Heavy-metal pollution is a negative impact of municipal solid-waste landfills. The multiple pollution transport pathways (including leachate, runoff, and waste gas) and complex and co-existing potential pollution sources (such as agricultural activities) around landfills require a combination of different pollution assessment methods and source identification tools to address pollution distribution and potential risks. In this study, the distributions of eight heavy metals (chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), arsenic (As), cadmium (Cd), and mercury (Hg)) around a landfill were analyzed using 60 topsoil samples. Ecological risk assessments indicated that there are currently no ecological risks. Based on health risk assessments, however, high concentrations of Cr and As in the soil pose a noncarcinogenic and carcinogenic risk to humans in the study area, respectively. In addition, the geoaccumulation indices for Cr, Cu, Ni, Zn, As, and Hg confirmed anthropogenic sources of accumulation of these metals in soils. Additionally, the potential ecological risk index indicated that Hg posed a considerable risk to the ecology of the area around the landfill. Sources of heavy metals in the study area were attributed to natural sources (22.10%), agricultural activities (27.65%), landfill (31.35%), and transportation (18.89%). The continuous accumulation of heavy metals and health risk for humans suggests the need to continuously monitor of heavy metal content and migration around the landfill. This study provides a reference for local authorities in the study area.

重金属污染是城市固体垃圾填埋场的负面影响。垃圾填埋场周围的多种污染输送途径（包括渗滤液、径流和废气）和复杂共存的潜在污染源（如农业活动）需要结合不同的污染评估方法和源识别工具来解决污染分布和潜在污染问题。风险。在本研究中，八种重金属（铬（Cr）、铜（Cu）、镍（Ni）、铅（Pb）、锌（Zn）、砷（As）、镉（Cd）和汞（Hg）的分布） )) 在垃圾填埋场周围使用 60 个表土样品进行分析。生态风险评估表明，目前不存在生态风险。然而，根据健康风险评估，土壤中高浓度的 Cr 和 As 分别对研究区域的人类造成非致癌和致癌风险。此外，Cr、Cu、Ni、Zn、As 和 Hg 的地积累指数证实了这些金属在土壤中的人为积累来源。此外，潜在生态风险指数表明，汞对垃圾填埋场周边地区的生态构成了相当大的风险。研究区重金属的来源主要为自然源（22.10%）、农业活动（27.65%）、垃圾填埋场（31.35%）和交通（18.89%）。重金属的持续积累和人类健康风险表明需要持续监测垃圾填埋场周围的重金属含量和迁移。本研究可为研究区的地方政府提供参考。
