Direct or indirect exposure to inorganic arsenic (iAs) in the forms of AsIII (arsenite) and AsV (arsenate) through consumption of As-contaminated food materials and drinking water leads to arsenic poisoning. Rice (Oryza sativa L.) plant potentially accumulates a high amount of iAs from paddy fields than any other cereal crops. This makes it to be a major source of iAs especially among the population that uses it as their dominant source of diet. The accumulation of As in human bodies poses a serious global health risk to the human population. Various conventional methods have been applied to reduce the arsenic accumulation in rice plant. However, the success rate of these techniques is low. Therefore, the development of efficient and effective methods aimed at lowering iAs toxicity is a very crucial public concern. With the current advancement in technology, new strategies aimed at addressing this concern are being developed and utilized in various parts of the world. In this review, we discuss the recent advances in the management of iAs in rice plants emphasizing the use of nanotechnology and biotechnology approaches. Also, the prospects and challenges facing these approaches are described.
直接或间接通过摄入受砷污染的食物和饮用水，接触无机砷（iAs）的三价砷（arsenite）和五价砷（arsenate）形式会导致砷中毒。水稻（Oryza sativa L.）植物从稻田中积累的 iAs 量比任何其他谷物作物都要高。这使得水稻成为 iAs 的主要来源，尤其是在那些将其作为主要饮食来源的人群中。砷在人体中的积累对全球人口的健康构成了严重威胁。人们已经应用了各种常规方法来减少水稻中的砷积累。然而，这些技术的成功率较低。因此，开发旨在降低 iAs 毒性的高效、有效的方法是一个非常关键的公众关注点。随着当前技术的进步，世界上许多地方都在开发和利用新的策略来解决这一问题。在这篇综述中，我们讨论了在水稻植物中管理 iAs 的最新进展，重点介绍了纳米技术和生物技术方法的应用。还描述了这些方法面临的前景和挑战。
