Arbuscular mycorrhizal fungi enhance maize cadmium resistance and reduce translocation: Dependence on microplastics concentration
Researchers investigated how beneficial soil fungi called arbuscular mycorrhizal fungi can help maize plants resist cadmium toxicity in soils contaminated with both microplastics and heavy metals. They found that high concentrations of polyethylene microplastics worsened cadmium toxicity, but inoculation with mycorrhizal fungi significantly improved plant growth, nutrient uptake, and photosynthesis. The study suggests that these fungi could serve as a biological tool for managing crop health in soils with combined microplastic and heavy metal contamination.
Microplastics alter cadmium accumulation in different soil-plant systems: Revealing the crucial roles of soil bacteria and metabolism
A study found that microplastics in soil can change how much cadmium, a toxic heavy metal, is absorbed by food crops, with the effects varying depending on soil type and the amount of plastic present. By altering soil chemistry and bacterial communities, microplastics reshape how pollutants move through farmland and into the food we eat.
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.
Insights on Immobilization of Cd Contamination in Soil: Synergic Impacts of Water Management and Bauxite Residue
Researchers tested whether combining flooding with bauxite residue or lime could reduce the availability of toxic cadmium in contaminated soil. Both combined treatments raised soil pH and increased the proportion of cadmium locked into stable, residual forms while decreasing the easily exchangeable fraction. The bauxite residue treatment proved slightly more effective at immobilizing cadmium, offering a potential soil remediation strategy for heavy metal-contaminated agricultural land.
Impacts of polypropylene microplastics on the distribution of cadmium, enzyme activities, and bacterial community in black soil at the aggregate level
Researchers found that adding polypropylene microplastics to soil contaminated with cadmium (a toxic heavy metal) changed how the metal distributed across different soil particle sizes and shifted bacterial communities. The microplastics increased cadmium availability in some soil fractions, potentially making it easier for plants to absorb this toxic metal. This suggests that microplastic-contaminated farmland may pose greater heavy metal exposure risks for crops and, ultimately, for people who eat them.

Researchers studied how different cadmium concentrations in soil affect the growth, mineral nutrition, and biochemical health of mung bean plants. The study found that increasing cadmium doses significantly disrupted plant mineral homeostasis, reduced chlorophyll and protein content, and impaired antioxidant defense systems in a dose-dependent manner.
Beneficial microbial consortia effectively alleviated plant stress caused by the synergistic toxicity of microplastics and cadmium
Researchers found that combined pollution from microplastics (PVC) and the heavy metal cadmium creates a toxic effect in soil that is worse than either pollutant alone. However, applying beneficial bacteria to contaminated soil helped plants grow better and restored soil nutrients. These findings suggest that probiotic-like bacteria could help repair farmland damaged by microplastic and heavy metal pollution.
