Abstract :

Considering the importance of milk in our daily diet and the increased environmental pollutants, it is important to assess heavy metals in milk. This study seeks the idea of concentration of some heavy metals in packaging milks collected from 22 districts in Tehran. Moreover, the focuses on heavy metals are checked with the recommended permissible amounts. The samples are analyzed by pulsed ultrasonography and anodic pulse techniques. The polarography apparatus is used for this investigation. This device comprises of three workups of estimating, solubilizing, and clear qualities. Each time a cradle, test, and standard is included, these three stages finish. Each time including the above gauge, which is a similar bend underneath the chart, is plotted by the gadget. According to the program given to the device, the device repeats its work three times every 3 steps and adds buffer, sample, and standard. The ranges obtained from the mean Cd, Cu, Zn, and Pb correspondingly are in raw milk 0.099±0.116, 2.424±4.017, 4.990±6.244, 0.271±0.640 μg.ml-1, in packaging milk (pasteurized and sterilized) 0.049±0.037, 0.228±0.188, 0.999±0.873, 0.048±0.033 μg.ml-1 respectively. In almost all cases, concentrations of sub-metals allowed limitations and health concerns for milk and dairy consumption. The amount of all four heavy metals in raw milk was greater than that in pasteurized milk. This alteration was significant for Zinc, Lead, and Copper, but not significant for Cadmium.
