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.

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.

Effects of microplastics on cadmium accumulation by rice and arbuscular mycorrhizal fungal communities in cadmium-contaminated soil

Researchers studied how three types of microplastics interact with cadmium contamination in rice paddies, examining effects on plant growth, metal uptake, and soil fungal communities. They found that while microplastics generally increased cadmium availability in soil, they actually decreased cadmium accumulation in rice tissues. Notably, biodegradable polylactic acid microplastics caused more harm to plant growth and soil communities than conventional plastic types, challenging the assumption that biodegradable plastics are always safer.

Plant Cadmium Toxicity and Biomarkers Are Differentially Modulated by Degradable and Nondegradable Microplastics in Soil

Researchers compared how degradable (polylactic acid) and nondegradable (polypropylene) microplastics affect cadmium toxicity in plants grown in contaminated soil. They found that polypropylene caused greater root growth inhibition, while polylactic acid led to higher levels of cellular stress markers at certain concentrations. The study reveals that both types of microplastics can alter soil chemistry and increase the uptake of heavy metals by crops, but through different mechanisms.
