ClearEcological Risks of Zinc Oxide Nanoparticles for Early Life Stages of Obscure Puffer (Takifugu obscurus)
This study tested the toxic effects of zinc oxide nanoparticles on the early life stages of the obscure puffer fish, finding reduced hatching rates, deformities in larvae, and significant mortality at higher concentrations. While focused on zinc oxide rather than microplastics, the research is relevant because zinc oxide nanoparticles from sunscreen are commonly found alongside microplastics in aquatic environments. The combined presence of multiple nanoparticle pollutants may compound the risks to aquatic ecosystems and the fish people eat.
Micro-polyethylene particles reduce the toxicity of nano zinc oxide in marine microalgae by adsorption
Researchers discovered that polyethylene microplastic particles reduced the toxicity of zinc oxide nanoparticles to marine microalgae by adsorbing the nanoparticles onto their surface, revealing that microplastics can modify the bioavailability of co-occurring contaminants.
Particles rather than released Zn2+ from ZnO nanoparticles aggravate microplastics toxicity in early stages of exposed zebrafish and their unexposed offspring
Researchers investigated the combined effects of polystyrene microplastics and zinc oxide nanoparticles on zebrafish embryos and their unexposed offspring. They found that ZnO particles adhered to microplastic surfaces and amplified toxic effects including growth inhibition, oxidative stress, and hormonal disruption, with impacts carrying over to the next generation. Interestingly, dissolved zinc ions actually reversed some microplastic toxicity, suggesting that it is the physical particles rather than the released zinc that drive the increased harm.
Advances in Understanding Micro‐ and Nanoplastic Toxicity on Farmed Fish and Emerging Nutritional Interventions
This review examined the toxic effects of micro- and nanoplastics on farmed fish and explored emerging nutritional interventions to mitigate those effects. Researchers found that microplastics reduce feed utilization, cause physical abrasion, and trigger oxidative stress in fish, while certain dietary supplements show promise in enhancing fish resilience against microplastic-related toxicity.
Vitamin E Mitigates Polystyrene-Nanoplastic-Induced Visual Dysfunction in Zebrafish Larvae
Researchers found that vitamin E, a common antioxidant, can protect against vision damage caused by polystyrene nanoplastics in zebrafish larvae. The nanoplastics caused eye defects and visual impairment by triggering harmful oxidative stress, but vitamin E treatment significantly reduced this damage, suggesting antioxidants might help counteract some harmful effects of nanoplastic exposure.
Evaluation of distribution, chemical speciation, and toxic effects of CuO and ZnO nanoparticles in Daphnia magna and Danio rerio

This study investigated the effects of zinc nano- and microparticles as dietary supplements on fatty acid metabolism in rats with breast cancer. This pharmacology study focuses on zinc supplementation and cancer biochemistry, with no direct relevance to environmental microplastics.
Captivating Colors, Crucial Roles: Astaxanthin’s Antioxidant Impact on Fish Oxidative Stress and Reproductive Performance
This review examines how the antioxidant astaxanthin can protect fish from oxidative stress and improve their reproductive health in aquaculture settings. While not directly about microplastics, the research is relevant because microplastic exposure causes oxidative stress in fish, and antioxidants like astaxanthin could help mitigate that damage. Understanding these protective mechanisms may be important for maintaining the health and safety of farmed fish destined for human consumption.
Toxic Effects and Mechanisms of Silver and Zinc Oxide Nanoparticles on Zebrafish Embryos in Aquatic Ecosystems
Researchers tested the toxic effects of silver and zinc oxide nanoparticles on zebrafish embryos in natural water environments. They found that both nanoparticle types caused acute toxicity, increased oxidative stress, apoptosis, and autophagy, though toxicity was lower in natural water compared to pure water due to environmental interactions. The study suggests that the complex components in natural water may transform nanoparticles in ways that reduce but do not eliminate their harmful effects on aquatic organisms.
Natural-based solutions to mitigate dietary microplastics side effects in fish
Zebrafish reared for 6 months on diets containing microencapsulated astaxanthin and microplastics showed reduced oxidative stress and lower MP accumulation in liver compared to controls, suggesting antioxidant supplementation can mitigate the toxicological effects of dietary microplastic exposure.

The contribution of additives to microplastic aquatic toxicity - A testing approach with model additives on selected aquatic organisms
Researchers developed a systematic methodology to separate the physical effects of microplastic particles from the chemical effects of their embedded additives on aquatic organisms. The study found that polyethylene microplastics alone showed no significant toxicity to water fleas or protozoa, while the additive zinc oxide was toxic independently. Artificial aging changed how much additive was released from the plastics but did not change the overall toxicity to the tested organisms.

This review examines how microplastics and nanoplastics cause oxidative stress, a harmful chemical imbalance, in aquatic organisms from plankton to fish. These tiny plastics accumulate in the food chain and may reach humans through seafood consumption. While the evidence of harm in aquatic species is growing, more research is needed to fully understand the implications for human health.
The contribution of additives to microplastic aquatic toxicity – A testing approach with model additives on selected aquatic organisms
Researchers developed a systematic testing approach to distinguish between the physical effects of microplastic particles and the chemical effects of their additives on aquatic organisms. The study found that polyethylene microplastics alone showed no significant toxicity to water fleas or protozoa, but the inorganic additive zinc oxide was toxic on its own. The findings suggest that the additives embedded in plastics, rather than the plastic particles themselves, may be the primary drivers of toxicity in some cases.
