摘　　要：酞酸酯是土壤、水体、大气和沉积物等多环境介质中广泛分布的典型有机污染物,具有致畸、致癌、致突变"三致"毒性效应和内分泌干扰作用,威胁生态安全与人体健康。本文围绕我国设施蔬菜地的酞酸酯污染问题,概括了土壤-植物系统中酞酸酯污染分布特征,详述了国内外有关土壤中酞酸酯土-气/土-水/土-植等多界面迁移作用过程、典型设施蔬菜体内酞酸酯代谢和微生物降解转化过程与作用机制,比较分析了土壤中酞酸酯的生物有效性、在不同生理生化和植物组织水平上的毒性效应及对微生物生态功能的影响,总结了土壤中酞酸酯污染防控与修复的关键技术方法和农艺调控举措,并就土壤中酞酸酯迁移转化和生物有效性等的研究趋势进行了展望,以期为酞酸酯的污染评估和有效防控、降低酞酸酯污染生态风险和保障农产品安全提供科学依据。Phthalic acid esters（PAEs） are typical organic pollutants widely distributed in various environments,including soil, water, atmosphere and sediments, etc. Meanwhile, PAEs are well known to have endocrine disruption and toxicological effects of teratogenicity, carcinogenicity and mutagenicity, causing great threats to human health and ecosystem security. In this paper, we review the distribution characteristics of PAEs pollution in the soil-plant system,summarize the multi-interfacial（soil-air, soil-water and soil-plant） migration and transformation of PAEs in the soil and its function mechanism, the in vivo metabolism, microbial degradation process and interactive mechanisms of PAEs,compared and analyzed the bioavailability of PAEs in soils, the toxicological effects at different physiological-biochemical and tissues levels, and the effects of PAEs on microbial ecological function, elaborated the pivotal techniques for preventing and control of PAEs pollution and novel strategies of agronomic regulation, and proposed the research trends on migration and transformation of PAEs in soils and associated bioavailability problems.
