Abstract: Milk is called the balanced nutrient food in the human diet. Micronutrients and macronutrients were found abundantly in milk, but contamination of heavy metals can occur in milk and milk products. The present investigation was carried out to determine concentrations of lead, chromium and nickel in raw fresh milk, market pasteurized milk and powdered milk of different brands. A total of 80 raw milk samples of cows from the household lactating cows in Chittagong, Narayanganj and Dhaka, 36 powdered milk samples and 36 market milk samples from Chittagong were taken for analysis. Lead (Pb), Chromium (Cr) and Nickel (Ni) concentration in raw fresh milk was found 0.17 mg/L, 0.04 mg/L and 0.15mg/L respectively. Where in brand market pasteurized milk the concentrations of Lead (Pb), Chromium (Cr) and Nickel (Ni) were 0.02 mg/L, 0.11 mg/L and 0.17 mg/L respectively. In powder milk of different brand samples the concentrations of Lead (Pb), Chromium (Cr) and Nickel (Ni) were 0.18 mg/L, 0.11 mg/L and 0.17 mg/L respectively. A comparison of level of those three heavy metals was done with different locations of Bangladesh and among different brands. The levels of those three heavy metals within most of the samples were found within permitted range of different approved authorities. But in some samples those limit exceeded the limits which can cause health risk to humans. The way of their entry to the human food chain is through the contaminated milk and powder milk due to the presence of industries and highway roads near the dairy farms, animal feeds contaminated with heavy metals and processing steps.
