Abstract | ||||
A total of seventy-five random samples of dairy products (15 each of raw cow's milk, raw buffalo's milk, condensed milk, baby formula, and milk powder) were collected from different markets and pharmacies at Damanhour, Behera governorate, Egypt. All examined samples were analyzed by Atomic Absorption Spectrophotometer to determine heavy metals residues namely such as Lead (Pb), Cadmium (Cd), Aluminum (Al), Chromium (Cr), and Nickel (Ni). The results obtained revealed that highly toxic metals lead (Pb) and cadmium (Cd) were detected above the recommended daily intake, While aluminum (Al), chromium (Cr), and nickel (Ni) were detected below the recommended daily intake as Lead levels in raw cow milk, raw buffalo milk, condensed milk, baby formula and milk powder were (0.11 ± 0.038 , 0.14 ± 0.040, 0.20 ± 0.049, 0.21 ± 0.052, and 0.27 ± 0.054), Cadmium levels were (0.03 ± 0.021, 0.09 ± 0.037, 0.11 ± 0.044, 0.12 ± 0.036, and 0.17 ± 0.046), Aluminum levels were (0.15 ± 0.078, 0.162 ± 0.062, 0.23 ± 0.077, 0.24 ± 0.086, and 0.26 ± 0.066), Chromium levels were (0.06 ± 0.05, 0.073 ± 0.04, 0.11 ± 0.046, 0.21 ± 0.062, and 0.20 ± 0.061), and Nickel levels were (0.00, 0.025 ± 0.015, 0.04 ± 0.03, 0.05 ± 0.023, and 0.093 ± 0.04), respectively. Public health significance of heavy metals was discussed. | ||||
