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.

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.
