DETERMINATION OF TOXIC HEAVY METALS IN PEANUTS

Abstract

Peanuts are currently one of the most important oil-seeds in the world, and the demand for this commodity is steadily increasing. In this study, the level of toxic heavy metals in peanut samples was determined. Peanut samples were collected from a Georgia farm and also purchased from local grocery stores. Samples were digested, filtered and analyzed for their cadmium and lead contents using graphite furnace atomic absorption spectroscopy. The analytical procedure was validated using a standard reference material. The results of this study indicated that the concentration of cadmium and lead in most peanut samples were found to be below the maximum limits of the various regulatory agencies.
