A fluorochemical industrial park was built in 2004 in Fuxin, China, for the production of polytetrafluoroethylene (PTFE) and perfluorobutane sulfonate (PFBS). Yet little is known about the distribution of fluorochemicals in the environment and in people living in and around the park. In this study, environmental samples were collected from 22 sites in Fuxin to investigate the extent of perfluorinated compound (PFC) contamination in the environment around the park, and in drinking water from the public water supply system and groundwater in shallow aquifers from private wells near the park. Serum samples were also collected from nonoccupationally exposed residents living in Fuxin to determine the PFC load of local residents. As the dominant contaminant of eight target PFCs, the maximum concentrations of perfluorooctanoic acid (PFOA) in sediment and river water of the River Xi along the industrial park were 48 ng/g dry weight and 668 ng/L, respectively; the highest PFOA concentration in groundwater beneath the park was 524 ng/L; and the PFOA levels in drinking water from the public water supply system ranged between 1.3 and 2.7 ng/L. In human serum, PFOA had the geometric mean at 4.3 ng/mL, ranging from 0.02 to 93 ng/mL. This study serves to document what should be the beginning of a long-term surveillance effort to minimize potential exposure of residents living in Fuxin.
2004 年,中国阜新市建成了一个氟化工产业园,用于生产聚四氟乙烯(PTFE)和全氟丁烷磺酸(PFBS)。然而,人们对于生活在该园区及其周边地区的人群和环境中氟化学物质的分布情况知之甚少。在这项研究中,从阜新市 22 个地点采集了环境样本,以调查园区周边环境中全氟化合物(PFC)的污染程度,以及公共供水系统的饮用水和园区附近私人井浅层含水层中的地下水。还从非职业暴露的当地居民中采集了血清样本,以确定当地居民的 PFC 负荷。作为八种目标 PFC 中的主要污染物,园区沿溪河水体和底泥中全氟辛酸(PFOA)的最大浓度分别为 48ng/g 干重和 668ng/L;园区下方地下水中 PFOA 的最高浓度为 524ng/L;公共供水系统饮用水中的 PFOA 浓度范围为 1.3-2.7ng/L。在人体血清中,PFOA 的几何平均值为 4.3ng/mL,范围为 0.02-93ng/mL。本研究旨在记录应该开始进行长期监测工作,以尽量减少阜新居民潜在的暴露风险。
