Investigation of Heavy Metal Contents in Cow Milk Samples from Area of Merowe-Sudan. American Journal of Mechanics and Applications. Vol. 8, No. 1, 2020, pp. 21-24. doi: 10.11648/j.ajma.20200801.14 Received: April 6, 2019; Accepted: May 20, 2019; Published: March 10, 2020 Abstract: Cow’s milk is considered as one of responsible food sources contamination with heavy metals. The objective of the study were to assess to content of selected heavy metals in fresh cow's milk and its associated human health risks in the food chain in Sudan. Fresh cow's milk samples were collected from two dairy of Merowe city-North Sudan by using Atomic Absorption Spectrophotometer (AAS) was used for the quantitative determination of the concentration of sex heavy metals namely (Cd, Cr, Cu, Pb, Zn and Mn) in samples available, the elements of (Cd 0.007, 0.005, 0.008) (Cr 0.008, 0.009, 0.007) (Cu 0.500, 0.340, 0.460) (Pb 0.009, 0.006, 0.005) (Zn 3.120, 2.000, 1.640) (Mn, 0.120, 0.080, 0.160). These values are compared with Recommended Dietary Allowance (ARD) values and also with corresponding values of different countries available in the literature our result of this paper it is co strong to meager the concentration of seven heavy metals and show an important.

Introduction It is well known that increase in industrial and agricultural processes has resulted in increased concentration of metals such as Cu, Zn, Mn, Fe, Cr, Ni, Pb, Cd, Al, Se and Hg in air, water and soil. Such metals are taken in by plants and subsequently get accumulated in their tissues. Thereafter such metals get accumulated in the animals that graze on such contaminated plants and/or in the animals that drink polluted waters and/or inhale polluted air. Metals enter the human body through inhalation of polluted air, ingestion of polluted food and water or absorption through the skin [1]. Thus, large amount of these metals that are taken up by plants and animals subsequently find their way into the food chain. The scientific community is greatly concerned about the ever increasing pollution of the environment, especially about the intake of harmful metals by human beings, plants and animals. Heavy metals are persistent contaminants is the environment that can cause serious environmental and health hazards. They are released into the environment from natural and man-made activities. Some heavy metals (like Fe) are essential to maintain proper metabolic activity in living organisms; others (like Pb and Cd) are non-essential and have no biological role [2, 3]. However, at high concentration, they can cause toxicity to living organisms [4]. Lead is recognized as a known neurotoxicant with major public health concern which causes both acute and chronicintoxication [5]. The toxicity may show in the form of anemia, abdominal colic, liver dysfunction, renal damage, peripheral neuropathy in adults, CNS disorders in the form of permanent brain damage in children and in case of extreme lead poisoning, convulsion followed by coma and death, might occur. Moreover, lead has a biological half-life of about 27 years in human bones [6]. Cadmium intoxication in human results in renal damage and dystrophic changes with hypercalcuria, glucosuria, proteinuria and aminoaciduria with hypertension [7], and itai disease which is characterized by
