Abstract

Abstract: Microplastics were plastic particles with a size of smaller than 5 millimetres, which were abundant and persistent in soil, posing a serious global environmental problem. Microplastics entered the crop body through the roots or leaves and affected different stages of crop growth. The pathways of microplastics entering the crop body and the detection methods of microplastics in crops of existing research were summarized, and the effects of different microplastics on crop germination rate, biomass, photosynthesis, oxidative stress system, nutrients, gene expression, etc. were explored. It was found that the influence of microplastics on crops varied with the characteristics of microplastics, crop species and environmental factors. Under certain experimental conditions, microplastics had no effect or a positive effect on crops. However, more studies had shown that microplastics could inhibit crop growth and ultimately affect crop yield. Moreover, microplastics could be enriched upward through food chains and affect human health.

Key words: microplastics, crops, migration and enrichment, food chain, risk
