Summary

Researchers reviewed how micro- and nanoplastics accumulate in soil through agricultural mulch films, sewage irrigation, and landfill leaching, disrupting soil ecosystems and potentially entering the food chain. Because these particles are so small, they can travel into groundwater and be absorbed by crops, raising concerns about human dietary exposure.

Micro- and nano-plastics (MNPs) are tiny particles formed from the breakdown of plastic waste. They enter the soil through landfills, agricultural practices like mulching, and irrigation with sewage water and cause several environmental problems. The movement of...
