Uptake of Microplastics and Their Effects on Plants
AI summary Read the abstract
Researchers reviewed accumulating evidence on microplastic uptake by terrestrial plants, finding that particles smaller than 200 nm can enter root cells and translocate to shoots, potentially disrupting photosynthesis, nutrient uptake, and growth while opening a pathway for microplastics to enter the human food chain through crops.
Microplastics (MPs, 100 nm to 5 mm) may represent a risk to ecosystem and human health, and MP pollution has become a topic of global environmental concern. Despite many reports on the accumulation of MPs in aquatic species, research on terrestrial...

Microplastics in Plant Species: Impacts and Ecological Perspectives
AI summary Read the abstract
This analysis examined how microplastics affect plant physiology in terrestrial ecosystems, including uptake through roots, translocation into edible tissues, disruption of photosynthesis, and alteration of soil microbial communities that plants depend on. Because many staple crops can absorb and accumulate microplastics from contaminated soil and irrigation water, agricultural microplastic pollution translates directly into human dietary exposure through fruits, vegetables, and grains.
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.
Impact of Microplastics on Plant Growth
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.
Tracking the uptake of nanoplastics in plants
AI summary Read the abstract
Researchers developed a method to track the uptake and transport of plastic nanoparticles in crop plants, as reported in Nature Nanotechnology. The ability to trace nanoplastic movement through edible plants is critical for understanding how microplastics and nanoplastics enter the human food supply through agricultural pathways.
