摘　　要：稻田砷污染一直是环境研究的重点问题,其会对人们健康造成直接威胁,因而引起社会广泛关注。由于砷和磷的化学性质相似,磷对土壤和水稻中砷的吸附、迁移和转化有较大影响,研究稻田系统砷和磷的迁移转化规律以及砷磷的互作关系有助于进一步了解磷循环影响水稻砷吸收机制。该文综述了稻田砷、磷的迁移转化的最新研究进展,阐明了磷-砷竞争吸附的动态平衡、磷对砷氧化还原反应的间接调控作用、磷对砷甲基化和挥发的双重作用、多元素相互作用的复杂性等方面,提出了利用磷调控砷污染稻田水稻砷吸收的展望,以期为加强砷污染稻田治理提供科学依据。Arsenic(As)contamination in rice paddy fields has emerged as a critical environmental issue,posing a direct threat to human health and drawing widespread public concerns.Owing to the chemical similarity of As and phosphorus(P),P has a considerable impact on the adsorption,migration,and transformation of As within the soil-rice system.Probing into the migration and transformation mechanisms of both As and P,as well as their interactions,is key to deciphering how the P cycle influences the As uptake of rice.This paper overviews the recent advances in studies on the migration and transformation of As and P in rice paddy fields,elaborating on the key factors such as the dynamic equilibrium of P-As competitive adsorption,the indirect role of P about regulating As redox reactions,its dual influence on As methylation and volatilization,and the complexity of multi-element interactions,and furthermore,looking forward the potentials of leverag-ing P to regulate As uptake of rice.Hopefully,this review could provide a scientific basis for scientific management of As-contaminated rice paddies.
