FISH CANCER DEVELOPED BY ENVIRONMENTAL POLLUTANTS
Journal Title: International Research Journal of Pharmacy (IRJP) - Year 2012, Vol 3, Issue 10
Abstract
The pollution of rivers and streams with chemical contaminants has become one of the most critical environmental problems. Fish living in a polluted water reservoir use the contaminated water to rinse their gills; this results in the deposition of polycyclic aromatic hydrocarbons (PAHs) in the fish body. Contamination of foodstuffs by heavy metals such as arsenic, cadmium, chromium, nickel and lead has poses a potential carcinogenic threat to humans. Arsenic and cadmium appear to be the most harmful to the fish. Several cancers in fish appear to be the result of exposure to different environmental pollutants/chemicals. High frequencies of liver and skin cancers in brown bullheads are associated with high concentrations of PAHs and some metals in the environmental sediments. Taking these facts in view, the present article gives the emphasis on the fish cancer caused by various environmental pollutants, suggesting that fish species are truly suffer from different cancers/tumours.
