Effects of Cadmium on Digestive Organs of Teleost Fish Ophiocephalus (Channa)
Journal Title: Universal Journal of Environmental Research and Technology - Year 2013, Vol 3, Issue 2
Abstract
Heavy metals and their salts constitute a very important group of environment pollutants. Since they are potent metabolic inhibitors of both terrestrial and aquatic plants and animals. The various heavy metals Zn, Cd and Cu are widely distributed and important as regard to their deleterious effects. Cadmium is a heavy metal and well known as a toxicant that could have an adverse effect on fish. The sources responsible for cadmium contamination are mainly of the anthropogenic origin, food; cigarette smokings are the most important sources of cadmium apart from water. The fish showed pathological changes in cadmium. Cadmium has induced marked pathological changes in fish gills, liver tissue of Channa punctatus exposed to cadmium toxicity evidenced marked pathological changes. Discrete pathological changes were noticed in the intestine of the fishes exposed to cadmium at different duration with the same concentration of 172 ppm. This paper explained about histopathological changes induced by cadmium on digestive organs of Channa punctatus.
