ClearAdvantages of the zebrafish (Danio rerio) model in solving contemporary problems of neurotoxicity, teratotoxicity and genotoxicity of xenobiotics
This paper is not about microplastics per se; it is a Polish-language review of the zebrafish (Danio rerio) model in toxicology, covering its use for assessing neurotoxicity, teratotoxicity, and genotoxicity of xenobiotics including nanoparticles and microplastics, with discussion of the micronucleus and comet assays used to detect genetic damage.
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.
Zebrafish embryos as a biological model to study the effects of nanoplastics
This study used zebrafish embryos as a model system to investigate the toxic effects of nanoplastics, finding developmental disruptions at concentrations relevant to environmental exposure. Zebrafish embryos are a widely used model because their transparency allows direct visualization of organ development during toxicant exposure.
Biological toxicity of sulfamethoxazole in aquatic ecosystem on adult zebrafish (Danio rerio)
Not relevant to microplastics — this study examines how the antibiotic sulfamethoxazole affects zebrafish health, finding that chronic exposure causes liver and gill oxidative damage and disrupts gut bacteria, with no focus on plastic pollution.
Polystyrene nanoplastics enhance the toxicological effects of DDE in zebrafish (Danio rerio) larvae
Researchers found that polystyrene nanoplastics enhanced the toxicity of the pesticide metabolite DDE in zebrafish larvae, with co-exposure causing greater developmental abnormalities and oxidative stress than either pollutant alone.
New insight into long-term effects of phthalates microplastics in developing zebrafish: Evidence from genomic alteration and organ development
Researchers investigated the long-term developmental effects of three common plasticizers (DBP, DEP, and DEHP) leaching from microplastics on zebrafish larvae. The study found that phthalate exposure caused higher mortality, morphological abnormalities, and significant changes in genes related to cardiovascular development, tail formation, and other critical developmental pathways.
Developmental Effects of a Non-Dioxin-Like Polychlorinated Biphenyl Mixture on Zebrafish (Danio rerio)
Not relevant to microplastics — this study examines how a mixture of non-dioxin-like polychlorinated biphenyls (PCBs) affects the development, behavior, and heart function of zebrafish, with no microplastic component.
Exploring developmental toxicity of microplastics and nanoplastics (MNPS): Insights from investigations using zebrafish embryos
This review summarizes research on how micro- and nanoplastics harm embryo development using zebrafish as a model organism that shares genetic similarities with humans. Studies show these tiny plastic particles cause damage to the brain, heart, gut, and immune system of developing embryos, largely through oxidative stress and cell death pathways.
Screening for microplastics in drinking water and its toxicity profiling in zebrafish
Researchers tested several brands of bottled water sold in India and found microplastics present in all samples, with polyethylene being the most common polymer detected. When zebrafish embryos were exposed to these microplastics, they showed concentration-dependent toxic effects including developmental abnormalities and organ accumulation. The study raises concerns about human health risks from microplastics in commercially available drinking water.
Structure activity toxicity of different micro-nanoplastics on developing Zebrafish (Danio rerio) based on individual polymer chemistry
This dissertation examined the toxicity of individual polymer chemistries—rather than generic microplastic mixtures—on zebrafish embryos and larvae, finding polymer-specific differences in developmental toxicity, behavioral disruption, and biochemical pathway activation across multiple plastic types.
Embryotoxicity of polystyrene microplastics in zebrafish Danio rerio
Researchers exposed zebrafish embryos to polystyrene microplastics during early development and observed serious physical deformities, particularly in the spine, tail, and eyes, despite no increase in mortality. The exposed larvae also showed elevated expression of genes involved in oxidative stress defense and cellular detoxification. The findings suggest that microplastics can disrupt critical developmental stages in freshwater fish even when they do not directly cause death.
Zebrafish Insights into Nanomaterial Toxicity: A Focused Exploration on Metallic, Metal Oxide, Semiconductor, and Mixed-Metal Nanoparticles
This review summarizes research on how various nanomaterials, including nano-sized plastics, affect zebrafish, which are commonly used as stand-ins for studying human health effects. Exposure to nanomaterials caused developmental defects, organ damage, behavioral changes, and reproductive problems in zebrafish. These findings help scientists understand the potential health risks of nanomaterial exposure to humans and the environment.
In vivo toxicity of Dioctyl Phthalate in adult and zebrafish larvae.
Researchers tested the toxicity of the plasticizer dioctyl phthalate on zebrafish embryos and adults, finding developmental abnormalities and dose-dependent organ damage including fatty liver, renal necrosis, and oligospermia, with larvae more sensitive than adults.
Effects of pristine or contaminated polyethylene microplastics on zebrafish development
Researchers examined the effects of both pristine and pollutant-contaminated polyethylene microplastics on zebrafish development through chronic exposure. The study assessed how microplastics, both alone and as carriers of adsorbed organic pollutants, affect developing fish. The findings provide new insights into how contaminated microplastics may create additional routes for toxic compounds to enter aquatic food webs.
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. Zebrafish are ideal because they reproduce quickly, are inexpensive to maintain, and allow researchers to study effects at the genetic, cellular, and whole-organism level. The paper provides a reference guide for scientists choosing model animals for aquatic toxicology research.
Neurotoxicity of Some Environmental Pollutants to Zebrafish
This review examines how environmental pollutants including microplastics, pesticides, and drug residues can damage the nervous system, using zebrafish as a model organism. The studies show that microplastics can cause neurotoxic effects on their own and also increase the brain-damaging potential of other pollutants they carry, which has implications for understanding how these contaminants might affect the human nervous system.

Initial Assessment the Effects of Polyethylene Microplastics on the Growth of Zebrafish Embryos Danio rerio
Exposure of zebrafish (Danio rerio) embryos to polyethylene microplastics over 96 hours increased mortality rates and caused morphological abnormalities including pericardial edema and yolk sac deformities. The study provided initial toxicological evidence of PE microplastic developmental toxicity in a standard aquatic model organism.
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.
Impacts of real microplastic leachates on the development and behavior of developing zebrafish (Danio rerio)
