贵阳市表层土壤中多环芳烃的分布特征及来源解析
Distribution characteristics and source analysis of PAHs in topsoil of Guiyang City, Southwest China.
摘要
Abstract
Topsoil samples were collected from the urban and suburban areas of Guiyang City to determine the concentrations of 16 polycyclic aromatic hydrocarbons ( PAHs) by high performance liquid chromatography, with the distribution characteristics, pollution levels, and origins of the PAHs discussed. The total PAHs concentration in the samples varied from 61 to 1560 μg · kg-1, being 247-1560 μg · kg-1 for urban and 61 -339 μg · kg"' for suburban soils, respectively. In all the samples, PAHs were dominantly composed of 4- and 5-ring PAH species. Referred to some foreign environmental standards, the topsoil of Guiyang City was PAHs-contami-nated to some extent. The analysis with correlation coefficient method and triangle drawing dis-criminance based on typical sources showed that the possible sources of PAHs in the topsoil of Guiyang were mainly the combustion of coals and the combined contamination of coal combustion and traffic exhaust.关键词
