  • 摘要: 本文对全氟化合物(PFASs)生产工厂厂内及周边土芯样品中的PFASs进行了研究.PFASs浓度范围为1.19—1495 ng·g-1 dw(干重),其中全氟辛基磺酸盐(PFOS)浓度在3个主要单体(全氟己基磺酸盐(PFHxS)、PFOS及全氟辛酸(PFOA))中处于最高水平.整体上,土芯中PFASs浓度由上到下呈下降趋势,其浓度与TOC呈正相关.在一个已经停产10年左右的生产企业周围土芯中仍然发现了较高浓度的PFASs,说明其在环境中存在着较强的持久性.
    Abstract: Perfluoroalkyl substances (PFASs) have received much attention in recent years. In this study, perfluorohexanesulfonate (PFHxS), perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA) were detected in soil cores around a PFASs manufacturing facility and an abandoned facility. PFASs concentrations were in the range of 1.19 to 1495 ng·g-1dw (dry weight). Thereinto, PFOS was the most abundant pollutant, followed by PFOA and PFHxS. PFASs concentrations showed decreasing trends from upper layers to the bottom of the soil core. The concentrations of PFASs were positively correlated with total organic carbons (TOC) of the samples. Besides, high levels of PFASs concentrations in soil samples from the abandoned facility indicated the persistence of PFASs in the environment.
