2021年乌鲁木齐市农村土壤重金属健康风险评价

Evaluation of Health Risk from the Rural Soil Heavy Metal in Urumqi City in 2021

  • 摘要: 以乌鲁木齐市种植型、商业旅游型、牧业型和生态型等4种类型的7个典型村庄的土壤为研究对象,共设置了35个监测点位,测定分析了农村土壤的重金属污染指标,采用达标评价、内梅罗污染指数和健康风险评估模型对农田土壤重金属分布特征、环境质量和健康风险进行评估,监测结果显示:乌鲁木齐市农村土壤环境质量均处于清洁(安全)水平;R手-口R皮肤R呼吸RT致癌风险数量级均处于安全区间10-6~10-4,不存在致癌风险;每种重金属元素的非致癌风险HQ和8种重金属元素共同产生的非致癌总风险HI均未超过1,不存在对居民群众的非致癌风险。

     

    Abstract: Taking the soil of 7 typical villages in Urumqi, including planting, commercial tourism, animal husbandry and ecological type, as the research object, a total of 35 monitoring points were set up, and the heavy metal pollution indicators of rural soil were measured and analyzed. The standard evaluation, Nemeiro pollution index and health risk assessment model were used to evaluate the distribution characteristics of farmland soil heavy metals, environmental quality and health risks. The monitoring results showed that the environmental quality of rural soil in Urumqi is at a clean(safe) level; R-hand-The carcinogenic risk of mouth, R skin, R breathing, and RT are all within the safe range of 10-6~10-4, and there is no carcinogenic risk; the non-carcinogenic risk of each heavy metal element HQ and the total non-carcinogenic total of 8 heavy metal elements The risk HI does not exceed 1, and there is no non-carcinogenic risk to the residents.
