摘要

多环芳烃（PAHs）是一类对生态系统和人类健康具有严重毒性影响的芳香烃。本研究选择了典型喀斯特地区的荔浦河流域作为案例，研究人类活动对地表水中多环芳烃的分布和归宿的影响。结果显示，所有样本中都检测到了 16 种重点控制的多环芳烃。工业活动排放的 PAHs 是主要污染源，交通排放、生物质燃烧和农业源地表径流等非点污染源也是造成 PAHs 高浓度的原因。多种多环芳烃并存，对水生生物和人类健康构成高风险。地表水水质不断改善，但水污染问题依然存在。本研究的结果为环境保护和政策制定提供了宝贵的理论支持。

Composition characteristics, source analysis and risk assessment of PAHs in surface waters of Lipu

Polycyclic aromatic hydrocarbons (PAHs) are a group of aromatic hydrocarbons with serious toxic effects on ecosystems and human health. In this study, Lipu River Basin in a typical karst area was selected as a case to study the influence of anthropogenic activities on the distribution and fate of PAHs in surface water. The results showed that 16 priority controlled PAHs were detected in all samples. PAHs discharges from industrial activities were the primary pollution sources, and the non-point sources such as traffic emission, biomass combustion and surface runoff with agricultural origin also contributed to the high PAHs concentrations. The coexistence of multiple PAHs posed a high risk to the aquatic organisms and human health. The quality of surface water was continuously improved, but water pollution problems remain. The results of this study provide valuable theoretical support for environmental protection and policy making.

期刊介绍： The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
