Altered biotoxicity of cadmium to freshwater green algae by different concentrations of polystyrene
AI summary Read the abstract
Polystyrene microplastics at low concentrations partially reduced cadmium toxicity to freshwater green algae, while higher concentrations exacerbated it, demonstrating that combined pollution effects on algae are concentration-dependent.
Microplastic pollution has become a global problem, threatening water bodies and aquatic organisms around the world. Heavy metal pollution in the aquatic environment is an environmental issue of long-term concern, and relatively few studies have been conducted on the compound toxic pollution of freshwater algae by microplastics and heavy metals. Therefore, in this study, Cd and polystyrene (PS) were selected as representative heavy metals and microplastics in the environment, and the toxic effects of the two pollutants on freshwater algae were investigated by determining the biomass of algal growth, chlorophyll a content, and the bioconcentration of heavy metals. It was found that the two pollutants alone could inhibit the growth and photosynthesis of the algae, and the toxicity increased with the increase of concentration. When the two pollutants were combined, the toxicity of Cd depended on the concentration of PS, and both low (1 mg/L) and high (100 mg/L) concentrations of PS increased the toxicity of Cd in a synergistic manner, whereas the medium concentration (10 mg/L) of PS showed an antagonistic effect, which was able to inhibit the toxicity of Cd.

Comparison of the combined toxicity of polystyrene microplastics and different concentrations of cadmium in zebrafish
AI summary Read the abstract
Researchers studied the combined toxic effects of polystyrene microplastics and cadmium at different concentrations in zebrafish over a 10-day exposure period. The study found that microplastics could either amplify or reduce cadmium toxicity depending on the metal concentration, affecting survival, growth, and antioxidant responses in complex ways.
Interactive Effects of Polyethylene Microplastics and Cadmium on Growth of Microcystis aeruginosa
AI summary Read the abstract
Researchers examined what happens when polyethylene microplastics and the heavy metal cadmium are both present in freshwater, focusing on their effects on a bloom-forming algae species. Evidence indicates that the combination caused greater stress on the algae than either pollutant alone, though microplastics partially reduced cadmium toxicity by adsorbing some of the metal.

AI summary Read the abstract
Researchers studied freshwater algae exposed to both cadmium and polystyrene nanoplastics in the lab. Combined exposure caused more growth problems, oxidative damage and cell structure disruption than cadmium alone, even though cells did not accumulate more cadmium, with gene and metabolite changes pointing to disrupted metal handling, membranes and nutrient processing.
Toxicity effects of microplastics and nanoplastics with cadmium on the alga Microcystis aeruginosa
AI summary Read the abstract
Researchers examined the combined toxicity of microplastics, nanoplastics, and cadmium on the freshwater alga Microcystis aeruginosa. The study found that while cadmium alone was most toxic, the combination of plastics and cadmium produced synergistic harmful effects, with nanoplastics causing greater cadmium release and more severe disruption to algal cell membranes than microplastics.
Toxicity Effects of Microplastics and Nanoplastics with Cadmium on the Alga Microcystis Aeruginosa
AI summary Read the abstract
This study tested how microplastics and nanoplastics interact with the heavy metal cadmium to affect the growth of a common freshwater algae, finding that combined exposure was more harmful than either contaminant alone. Nanoplastics adsorbed more cadmium per particle but their smaller size enabled them to penetrate algal cells more easily, with complex effects on cellular toxicity.
