Nano-microplastic and agro-ecosystems: a mini-review

Frontiers in Plant Science, 2023
Plastics’ unavoidable and rampant usage causes their trash to be extensively dispersed in the atmosphere and land due to its numerous characteristics. Because of extensive plastic usage and increased manufacturing, there is insufficient recycling and a large accumulation of microplastics (MPs) in the environment.
