Electroplating is one of the most significant sources of perfluorinated and polyfluoroalkyl substances (PFASs) in the environment. In this study, the occurrence of PFASs in soil of a relocated electroplating plant was analyzed. The probabilistic health risk was evaluated using Monte Carlo simulation, and the soil screening levels of PFASs were suggested. The soil samples were detected with 8PFASs, and perfluorooctane sulfonate (PFOS) was detected with the highest detection frequency of 89% and concentration of 388ng/g among the targeted PFASs. The distribution of PFASs in soil was impacted by the locations of production units. The total concentration and concentrations of single PFAS such as PFOS, perfluorohexane sulfonate (PFHxS) were significantly higher in soil at chromium plating department (P<0.05). Intake through human oral exposure of soil PFASs accounted for 75.2%~77.6%. Carcinogenic risk of perfluorooctanoic acid (PFOA) was 6.22×10-11, showing no carcinogenic risk in soil. Non carcinogenic risk quotient of PFOS was larger than 1based on the deterministic values of the exposure factors, while other PFASs showed no non carcinogenic risk. Monte Carlo simulation showed that the risk quotient of PFOS ranged from 0.731 to 5.38, with 95% quantile being 3.85. The 95% quantile values of risk quotient of other PFASs were between 8.77×10-6 and 0.0137. The soil screening levels of targeted PFASs ranged from 78 to 38826ng/g, and PFOS was found to have the most strict level of 78ng/g.
