Assessment of Heavy Metal Pollution of Urban Roadside Soil with Set Pair Analysis and Geoaccumulation Index
The assessment of pollution levels of heavy metals soil contamination is significant to the health of human kind. Two methods, Set Pair Analysis (SPA) and Geoaccumulation Index (Igeo), are applied to assess the urban roadside soil heavy metals pollution levels and compare the assessment results with Fuzzy Comprehensive Analysis (FCA). The assessment results of SPA are inconsistent with the FCA. The ranks of roadside soil heavy metals, assessed by Igeo, indicate that the result of FCA is determined by most contaminated heavy metal, the SPA is determined by the contents distribution of all elements. The mean and standard deviation of heavy metal content in research soils are applied to establish an assessment standard and this method is also applicable if there is lower differentiation rate or no uniform standards.
