An analytical profile of heavy metals in the serum of crossbred cows rearing in automobile rich industrial area of western Maharashtra, India, was studied recently. A total sixty crossbred cows were selected randomly from the automobile rich industrial area in the present study. Precisely and precautionally blood samples (5 ml) were collected from jugular veins of each animal. Serum was separated and stored at -20 ºC until analyzed. The serum samples were analyzed for arsenic, cadmium, lead, mercury and nickel by using atomic absorption spectrophotometer (Model AAS-4141, ECIL, New Delhi, India). The serum levels of arsenic, cadmium, lead and mercury in animals rearing polluted area were remains multifold higher than levels of said metals found in animals rearing in pollution free environment. Hence it has been concluded that the industrial and automobile pollution resulted in increased level of serum arsenic, lead, cadmium and mercury in crossbred cows. The significance of analysis of heavy metals of the crossbred cows is having significant value in public health as these metals may have appear in animal food like milk and meat.
