以4家重点监管单位连片区域表层土壤为研究对象,利用相关性分析、主成分分析和正定矩阵因子分解(PMF)模型探究重点监管企业连片区域土壤重金属来源.结果表明,区域内土壤中重金属来源主要为工业源、交通源、自然源和居民生活源,其综合贡献率分别为38.38%、29.71%、19.70%和12.21%;其中Cd、As主要来源为工业源,Pb和Zn的主要来源为工业源和交通源,Cr、Ni、Cu主要来源为自然源,Hg主要来源为居民生活源.
Source Apportionment of Heavy Metals in Topsoil of Typical Key Supervision Enterprises Contiguous Area
Based on the topsoil of typical key supervision enterprises contiguous area,correlation analysis,principal compo-nent analysis and positive definite matrix factorization(PMF)models were used to explore the sources of heavy metals in soil of the contiguated areas of key supervision enterprises.The main sources of topsoil heavy metals in the study area were indus-trial sources,transportation sources,natural sources and residents sources,with contribution rates of 38.38%,29.71%,19.70%and 12.21%,respectively;Among them,the main sources of Cd and As are industrial sources,the main sources of Pb and Zn are industrial sources and transportation sources,the main sources of Cr,Ni and Cu are natural sources,and the main sources of Hg are residents sources.
