Abstract: Market requirement to peanut and deficiency of production in Iran lead to import of peanut from different countries such as China, Iraq and Sudan. This research studied heavy metal contamination of available samples of peanut in Iran market. Experiments carried out in 9 replication on different peanut after morphological separation. Pb and Cd measured by atomic absorption spectrometer after enzyme digestion. Results showed maximum Cd (70.83 ppb) in Iranian peanut sample and minimum of Cd (25.50 ppb) recorded in Iraq peanut samples. Maximum and minimum of Pb measured in Iraq and Iran peanut samples, respectively (1186.60 and 476.73 ppb).
