ClearMicrobial 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.
Aquatic Plants in phytoremediation of contaminated water: Recent knowledge and future prospects
This paper is not about microplastics; it reviews phytoremediation — the use of aquatic plants to remove heavy metals from contaminated water — covering sources of heavy metal pollution, remediation techniques, and factors affecting plant uptake efficiency.
Research on the Mechanisms of Plant Enrichment and Detoxification of Cadmium
This review examines how plants absorb, transport, and accumulate the heavy metal cadmium from contaminated soil, as well as the detoxification mechanisms plants use to cope with cadmium stress. While focused on cadmium rather than microplastics, the research is relevant because microplastics in soil can alter cadmium mobility and uptake by crops, potentially affecting food safety.
Effects of micro and nanoplastics on plant-assisted bioremediation for contaminated soil recovery: A review
This review examines how the growing presence of micro- and nanoplastics in contaminated soils affects plant-assisted bioremediation, finding that microplastics disrupt the plant-microbe rhizosphere interactions that make phytoremediation effective for removing heavy metals and degrading organic pollutants.
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.
Influencing mechanisms of microplastics existence on soil heavy metals accumulated by plants
This review summarizes existing research on how microplastics in soil affect the uptake of heavy metals by plants. Microplastics can change soil chemistry and microbial communities in ways that alter how much toxic metals plants absorb through their roots. This is concerning for human health because microplastic-contaminated agricultural soil could lead to crops that contain higher levels of dangerous heavy metals.
Phytoremediation of Co-Contaminated Environments: A Review of Microplastic and Heavy Metal/Organic Pollutant Interactions and Plant-Based Removal Approaches
This review examined how microplastics interact with heavy metals and organic pollutants in soil and how plants can be used to clean up these mixed contamination scenarios. Researchers found that microplastics can either increase or decrease the toxicity of co-pollutants depending on their chemical properties, and emerging approaches like genetically modified plants and microbial partnerships show promise for improving cleanup efforts.
Effects of microplastics on the phytoremediation of Cd, Pb, and Zn contaminated soils by Solanum photeinocarpum and Lantana camara
Researchers found that polyethylene microplastics at different concentrations affected the phytoremediation efficiency of cadmium, lead, and zinc from contaminated soils by Solanum photeinocarpum and Lantana camara, with effects varying by microplastic dose and plant species.
Microplastics may increase the environmental risks of Cd via promoting Cd uptake by plants: A meta-analysis
This meta-analysis found that microplastics in soil can increase how much cadmium (a toxic heavy metal) plants absorb. This is concerning because it means microplastic pollution could make our food crops more contaminated with heavy metals, adding another health risk on top of the plastics themselves.
Synergistic Effects of Earthworms and Plants on Chromium Removal from Acidic and Alkaline Soils: Biological Responses and Implications
Not relevant to microplastics — this study examines how earthworms and plants work together to remove chromium from contaminated soils, testing bioremediation effectiveness across different soil acidities and pollution levels.
Effects of polyethylene microplastics on cadmium accumulation in Solanum nigrum L.: A study involving microbial communities and metabolomics profiles
This study found that polyethylene microplastics in soil reduced the ability of a plant known for cleaning up cadmium contamination to absorb the toxic metal. The microplastics changed the soil's microbial community and altered the plant's metabolism in ways that disrupted its natural heavy metal uptake process. This is important because it suggests microplastic pollution in farmland could interfere with natural and engineered soil cleanup strategies for heavy metals.
The Effect of Microplastics-Plants on the Bioavailability of Copper and Zinc in the Soil of a Sewage Irrigation Area
Researchers examined how different concentrations of microplastics affect the bioavailability of copper and zinc in sewage-irrigated soils, finding that microplastics can alter heavy metal mobility and plant uptake, with implications for food safety in contaminated agricultural areas.
Decontamination of pollutants present in water, air, and soil through phytoremediation: a critical review
This critical review examines phytoremediation — the use of plants to remove contaminants from soil, water, and air — covering mechanisms such as phytoextraction, phytodegradation, and rhizofiltration, and assessing their effectiveness for heavy metals, organic pollutants, and microplastics.
Enhancing the Phytoextraction of Cd, Cu, Pb, and Zn by Portulaca oleracea in a Heavily Contaminated Soil Using Low Molecular Weight Organic Substances: Is Phytoremediation Viable?
This paper is not about microplastics. It tested whether adding chelating agents like EDTA to heavily contaminated soil could help purslane plants extract more lead, cadmium, copper, and zinc from the ground. While the researchers found that EDTA significantly increased metal uptake by plants, they concluded that phytoremediation is not practical for extremely contaminated soils due to the time required.
Bioremediation of Toxic Pollutants
This paper is not relevant to microplastics research — it is a broad review of bioremediation approaches for environmental pollutants including heavy metals and textile dyes, with no specific focus on microplastics.
Micro- and nano-plastics pollution and its potential remediation pathway by phytoremediation.
This review proposed phytoremediation as a viable approach for removing micro- and nano-plastics from contaminated environments, reviewing evidence that plants can take up particles through roots and translocate them to shoots, and discussing the potential for hyperaccumulating species to be used in soil and water decontamination.
Combined effects of microplastics and cadmium on the soil-plant system: Phytotoxicity, Cd accumulation and microbial activity
Researchers tested how different microplastic types combined with cadmium affect plant growth and soil health. Aged and biodegradable microplastics increased cadmium uptake in mustard greens more than fresh conventional plastics did. The study also found that microplastics altered soil microbial activity, suggesting that plastic pollution in farmland could change how plants absorb toxic metals from contaminated soil.
Microplastics in Mediterranean Agricultural Soils: Effects on Soil Properties, Metal Accumulation in Plants, and Implications for Sustainable Agroecosystems
Scientists found that tiny plastic particles in soil make it easier for toxic metals like lead and zinc to move into plants we might eat. Even small amounts of microplastics changed how metals behave in the soil, with some types of plastic causing up to 20% more metal absorption in plants. This matters because these contaminated plants could end up in our food supply, potentially increasing our exposure to harmful metals.
POTENTIAL EFFECTS OF ENVIRONMENTAL MICROPLASTICS ON PHYTOREMEDIATION OF Cu, Mn and Sr FROM SERBIAN URBAN SOILS
Researchers investigated the prevalence of microplastics in soils from four Serbian cities and evaluated how microplastic contamination affects the uptake of copper, manganese, and strontium by the bioindicator plant Capsella bursa-pastoris, assessing implications for phytoremediation of urban contaminated soils.
The trend of bioremediation as an effective technology in soil decontamination
Not relevant to microplastics — this review covers bioremediation techniques using bacteria, fungi, and plants to clean up soil contaminated with hydrocarbons, pesticides, and heavy metals.
