Effects of some heavy metals on soil carbon mineralization in Osmaniye Organized Industrial Zone

In this study, it was determined some heavy metal contents [Cu, Mn, Fe, Zn (ppm)] in three soil samples from three different point of Osmaniye Organized Industial Zone which is observed to have been exposed to heavy metal pollution and one soil sample from Osmaniye Korkut Ata University campus which are not exposed to the heavy metal pollution. The effect of these metals on carbon mineralization (28° C, 45 days) was studied comparatively. At the end of the 45 days carbon mineralization determined by CO2 respiration method, [First area, 14.96 mg/C(CO2)/100 g DS] of the soil in sampled nearly the Osmaniye Organized Industial Zone Toşçelik Industrial Production Facilities was significantly lower than (P = 0,000) university campus soil [fourth area, 29.96 mg/C(CO2)/100 g DS]. The similarity were also observed among the carbon mineralization rates of four different soils and three different soil of the Organize Industrial Zone were found significantly lower than the campus soil (P = 0,000). It was a possible result that microorganisms living in Osmaniye Organized Industial Zone soils affected negatively from the current heavy metals.
