Phytoaccumulation of Micro- and Nanoplastics: Root Uptake
AI summary Read the abstract
Researchers examined how plants absorb micro- and nanoplastics through their roots, finding that these particles travel through soil and water systems to enter the food chain via crops, raising concerns about human exposure through plant-based foods.
Accumulation of microplastics and nanoplastics in the environment accounts for some of the ecological and health issues in plants. They move in the environment through ocean current and atmospheric circulation, leading to their abundant accumulation in the major...

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.
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.
Micro- and Nanoplastics on Plant Functionalities
AI summary Read the abstract
Researchers reviewed how micro- and nanoplastics affect plant physiology and function — including germination, root growth, photosynthesis, and nutrient uptake — across a range of crop and wild plant species. Plant uptake of plastic particles is a key mechanism by which microplastic contamination moves from soil into the human food supply, making these effects central to understanding dietary exposure risks.
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.
Micro- and Nanoplastics: Impact on Crop Plants and Agricultural Practices
AI summary Read the abstract
Researchers reviewed the growing contamination of agricultural soil and water by micro- and nanoplastics, finding that plastic debris disrupts soil structure, inhibits seed germination, reduces crop yields, and introduces toxic additives into the food production chain, with the COVID-19 pandemic accelerating plastic waste generation and agricultural exposure.
