新疆2个典型甜瓜产区土壤重金属污染水平及来源解析
Analysis of Soil Heavy Metal Pollution Levels and Sources in Melon Fields in Two Typical Producing Areas of Xinjiang
摘要
Abstract
In order to determine the level and sources of soil heavy metal pollution in two typical melon fields in Xinjiang,183 soil samples were selected as the research objects,according to the Inductively Coupled Plasma Mass Spectrometry for Soil Heavy Metal Determination(DB 65T3974-2017),the content of six heavy metals,Cr,Ni,As,Cd,Pb,and Cu,in soil samples was analyzed by inductively coupled plasma mass spectrometry(ICP-MS).The single factor pollution index and Nemero comprehensive pollution index,ground accumulation pollution index,and potential ecological risk index of soil samples were calculated.A health risk assessment model was used to evaluate the pollution levels of six heavy metals in the samples,and principal component analysis was used to analyze the sources of the six heavy metals in the samples.The results showed that among the six heavy metals in the soil samples,the maximum values of As and Cd exceeded the risk screening values,indicating a relatively high degree of pollution.The Nemero comprehensive pollution index in the two production areas reached 3.74 and 1.40,respectively,indicating severe and mild pollution.In terms of land accumulation index,both production areas had the highest As pollution level.The health risks of heavy metal pollution to children were higher than those to adults,and the contribution rate of oral intake was relatively higher.Cr,Ni,and Cu in soil might be derived from parent materials,while human activities were an important source of As,Cd,and Pb in the samples.In summary,it is necessary to reduce the impact of human activities on soil As and Cd pollution in melon fields in the study area through various means.关键词
