چکیده

background foods are enriched with variety of chemical elements. some of these elements are necessary for human health. these elements enter in liquid, the cells and other organs, certain amount of these elements are essential for body organs to work properly. objectives this research was conducted to compare the level of lead and cadmium contamination in garlic species planted in ramhormoz and rasht and discuss about the source of this contaminations. materials and methods twenty composite samples were collected from each province, khozestan (ramhormoz) and gilan (rasht). each sample was burned according to instruction reported in aoac. then the white residue was dissolved in diluted nitric acid then the pb and cd contents were determined using graphite furnace atomic absorption spectrometer at 217 and 228.8 nm, respectively. no pb level was detected in garlic cultured in both cities. the mean concentration of cadmium was 0.40 and 0.58 mg/kg in garlics planted in ramhormoz and rasht, respectively. results statistical analysis showed significant difference between mean concentration of cadmium in rasht garlic and the permitted value (p < 0.001). the cadmium level in rasht garlic is much higher than the standard level. conclusions in order to test the reliability of the data obtained using this method, randomly selected samples were spiked with pb and cd standard solutions. the cadmium and lead recovery were reported 93.93 and 90.18 percent.
