چکیده
|
Foods are enriched with variety of chemical elements . some of these elementsare necessary for human health . these elements enter in liquid, the cells andother organs , certain amount of these elements are essential for body organs to workproperly.objectives: this research was conducted to compare the level of lead and cadmium contaminationin garlic species planted in ramhormoz and rasht and discuss about thesource 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 instructionreported in aoac. then the white residue was dissolved in diluted nitric acidthen the pb and cd contents were determined using graphite furnace atomic absorptionspectrometer at 217 and 228.8 nm, respectively. no pb level was detected in garliccultured in both cities. the mean concentration of cadmium was 0.40 and 0.58 mg/kg ingarlics planted in ramhormoz and rasht, respectively.results: statistical analysis showed significant difference between mean concentrationof cadmium in rasht garlic and the permitted value (p < 0.001). the cadmium level inrasht garlic is much higher than the standard level.conclusions: in order to test the reliability of the data obtained using this method, randomlyselected samples were spiked with pb and cd standard solutions. the cadmiumand lead recovery were reported 93.93 and 90.18 percent.
