High levels of perfluoroalkyl substances (PFASs) were observed in rural areas near a fluorochemical industrial park (FCIP) in the Yangtze River Delta region. The concentrations of total PFAS (∑PFASs) in soil, surface water, groundwater, and rainwater were in the range of 0.6-64.6 ng/g dry weight, 15.6-480.9, 4.8-614.6, and 13.4-542.2 ng/L, respectively. PFASs in rainwater and groundwater were higher than in surface water. The influence of the FCIP on rural soils extended to a distance of approximately 4 km based on the changes in PFAS compositions. The impact on surface water is mainly through direct river flow connected with contaminated sources, which may extend farther than 7 km in the case of unrestricted flow but much shorter distance for unconnected rivers. The penetration of PFASs in groundwater aquifers can extend as far as ca. 6 km, while direct water flow is the main transport route for PFASs. The influence radius of the FCIP can be as far as 60 km due to atmospheric precipitation.
在长三角地区的一个氟化工产业园区（FCIP）附近的农村地区，观察到高水平的全氟烷基物质（PFASs）。土壤、地表水、地下水和雨水中的总 PFAS（∑PFASs）浓度分别在 0.6-64.6ng/g 干重、15.6-480.9ng/L、4.8-614.6ng/L 和 13.4-542.2ng/L 的范围内。雨水中和地下水中的 PFASs 高于地表水中的 PFASs。基于 PFAS 成分的变化，FCIP 对农村土壤的影响范围约为 4 公里。对地表水的影响主要是通过与污染源头直接相连的河流流动造成的，在不受限制的水流情况下，其影响范围可能超过 7 公里，但对于没有连接的河流来说，距离要短得多。PFASs 可以渗透到距离约 6 公里的地下含水层中，而直接水流是 PFASs 的主要运输途径。由于大气降水，FCIP 的影响半径可达 60 公里。
