Evaluating the Effectiveness of Vitamins E and C in Mitigating the Toxic Effects of Zinc Oxide Bulk and Nanoparticles on Fish: A Review
Summary
This paper is not relevant to microplastics — it is a review of how vitamins E and C can reduce the toxic effects of zinc oxide nanoparticles on fish in aquatic environments.
Nanotechnology has noticeably developed with diverse applications in every science, especially using nanomaterial. The development of nanotechnology also hurts the environment as many nanoparticles are discharged into the aquatic environment and cause a serious effect on living organisms. Aquatic animals, particularly fish could serve as biological indicators for ecosystem health. The present study investigated the effect of vitamin (E + C) addition on fish exposed to nanoparticles. The previous studies on the impact of zinc oxide (bulk and nanoparticles) of fish in aquatic ecosystems showed that there were clear differences between the accumulation of zinc oxide bulk particles (ZnOBPs) compared to nanoparticles (ZnONPs). Fish exposed to ZnONPs showed a higher accumulation potency in tissues than in ZnOBPs. Also, the activities of antioxidant defense enzymes, biochemical parameters and proximate chemical composition were affected by exposure to nanoparticles. On the other hand, dietary supplementation with vitamins (E and C) resulted in protective effects against these toxic effects in fish.

Ecological 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.
