ClearHeavy Metals in Foliar Dust: Utilizing Ziziphus spina‐christi Leaves in Estimating Levels of Vehicular Pollution
Despite its title referencing heavy metals in foliar dust, this paper studies air pollution from vehicular traffic — not microplastic pollution. It examines metal accumulation on the leaves of Ziziphus spina-christi trees as a biomonitoring approach for road pollution and is not relevant to microplastics or human health.
Biomonitoramento dos efeitos genotóxicos relacionados à poluição atmosférica em ambientes de intenso tráfego de veículos: Contribuições para a vigilância em saúde ambiental de populações expostas
This paper is not about microplastics; it reports a biomonitoring study using the plant Tradescantia pallida to measure genotoxic effects of vehicle traffic air pollution at urban intersections in Brazil.
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.
Foliar retention of atmospheric microplastics: Influence of leaf surface properties and rainfall intensity
Researchers found that leaf surface properties and rainfall intensity significantly influence how much atmospheric microplastics are retained on plant foliage, with leaves near a landfill retaining up to 0.80 items/cm2 and autumn showing the highest seasonal accumulation across five common urban tree species.
The role of microplastic pollution in the modification of the physicochemical properties of arable soil and uptake of potential toxic elements by plants
Researchers conducted a series of studies analyzing how microplastic pollution modifies the physicochemical properties of arable soil and affects the uptake of potentially toxic heavy metals by plants, beginning with a comprehensive literature review of microplastic interactions with plant physiology, metals, pesticides, and pathogens.
Micro/Nanoplastics in plantation agricultural products: behavior process, phytotoxicity under biotic and abiotic stresses, and controlling strategies
This review examines how microplastics and nanoplastics from sources like plastic mulch and wastewater contaminate agricultural crops, harming plant growth, photosynthesis, and food quality. The findings matter for human health because these plastic particles can accumulate in the fruits and vegetables we eat, carrying toxic chemicals along with them into our diet.
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.
Impact of microplastics on plant physiology: A meta-analysis of dose, particle size, and crop type interactions in agricultural ecosystems
This meta-analysis of 37 studies found that microplastics significantly decrease plant biomass by 13% and chlorophyll content by 28%, while increasing oxidative stress by 20%. Higher doses and smaller particle sizes caused more damage, with particle size having a greater impact than concentration — and root activity was particularly sensitive to microplastic exposure.
Microplastics and particulate matter: assessment of atmospheric pollution in the Region of Hortênsias, Brazil
Researchers measured microplastic concentrations alongside particulate matter in the atmosphere of an urban area, characterizing the size, morphology, and polymer composition of airborne plastic particles and assessing the contribution of different anthropogenic sources to atmospheric MP pollution.
Comparison of microplastic type, size, and composition in atmospheric and foliage samples in an urban scenario
Researchers compared microplastic contamination in outdoor air deposits and on plant leaf surfaces in an urban area and found that both sampling methods detected similar types and sizes of microplastic particles. Fibers were the most common shape found, and polyester and polyethylene were among the most frequently identified polymers. The study suggests that plant foliage could serve as a practical biomonitor for tracking airborne microplastic pollution in cities.
Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches.
This comprehensive review examined how micro-and-nano plastics (MNPs) in terrestrial soils damage plant health by inhibiting water and nutrient uptake, reducing seed germination, impairing photosynthesis, and inducing oxidative stress. The review identified key knowledge gaps in understanding MNP phytotoxicity mechanisms and their implications for food security.
Unraveling the toxic mechanisms of microplastics in aquatic ecosystem: A case study on Vallisneria natans and Myriophyllum verticillatum
Researchers exposed two submerged aquatic plant species (Vallisneria natans and Myriophyllum verticillatum) to PVC, polystyrene, and polyethylene microplastics at three concentrations, finding that all three types significantly inhibited photosynthesis and growth and triggered oxidative stress, with effects varying by plastic type and plant species.
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.
Desenvolvimento De Pitaya Submetida a Estresse Abiótico Em Regiões Semiáridas
Not relevant to microplastics research; the title refers to a study on pitaya (dragon fruit) growth under abiotic stress in semiarid regions (in Portuguese), though the abstract has been incorrectly populated with a microplastics health review — this is a data error in the record.
Mitigating airborne microplastics pollution from perspectives of precipitation and underlying surface types
Researchers collected airborne microplastics under and away from a Ficus tree in Chengdu, China, finding that tree canopy cover and meteorological conditions such as precipitation significantly reduce airborne microplastic concentrations, suggesting vegetation as a natural mitigation measure.
Natural filters of marine microplastic pollution: implications for plants and submerged environments
Researchers reviewed how vegetated ecosystems — like wetlands and marshes — act as natural filters that trap microplastics before they flow into waterways, but found that these trapped particles can still harm soil health and plant growth by causing oxidative stress. The review highlights a critical gap: plants help protect aquatic environments from microplastic pollution while simultaneously being harmed by it themselves.
Adsorption, uptake and toxicity of micro- and nanoplastics: Effects on terrestrial plants and aquatic macrophytes
This review summarizes research on how micro- and nanoplastics interact with terrestrial plants and aquatic macrophytes, finding that many species can absorb or take up plastic particles. Both short-term and long-term plastic exposure triggered stress responses in plants, and since plants are at the base of food chains and a major part of the human diet, there is concern about plastics moving up through the food web. The findings suggest that plastic pollution could potentially affect plant productivity and broader ecosystem function.
Effects of Microplastics on Growth Pattern of Pinus massoniana and Schima uperba
Researchers exposed two economically important tree species (Pinus massoniana and Schima superba) to microplastics and found species-specific differences in how woody plants respond to plastic contamination, with effects on growth, photosynthesis, and oxidative stress.
Quantification and characterization of atmospheric microplastics in a coastal urban area of the city of Lima, Peru
This study quantified and characterized atmospheric microplastic deposition in a coastal urban area of Lima, Peru, finding that microplastics in the air are an emerging but understudied pollution problem in the region. The research addressed a gap in South American data on airborne microplastic behavior and distribution.
Microplastic/nanoplastic toxicity in plants: an imminent concern
This review examines the growing body of research on how microplastics and nanoplastics affect terrestrial plants, from root uptake to changes in growth and gene expression. Researchers found that these particles can alter plant physiology and biochemistry at varying degrees depending on particle size and concentration. The study calls for more research on how plastic contamination in soil may ultimately affect food crop quality and human health through the food chain.
Micro- and nanoplastics-induced stress in plants: uptake, physiological disruption, and toxicity mechanisms
This review paper summarizes existing research on how tiny plastic particles (called microplastics and nanoplastics) are absorbed by plants and damage their health. These plastic particles can build up in plant tissues and disrupt how plants grow and function, which matters because we eat these plants. Since plastic pollution keeps breaking down into smaller pieces that plants absorb, this could eventually affect the safety and quality of our food supply.
Assessing the Influences of Leaf Functional Traits on Plant Performances Under Dust Deposition and Microplastic Retention
This study assessed airborne microplastic accumulation on the leaves of ten urban plant species in an Indian city, finding fragments and films were most abundant, and that leaf functional traits (surface texture, wax content) significantly influenced both microplastic retention and the plants' biochemical stress responses.
