ClearPOTENTIAL EFFECTS OF ENVIRONMENTAL MICROPLASTICS ON PHYTOREMEDIATION OF Cu, Mn and Sr FROM SERBIAN URBAN SOILS

Distribution of microplastics in (sub)urban soils of Serbia and Cd, As, and Pb uptake by Capsella bursa-pastoris (L.) Medik
Researchers surveyed urban and suburban soils in Serbia and found widespread microplastic contamination that influenced how plants absorb heavy metals like cadmium, arsenic, and lead. The presence of microplastics in soil altered the availability of these toxic metals to the medicinal plant shepherd's purse. The study highlights that microplastics can change how other pollutants move through the soil-plant system, potentially affecting both ecosystem and human health.

Meta-analysis of impacts of microplastics on plant heavy metal(loid) accumulation
A meta-analysis of 3,226 observations found that microplastics promoted plant uptake of cadmium (11%), lead (30%), and copper (47.1%) in shoots, but decreased arsenic accumulation by 22.6%. Microplastics increased available soil concentrations of these metal cations while lowering soil pH, with machine learning revealing that soil pH and total heavy metal concentration are the primary drivers of plant metal accumulation.
Impact of microplastics on bioaccumulation of heavy metals in rape (Brassica napus L.)
Researchers found that microplastics influenced the bioaccumulation of copper and lead in rapeseed plants, with effects varying by microplastic concentration and heavy metal type, revealing how plastic pollution may alter contaminant uptake in crops.
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.
Influence of Different Microplastic Forms on pH and Mobility of Cu2+ and Pb2+ in Soil
Researchers investigated how different microplastic forms influence soil pH and the mobility of copper and lead ions, finding that microplastics' surface properties and electrostatic interactions can modify heavy metal sorption and alter the soil microenvironment.
Microplastic-Mediated Heavy Metal Uptake in Lettuce (Lactuca sativa L.): Implications for Food Safety and Agricultural Sustainability
Researchers grew lettuce in contaminated soil mixed with different types of microplastics, including fibers, glitter, and fragments from bags and bottles. They found that microplastics altered how heavy metals like lead, cadmium, and copper moved through the soil and into the plants, sometimes increasing uptake of toxic metals in roots while decreasing others in leaves. The results raise concerns about food safety in agricultural areas where both microplastic and heavy metal contamination overlap.
ИСТОЧНИКИ И ПУТИ ТРАНСЛОКАЦИИ МИКРОПЛАСТИКА В ПОЧВЕ И РАСТЕНИЯХ
This review examines sources and translocation pathways of microplastics in soil and plants across agricultural and other terrestrial ecosystems, discussing how microplastics sorb heavy metals and other pollutants and reviewing evidence for their bioaccumulation in agricultural products and implications for human health.
Antidote or Trojan horse for submerged macrophytes: Role of microplastics in copper toxicity in aquatic environments
Researchers investigated whether polyethylene microplastics act as an antidote or a Trojan horse for copper toxicity to submerged aquatic plants. The study found that microplastics reduced dissolved copper concentrations through adsorption but could then release copper-loaded particles that were taken up by plants. The results suggest that microplastics may initially reduce copper toxicity in water but ultimately serve as carriers that deliver copper directly into plant tissues.
Assessment of soil microplastics: An overview on toxicity, effects on heavy metals adsorption, solid-phase extraction, and detection techniques
This review examined how microplastics in soil enter the food chain and pose human health risks, with particular attention to their role as carriers for heavy metals. Agricultural practices like plastic mulching and sewage sludge application were identified as major sources of soil MP contamination.
Impact of Co-Contaminants (Microplastics and Others) on Heavy Metal/Metalloid Toxicity and Accumulation in Plants
This review examines how microplastics act as co-contaminants alongside heavy metals and metalloids in agricultural soils, influencing their toxicity and uptake by plants. Researchers found that the presence of microplastics can alter how metals like cadmium, arsenic, and lead accumulate in plant tissues, with implications for crop safety and agricultural productivity.
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.
Quantification and Ecotoxicological Evolution of Microplastics in Soil Ecosystem
This review discusses methods for quantifying microplastics in soil and aquatic sediments and assesses their ecotoxicological effects on invertebrates, plants, and microbes, finding that MPs impair soil function and food web dynamics across concentration ranges commonly found in contaminated environments.
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.
Coexistence of microplastics and heavy metals in soil: Occurrence, transport, key interactions and effect on plants
This review examines how microplastics and heavy metals like lead, cadmium, and arsenic interact in soil, often creating combined toxic effects on plants that differ from either pollutant alone. These interactions are relevant to human health because contaminated crops can transfer both microplastics and heavy metals to people through the food supply.
