EFFECTS OF AFŞİN-ELBİSTAN POWER PLANT EMISSIONS ON THE PHYSICAL, CHEMICAL AND BIOLOGICAL PROPERTIES OF NEARBY SOILS

Abstract

In this research, the effect of emissions of Afşin - Elbistan Coal - Fired Power Plant on the physical, chemical and biological properties of nearby soils was investigated. For this aim, soil samples were taken from the villages near the central and 30 km away through central in the dominant wind direction during two years and four different periods. Besides the physical and chemical properties of the soil samples, total and available S, Fe, Cu, Zn, Mn, Cd, Pb, Ni, F, urease, acid and alkali phosphatase and carbon diokside evaluation quantities were determined. It was found that, trace element and heavy metal contents of the soil samples taken from the dominant wind direction were higher than the soil samples taken from near central villages, especially concentration at sites closest to the power plant was much higher. On the other hand, urease, acid and alkali phosphatase enzyme activities of soils taken from the dominant wind direction of the central were decreased significantly (P < 0.05). Regreation analysis showed that negative correlation between the urease, acid and alkali phosphatase activities and all trace elements with the exception of iron, heavy metals, nitrate and CEC However, significant positive correlation were found between pH and organik matter of the soil samples taken from the dominant wind direction. There was no correlation between the CO2 evaluation and other elements in spite of negative correlation between CO2 and Mn, organic matter, clay content and CEC. There were negative correlation between the urease, acid and alkali phosphatase activities and CEC, N, correlation between the above-mentioned activities and pH and lime were positive of the soil samples taken from the near-central villages. However, it was obtained positive correlation between CO2 evaluation and pH, organic matter.
