Abstract
Plant samples of Punica granatum (Punicaceae) were collected in Kunjirin which is located at north eastern of Sulaimani governorate, during Augest to September 2008. Punica granatum (Punicaceae) were collected, and the distribution of heavy metal content (Nickel, Cobalt,Zinc, and Manganese) in different organs (leaves, stems, and fruits) of this species analyzed .Also organic acid content(Citric acid, Fumaric acid, Malic acid, and Oxalic acid) in the plant were analyzed. Generally the results showed that there were significant differences of heavy metals among plant organs except (Zinc) . The highest total of heavy metal content were found in the leaves within the concentration 92.61 µg g-1 dry weight. The lowest level were found in the fruits with concentration of 50.84 µg g-1 of dry weight. The medium amount were found in the stem with 80.24 µg g-1 dry weight. The results showed that the amount of selected metals in the plant fruits were lower than in the leaves, and they were found in legally admitted limits and they can be consumed by human. Significant different distribution of organic acids were found among the plant organs. The highest total of organic acid was found in the fruit of the plant, with the concentration of 307.25 µg g-1 dry weight. The lowest level of organic acid was found in the stem (195.36 µg g-1 of the dry weight), the medium amount of the organic acid was in the leaves with the concentration 444.44 µg g-1 of the dry weight.
