ClearSize-dependent effects of polystyrene micro- and nanoplastics on the quality of rice grains and the metabolism mechanism
Researchers found that tiny polystyrene plastic particles (under 100 nanometers) were absorbed by rice roots and traveled up into the grain, reducing protein content by up to 29%. The smallest particles weakened the plant's natural defenses by disrupting sugar metabolism. This means microplastics in soil could be silently lowering the nutritional quality of rice that people eat.

The study highlights significant concerns about nanoplastic contamination entering the food chain through agricultural crops.
Nanoplastics are taken up by lettuce and barley under realistic soil condition
Scientists found that tiny plastic particles called nanoplastics can be absorbed by lettuce and barley plants when grown in soil, even at low pollution levels similar to what's found in the environment.

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.
Response of rice (Oryza sativa L.) roots to nanoplastic treatment at seedling stage
Researchers exposed rice seedlings to polystyrene nanoplastics and found that the particles were taken up by the roots, aided by water-transporting proteins in the plant.

Polylactic acid microplastics have stronger positive effects on the qualitative traits of rice (Oryza sativa L.) than polyethylene microplastics: Evidence from a simulated field experiment
Researchers found that both polyethylene and biodegradable polylactic acid microplastics in soil affected the quality of rice grains by changing their mineral content, fatty acid profiles, and amino acid levels. Interestingly, PLA microplastics had some positive effects on grain yield and weight, while PE microplastics more significantly disrupted the nutritional composition.
