Assessing toxicity of photoaged polystyrene microplastics to growth performance of rice (Oryza sativa)

Physiological and Biochemical Effects of Polystyrene Micro/Nano Plastics on Arabidopsis Thaliana

Responses of rice (Oryza sativa L.) plant growth, grain yield and quality, and soil properties to the microplastic occurrence in paddy soil

AI summary · Read the abstract

Researchers found that microplastics in paddy soil had complex effects on rice crops — some types actually increased grain yield by up to 30%, while also altering soil chemistry, nutrient availability, and amino acid composition in the grain. The findings suggest that microplastic contamination in agricultural soils may affect not just plant health but also the nutritional quality of food crops.

Effects of microplastics on growth and metabolism of rice (Oryza sativa L.)

Researchers found that polystyrene and polyvinyl chloride microplastics inhibited rice growth and disrupted ionic homeostasis and antioxidant metabolism in a dose-dependent manner, with PVC microplastics causing more severe effects than polystyrene.

Advances in Physiological and Ecological Effects of Microplastic on Crop

AI summary · Read the abstract

Researchers reviewed how microplastics accumulate in crops — entering through roots and leaves and reaching edible parts — and found they reduce germination, inhibit photosynthesis, and lower crop yields, raising concerns about plastic contamination in the food we eat.

Impact of Microplastics and Nanoplastics on Plant Health and Development

AI summary · Read the abstract

Researchers review the emerging evidence on how microplastics accumulate in agricultural soils and affect plant health and development, highlighting that while aquatic impacts are well documented, the effects on terrestrial food crops and soil-plant systems remain poorly understood.
