological risks than the other studied PAE congeners as indicated by its potential affected fractions (PAFs) and the margin of safety (MOS10). The PAE congeners studied posed little health risk to the nearby male and female citizens.
基于 2010 年 5 月至 2011 年 4 月对巢湖五种主要邻苯二甲酸酯（PAE）同系物的逐月监测，研究了它们在巢湖表层水中的时空分布特征、生态风险和健康风险。巢湖表层水中六种 PAE 同系物（Σ6PAE）的年浓度范围为 0.467-17.953μg/L，平均值为 4.042±3.929μg/L。Σ6PAE 中以邻苯二甲酸二丁酯（DnBP）为主，占 65.8%，其浓度在西半湖（TX）和东部饮用水源区（JC）最高和最低。Σ6PAE 的时间分布表明，2010 年 9 月和 6 月浓度最高和最低。径流量与低和高浓度碳 PAE 之间的不同关系可能表明它们具有不同的来源。DnBP 的潜在影响分数（PAFs）和安全边际（MOS10）表明其生态风险远大于所研究的其他 PAE 同系物。研究中所涉及的邻苯二甲酸酯同系物对附近男性和女性居民的健康风险较小。
