摘要：
Gas chromatography-mass spectrometry was utilized to determine the contents of PAHs in plants and soil collected around several highways and three scenic areas in Xinjiang. The concentrations of Σ16 PAHs ranged from 18.82 to 2 153.54 ng.g -1 in 11 soil samples from 11 sampling sites, with an average value of 425.95 ng.g -1. The concentrations of Σ16 PAHs ranged from 9.93 to 748.30 ng.g -1 in 59 plant samples from 36 sampling sites, with an average value of 154.11 ng.g -1. In the plant samples, the order of the average content with different ring numbers of PAHs were ranked as low rings (2-3 rings) > middle rings (4 rings) > high rings (5-6 rings), and in soil samples, the order of the average content with different ring numbers of PAHs were ranked as middle rings (4 rings) > high rings (5-6 rings) > low rings (2-3 rings). According to the ratios of indicator PAHs and principal component analysis, PAHs in soil and plant samples came from various sources, mainly the burning of fossil fuels and biomass. The main sources of PAHs in soil were combustion and petroleum, and the main sources of PAHs absorbed by plants were wood burning and coking industries. The carcinogenic risk (CR) of soil PAHs in the Korla section of the S323 provincial road to road workers was 1.26 x10 -6, indicating potential health risks. © 2022 Science Press. All rights reserved.
