Emerging contaminants (ECs) are gaining attention due to their prevalence and potential negative impacts on the environment and human health. This paper provides a comprehensive review of the status and trends of soil pollution caused by ECs, focusing on their sources, migration pathways, and environmental implications. Significant ECs, including plastics, synthetic polymers, pharmaceuticals, personal care products, plasticizers, and flame retardants, are identified due to their widespread use and toxicity. Their presence in soil is attributed to agricultural activities, urban waste, and wastewater irrigation. The review explores both horizontal and vertical migration pathways, with factors such as soil type, organic matter content, and moisture levels influencing their distribution. Understanding the behavior of ECs in soil is critical to mitigating their long-term risks and developing effective soil remediation strategies. The paper also examines the advantages and disadvantages of in situ and ex situ treatment approaches for ECs, highlighting optimal physical, chemical, and biological treatment conditions. These findings provide a fundamental basis for addressing the challenges and governance of soil pollution induced by ECs.
新兴污染物（ECs）因其普遍存在以及对环境和人类健康的潜在负面影响而受到关注。本文全面综述了 ECs 引起的土壤污染的现状和趋势，重点关注其来源、迁移途径和环境影响。由于广泛使用和毒性，包括塑料、合成聚合物、药品、个人护理产品、增塑剂和阻燃剂在内的一些显著的 ECs 被确定为主要污染物。它们在土壤中的存在归因于农业活动、城市废物和废水灌溉。本综述探讨了水平和垂直迁移途径，土壤类型、有机质含量和水分水平等因素影响着它们的分布。了解 ECs 在土壤中的行为对于减轻其长期风险和制定有效的土壤修复策略至关重要。本文还考察了原位和异位处理方法在 ECs 处理方面的优缺点，强调了最优的物理、化学和生物处理条件。这些发现为应对 ECs 引起的土壤污染的挑战和治理提供了基础。
