Research Progress on the Impact of Microplastics on Agricultural Environment and Crops
Microplastic pollution has emerged as a global concern on account of the generation of vast amounts of non-biode-gradable plastic waste and products.As a result,microplastics have drawn extensive research attention,and there has been a lot of findings in this regard.In agricultural systems,microplastics not only have impact on the soil environment,but can also adversely affect plants.The negative effects of microplastics in agro-ecosystems are related to food security and human health,and a large number of studies have been done on the toxicity mechanism of microplastics and their effects on the physiology,biochemistry and development of various crops.This review systematically summarized and sorted out the char-acteristics and transmission routes of microplastics in agricultural environment,as well as the effects of composite pollution on agricultural environment and crop growth and development.It also summarized the mechanism of toxic effects of different properties of microplastics on crops,in order to provide theoretical basis and scientific support for ecological risk assess-ment,control and prevention.
