The soil heavy metal pollution centered on landfills was often affected by the surrounding production and life. The traceability and risk assessment of different pollution sources were used to strengthen the scientific management of landfills and surrounding soils. Through literature review, field investigation and statistical methods, the environmental risk assessment and source analysis of heavy metals in landfill soil were studied. The results showed that Cr ((chromium)), Cd (cadmium), and Pb (lead) were typical soil heavy metals in the municipal solid waste landfills (MSW) in the study area. The Nemerow index of Cr was high, and the value reached 9.17, which was considered as serious pollution. Cd had potential ecological risks ( > 40), while Cd, Cu (copper) and As (arsenic) were greatly affected by parent materials. The health risk values of As and Cd in the study area (1.074E-04 and 1.366E-04) exceeded the tolerable value (10). Cr had high homology with Cd, Cu, Ni (nickel), and Pb, and was mainly derived from landfill and leachate leakage. Landfill, incineration plant and aquafarm were the main sources of heavy metals in this study.

以垃圾填埋场为中心的土壤重金属污染常受周边生产生活影响。利用不同污染源的溯源及风险评估，加强垃圾填埋场及周边土壤的科学管理。通过文献综述、实地调查和统计方法，对垃圾填埋场土壤重金属的环境风险评估及源解析进行了研究。结果表明，铬（Cr）、镉（Cd）和铅（Pb）是研究区域城市生活垃圾填埋场（MSW）典型的土壤重金属。Cr的内梅罗指数较高，值达9.17，属重度污染。Cd存在潜在生态风险（ > 40），而Cd、铜（Cu）和砷（As）受母质影响较大。研究区域内As和Cd的健康风险值（1.074E - 04和1.366E - 04）超过可容忍值（10）。Cr与Cd、Cu、镍（Ni）和Pb具有高度同源性，主要来源于垃圾填埋场及渗滤液渗漏。垃圾填埋场、焚烧厂和养殖场是本研究中重金属的主要来源。
