Environmental pollutants cause health problems as well as affect living or non-living things in terrestrial and aquatic ecosystems. Many harmful substances, the use of which is increasing today, directly or indirectly cause deterioration in the quality of life of living things. Pollutions originating from water-primarily affect fish health. Negative effects are observed on the physiological, biochemical, and anatomical structures of fish feeding, migrating, and breeding in the aquatic environment due to pollutants. Zebrafish is an important model organism thanks to its development and easy reproduction. Many potential pollutants in the aquatic environment degrade the quality of water. Natural, industrial, domestic, etc. To the aquatic environment. Pollutants of organic or inorganic origin emitted from sources can cause toxic effects on fish. Pesticides, which are considered as one of these pollutants, are used to destroy the effects of harmful pests while causing death in living things, their negative effects on the reproductive system like many systems have been revealed. Heavy metals negatively affect the biological systems of fish by causing bioaccumulation by ingestion of fish mostly through respiration. Although endocrine-disrupting chemicals (EBC) affect different tissues and organs for generations, their effects on the reproductive system increase by affecting the hormonal system. Nanoparticles affect different biological systems as well as the reproductive system. In this article, the histological effects of environmental pollutants on zebrafish ( Danio reiro) reproductive organs and the reasons for choosing zebrafish as a model organism re-evaluated.
