Determination of lead and cadmium concentration in some protected and unprotected agricultural products


Abstract in English

In this study, the concentration of Pb and Cd was determined in some agricultural products in order to compare this concentration and to know the capacity of these products to accumulate these two elements. The samples were digested by nitric acid and the elements were determined by the atomic absorption spectroscopy. The results showed that the concentration of lead and cadmium in protected products was less than the concentration in unprotected products, and the concentration of lead was more than the cadmium, these results can be explained by the extensive use of lead and the unprotected agriculture products were exposed to the air pollution more than the protected products.
