五大连池药泉湖表层沉积物中多环芳烃的分布及来源解析

Distribution and sources of polycyclic aromatic hydrocarbons in the surface sediment of Wudalianchi Drug Spring Lake

开展了五大连池药泉湖表层沉积物中多环芳烃含量的检测工作,结果显示,药泉湖东南部表层沉积物中,多环芳烃的含量远大于西北部,组成以3环、4环、5环化合物为主,主要来源于煤炭、木材、石油的不完全燃烧。

The content of polycyclic aromatic hydrocarbons in surface sediments of Wudalianchi Drug Spring Lake was detected. The result shows：the content in southern was more than the northwest, and 3, 4, 5 ring compounds were main ingredients. The incomplete combustion of coal, wood, oil was the main sources.
