Evaluation of the toxicity effects of microplastics and cadmium on earthworms
Researchers evaluated the combined toxicity of microplastics and cadmium on earthworms (Eisenia fetida) using both short-term and long-term exposure experiments. They found that the co-exposure produced interactive toxic effects on antioxidant enzyme activity and caused DNA damage, with toxicity severity influenced by microplastic particle size and concentration. The study suggests that the presence of microplastics in contaminated soils can modify how heavy metals like cadmium affect soil organisms.
Behaviour, ecological impacts of microplastics and cadmium on soil systems: A systematic review
This systematic review examines how microplastics and cadmium interact in soil, finding that they can make each other more harmful. Microplastics can carry toxic cadmium further through soil and increase its uptake by plants, which could mean more heavy metal contamination in the food we eat.

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.
Microplastics aggravate the joint toxicity to earthworm Eisenia fetida with cadmium by altering its availability
Researchers exposed earthworms to polyethylene microplastics combined with cadmium and found that co-exposure caused significantly worse effects than either pollutant alone, including increased avoidance behavior, weight loss, and DNA damage. The microplastics increased the bioavailability of cadmium in soil by up to 1.43-fold and boosted cadmium accumulation in earthworm tissue by up to 2.65-fold. The study demonstrates that microplastics can worsen heavy metal toxicity to soil organisms by making the metals more accessible for uptake.
Coexistence of microplastics and Cd alters soil N transformation by affecting enzyme activity and ammonia oxidizer abundance
Researchers studied how the combined presence of microplastics and cadmium in soil affects nitrogen cycling, a process essential for soil fertility. They found that the pollutant mixture altered enzyme activity and shifted the balance of ammonia-oxidizing microbial communities more than either contaminant alone. The findings suggest that co-contamination of soils with microplastics and heavy metals could disrupt nutrient cycles critical for plant growth.

Researchers assessed the combined effects of polypropylene microplastics and a heavy metal mixture (copper, chromium, and zinc) on the earthworm Eisenia foetida and on soil organic carbon, nitrogen, and phosphorus cycling. The study found that co-contamination exacerbated adverse effects on earthworm survival and soil nutrient dynamics compared to single-pollutant exposures, highlighting synergistic risks of combined microplastic and metal pollution in terrestrial ecosystems.

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.

Researchers investigated how polyethylene microplastics and cadmium interact in soybean-soil systems and found that specific microplastic concentrations enhanced cadmium accumulation in roots under moderate contamination. Higher microplastic levels reduced beneficial soil bacteria like Sphingomonas and Bradyrhizobium and suppressed nitrogen-cycling functions. The study demonstrates that microplastics fundamentally alter heavy metal behavior through interconnected plant-metabolite-microbe interactions in agricultural soils.

Researchers tested how polystyrene microplastics and biosolid application jointly affected cadmium toxicity and bioaccumulation in the soil worm Enchytraeus crypticus, finding that biosolid application altered metal availability in ways that modified the toxicity of cadmium under MP presence. The study highlights the complexity of predicting contaminant risks in agricultural soils with multiple amendment inputs.
Susceptibility of Cd availability in microplastics contaminated paddy soil: Influence of ferric minerals and sulfate reduction
When microplastics and cadmium contaminate paddy soil together — a common situation in agricultural areas — microplastics increase the availability of cadmium to plants, raising the risk of cadmium uptake into food crops like rice. The mechanism involves microplastics releasing dissolved organic matter that disrupts iron mineral cycling and promotes sulfate-reducing bacteria, which in turn mobilize cadmium from soil particles. These findings highlight that microplastic pollution in farmland does not act alone — it can amplify the toxicity of co-occurring heavy metal contaminants.
Presence of microplastics enhanced the toxicity of silver nanoparticles on the collembolan Folsomia candida
Researchers examined the combined effects of polyvinyl chloride microplastics and silver nanoparticles on the soil organism Folsomia candida over 28 days. They found that co-exposure produced synergistic toxic effects, reducing reproduction by over 50% and increasing silver accumulation in the organisms by nearly 88% compared to silver nanoparticle exposure alone. The study suggests that the presence of microplastics in soil can amplify the toxicity of other contaminants by enhancing their bioaccumulation.
