ABSTRACT
This study was carried out to determine the heavy metal pollution and possible sources of agricultural soils in Tavsanli district, Which energy power plant is located. Total 83 soil samples were taken and 8 (Cu, Cr, Pb, Co, Fe, Mn, Ni, and Zn) heavy metals were analyzed in soil samples The mean concentration of heavy metals were determined as Cu (32.89 mg kg-1), Cr (285.69 mg kg-1), Co (36.37 mg kg-1), Mn (860.20 mg kg-1), Ni (457.59 mg kg-1), Pb (22.14 mg kg-1), Fe (30,250 mg kg-1) and Zn (65.05 mg kg-1), were determined. The mean concentrations of Cu, Cr Co, Mn and Ni found to be higher than both the upper continental crust values and the European soil mean values. Contamination factor Co (2.1), Cr (3.10) and Ni (9.73), enrichment factor Co (2.73), Cr (3.75) and Ni (11.42) and geoaccumulation index Co (0.18), Cr (0.50) and Ni (1.98) values showed that the soils were polluted by Co, Cr, and Ni. In addition, it was determined that Ni (48.65) poses a "moderate ecological risk" in the study area. Pearson correlation anaysis and principal component analysis determined that Cr, Co and Ni have both lithogenic and anthropogenic origin.

The soil is the part of the biosphere where heavy metal pollution is most common. Heavy metals pose a threat to animal and human health through plants. This study aimed to evaluate heavy metal concentrations in the soil of orchards of Bilecik Province and possible human health risks. In 2016, 42 soil samples were taken from peach orchards of Bilecik Province, and Cr, Fe, Ni, Cu, Zn, Cd, and Pb analyzed. Pollution indices (Enrichment Factor, Geoaccumalation Index, Contamination Factor, Ecological Risk Factor) were used to determine heavy metal pollution, and the effects on human health were determined by the hazard quotient (HQ) and hazard index (HI). The study area is moderate contaminated by Cd (3.64), Ni (2.38) and Cu (2.24) in terms of enrichment factor. Similarly, the study area soils were moderately contaminated by Cd (1.72), Ni (1.40) and Cu (1.38) in terms of the contamination factor. Besides, soils had moderate potential ecological risk by Cd (51.54). The principal component and correlation analysis showed Cd and Cu are anthropogenic and Ni is the lithogenic origin. Although soil pollution indexes show moderate pollution, there is no non-carcinogenic health risk for children (0.56) and adults (0.061).

Soil is the basic component of the biosphere and is exposed to many contaminants, including heavy metals, which are mainly affected by natural and human activities. Heavy metals in the soil are included in the food chain and pose a risk to human health. Determination of concentration and potential sources of heavy metals and evaluation of environmental and ecological risks were aimed at this study. In this study, 79 soil samples were collected from Alpu plain, located in Middle Anatolian to determine concentrations of Cadmium (Cd), Chromium (Cr), Copper (Cu), Cobalt (Co), Manganese (Mn), Nickel (Ni), Lead (Pb), and Zinc (Zn). As a result, Enrichment Factor (EF) and Geoaccumalation Index (Igeo), average values of Ni and Cd showed moderate enrichment and pollution. Similarly, Cd was found as the considerably potential ecological risk. Principal component and Pearson correlation analysis proved that while Pb, Cr, Cu, Zn, Ni, Co, and Mn are primarily from natural sources, Cd is mainly from anthropogenic activities.
