Spatial distribution and pollution evaluation of heavy metal in soils surrounding a typical municipal solid waste incineration plant
摘要
Abstract
Incineration of municipal solid waste (MSW) for energy recovery is a desired option in modern societies as increase in quintiles of MSW. However, the gaseous and particulate heavy metals emitted from MSW incinerators may accumulate in the soil entering via dry and wet deposition, which can cause great concern for the population living nearby. In this study, soil samples around the typical municipal solid waste incineration (MSWI) plant in Hangzhou-Jiaxing-Huzhou Plain were collected. The concentrations of heavy metal were determined with X-ray fluorescence spectrometry (XRF), atomic absorption spectrometry (AAS) and mercury analyzer. Mean concentrations of Cr, Mn, Cu, Pb and Fe were 174.05、707.76、47.68、41.95 and 39 057.89 mg·kg-1 in this region, respectively. Compared with background values by Cultural Enrichment Factor (CEF), Pb and Cu concentrations were higher than their corresponding background values, respectively. Factor analysis of geo-statistics was also performed. The results showed that the heavy metal distribution patterns were dominantly affected by three principal components: local geochemical characteristics (Cr, Mn and Fe, 37.88%of variance),impact of the pesticide application (Cu, 22.06%of variance) as well as MSWI plant (Pb, 22.74%of variance). The results also showed that the investigated region has low degree of heavy metal pollution. The major heavy metal pollution contribution is Pb (Pollution index=2.16). MSWI plant has a noticeable impact on heavy metal accumulation in surround areas.关键词
