Summary

Researchers assessed the toxic effects of polyethylene terephthalate glitter microplastics on Artemia salina (brine shrimp) as a model zooplankton species. The study found that glitter ingestion caused gut wall damage, decreased cholinesterase activity, and demonstrated biomagnification potential, suggesting that synthetic glitter particles pose measurable toxicological risks to aquatic organisms.

Our research aims to assess the toxic impacts of polyethylene terephthalate (PET) glitters on Artemia salina as a model zooplankton. The mortality rate was assessed using a Kaplan Maier plot as a function of various microplastic dosages. The ingestion of microplastics was confirmed by their presence in digestive tract and faecal matter. Gut wall damage was confirmed by dissolution of basal lamina walls and an increase in the secretory cells. A significant decrease in the activities of cholinesterase (ChE) and glutathione-S-transferase (GST) were noted. A decrease in catalase activity could be correlated to an increase in the generation of reactive oxygen species (ROS). Cysts incubated in presence of microplastics exhibited delay in their hatching into 'umbrella' and 'instar' stages. The data presented in the study would be useful for scientists working on discovering new sources of microplastics, related scientific evidences, image data and model of study.
