Determination of Molybdenum Contents and Relation of Some Heavy Metals in the Soil of Meadow-Pasture Terraces Between Kırıkhan-Reyhanlı

Abstract

This study was aimed to determine the molybdenum content of meadow - pasture soil between Kırıkhan and Reyhanlı in Hatay province and to determine the relations of the molybdenum content with some heavy metals in the soil. For this purpose, two different depths (0-20 and 20-40 cm) representing grassland pasture lands and 80 soil samples from 40 different points were taken. Cadmium (Cd), Cobalt (Co), Nickel (Ni), Lead (Pb), Copper (Cu), Iron (Fe), and Molybdenum (Mo) contents were determined in the soil samples. The contents of the available Cd, Co, Pb, Cu, Fe, Ni and Mo of the soil were determined by reading the 0.005 M DTPA + 0.01 M CaCl2 + 0.1 M TEA extracts in the ICP instrument. The results of the research shows that the Cd contents of the soils are between 0.01-0.32 ppm; Co contents are from 0.01 to 4.97 ppm; Ni contents 0.00 to 20.00 ppm; Pb contents 3.00-67.00 ppm; Cu contents 0.26-7.48 ppm; The Fe contents are between 4.00 and 61.00 and the Mo contents are between 0.001 and 0.064 ppm. It was determined that there are significant positive relationships between Co, Ni, Pb, Cu and Fe contents of Mo in the soil. It was also determined that there are significant positive significant relationships between Cd and Co; Co with Ni, Pb, Fe and Pb and Cu, Fe and Cu and Fe. No heavy metal pollution was found when the heavy metal contents of the regional soils were compared with the limit values.
