水体中多环芳烃的来源、迁移及转化

Sources, Transportation and Inversions of Polycyclic Aromatic Hydrocarbons in the Water Bodies

本文概述了环境中多环芳烃(PAH)的三种主要来源:生物合成、化石燃料的开采与利用、有机物的热分解;迁移入水体的四种主要途径:石油泄漏、空中沉降、土壤雨水径流、污水排放;以及水体中PAH的两种主要转化方式:光氧化、生物降解。

This article deals generally with three kinds of main sources of polycyclic aromatic hydrocarbons(PAH) in the environment: biosythesis, exploitation and utilization of fossil fuels, pyrolysis of organic substances; four kinds of main path for PAH entering into the water bodies: Petroleum leakage, atmospheric fallout, surface runoff, waste water drainge; and two kinds of main inversion way of PAH in the water bodies: photooxidation and biodegradation。
