| 中文摘要: |
| 随着农业集约化发展，农田土壤中新污染物（ECs）的输入与累积日益加剧。新污染物常以微观、痕量或转化产物形式滞留于土壤，并伴随多来源和效应耦合特征，对生态系统和人体健康构成潜在威胁和“看不见的危机”。本文系统综述了农田中持久性有机污染物、微塑料、内分泌干扰物和抗生素四类新污染物的来源、关键输入途径，并重点阐述了新污染物在农田中的吸附-解吸、迁移、植物吸收与降解等环境行为。并基于此，探讨了新污染物源头控制、原位修复及农艺调控的综合治理策略。论文提出未来需加强新污染物在复合污染情境下的环境行为、毒性效应和风险评估机制研究，推动高效低风险的修复技术发展，为农业可持续与食品安全保障提供理论依据。 |

| With the development of agricultural intensification, inputs and accumulation of emerging contaminants（ECs）in agricultural soils have increased markedly. Because these contaminants often persist in soil matrices as microscale particles, trace level residues, or transformation products, and are shaped by multisource inputs and coupled effects, they pose potential threats and“invisible crisis”to ecosystems and human health. This manuscript systematically reviewed the key sources and input pathways of four kinds emerging pollutants in farmland, including persistent organic pollutants, microplastics, endocrine disruptors and antibiotics, and focused on the environmental behaviors of ECs in farmland, such as adsorption-desorption, migration and transformation, plant absorption, and degradation. Based on this, the comprehensive management strategies of source control, remediation and agronomic regulation of ECs were discussed. In the future, it is recommended to strengthen research on the environmental behavior, toxic effects, and risk assessment mechanisms of ECs under complex contamination scenarios, promote the development of high-efficiency and low-risk remediation technologies, and provide theoretical basis for agricultural sustainability and food safety assurance. |
