This review highlights zebrafish as an increasingly valuable model organism for studying the toxic effects of micro- and nanoplastics due to their transparent embryos, genetic similarity to humans, and ease of laboratory use. Researchers summarized existing zebrafish studies showing that plastic particles can cross biological barriers and accumulate in tissues, causing various toxic effects. The study positions zebrafish research as a key tool for advancing our understanding of how plastic particle exposure affects living organisms.
Advances of microplastics ingestion on the morphological and behavioral conditions of model zebrafish: A review
This review summarizes research on how microplastic ingestion affects zebrafish, a popular lab animal that shares genetic similarities with humans. Studies show that microplastics cause a range of harmful effects in zebrafish, including abnormal behavior, oxidative stress, immune disruption, and reproductive problems, with smaller particles and higher concentrations causing the most damage. Since zebrafish are used as a model for human health, these findings raise concerns about what similar exposure levels could mean for people.
Genotoxic and Oxidative Damage of Environmental Pollutant Microplastics on Zebrafish (Danio rerio)
Researchers exposed zebrafish to polystyrene and polyethylene microplastics at different concentrations for up to 21 days to measure oxidative stress and DNA damage. The study found that both types of microplastics disrupted the antioxidant system and caused measurable DNA damage, with effects depending on dosage and exposure time. These results suggest that microplastics in waterways could pose genetic and cellular risks to aquatic life.
The Zebrafish as an Alternative Animal Model for Ecotoxicological Research and Testing
This review highlights zebrafish as a valuable model for studying the toxic effects of environmental contaminants, including microplastics, because they share many biological pathways with humans. Zebrafish embryos, larvae, and adults can be used to screen for harmful effects of pollutants quickly and at multiple life stages. The approach helps researchers understand how microplastics and other environmental contaminants might affect human health without requiring direct human testing.
Toxicity evaluation of the combination of emerging pollutants with polyethylene microplastics in zebrafish: Perspective study of genotoxicity, mutagenicity, and redox unbalance
Researchers exposed adult zebrafish to polyethylene microplastics combined with a mixture of common water pollutants for 15 days and assessed DNA damage, mutation rates, and oxidative stress. They found that microplastics alone caused DNA damage and nuclear abnormalities as severe as those caused by the pollutant mixture, challenging the assumption that microplastics are less harmful than chemical contaminants. The study revealed that the fish's antioxidant defenses were overwhelmed across multiple organs, suggesting widespread oxidative damage from microplastic exposure.
Multi-Laboratory Hazard Assessment of Contaminated Microplastic Particles by Means of Enhanced Fish Embryo Test With the Zebrafish (Danio rerio)
A multi-laboratory study using an enhanced zebrafish embryo test assessed the hazard of microplastics contaminated with environmental pollutants, finding that the combination of plastics and sorbed chemicals caused greater toxicity than either alone. The inter-laboratory approach helps validate this testing method for regulatory use in assessing microplastic hazards.
