| Popis: | Background and Objective: The contamination of agricultural crops with heavy metals due to soil and atmospheric contamination is a potential threat for their quality and their safety. Heavy metals such as Cd and Pb have been reported for their carcinogenic effects. The aim of this study was to investigate the lead and cadmium concentration in some of crops grown in Isfahan province, Iran. Materials and Methods: During two seasons (spring and summer), 80 samples of four different crops (20 samples from each crop) were randomly harvested from some of the agricultural lands of Isfahan province. After sample preparation, lead and cadmium contents were determined by atomic absorption spectrometry. Results: The average concentration of Pb and Cd were different in different crops. A significant difference (p0.05). Means comparison showed a significant difference for cadmium between beetroot and cabbage and also beetroot and onion (p |
