BookPublisher: 2016Description: 53p.Subject(s): Environmental SciencesDDC classification: 2751-T Dissertation note: Protein is one of the main ingredients of basic need of every human diet. Demand is more
than its production. This shortage is more in underdeveloped countries like Pakistan. Due to
industrial waste, many toxic heavy metals stay within the earth rather than its decomposition.
There is a cycle of circulation of these toxic heavy metals getting back into the tissues or organs
of grazing animals through feeds. (Nawaz, et al. 2015). These toxic heavy metals have no useful
impact on the body but instead, these cause extremely toxic effects even at their lower
concentration. In animal tissues bioaccumulation of heavy metals is hazardous to human health.
Heavy metals which are more likely to be present in animal tissues, are Co, Cr, Cu, Fe, Ni, Zn,
As, Cd, Hg, Pb (Javed, 2005). Other source of contamination is vehicle emission and dirty
slaughter places. Meat especially body tissues, organ of livestock i.e. liver, kidney and stomach
sold by shopkeepers on road side or at open market are more vulnerable for deposition of
metals. (Mariam, et al. 2004). The second source of protein is poultry which has shorter time of
production of meat rather than red meat animals. Its demand in world increases due to reasonable
prices and its nutritive property. (Mahmoud, et al. 2015). The other protein source is hen eggs
which contain a large number of heavy metals which is due to contaminated feed and polluted
water. But still, there are some traces minerals which is very beneficial and nutritive to health
(Rehman, et al. 2013). Last main source of protein is fish, which is more susceptible
contamination of heavy metal. Dangerous level of heavy metals has evident deadly or ceaseless
impacts on fish (Qadir, et al. 2011).
