This study examined how nanoplastics affect rice plant growth, finding that the tiny particles were absorbed by roots and entered plant cells. Nanoplastic exposure reduced important enzyme activity and protein levels in roots, disrupting normal plant metabolism. The presence of iron plaque and humic acid in the soil changed how much nanoplastic the plants took up, suggesting that real-world soil conditions play a key role in how crops are affected.
Mechanistic insight into the intensification of arsenic toxicity to rice (Oryza sativa L.) by nanoplastic: Phytohormone and glutathione metabolism modulation
Nanoplastics at environmentally realistic levels did not harm rice plants on their own, but when combined with arsenic they made arsenic toxicity significantly worse, reducing plant growth by up to 23%. The nanoplastics increased arsenic uptake by disrupting plant hormones and weakening the plant's natural detoxification systems. This is concerning because rice is a staple food for billions of people, and agricultural soils increasingly contain both nanoplastics and heavy metals.
Fate 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.
Phosphorus fertiliser application mitigates the negative effects of microplastic on soil microbes and rice growth
Researchers found that adding phosphorus fertilizer to soil contaminated with microplastics helped counteract the negative effects of the plastics on rice growth and soil microbial communities. The microplastics alone disrupted bacterial interactions and suppressed plant development, but fertilizer application restored much of the lost productivity. The study offers practical guidance for managing agricultural soils in areas affected by microplastic pollution.
