The aim of this article is to review and present the state of the arte about the status of toxic elements (TEs) in soils and assess the potential risk using single and total complex pollution indices in a global scale. We compiled, integrated, and analyzed soil TE pollution data over almost a decade through key maps, which have not been reviewed up to date. All the in-situ and ex-situ remediation treatments have been also reviewed, illustrated, and compared, for the first time. The future perspectives have been discussed and summarized. This review demonstrates that the cornerstone maps and integrated information provide reliable geographical coordinates and inclusive information on TEs pollution, particularly in China. In-situ treatment approaches for TEs polluted soils are more cost-effective and applicable than ex-situ treatment trials. Selecting a feasible remediation strategy should to take the extent of contamination, treatment objectives, site characteristics, cost-efficiency, and public suitability into account. The summarized findings in this review may help to develop innovative and applicable methods for assessing the global soil pollution by TEs. Also, these findings may help to develop innovative, applicable, and feasibly economic methods for sustainable management of TEs contaminated soils to mitigate the environmental and human health risk.
本文旨在综述和呈现当前全球范围内土壤中毒素（TEs）的状况，并利用单一和综合的复杂污染指数评估其潜在风险。我们通过关键图汇集、整合和分析了近十年来的土壤 TE 污染数据，这些数据尚未进行过最新的综述。此外，我们还首次对所有原位和异位修复处理进行了综述、说明和比较。本文还讨论并总结了未来展望。本综述表明，基础图和综合信息为 TE 污染提供了可靠的地理坐标和全面的信息，特别是在中国。与异位处理试验相比，原位处理方法更具成本效益，更适用于 TEs 污染土壤。选择可行的修复策略时，应考虑污染程度、处理目标、场地特征、成本效益和公众适宜性等因素。本文的总结发现可能有助于开发用于评估全球土壤 TE 污染的创新和适用方法。此外，这些发现还有助于开发创新、适用和在经济上可行的方法，以可持续管理 TEs 污染土壤，减轻环境和人类健康风险。
