Histological investigation of the liver of freshwater fish Cyprinus carpio after intoxication with Ibuprofen

Water contamination has a detrimental impact on streams and rivers, leading to a reduction in the diversity of terrestrial, aquatic, and aerial species. Furthermore, it disrupts the intricate equilibrium of existence. Pharmaceuticals are artificial compounds that belong to several chemical families and exhibit a diverse array of environmental biochemical responses, rendering them the most recent group of pollutants in all aquatic environments. The present study investigated the impact of Ibuprofen on freshwater fish Cyprinus carpio by determining the LC50 value of Ibuprofen during exposure to various concentrations for 24, 48, 72, and 96 hours in sets of aquariums at a concentration of 0.23ml/L. To investigate the impact of Ibuprofen on fish C. carpio, the study evaluates the effects of a sublethal concentration of 1/10th (0.023ml/L) of Ibuprofen LC50 on fish liver histology over a period of 7, 14, 21, and 28 days in both control and treatment aquarium cultures. Following exposure to a sublethal dose of Ibuprofen, significant changes in the behavior of fish and disruption of normal physiology were observed. These changes were clearly displayed through nuclear degeneration, cellular edema, cytoplasmic degeneration, altered hepatocytes, formation of vacuole, increased sinusoidal space, altered central vein, and degeneration of sinusoid. These results indicated that the release of pharmaceuticals had a significant negative impact on fish health and highlighted deterioration in water quality and the ecology of water resources .
