Research Progress of Zebrafish Model in Aquatic Ecotoxicology
This review examines how zebrafish are used as model organisms to study the toxic effects of environmental pollutants in water, including microplastics.

The paper provides a reference guide for scientists choosing model animals for aquatic toxicology research.
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.
O Modelo Zebrafish e sua Contribuição ao Meio Ambiente
This Brazilian review examined zebrafish as a model organism for testing water quality and the toxicity of micropollutants including microplastics in wastewater. Zebrafish are increasingly used as a standard test system for evaluating the biological effects of microplastic exposure because their genetics and physiology closely mirror human responses.
Comprehensive review of ecological risks and toxicity mechanisms of microplastics in freshwater: Focus on zebrafish as a model organism
This comprehensive review examines how microplastics affect zebrafish, a widely used laboratory model, covering impacts on the gut, liver, reproductive system, nervous system, and immune function. Researchers found that microplastics can cause oxidative stress, inflammation, and disruption of gut bacteria across multiple organ systems. The review highlights that zebrafish studies provide valuable insights into the biological mechanisms by which microplastics may affect freshwater organisms and, potentially, human health.
Nanoplastics in the Environment and the Effects on the Zebrafish
This study reviewed the effects of nanoplastic exposure on zebrafish, covering how these tiny particles affect development, organ function, behavior, and reproductive success. Zebrafish are a widely used model organism for toxicology, and findings in this species provide insight into potential effects in other vertebrates including humans.
Zebrafish: An emerging model to study microplastic and nanoplastic toxicity
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.
Effects of Microplastics and Nanoplastics on Neurodevelopment and Neurodegeneration in Zebrafish
This review covers how micro- and nanoplastic (MNP) exposure affects neurodevelopment and neurodegeneration in zebrafish, summarising evidence on impaired neurodevelopment, behavioural changes, and markers of neurodegeneration from studies using various polymer types and exposure routes. It frames zebrafish as a key model for understanding MNP neurotoxicity.
Structure activity toxicity of different micro-nanoplastics on developing Zebrafish (Danio rerio) based on individual polymer chemistry

From particle size to brain function: a zebrafish-based review of micro/nanoplastic-induced neurobehavioral toxicity and mechanistic pathways
This review uses zebrafish as a model to examine how micro- and nanoplastics cause neurobehavioral toxicity, linking particle size to brain function disruption.

The findings highlight the growing concern that micro- and nanoplastics are emerging neurotoxicants in aquatic environments.
Size matters: Zebrafish (Danio rerio) as a model to study toxicity of nanoplastics from cells to the whole organism
Researchers used zebrafish as a model organism to study the toxic effects of polystyrene nanoplastics at both cellular and whole-organism levels. They found that smaller nanoplastic particles were taken up more readily by cells and caused greater oxidative stress and developmental abnormalities than larger particles. The study confirms that particle size is a critical determinant of nanoplastic toxicity, with the smallest particles posing the greatest biological risks.
Behavioral Studies of Zebrafish Reveal a New Perspective on the Reproductive Toxicity of Micro- and Nanoplastics
This review summarizes existing research on how micro- and nanoplastics affect the behavior and reproductive health of zebrafish, a common lab model for studying human biology. The findings suggest that tiny plastic particles can disrupt reproductive behavior and act as hormone-like chemicals, and that behavioral changes in fish may serve as early warning signs of reproductive harm that could be relevant to understanding human health risks.
Eco-toxicity assessment of polypropylene microplastics in juvenile zebrafish (Danio rerio)
This study exposed young zebrafish to polypropylene microplastics for 28 days and found that the particles built up in their digestive tracts, causing oxidative stress, liver damage, and blood cell death. The damage increased with higher microplastic concentrations, and brain function was also affected through changes in a key neurotransmitter enzyme. These findings suggest that even common plastics like polypropylene can cause significant organ damage when ingested over time.
