Vural, Alaaddin
Soil samples collected from Demirören Alteration area, Gümüshane NE Turkey were analyzed for heavy metals by using Inductively Coupled Plasma-Atomic Emission Spectrometry and Inductively Coupled Plasma-Mass Spectrometry and the contamination level of heavy metals was assessed on the basis of Geoaccumulation Index, Enrichment Factor, Pollution Index and Integrated Pollution Index. The results indicated that, in comparison with background value of upper crust, soil samples in Demirören alteration area have elevated levels of metal concentrations as a whole. High Geoaccumulation Indexes and Enrichment Factors for molybdenum, lead, selenium, bismuth, cadmium and copper in alteration area indicated that there is a considerable amount of especially molybdenum, lead and copper pollution, which mainly originate from alteration in the area.

The objective of this study was to determine the potential environmental risks associated with the Kirkpavli (Old Gümüşhane in northern Turkey) alteration area by quantifying pollution in soil. The Kirkpavli (Old Gümüşhane) alteration area is situated at the south of the deposit with the same name of gold-silver-bearing lead, zinc, and copper in the southern part of the Black Sea Tectonic Unit (Eastern Pontides). In this study, 28 soil samples acquired from the alteration area were analyzed for contents of some main elements including lead (Pb), copper (Cu), zinc (Zn), cadmium (Cd), cobalt (Co), manganese (Mn), nickel (Ni), and arsenic (As). Contents of the elements in the area were determined, and high values were obtained such as 1,171 mg/kg for As, 12.4 mg/kg for Cd, 77.3 mg/kg for Co, 341 mg/kg for Cu, 1,172 mg/kg for Mn, 51.9 mg/kg for Ni, 3,725 mg/kg for Pb, and 880 mg/kg for Zn. Soil contamination was appraised on the basis of Geoaccumulation Index (Igeo), Enrichment Factor (EF), Pollution Index, and Integrated Pollution Index. The calculated results of Igeo, EF, and PI of the elements can be shown in descending order of parameters as As > Pb > Cd > Zn > Cu > Co > Mn. The parameters for some of these elements indicated extremely high contamination (Igeo > 5), extremely high enrichment (EF > 40), and high pollution (PI > 3). High Igeo, EF, and PI values of As, Pb, and Cd in the soil samples mean that soil pollution is typically associated with alteration area. Considering its location and the results of this study, the Kirkpavli alteration area is a significant source of pollution and may have ecotoxicological effects on terrestrial, groundwater, and aquatic ecosystems in the region.

The concentrations of heavy elements were studied in the soils and plants of Robinia pseudoacacia, along a highway passing through Gümüşhane City Center, Turkey. The aim of this study is to understand heavy metal accumulation due to dense traffic load, industrialization, urbanization, and/or geological features of the region. The assessment of the heavy metal accumulation of the soils is based on the Geoaccumulation Index and Enrichment Factor, and that of plants, is based on the Bioaccumulation Factor. According to the Geoaccumulation Index, soil samples were uncontaminated for Cr, Co, Cu, Rb, and Sr elements, uncontaminated to moderately contaminated for V, Ni, Ba, and Zn, and moderately to heavily-heavy contaminated for As. The contamination of soil samples changes from moderate-heavy-extremely contaminated degree for Pb. According to the Enrichment Factor; soil samples show, no enrichment-moderately-severe enrichment for V. Considering the Zn element, enrichment is in minor to severe enrichment. On the other hand, element enrichment is severe to very severe enrichment for As and that of Pb is minor to an extremely severe enrichment level. The data revealed that the soil in the study area is significantly contaminated for Zn, As, and Pb. Also, concentration levels of Cu, Fe, Mo, Ni, Sr, and Zn in the shoots of Robinia pseudoacacia at some location were determined as above and/or exceeded the upper limit of the normal range.
