Micro/nanoplastics: Critical review of their impacts on plants, interactions with other contaminants (antibiotics, heavy metals, and polycyclic aromatic hydrocarbons), and management strategies
AI summary Read the abstract
This review examines how micro- and nanoplastics harm plants, both alone and in combination with other pollutants like antibiotics, heavy metals, and hydrocarbons. The combined exposure often worsens the damage, including inhibited growth, reduced seed germination, and genetic toxicity. The review also explores strategies to reduce this plant damage, which matters for food safety since contaminated crops are a route for microplastics to reach humans.
Microplastic/nanoplastics (MPs/NPs) contamination is not only emerging threat to the agricultural system but also constitute global hazard to the environment worldwide. Recent review articles have addressed the environmental distribution of MPs/NPs and their single-exposure phytotoxicity in various plant species. However, the mechanisms of MPs/NPs-induced phytotoxicity in conjunction with that of other contaminants remain unknown, and there is a need for strategies to ameliorate such phytotoxicity. To address this, we comprehensively review the sources of MPs/NPs, their uptake by and effects on various plant species, and their phytotoxicity in conjunction with antibiotics, heavy metals, polycyclic aromatic hydrocarbons (PAHs), and other toxicants. We examine mechanisms to ameliorate MP/NP-induced phytotoxicity, including the use of phytohormones, biochar, and other plant-growth regulators. We discuss the effects of MPs/NPs -induced phytotoxicity in terms of its ability to inhibit plant growth and photosynthesis, disrupt nutrient metabolism, inhibit seed germination, promote oxidative stress, alter the antioxidant defense system, and induce genotoxicity. This review summarizes the novel strategies for mitigating MPs/NPs phytotoxicity, presents recent advances, and highlights research gaps, providing a foundation for future studies aimed at overcoming the emerging problem of MPs/NPs phytotoxicity in edible crops.

Effects of nanoplastics and compound pollutants containing nanoplastics on plants, microorganisms and rhizosphere systems: A review
AI summary Read the abstract
This review summarizes how nanoplastics, the tiniest plastic particles, affect plants, soil microorganisms, and the root zone where they interact. Nanoplastics can disrupt photosynthesis, alter gene activity, and reduce microbial diversity, and their harmful effects get worse when they combine with heavy metals or other pollutants. Since plant roots are a key pathway for nanoplastics to enter the food chain, these effects could ultimately impact the safety and nutritional quality of the food we eat.
Coupling polyethylene microplastics with other pollutants: Exploring their combined effects on plant health and technologies for mitigating toxicity
AI summary Read the abstract
This review summarizes how polyethylene microplastics interact with other common soil pollutants like heavy metals and antibiotics in agricultural fields. Microplastics can absorb these pollutants and carry them into plants, making the combined exposure more harmful than either pollutant alone. The findings raise concerns about the safety of crops grown in microplastic-contaminated soil.
Looking into the effects of co-contamination by micro(nano)plastics in the presence of other pollutants on irrigated edible plants
AI summary Read the abstract
This review examines the combined effects of micro- and nanoplastics with other pollutants found in treated wastewater used for crop irrigation. Researchers analyzed 19 studies and found that the joint exposure to plastics and contaminants like heavy metals or pesticides often produced different toxicity outcomes than either pollutant alone. The findings suggest that using reclaimed wastewater for irrigation may expose food crops to complex mixtures of pollutants whose combined effects are still poorly understood.
Recent Advances on Multilevel Effects of Micro(Nano)Plastics and Coexisting Pollutants on Terrestrial Soil-Plants System
AI summary Read the abstract
This review systematically summarizes how micro- and nanoplastics, alone and combined with co-existing pollutants, affect soil properties and terrestrial plants at multiple biological levels. Researchers found that microplastics can serve as carriers for heavy metals, organic contaminants, and biological pollutants, with their specific impacts depending on polymer type, size, shape, and concentration. Evidence indicates that plants can take up and transport micro- and nanoplastics, leading to effects on growth, metabolism, and even DNA damage.
Micro (nano) plastic pollution: The ecological influence on soil-plant system and human health.
AI summary Read the abstract
This review examines how micro- and nanoplastics affect soil health, plant growth, and food quality, finding that these particles accumulate in plant root systems and can reduce crop yields and alter nutritional content. Since contaminated soil and water are increasingly delivering microplastics to food crops, these findings are directly relevant to agricultural food safety.
