Organophosphate pesticides are widely used worldwide to increase agricultural efficiency. However, it has been found that these chemicals generally do not show target specificity and that the spinal beings outside the target are also affected by the exposure to pesticides. The aim of this study is to explore the potential harmful effects of phonofosin zebra fish (Danio rerio), an organophosphate insecticide, on the respiratory tissues. Early Zebra fish was exposed to 1, 2 and 4 mg/L phonophosis for 96 hours. The bulbs were removed and detected in the Bouin liquid and buried in the paraffin. Cuts of 5 μm thickness painted with hematoxylene eosin, Gomori tricrom or periodic acid Schiff paintings. Examples were studied in the light microscope and the histological changes were compared with 0.1 % dimethylsulfoxide (DMSO) solvent control group examples. Fonofos in the solvents, epithelial climbing in the tissue, twisting in the secondary lamels, decumation, epithelial hyperplasia and lamellar fusion caused. The solvents showed noticeable histopathological differences with exposure to phonophos. Fonophosus is a threat to the non-target organisms living in water ecosystems.
