随着快速城市化和工业化的进行，固体废物的产生每天都在增加，已成为国际社会关注的问题。垃圾填埋场的渗滤液泄漏会污染土壤，并有潜在的危害人体健康。本文采用电感耦合等离子体-光发射光谱分析法对土壤样品中的金属（Ba、Cd、Pb、Hg、Cu、Cr和Mn）和类金属元素（As）的组成进行评估和分析。得出的Cr、Mn、Cu、As、Ba、Cd、Pb和Hg结果来自于San Joaquin 土壤的CRM（认证参考物质，SRM 2709a），以回收率百分比的形式进行评估和报告，其范围为97.6-102.9%，显示出出色的萃取效率。除了铜，欧盟在土壤中设定的允许限值为50-140 mg/kg之外，所有金属的平均含量都在WHO、欧洲联盟（EU）和美国EPA规定的可允许限值范围内。 受Hg（PERI = 100）和Cd（PERI = 145.50）污染的土壤具有显著的生态风险。污染负荷指数（PLI）值大于1，而污染程度（Cdeg）值小于32，说明土壤受到金属和类金属元素的污染和相当的污染。以土壤的平均日剂量（ADD）为衡量标准，儿童所接受的所有金属的剂量最高（ADDing = 1.315 × 10-7 - 2.470 × 10-3，ADDderm = 9.939 × 10-7 - 5.292 × 10-11），而成人的ADDing（1.409 × 10-8 - 2.646 × 10-4）较大。除了Ba外，所有金属在儿童和成人中的危害系数（HQ）趋势均为HQing > HQderm > HQinh。处于癌症风险较低的儿童通过多种途径暴露于土壤中，Cr的终身癌症风险（LCR）为2.039×10-4。 © 2023. 作者（们）独家授予Springer Nature B.V.专用许可。

The generation of solid waste is increasing with each passing day due to rapid urbanization and industrialization and has become a matter of concern for the international community. Leachate leakages from landfills pollute the soil and can potentially harm the human health. In this paper, inductively coupled plasma-optical emission spectrometric studies were employed to assess and analyze the composition of metals (Ba, Cd, Pb, Hg, Cu, Cr and Mn) and metalloid (As) in soil samples. Results of Cr, Mn, Cu, As, Ba, Cd, Pb and Hg from CRM (certified reference material, SRM 2709a) of San Joaquin soil were evaluated and reported in terms of percent recoveries which were in the range of 97.6-102.9% and show outstanding extraction efficiency. Other than copper, where the permitted limit set by the EU is specified as 50-140 mg/kg in soil, the average amount of all the metals in soil was found within the permissible limits provided by WHO, the European Community (EU) and US EPA. Soil contaminated with Hg (PERI = 100) and Cd (PERI = 145.50) posed an ecological risk significantly. Pollution load index (PLI) value is greater than 1, while degree of contamination (Cdeg) value is less than 32 which indicated that the soil is polluted and considerably contaminated with metals and metalloid, respectively. In terms of the average daily dosage (ADD) of soil, children received the highest doses of all metals (ADDing = 1.315 × 10-7 - 2.470 × 10-3 and ADDderm = 9.939 × 10-7 - 5.292 × 10-11), whereas ADDing (1.409 × 10-8 - 2.646 × 10-4) was found greater in adults. For all metals except for Ba, the hazard quotient (HQ) trend in both children and adults was observed to be HQing > HQderm > HQinh of soil. Children who are at the lower edge of cancer risk had a lifetime cancer risk (LCR) of 2.039 × 10-4 for Cr from various paths of soil exposure.© 2023.
