ClearSynthetical effect of microplastics and chiral drug amphetamine on a primary food source algae Chlorella pyrenoids
Researchers found that polystyrene microplastics increased the toxicity of the illicit drug amphetamine to freshwater algae (Chlorella pyrenoidosa), impairing cell growth and photosynthetic pigment content beyond the effects of the drug alone. Microplastics reduced cell counts through agglomeration and shading effects and also altered the enantioselective fate of the chiral drug.

Researchers found that polystyrene microplastics inhibited the biodegradation of bisphenol A (BPA) by the microalga Chlorella vulgaris, with combined exposure showing greater toxicity than either contaminant alone due to BPA adsorption onto microplastic surfaces.
Size-dependent effect of microplastics on toxicity and fate of diclofenac in two algae
This study investigated how different sizes of polystyrene microplastics affect two species of algae and interact with the common pharmaceutical pollutant diclofenac. Researchers found that the smallest microplastics caused the most significant growth inhibition in algae, and the combined presence of microplastics and diclofenac could alter how each pollutant behaves. The findings underscore how microplastics can change the toxicity and environmental fate of other water contaminants.

Researchers studied how polystyrene microplastics interact with PFBA (a type of forever chemical) when both are present around green algae. Surprisingly, the microplastics actually reduced the toxic effects of PFBA on the algae by binding to the chemical and making it less available, showing that pollutant interactions in the environment can be more complex than expected.
Eco-corona formation lessens the toxic effects of polystyrene nanoplastics towards marine microalgae Chlorella sp.
Researchers studied how eco-corona formation, the adsorption of algal exudates onto nanoplastic surfaces, affects the toxicity of polystyrene nanoplastics to the marine microalga Chlorella sp. The study found that eco-corona formation reduced the toxic effects of nanoplastics, suggesting that natural organic matter in marine environments may partially mitigate nanoplastic toxicity to algae.
Comparison of the effects of continuous and accumulative exposure to nanoplastics on microalga Chlorella pyrenoidosa during chronic toxicity
Researchers compared the effects of continuous versus accumulative exposure to polystyrene nanoplastics on the freshwater microalga Chlorella pyrenoidosa. The study found that accumulative exposure, which better simulates real-world conditions of increasing environmental concentrations, produced different toxicity patterns than continuous exposure, highlighting the importance of exposure design in nanoplastic toxicity research.
Chiral pharmaceutical drug adsorption to natural and synthetic particulates in water and their desorption in simulated gastric fluid
Researchers investigated how microplastics and bioplastics in water adsorb the chiral pharmaceutical drugs fluoxetine and propranolol, finding that while fluoxetine adsorbed to all particle types, no enantioselectivity was observed, and that adsorption was significantly greater in real environmental water matrices than in laboratory buffer solutions.
The combined toxicity effect of nanoplastics and glyphosate on Microcystis aeruginosa growth
Researchers found that cationic nanoplastics adsorb glyphosate so strongly that co-exposure actually reduces the herbicide's toxicity to algae by sequestering it — but the nanoplastics coated in glyphosate adhere more readily to algal surfaces, potentially concentrating both pollutants further up the food chain.
Integrating transcriptomics and biochemical analysis to understand the interactive mechanisms of the coexisting exposure of nanoplastics and erythromycin on Chlorella pyrenoidosa
Researchers used transcriptomics and biochemical analysis to study how nanoplastics and the antibiotic erythromycin interact when both are present in water with the green alga Chlorella pyrenoidosa. They found that the combined toxicity was dynamic, shifting from synergistic to antagonistic effects depending on nanoplastic concentration and exposure duration. The study indicates that co-exposure disrupts algal cell membranes, induces oxidative stress, and reduces photosynthetic efficiency.
Mechanism of transport and toxicity response of Chlorella sorokiniana to polystyrene nanoplastics
Researchers studied how polystyrene nanoplastics are transported into freshwater algae cells and what toxic effects they cause. They found that the tiny plastic particles entered the cells through specific pathways and triggered oxidative stress, inhibiting algae growth. The study provides new insights into how nanoplastics disrupt the base of aquatic food chains by damaging microscopic organisms.
Persistence of algal toxicity induced by polystyrene nanoplastics at environmentally relevant concentrations
Researchers studied whether the harmful effects of polystyrene nanoplastics on marine algae are temporary or long-lasting. They found that while some damage, like oxidative stress, was reversible after exposure ended, other effects such as increased cell membrane damage persisted. The study suggests that even at low, environmentally realistic concentrations, nanoplastics can cause lasting disruption to algal metabolism and cell function.
