ClearFate of nano/microplastics and associated toxic pollutants in paddy ecosystems: Current knowledge and future perspectives
Researchers reviewed how micro- and nanoplastics enter rice paddies through irrigation, mulch films, and atmospheric deposition, then harm soil health and rice plant growth by disrupting nutrient cycles and increasing oxidative stress. Their findings are especially significant because rice feeds more than half the world's population, yet research on plastic contamination in paddy systems remains very limited.
