Soil sampling was performed of 18 points, which located near pollution sources. Heavy metal measured by ICP instrument. Arsenic, lead, chromium and cadmium were investigated, among them lead and chromium have the highest accumulation in the soil. Cadmium has a lowest concentration in 6th region soils. In this area heavy metal concentration is Cr>Pb>As>Cd. Rosemary is a plant that is found in many passages in the area. Heavy metals enter the food chain through the soil. Heavy metal transfer from soil to upper parts of rosemary has been studied. Rosemary has been used to study the transfer of heavy elements from soil to plants. Studies shown that heavy metals accumulate in rosemary leaves less than rosemary stem and the elements are absorbed through the soil.for removal soil contaminant Phytoremediation is a good choice.
