微(纳米)塑料(MNPs)是日益受到关注的新兴污染物。虽然陆地环境中的MNPs已被广泛报道，但关于土壤-植物系统中的MNPs对人类食物的影响还没有得到系统的讨论。在这里，我们回顾了农业土壤和植物中的MNP污染。尽管丰度不同，但在全球农业土壤中都检测到了微塑料。MNPs可进一步被作物吸收，并对植物造成多种类型的不利影响，包括氧化胁迫和作物生物量下降。通过土壤-植物系统，MNP污染物可以进入人类食物链。我们目前的观点是，(微/纳米)塑料可以从土壤、植物转移到人类食品中，这对食品安全构成了潜在威胁。
Micro(nano)plastics (MNPs) are emerging contaminations of growing concern. Although MNPs in terrestrial environments were widely reported, yet MNPs in the soil-plant system have not been systematically discussed regarding to human food. Here, we review MNP contaminations in agricultural soils and plants. Despite abundance variations, microplastics have been globally detected in agricultural soils. MNPs can further be uptake by crops, and cause multiple types of adverse effects on plants including oxidative stress and the decrease of crop biomass. Through the soil-plant system, MNP contaminations can entry into human food chains. Our current opinion is that (micro/nano)plastics can be transferred from soils, plants to human food, which poses a potential threat to food safety.
