稀土纳米材料与植物相互作用研究进展

Research Progress on Interactions between Rare Earth Nanomaterials and Plants

稀土纳米材料被广泛使用,目前已大量进入环境,并可能对环境产生负面影响。植物是生态系统的基本组成部分,它与稀土纳米材料的相互作用应受到更为广泛的关注。稀土纳米材料被认为可进入植物体内,但途径尚存在争议;这类材料被认为具有植物毒性,但致毒机制尚不明确。稀土纳米材料还能产生代际效应、食物链传递过程等,关系着食品安全。就近年来植物吸收、迁移、转化稀土纳米材料进行了综述,同时评述了稀土纳米材料的植物毒性效应、代际效应及食物链传递机制。

Owing to the wide application of rare earth nanomaterials(RENMs), a large number of RENMs enter the environment, which probably has negative effects on the environment. Plants are fundamental components of an ecosystem. Therefore, the interactions between RENMs and plants should be of particularly concern. RENMs can be absorbed by plants, but the way for RENMs to enter plants is controversial. The RENMs can cause phytotoxicity, but the toxic mechanism is also controversial. The RENMs can initiate plants intergenerational effects and food transportation process. These effects of RENMs closely relate to food safety. This paper reviewed the recent research progress on the interactions between RENMs and plants. The absorption, transportation, speciation transformation of RENMs in plants, the plants toxicity, plants intergenerational effects, and food chain transfer effect of RENMs were discussed.
