Paper Title
Heavy Metals In Vegetables Collected From Market Sites Of Isfahan, Iran

Abstract
The objective of this study was to detect the level of lead and cadmium residue in some vegetables in Iran. From May to September 2013 a total of 82 samples of vegetables including spinach, potato, cucumber, turnip, plum, eggplant, and carrots were collected from randomly selected retail outlets in Isfahan, Iran, and analyzed by the graphite furnace atomic absorption spectrometry. The mean recovery of the analytical method was 96.3% and 104%for cadmium and lead, respectively. The mean level of lead content obtained from 82 samples was 1.037 � 1.098mg/kg with a range of 0.070-6.940 mg/kg and for cadmium was 0.460 � 0.380 mg/kg with a range of 0.068-2.140 mg/kg, respectively. Lead and cadmium concentration in 51.2% and 74.4% of vegetable samples were higher than the maximum permitted level in the FAO and WHO(0.2 mg/kg for lead and 0.3 mg/kg for cadmium).The dietary intakes of lead (1.54-152.68 μg /day) and cadmium (1.50-47.08 μg/day) for an average adult through vegetable were well below the recommended tolerable levels of 214μg and 60μg, respectively.
