通过2010年5月至2011年4月对巢湖表层水体中6种PAE同族物的逐月监测，研究了巢湖表层水体中PAEs的时空分布特征及其生态健康风险。6种PAE同系物（Σ6PAE）在地表水中的年总浓度范围为0.467 ~ 17.953 μ L−1，平均值为4.042±3.929 μ L−1。邻苯二甲酸二丁酯（DnBP）在西部湖泊（TX）和东部饮用水源地（JC）中含量最高和最低，占Σ6PAE的65.8%。Σ6PAE的时间分布表明，最高和最低水平分别出现在2010年9月和2010年6月。径流与低碳和高碳的PAEs之间的不同关系可能表明它们的来源不同。从其潜在影响分数（paf）和安全边际（MOS10）可以看出，DnBP比其他研究的PAE同系物具有更大的生态风险。所研究的PAE同系物对附近的男性和女性公民的健康风险很小。
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.
