纳米二氧化钛对植物的毒性效应研究进展
Research Progress in the Toxic Effects of Titanium Dioxide Nanoparticles on Plants
摘要
Abstract
Since the 21st century,the development and application of nanomaterials have accelerated and expanded significantly,with nano titanium dioxide(TiO2 NPs)emerging as the most prolific nano metal oxide in terms of annual production.Its widespread use has not only facilitated numerous advancements but has also raised concerns regarding its toxic effects on plants.A systematic review of the mechanisms and causes underlying the toxicity of TiO2 NPs is therefore both critical and timely.This paper summarizes the fundamental pathways through which TiO2 NPs exert toxicity on plants and analyzes their toxic effects,both individually and in combination with other pollutants,across various dimensions including visible growth,physiology,biochemistry and molecular levels.Furthermore,this paper prospected the future research directions aimed at deepening our understanding of toxicity mechanisms,expanding the research scope and fostering innovation and application of nanotechnology.These efforts are intended to enhance our ability to assess environmental risks associated with nanomaterials and provide a scientific foundation for the sustainable application of nanomaterials in agriculture and environmental fields.关键词
