Joint toxic effects of polystyrene nanoparticles and organochlorine pesticides (chlordane and hexachlorocyclohexane) on Caenorhabditis elegans
AI summary Read the abstract
Joint exposure to polystyrene nanoplastics and organochlorine pesticides (chlordane and HCH) in the roundworm C. elegans caused greater toxicity than either pollutant alone, suggesting synergistic interactions. These findings highlight the importance of studying combined pollutant effects rather than individual chemicals in isolation.
This study revealed polystyrene nanoplastics and organochlorine pesticides (chlordane and hexachlorocyclohexane) caused stronger chronic toxicity including inhibition on growth and lifespan than single exposure, via mechanisms of oxidative damages.

Insights into the effects of aging on the combined toxicity of polystyrene nanoplastics and chlordane against Caenorhabditis elegans
AI summary Read the abstract
Researchers studied how environmental aging of polystyrene nanoplastics changes their combined toxicity with the pesticide chlordane in roundworms. They found that photo-aging altered the physical and chemical properties of the nanoplastics, which in turn modified how the two contaminants interacted and their joint toxic effects. The study highlights that the environmental weathering of plastic particles can significantly change how they interact with other pollutants.
The joint effects of nanoplastics and TBBPA on neurodevelopmental toxicity inCaenorhabditis elegans
AI summary Read the abstract
Researchers used the model organism C. elegans to study the combined neurodevelopmental effects of polystyrene nanoplastics and the flame retardant TBBPA. The study found that combined exposure produced synergistic harmful effects including reduced survival, impaired movement, oxidative stress, and dopaminergic neuron loss, with specific genes related to neurodegenerative pathways playing key roles in the observed toxicity.
Co-Exposure of Nanopolystyrene and Other Environmental Contaminants—Their Toxic Effects on the Survival and Reproduction of Enchytraeus crypticus
AI summary Read the abstract
This study tested the combined toxicity of nanopolystyrene particles alongside pharmaceuticals, metals, and engineered nanomaterials on the soil worm Enchytraeus crypticus, finding that co-exposure often amplified harm to survival and reproduction beyond that of each pollutant alone. The results highlight that real-world mixtures of plastic and chemical contaminants pose greater ecological risks than single-substance assessments suggest.
Combinational effect of titanium dioxide nanoparticles and nanopolystyrene particles at environmentally relevant concentrations on nematode Caenorhabditis elegans
AI summary Read the abstract
Researchers exposed the model nematode Caenorhabditis elegans to environmentally realistic concentrations of both titanium dioxide nanoparticles and nanopolystyrene simultaneously, finding that nanoplastics enhanced the toxicity of the metal oxide particles, worsening locomotion impairment and gut oxidative stress beyond what either pollutant caused alone.
Adsorption behavior and neurotoxic synergy of thallium and polystyrene microplastics in Caenorhabditis elegans
AI summary Read the abstract
Researchers studied how polystyrene microplastics and the toxic metal thallium interact and affect the nervous system of the roundworm C. elegans. They found that the microplastics adsorbed thallium and that the combined exposure produced worse neurotoxic effects than either pollutant alone. The study highlights how microplastics can act as carriers for other environmental toxins, amplifying their harmful effects on living organisms.
