Heavy metals (HM) are naturally occurring trace elements found in the aquatic environment. However, their concentrations have been elevated as a result of industrial waste, geological composition, agricultural practices, and mining operations. The many causes of pollution have an impact on the physicochemical properties of water, sediments, and biological constituents, hence exerting a detrimental influence on the abundance and quality of fish populations. Environmental pollution is a pervasive issue on a global scale, with heavy metals posing a significant difficulty as one of the most crucial pollutants. The advancement of industrial activities has resulted in a heightened discharge of toxins into the surrounding ecosystem. The presence of environmental pollution has been found to have detrimental effects on fish, leading to instances of poisoning, the onset of diseases, and in severe cases, mortality. The degree of absorption and accumulation of certain contaminants exhibits variation across many biological systems. In this research article we examine the effect of water pollutants especially arsenic on the tissues of gills of Labeo rohita F. Hamilton, 1822. The histopathological studies have a significant impact on the identification of fish disorders resulting from heavy metal exposure.
