Materials and Methods : Çonsidering the accumulative property of cadmium and lead in spinach and radish growing in sari suburbs, this research was undertaken. Dry ash method was applied for the preperation of the samples, and measures quantitatively with the help of flame atomic absorption spectroscope. Ône way variance analysis was used in order to compare the, mean presence of cadmium and lead, in four geographical vegetable growing regions (east, weeks, south, north)of sari.
Results : Statistically significant difference was observed between mean content of lead in spinach and radish in the above four geographic regions (P<0.05). But was not significant in case of cadmium. Lead had the highest content, which is more than the level of standarad Dfg ppm. The highest content of cadmium was observed in the vegetable growing in the south regions, which is more than the standard level of cadmium in vegetables (0.25 ppm), and is about the standard level in case of radish.
