摘　　要：农田新兴有机污染物可通过作物吸收进入食物链从而威胁人体健康,其中,离子型新兴有机污染物(ionic emerging organic pollutants,IEOPs)因挥发性较弱、极性强而具有更为复杂的环境行为,因此,了解作物对IEOPs的吸收转化过程及机制,对明确IEOPs在农田系统中的归趋具有重要意义。该文综述了作物对IEOPs的吸收转运过程,重点介绍了IEOPs自身理化性质与作物组成、转运蛋白、调控基因等因素对该吸收转运过程的影响;从器官、组织和亚细胞等不同水平分析了IEOPs在作物中的累积分布规律;介绍了IEOPs在作物体内的酶促转化机理;最后,从加强IEOPs吸收机理研究、完善预测模型和关注作物体内转化机制等方面对该研究领域进行展望。Emerging organic pollutants are taken up by crops,posing a threat to human health via the food chain.The fate of ionic emerging organic pollutants(IEOPs)is more complicated due to their lower volatility and higher polarity.An understanding of the mechanisms of uptake,distribution,and transformation of IEOPs in crops is important for uncovering the fate of IEOPs in farming systems.Here,the crop uptake and translocation processes of IEOPs are reviewed,with a focus on the effects of the physicochemical properties of IEOPs,crop composition,transporters,and controlling genes,etc.The accumulation and distribution patterns of IEOPs in crops are discussed at the organic,tissular,and subcellular levels.Meanwhile,the transformation mechanisms of IEOPs,including the pathways and enzymes involved,are presented.Finally,the directions for future research in this field,e.g.,strengthening research on the uptake mechanisms,improving the uptake prediction models,and focusing on in vivo plant transformation,are presented.
