沈阳市主要公园土壤多环芳烃污染特征研究
Study on the soil PAHs pollution characteristics of main parks in Shenyang
摘要
Abstract
Soil samples were collected from 7 major parks in Shenyang in March,2017.The concentrations of 15 Polycyclic Aromatic Hydrocarbons(PAHs)were analyzed with a High-Performance Liquid Chromatography (HPLC)method.Results show that the characteristics of PAHs pollution in the parks are different,that is,the main pollution components are obviously discrepant.The pollution level is the highest in Wanquan Park where the con-centration of PAHs in soil samples is much higher than those in the other sample points.With the increase of soil depth,PAHs concentrations in the studied parks in Shenyang all show a decreasing trend.Analyzing the proportions of PAHs of different ring numbers in soil samples indicates that the content of middle and high ring pollutants is higher and derives from fuel combustion,while the low ring pollutants content is relatively low.Besides,further a-nalysis based on the ratio method shows that the sources of PAHs in Shenyang parks are mainly the high-tempera-ture combustion of fuel,i.e.the mixture of coal,petroleum,and biomass.关键词
