Impact of Chlorella vulgaris Bioremediation and Selenium on Genotoxicity, Nephrotoxicity and Oxidative/Antioxidant Imbalance Induced by Polystyrene Nanoplastics in African Catfish (Clarias gariepinus)
AI summary Read the abstract
Researchers exposed African catfish to polystyrene nanoplastics and found the particles caused DNA damage, kidney tissue changes, and oxidative stress. Supplementing the fish diet with the algae Chlorella vulgaris or the mineral selenium significantly reduced these harmful effects. The study suggests that certain natural supplements may help protect aquatic organisms from nanoplastic-related damage.
Contamination of the environment with nano- and microplastic particles exerts a threatening impact on the aquatic ecosystems and sustainable catfish aquaculture. The presence of nanoplastics has been found to have a detrimental impact on both aquatic and terrestrial ecosystems. The present study examines the effect of polystyrene nanoplastics (PS NPs) on the DNA, erythrocytes, oxidative status and renal histology of catfish, in addition to the potential protective effects of Chlorella vulgaris bioremediation and selenium to hinder this effect. Six equal groups of fish were used as follows: Group 1 served as a control group and received water free from PS NPs; Group 2 was exposed to PS NPs at a concentration of 5 mg/L; Group 3 was exposed to PS NPs (5 mg/L) + selenium (1 mg/kg diet); Group 4 was exposed to PS NPs (5 mg/L) + C. vulgaris (25 g/kg diet); Group 5 was supplemented with C. vulgaris (25 g/kg diet); and Group 6 was supplemented with selenium (1 mg/kg diet). The exposure period was 30 days. The results indicated that PS NPs induced oxidative stress by significantly elevating malondialdehyde activities and slightly reducing antioxidant biomarkers, resulting in DNA damage, increased frequency of micronuclei, erythrocyte alterations, and numerous histopathological alterations in kidney tissue. Selenium and C. vulgaris significantly ameliorated the oxidative/antioxidant status, reducing DNA damage, micronucleus frequency, erythrocyte alterations, and improving the morphology of kidney tissue. Nevertheless, further research is needed for a profound understanding of the mechanism behind the toxicity of nano-microplatics in aquatic systems.

Protective efficacy of dietary natural antioxidants on microplastic particles-induced histopathological lesions in African catfish (Clarias gariepinus)
AI summary Read the abstract
Researchers tested whether dietary natural antioxidants could protect African catfish from tissue damage caused by microplastic ingestion. Fish fed microplastics alone showed significant kidney, liver, and intestinal damage including cellular necrosis and tissue fibrosis, while fish receiving lycopene, citric acid, or chlorella alongside the microplastics showed substantially reduced tissue injury. The study suggests that natural antioxidant supplementation may help mitigate the harmful effects of microplastic exposure in aquaculture species.

AI summary Read the abstract
Researchers tested whether nano-selenium supplements could protect grass carp from damage caused by polystyrene microplastics. They found that nano-selenium reduced the tissue damage, oxidative stress, and immune suppression caused by microplastic exposure, and helped restore healthy gut bacteria. The study suggests that dietary nano-selenium may be a practical strategy for protecting farmed fish from the harmful effects of microplastic pollution in aquatic environments.
