Polycyclic aromatic hydrocarbons (PAHs) are widespread, persistent, and toxic environmental pollutants. Many anthropogenic and some natural factors contribute to the spread and accumulation of PAHs in aquatic and soil systems. The effective and environmentally friendly remediation of these chemical compounds is an important and challenging problem that has kept scientists busy over the last few decades. This review briefly summarizes data on the main sources of PAHs, their toxicity to living organisms, and physical and chemical approaches to the remediation of PAHs. The basic idea behind existing approaches to the bioremediation of PAHs is outlined with an emphasis on a detailed description of the use of bacterial strains as individual isolates, consortia, or cell-free enzymatic agents.
多环芳烃（PAHs）是广泛存在、持久且有毒的环境污染物。许多人为因素和一些自然因素导致了多环芳烃在水生和土壤系统中的扩散和积累。对这些化合物进行有效且环境友好的修复是一个重要且具有挑战性的问题，在过去几十年里一直让科学家们忙碌不已。本综述简要总结了多环芳烃的主要来源、它们对生物体的毒性以及多环芳烃修复的物理和化学方法的数据。概述了现有多环芳烃生物修复方法背后的基本理念，重点详细描述了将细菌菌株作为单独分离物、菌群或无细胞酶制剂的应用。
