ClearEffects of microplastics and cadmium co-contamination on soil properties, maize (Zea mays L.) growth characteristics, and cadmium accumulation in maize in loessial soil-maize systems
Researchers studied the combined effects of polyethylene microplastics and cadmium on soil properties and maize growth through pot experiments. They found that microplastics altered soil nutrient availability and, depending on size and concentration, either increased or decreased cadmium uptake by the plants. The study suggests that microplastic contamination in agricultural soils can change how crops absorb toxic heavy metals, with potential implications for food safety.
Effects of Co-Contamination of Microplastics and Cd on Plant Growth and Cd Accumulation
Researchers investigated how two types of microplastics, high-density polyethylene and polystyrene, at various concentrations affect cadmium uptake and toxicity in maize plants grown in agricultural soil. The study found that while polyethylene alone had no significant effect, polystyrene at higher doses altered cadmium accumulation patterns, suggesting that different plastic types may interact differently with heavy metals in soil.
Effects of microplastics and cadmium on the soil-wheat system as single and combined contaminants
Researchers found that polyethylene and polypropylene microplastics combined with cadmium reduced wheat chlorophyll concentrations and affected soil-plant systems differently depending on pollution levels, revealing complex interaction effects between co-contaminants.
Ecotoxicological Impacts of Microplastics and Cadmium Pollution on Wheat Seedlings
Researchers investigated the combined effects of polyethylene microplastics and cadmium on wheat seedlings and found that microplastics generally reduced the antioxidant enzyme response that cadmium alone would trigger. The study also found that microplastics altered cadmium bioaccumulation patterns, increasing cadmium uptake in roots at low concentrations but decreasing it at higher levels, suggesting complex interactions between these co-occurring pollutants.
Analyzing the impacts of cadmium alone and in co-existence with polypropylene microplastics on wheat growth
Researchers tested how cadmium and polypropylene microplastics individually and together affect wheat seedling growth, and found that their combined presence intensified negative effects on germination and early development. Cadmium alone inhibited root and shoot growth, and microplastics amplified this damage while also altering antioxidant enzyme activity in the plants. The study suggests that the co-occurrence of heavy metals and microplastics in agricultural soil may create compounding stress on crop health.
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.
Influence of soil microplastic contamination and cadmium toxicity on the growth, physiology, and root growth traits of Triticum aestivum L.
Researchers grew wheat plants in soil contaminated with polyethylene microplastics, the toxic heavy metal cadmium, or both, finding that combined exposure caused the worst damage — shrinking root area, reducing gas exchange in leaves, and lowering key growth indicators. These findings raise concerns about crop yields in farmland where plastic pollution and heavy metal contamination overlap, which is increasingly common.
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.
Interactions of microplastics and cadmium on plant growth and arbuscular mycorrhizal fungal communities in an agricultural soil
Researchers studied how polyethylene and polylactic acid microplastics interact with cadmium contamination to affect maize growth and beneficial soil fungi in agricultural soil. While polyethylene showed minimal direct plant toxicity, high doses of polylactic acid significantly reduced maize biomass, and both plastic types altered the communities of root-associated fungi. The study suggests that co-contamination of microplastics and heavy metals in farmland can jointly disrupt plant health and soil ecosystems.
Coupled Effects of Polyethylene Microplastics and Cadmium on Soil–Plant Systems: Impact on Soil Properties and Cadmium Uptake in Lettuce
Researchers studied how polyethylene microplastics interact with cadmium contamination in soil and its effects on lettuce growth. The study found that microplastics combined with cadmium significantly decreased soil quality and that microplastics can alter cadmium uptake in plants, suggesting that co-contamination of agricultural soils with both pollutants may pose compounded risks to food crop safety.
Research Progress on the Effects of Combined Microplastics and Cadmium Pollution on Plants
This review systematically summarizes research on the combined toxic effects of microplastics and cadmium on plants, including impacts on biomass, oxidative stress, and photosynthesis. The study notes that while preliminary findings suggest combined exposure can exacerbate plant damage, results across studies remain conflicting, and the underlying mechanisms of this combined toxicity need further investigation.
Microplastics promoted cadmium accumulation in maize plants by improving active cadmium and amino acid synthesis
Researchers examined how polystyrene and polypropylene microplastics interact with cadmium contamination to affect soil chemistry and cadmium uptake in maize plants across two soil types. The study found that microplastics generally promoted cadmium accumulation in maize by reducing soil pH and increasing cadmium bioavailability, with effects varying by particle size depending on the soil type.
Effects of combined microplastic and cadmium pollution on sorghum growth, Cd accumulation, and rhizosphere microbial functions
Researchers examined how different types and sizes of microplastics interact with cadmium, a toxic heavy metal, to affect sorghum growth and soil microbes. They found that the combined pollution generally increased plant stress and cadmium uptake, with effects varying by plastic type, particle size, and concentration. The study also revealed that the pollution mixture significantly altered soil bacterial communities and key metabolic pathways involved in nutrient cycling.
Microplastics in Soil Increase Cadmium Toxicity: Implications for Plant Growth and Nutrient Imbalance
A pot experiment showed that adding polyethylene microplastics to soil contaminated with cadmium made the toxic metal more available to plants, increasing cadmium uptake in both roots and shoots. The combined exposure reduced crop yields by up to 38% and disrupted the plant's ability to absorb essential nutrients like nitrogen and phosphorus. This research is important for food safety because it shows microplastics in farm soil can make heavy metal contamination worse, potentially increasing toxic metal levels in crops people eat.
Exploration of Single and Co-Toxic Effects of Polypropylene Micro-Plastics and Cadmium on Rice (Oryza sativa L.)
Researchers investigated the single and combined toxic effects of polypropylene microplastics and cadmium on rice plants, finding that co-exposure altered cadmium bioavailability and produced compounded negative effects on plant growth and development.
Combined Phytotoxicity of Microplastics andLead on the Growth and Physio-BiochemicalCharacteristics of Tobacco (Nicotiana tabacum)
Researchers grew tobacco plants in soil contaminated with both polyethylene microplastics and lead, finding that the combination caused greater damage to photosynthesis and plant growth than either pollutant alone, while microplastics partially reduced how much lead roots absorbed. The study shows that microplastic and heavy metal co-contamination — increasingly common in agricultural soils — poses compounding risks to crop health.
Coupled effects of microplastics and heavy metals on plants: Uptake, bioaccumulation, and environmental health perspectives
This review examines how microplastics and heavy metals work together to harm plants when both are present in soil. Microplastics can absorb heavy metals like lead, cadmium, and arsenic, and when plants take up these contaminated particles, the combined toxic effect is worse than either pollutant alone. This is concerning for human health because crops grown in contaminated soil could carry both microplastics and concentrated heavy metals into the food supply.
Effects of polyurethane microplastics combined with cadmium on maize growth and cadmium accumulation under different long-term fertilisation histories
Researchers examined how polyurethane microplastics combined with cadmium affect maize growth in soils with different long-term fertilization histories. They found that the combination of microplastics and cadmium had varying effects depending on the type of fertilizer previously used, with organic-inorganic fertilized soils showing the most pronounced changes in plant growth and cadmium uptake. The study highlights that a soil's fertilization history plays an important role in how crops respond to microplastic and heavy metal co-contamination.
Polystyrene nanoplastics distinctly impact cadmium uptake and toxicity in Arabidopsis thaliana
In a study using the model plant Arabidopsis, polystyrene nanoplastics increased the uptake and accumulation of the toxic heavy metal cadmium in plant roots. The combined stress of nanoplastics and cadmium caused worse oxidative damage and growth problems than either pollutant alone. This is concerning because it means microplastics in agricultural soil could help toxic metals get into crops more easily, potentially increasing human exposure through food.
Joint toxicity of cadmium (II) and microplastic leachates on wheat seed germination and seedling growth
Researchers investigated how cadmium and chemical compounds that leach from microplastics jointly affect wheat seed germination and seedling growth. They found that microplastic leachates from PVC and polyethylene can interact with cadmium in complex ways, sometimes worsening and sometimes lessening the toxic effects on young wheat plants. The study suggests that the combined presence of heavy metals and microplastics in agricultural soils could pose risks to crop development.
