The widespread distribution of phthalates (PAEs) in agricultural soils is increasing drastically; however, the environmental occurrence and potential risk of PAEs in agricultural systems remain largely unreviewed. In this study, the occurrence, sources, ecotoxicity, exposure risks, and control measures of PAEs contaminants in agricultural soils are summarized, and it is concluded that PAEs have been widely detected and persist in the soil at concentrations ranging from a few μg/kg to tens of mg/kg, with spatial and vertical variations in China. Agrochemicals and atmospheric deposition have largely contributed to the elevated contamination status of PAEs in soils. In addition, PAEs cause multi-level hazards to soil organisms (survival, oxidative damage, genetic and molecular levels, etc.) and further disrupt the normal ecological functions of soil. The health hazards of PAEs to humans are mainly generated through dietary and non-dietary pathways, and children may be at a higher risk of exposure than adults. Improving the soil microenvironment and promoting biochemical reactions and metabolic processes of PAEs are the main mechanisms for mitigating contamination. Based on these reviews, this study provides a valuable framework for determining future study objectives to reveal environmental risks and reduce the resistance control of PAEs in agricultural soils.
邻苯二甲酸酯（PAEs）在农业土壤中的广泛分布正在急剧增加；然而，农业系统中 PAEs 的环境出现和潜在风险在很大程度上仍未得到审查。在这项研究中，总结了农业土壤中 PAEs 污染物的发生、来源、生态毒性、暴露风险和控制措施，结论是 PAEs 已被广泛检测到并在土壤中持续存在，浓度范围从几μg/kg 到几十mg/kg，在中国具有空间和垂直变化。农药和大气沉降在很大程度上导致了土壤中 PAEs 污染状况的升高。此外，PAEs 对土壤生物（生存、氧化损伤、遗传和分子水平等）造成多层次危害，并进一步破坏土壤的正常生态功能。PAEs 对人类的健康危害主要通过饮食和非饮食途径产生，儿童比成年人更容易接触到这些危害。改善土壤微环境和促进 PAEs 的生化反应和代谢过程是减轻污染的主要机制。基于这些综述，本研究为确定未来的研究目标提供了一个有价值的框架，以揭示环境风险并降低农业土壤中 PAEs 的抗性控制。
