煤矿区多环芳烃扩散途径、分布机制研究进展

Study on Diffusion Path, Distribution Mechanism and Biodegradation of PAHs in Coal Mine Area

多环芳烃(PAHs)是最早被人类发现和研究的一类持久性环境污染物,多数产生于煤炭资源开采及利用过程,因其具有遗传毒性和致癌潜力,PAHs的污染问题及其环境效应逐渐被人们重视。本文对目前国内外学者对煤矿区环境中PAHs的来源、分布、迁移转化进行解析,为持续深入发掘创新性研究方向,控制污染源,限制传播途径、制定环保策略提供重要依据。

Polycyclic aromatic hydrocarbons (PAHs) were the first persistent environmental pollutants dis-covered and studied by human beings. PAHs were produced in the process of coal exploitation and utilization. Because of the genotoxicity and carcinogenic potential, PAHs pollution and its envi-ronmental effects have been paid more and more attention. In this paper, the sources, distribution, migration and transformation of PAHs in coal mine environment were analyzed by scholars at home and abroad. It provided an important basis for continuously exploring innovative research directions, controlling pollution sources, limiting communication channels and formulating envi-ronmental protection strategies.
