摘要

随着城市化进程的推进,东北黑土区土壤受到了多环芳烃(PAHs)污染。本研究在吉林省黑土农业区采集了119个表层土壤样品,对16种多环芳烃的特征和空间分布进行了研究。农业土壤中∑16 PAHs总浓度为2.546 ~ 33.993 mg/kg,平均值为9.99 mg/kg。正矩阵分解(PMF)分析表明,汽车尾气和燃油燃烧是交通和能源相关污染的主要来源。该地区遗传终生致癌性风险(ILCR)较低,潜在风险较低,成人(1.34 × 10-5)高于青少年(8.62 × 10-6)和儿童(7.49 × 10-6)。在摄入、皮肤接触和吸入途径中观察到的最高值在成人组,这表明某些地区的成年居民可能面临更高的健康风险。本研究增强了我们对多环芳烃进入吉林省农业土壤的途径的理解,并为解决黑土中多环芳烃污染提供了见解,最终有助于该地区更可持续的农业实践。

PAH Contamination, Sources and Health Risks in Black Soil Region of Jilin Province, China.

Soils in the Black Soil Zone of northeast China are experiencing pollution from polycyclic aromatic hydrocarbons (PAHs) as the region undergoes urbanization. In this study, 119 topsoil samples were collected from the black soil agricultural area in Jilin Province, China to investigate the characteristics and spatial distribution of 16 PAHs. The total concentration of ∑16 PAHs in the agricultural soils ranged from 2.546 to 33.993 mg/kg, with a mean value of 9.99 mg/kg. Positive matrix factorization (PMF) analysis indicated that vehicle exhaust and oil combustion were identified as the main contributors to traffic- and energy-related pollution. The inherited lifetime carcinogenicity risk (ILCR) was found to be relatively low, indicating a low potential risk in this region, with adults (1.34 × 10-5) exhibiting a higher risk than adolescents (8.62 × 10-6) and children (7.49 × 10-6). The highest values for intake, skin contact, and inhalation routes were observed in the adult group, suggesting that adult residents in certain areas may be at increased health risk. This study enhances our understanding of the pathways through which PAHs enter agricultural soils in Jilin Province and provides insights that could aid in addressing PAH pollution in black soil, ultimately contributing to more sustainable agricultural practices in the region.

期刊介绍: Toxics (ISSN 2305-6304) is an international, peer-reviewed, open access journal which provides an advanced forum for studies related to all aspects of toxic chemicals and materials. It publishes reviews, regular research papers, and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in detail. There is, therefore, no restriction on the maximum length of the papers, although authors should write their papers in a clear and concise way. The full experimental details must be provided so that the results can be reproduced. Electronic files or software regarding the full details of calculations and experimental procedure can be deposited as supplementary material, if it is not possible to publish them along with the text.
