Sarıkız tea (Sideritis trojana Bornm.) is an endemic plant and it has an economic value at local markets. It is used for antioxidant and antimicrobial purpose. Some villagers have an average income collecting and selling Sarıkız tea who live in piedmont of Ida mountain. This situation creates a pressure on this endemic plant’s population. Because of some restrictions sarıkız tea has begun to be cultured by some villagers. In this study, the natural grown and cultivated sarıkız tea was compared in terms of heavy metal contents. Three repetition and ten plants were used for experiments. Flowers and stem samples were ground after dry, prepared by the wet digestion method and plant nutrient contents were determined by ICP-MS. Mercury (Hg), cadmium (Cd) and silver (Ag) were not determined in none of these plants. Nickel (Ni) was observed only in summit stem samples. While tin (Sn) was higher in summit flowers than stems; cobalt (Co), antimony (Sb), chrome (Cr), arsenic (As) and lead (Pb) contents were higher in stems than summit flowers because of immobility. All heavy metals were observed higher in natural population than cultivated ones. In conclusion toxic elements aluminium (Al), lead (Pb) and arsenic (As) accumulations were determined in stem and flower very high level in natural population solely, it should be analyzed on hazardous for drinking long period. It is possible that bedrock of summit is rich in heavy metals. In a next study reason of these toxic elements accumulation should be examined.
