Abstract

A total of 100 samples including 50 samples of raw and 50 samples of PASTEURIZED MILK were obtained from dairy farms and one of dairy plants in SHAHREKORD area by Simple and Systematic Randomized Sampling. The ashes were obtained from the samples by using heat at 500°c, and then examined by potentiometric stripping analysis (P.S.A) method to determine the residual of LEAD and CADMIUM. One-way ANOVA and Pair T-test were used to compare the data and value of P<0.05 was considered significant. In these results, the mean concentration of LEAD (Pb) in RAW MILK and PASTEURIZED MILK were 60.72 ppb and 13.57 ppb, respectively. The mean concentrations of CADMIUM (Cd) in raw and PASTEURIZED MILKs were 2.87 ppb and 1.03 ppb respectively. In the samples CADMIUM residuals were lower than the standard level (0.01 ppm). Regarding the maximum permitted level (Codex 2000) of Pb in milk (1ppm), the concentrations of this heavily metal in the samples were lower than the standard level. In this study the mean concentrations of LEAD and CADMIUM in RAW MILK were higher than corresponding values in PASTEURIZED MILK (P<0.05). It means, the pasteurization process may reduce the concentration of LEAD and CADMIUM in milk.
