  • 摘要: 本研究调查了天津市松针中6种可挥发PFASs的浓度水平,旨在探讨松针作为可挥发PFASs天然被动采样装置的可行性.结果表明,松针中可挥发PFASs的总浓度范围为0.43—45.69 ng·g-1(脂质),平均浓度4.92 ng·g-1(脂质),不同采样点PFASs的浓度水平存在差异.8:2氟调醇和10:2氟调醇是松针中的主要检出物,8:2氟调醇的检出率高达85%,浓度在0.23—17.46 ng·g-1(脂质)之间,10:2氟调醇全部被检出,浓度范围为0.43—28.23 ng·g-1(脂质);N-乙基全氟辛烷磺酰胺和N-乙基全氟辛烷磺酰胺基乙醇的检出率较低;而N-甲基全氟辛烷磺酰胺基乙醇和6:2氟调醇在松针中未被检出.松针中氟调醇的浓度水平随着碳链长度增加而增加.与大气被动采样器相比,松针可作为被动采样的一种形式,从一定程度上反映大气中可挥发PFASs的浓度水平.
    Abstract: Per(Poly)fluoroalkyl substances (PFASs) are ubiquitous in environmental media. As a new group of persistent organic pollutants (POPs), they have drawn much scientific attention in recent years. Pine needles, a commonly used passive air sampler, have been reported to be an indicator of atmospheric contamination levels of hydrophobic organic compounds, such as polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). In the present study, the levels of six volatile PFASs were detected in pine needles of Tianjin to check their applicability in monitoring this group of new POPs. The results showed that the concentrations of the tested PFASs ranged from 0.43 to 45.69 ng·g-1(lipid), with the average concentration being 4.92 ng·g-1(lipid). The tested PFAS levels varied among different sampling sites. 8:2 fluorotelomer alcohol (8:2FTOH) and 10:2 fluorotelomer alcohol (10:2 FTOH) were the predominant PFASs in pine needles. The detection frequency of 8:2 FTOH was as high as 85%, with concentrations of 0.23—17.46 ng·g-1(lipid). And 10:2FTOH were detected in all samples, with the concentrations of 0.43—28.23 ng·g-1 (lipid). N-methyl perfluorooctane sulfonamidoethanol and 6:2 fluorotelomer alcohol (6:2FTOH) were not detected, and the detection rates of N-ethyl perfluorooctane sulfonamidoethanol and N-ethyl perfluorooctane sulfonamide were low. The concentrations of fluorotelomer alcohols increased with the carbon chain length. Compared with the atmosphere passive sampler, pine needles can be proposed as a form of passive sampling to reflect the levels of volatile PFASs in the atmosphere to some extent.
