ClearMeta-analysis reveals the combined effects of microplastics and heavy metal on plants
A meta-analysis of 57 studies found that the combined toxicity of microplastics and heavy metals on plants is driven primarily by the heavy metals, while microplastics mainly interact by inducing oxidative stress damage. Microplastic biodegradation emerged as a core factor influencing heavy metal accumulation in plants, with culture environment, heavy metal type, exposure duration, and microplastic concentration and size all playing roles.
Morphological, physiological, and molecular responses of Perilla frutescens to copper stress alleviated by PVC microplastics
Researchers discovered that low concentrations of PVC microplastics can actually reduce the harmful effects of copper on perilla plants, an important crop. The microplastics appeared to help by improving cell membrane function, suppressing stress hormones, and adjusting fat metabolism pathways. While this does not mean microplastics are beneficial overall, the study reveals surprisingly complex interactions between plastic pollution and heavy metals in agricultural environments.
Impact of Biotic/Abiotic Stress Factors on Plant Specialized Metabolites
Not relevant to microplastics — this paper appears to examine how biotic and abiotic stress factors influence specialized metabolite production in plants; the available abstract is incomplete but contains no indication of microplastic relevance.
Polypropylene Microplastics Bidirectionally Modulate Copper Toxicity in Jasminum sambac by Rewiring Glutathione and Porphyrin‐Photosynthetic Networks
Researchers exposed jasmine plants to copper-spiked soil with varying levels of polypropylene microplastics and observed a non-linear, dose-dependent effect on copper toxicity. At intermediate microplastic levels, the plants showed reduced copper uptake and improved photosynthesis through coordinated adjustments in antioxidant and chlorophyll pathways. However, at higher microplastic concentrations, this protective effect disappeared as antioxidant defenses collapsed, suggesting microplastics can both buffer and worsen metal toxicity in soils depending on the dose.
Employing Phytoremediation Methods to Extract Heavy Metals from Polluted Soils
This paper is not directly about microplastics in the typical environmental exposure sense; it studies phytoremediation — using the Dodonaea plant to absorb heavy metals (zinc, nickel, cadmium) from contaminated soil — with no connection to plastic or microplastic pollution.
Detoxifying the heavy metals: a multipronged study of tolerance strategies against heavy metals toxicity in plants
This review looks at how plants deal with toxic heavy metals in their environment, covering strategies like blocking metal uptake, storing metals in safe compartments, and using special proteins to neutralize damage. While not directly about microplastics, it is relevant because microplastics can carry heavy metals into soil, making plant exposure worse. Understanding these plant defense mechanisms could help develop crops that are more resilient to contaminated environments.
Polyploidy affects responses to Nickel in Ni-hyperaccumulating plants: Evidence from the model species Odontarrhena bertolonii (Brassicaceae)
This paper is not about microplastics; it studies whether polyploid plants (those with extra chromosome sets) accumulate more nickel than diploid plants when grown in metal-contaminated soils, with applications in phytoremediation.
Microplastics as emerging stressors in plants: biochemical and metabolic responses
This review examines how microplastics act as environmental stressors in plants, disrupting biochemical and metabolic processes including photosynthesis, antioxidant defenses, and nutrient uptake, with effects varying by polymer type, particle size, and concentration.
Microbial synergies in phytoremediation: A comprehensive review
Not relevant to microplastics — this is a review of how soil microorganisms (bacteria, fungi) assist plants in removing pollutants like heavy metals and hydrocarbons through phytoremediation; while the study addresses environmental contamination broadly, it does not examine microplastic pollution or its effects.
Effects of microplastics and heavy metal stress on the growth and physiological characteristics of pioneer plant Avicennia marina
Researchers studied how mangrove plants respond to combined pollution from microplastics and heavy metals at levels found in the environment. The combination caused more oxidative stress and growth problems than either pollutant alone, disrupting the plants' defense systems. Since mangroves protect coastlines and filter water for coastal communities, damage to these ecosystems from microplastic-heavy metal pollution could have indirect effects on human well-being.
Environmental microplastic interact with heavy metal in polluted soil from mine site in the North of Tunisia: Effects on heavy metal accumulation, growth, photosynthetic activities, and biochemical responses of alfalfa plants (Medicago saliva L.)
This study tested how microplastics interact with heavy metals in contaminated mine soil and affect alfalfa plant growth in Tunisia. Adding microplastics to polluted soil increased the amount of heavy metals absorbed by the plants and triggered oxidative stress, causing more damage than either pollutant alone. This is concerning for human health because crops grown in microplastic-contaminated soil near mining areas may accumulate higher levels of toxic metals.
Nutrient Metabolism Pathways Analysis and Key Candidate Genes Identification Corresponding to Cadmium Stress in Buckwheat through Multiomics Analysis
This study used transcriptomic and metabolomic analysis to investigate how buckwheat responds to cadmium stress at the molecular level, identifying key metabolic pathways affected by the heavy metal. It is not about microplastics and is not relevant to microplastic research.
Understanding the possible cellular responses in plants under micro(nano)-plastic (MNPs): Balancing the structural harmony with functions.
This review summarizes current understanding of how micro- and nano-plastics affect plant physiology, covering uptake pathways, effects on cell walls and chloroplasts, and responses to oxidative stress. The findings highlight that plants are exposed to and affected by microplastics through both soil and aerial routes.
Assessing stress responses in potherb mustard (Brassica juncea var. multiceps) exposed to a synergy of microplastics and cadmium: Insights from physiology, oxidative damage, and metabolomics
Researchers found that microplastics in soil increased the amount of cadmium, a toxic heavy metal, that mustard green plants absorbed, while also reducing crop yields and photosynthesis. Higher concentrations of microplastics made more cadmium available in the soil, leading to greater accumulation of the metal in the plants. This raises food safety concerns because vegetables grown in microplastic-contaminated soil could contain higher levels of toxic metals that are harmful to human health.

Effects of the co-exposure of microplastic/nanoplastic and heavy metal on plants: Using CiteSpace, meta-analysis, and machine learning
This meta-analysis found that co-exposure to micro/nanoplastics and heavy metals produces stronger toxic effects on plants than heavy metal exposure alone, with toxicity increasing at higher concentrations, longer durations, and with nanoparticles. Notably, polyolefin plastics partially reduced plant toxicity from heavy metals, while modified polystyrene and biodegradable polymers worsened it.

Researchers used physiological, transcriptomic, and metabolic analysis to assess the effects of nano/microplastics on tea plants, finding impaired photosynthesis, oxidative stress, and disrupted metabolic pathways at environmentally relevant concentrations. The study highlights risks to tea crop safety and quality from plastic pollution in agricultural soils.
Micro (nano) plastics uptake, toxicity and detoxification in plants: Challenges and prospects
This review examines how micro and nanoplastics are taken up by plants, covering their toxic effects on growth and gene expression as well as potential detoxification strategies. Smaller nanoplastics can penetrate plant cell walls and accumulate in tissues, causing oxidative stress and genetic damage. The findings are important for human health because contaminated crops could transfer microplastics directly into the food supply.
