摘要: 人工纳米颗粒(engineered nanoparticles,ENPs)在被广泛应用的同时,其潜在的环境风险和对健康的影响引起国内外的广泛重视。植物是人们的主要食物来源,ENPs可能被植物吸收并累积在可食部分,随食物链进入人体而引起健康风险。因此,ENPs的植物毒性及其在植物中的吸收和累积受到越来越多的关注。总结了ENPs的植物毒性及植物对ENPs的吸收、运输和累积,讨论了可能的致毒机制、影响其毒性的因素以及植物的解毒机制,并对未来应该注重开展的研究进行了展望。

Abstract: With the increasing application, potential environmental risk and health safety of engineered nanoparticles (ENPs) have attracted wide attention. Plants play an important role in human food resources. ENPs can be taken up and accumulated in edible parts, then enter human bodies via food chain to cause potential health risk. Therefore, phytotoxicity of ENPs and their uptake and accumulation in plants have attracted more attention. In this paper, the current knowledge on the phytotoxicity and the uptake, transport and accumulation of ENPs in plants was summarized. The possible toxicity mechanisms of ENPs and their contributing factors, and the detoxification mechanisms of plants were discussed. On these bases, some future research directions in this field were proposed.
