对中国12个污水处理厂的进水、出水和污泥中的全氟辛烷磺酸（PFOS）和全氟辛酸（PFOA）浓度进行了分析。发现城市污水处理厂和工业污水处理厂的进水中全氟辛烷磺酸和全氟辛烷磺酸浓度最高。相对于进水中全氟辛烷磺酸和全氟辛烷磺酸的浓度，采用厌氧-缺氧-缺氧废水处理工艺的污水处理厂出水浓度升高。重要的是，应用先前报道的基于沉积物吸附实验的有机碳归一化分配系数（K-OC）似乎低估了本研究中量化的生物固体中全氟辛烷磺酸和全氟辛烷磺酸的水平。发现污水中的全氟辛烷磺酸和全氟辛酸含量分别比接收污水的海水中检测到的含量高约27倍和2倍。然而，这一地区的海水中它们的含量还没有超过美国环保署发布的饮用水临时短期健康建议。(c) 2012 Elsevier Ltd.版权所有。
Concentrations of perfluorooctane sulfonate (PFOS) and perfluorooctanoate (PFOA) in influents, effluents and sludges were investigated by analyzing the samples from twelve wastewater treatment plants (WWTPs) in China. The highest concentrations of PFOS and PFOA in influents were found to occur in municipal and industrial WWTPs, respectively. Relative to PFOS and PFOA concentrations in influents, elevated concentrations were observed in effluents from WWTPs applying anaerobic-anoxic-oxic wastewater treatment process. Importantly, application of previously reported organic carbon normalized partition coefficients (K-OC) derived from sediment-based sorption experiments appear to underestimate the PFOS and PFOA levels in biosolids quantified in the current study. PFOS and PFOA levels in effluents were found to be approximately 27 and 2 times higher than those detected in the effluent-receiving seawater, respectively. However, their levels in this area of seawater haven't exceeded the provisional short-term health advisories in drinking water issued by U.S. EPA yet. (c) 2012 Elsevier Ltd. All rights reserved.
