Plant Stress Management Mitigating Micro/Nano Plastics Pollution
AI summary Read the abstract
This review covers how microplastics and nanoplastics enter agricultural soils via mulching, compost, and atmospheric deposition, disrupt plant nutrient uptake and cause oxidative stress, and examines mitigation strategies including bioaugmentation, nanomaterials, and phytoremediation.
Abstract Microplastics (MPs) and nanoplastics (NPs) are pervasive environmental pollutants, originating from plastic fragmentation and manufacturing processes. They enter ecosystems via wastewater discharge and littering, posing risks to wildlife and human health. In agriculture, MNPs disrupt soil health and crop productivity. Understanding their behavior is crucial for mitigation. Plant responses include nutrient uptake disruption and oxidative stress. Mitigation strategies include bioaugmentation, nanomaterials, and phytoremediation. Biochar and mustard plants show promise in MNP capture. Case studies highlight successful applications in compost for agriculture, emphasizing the need for further research and standardized monitoring for sustainable practices.

Micro and nanoplastics pollution: Sources, distribution, uptake in plants, toxicological effects, and innovative remediation strategies for environmental sustainability
AI summary Read the abstract
This review examines how microplastics and nanoplastics enter plants through roots, disrupt growth and photosynthesis, and cause oxidative stress that reduces crop yields. Because these plastic particles can move through plant tissues and into edible parts, they represent a potential pathway for microplastics to enter the human food supply.
Effects of microplastics and nanoplastics on agricultural plants
AI summary Read the abstract
This review examines the effects of microplastics and nanoplastics on agricultural plants, covering sources such as plastic mulch films, sewage sludge, and irrigation water, along with uptake mechanisms and observed physiological impacts. Micro- and nanoplastics reduce soil water-holding capacity, inhibit plant growth, cause oxidative stress, and impair seed germination; the smallest particles can enter roots and translocate to shoots via the vascular system. The presence of plastics and their additive chemicals in edible plant tissues raises concerns for both agricultural productivity and food safety.
Research Progress on the Mechanisms of Terrestrial Plant Uptake, Transport, and Growth Inhibition Responses to Micro (nano) Plastics
AI summary Read the abstract
This review synthesizes current research on how terrestrial plants take up micro- and nanoplastics from contaminated soil, finding that particles can enter through roots, accumulate in plant tissues, block root function, and trigger oxidative damage that stunts growth. These pathways mean that food crops grown in microplastic-contaminated soils could expose humans to plastic particles through the diet, in addition to the harm caused to agricultural productivity.
