近年来，农业系统中地膜覆盖过程中邻苯二甲酸酯（PAEs）的释放和污染受到了广泛关注。本文在综合文献的基础上，系统评价了邻苯二甲酸酯的存在、释放、迁移和转化，并讨论了潜在的环境风险。尽管最近发现的∑6PAEs含量较低，但PAEs普遍存在于聚乙烯和可生物降解地膜中，邻苯二甲酸二（2-乙基己基）酯（DEHP）和邻苯二甲酸二正丁酯（DBP）是最丰富的同系物。使用塑料地膜会增加土壤中邻苯二甲酸酯类化合物的潜在污染。PAEs的扩散系数、PAEs与塑料的结构以及环境条件是影响PAEs从塑料中扩散潜力的因素。PAEs的潜在环境风险来自地膜覆盖，涉及土壤污染，空气挥发和食用植物的吸收。邻苯二甲酸酯类化合物的环境风险与其所处的环境和化学分子结构有关。研究结果和讨论表明，塑料地膜本身不存在PAEs污染风险，但其与同期农业实践的相互作用可能导致农业环境危害并降低食用植物的质量。因此，应考虑进一步跨学科研究和综合评估的来源和影响的PAE污染覆盖农艺系统，以协助产品的改进和危害预防。
The release and contamination of phthalate acid esters (PAEs) arrived from plastic film mulching in agricultural systems has been received great concern recently. Based on a comprehensive review of published literatures, this study systematically evaluated the presence, release, migration, and transformation of PAEs and discussed potential environmental risk. Even though a lower ∑6PAEs content observed recently, the PAEs are ubiquitously detected in both polyethylene and biodegradable mulch films with di(2-ethylhexyl) phthalate (DEHP) and di-n-butyl phthalate (DBP) are the most abundant congeners. The use of plastic mulch film will increase the potential soil contamination of PAEs. The diffusivity of PAEs, the structures of PAEs and plastics, and the environmental conditions are factors influencing the leachability potential of PAEs from plastics. Potential environmental risk of PAEs arrived from plastic film mulching involved of soil contamination, air volatilization, and uptake by edible plants. The surrounding environment and the chemical molecular structures of PAEs will influence their environmental risks. The findings and discussion of the study indicated that there was no PAEs contamination risks of plastic mulch film itself but its interaction with concurrent agricultural practices may result in an agricultural environmental hazard and reduce the quality of edible plants. Therefore, further interdisciplinary research and integrated assessment of the sources and impacts of PAE contamination in mulching agronomic systems should be considered to assist in product improvement and hazard prevention.
