Abstract:

The study was carried out around the abandoned Etibank Tungsten Mine Work at Uludağ Mountain in Turkey. Uludağ Mountain is known as "Olympus Bithynicus" in mythology and is one of the highest peaks of the far north-west part of Anatolia. Mining activity in this area started in 1969 and continued for approximately 20 years. This study evaluates the elemental (W, Mo, Zn, Fe, Cu, Cd, Mn, Pb, Cr, Co, B and Bi) content of P. holosteum around the abandoned tungsten mine. Three sample sites were selected around the mine for soil and plant sampling. Two sites approximately 500 m from the mine were assumed to be unpolluted sites. The other site was selected from a waste removal pool (WRP) and was assumed to be a polluted site. The soil and different organs (roots, leaves and flowers) of plant samples were analyzed by ICP-MS to determine the elemental contents. The classic open wet digestion procedure was applied to the samples with 5 mL HNO3 and 3 mL H2O2 in a borosilicate glass vessel for the roots, leaves and the flowers of the plants. Kjeldahl digestion was used for the soil samples. The W, Zn, Fe, Cu, Cd, Mn, Pb, B and Bi contents were found to be higher in the soil samples from the waste removal pools compared with the samples from the unpolluted sites. The elemental composition of P. holosteum generally increased by the activity of the tungsten mine. The results indicated that P. holosteum may be considered a bioaccumulator species for W, Mn, Cu, Cd, B and Zn can be used as a bioindicator for these elements.
