Spatial Variability of Heavy Metals in the Soils of Ahwaz Using Geostatistical Methods

Abbas Hani, Narges Sinaei, and Ali Gholami

Abstract—Heavy metals pollution and their toxic levels in soils is one of the major problems associated with the environment. Like other large cities, Ahwaz, in Southwest of Iran, is exposed to all kinds of environmental pollutions which pose serious problems for human health. A total of 50 soil samples were taken randomly from the surface soils in Ahwaz and the elements of cadmium and lead were measured. Geostatistic and non geostatistic methods were used to determine the spatial distribution. The probability maps were produced using Geographic Information System methods. On the other hand, the Radial Basis Functions is the best interpolation method for Cd and Pb with absoluteerrorof0.209. About 90percentof study area had more cadmium pollution than standard levels while Pb contamination in about 33 percent of the study area is more than standard levels.

Index Terms—Ahwaz, environmental pollution, geostatistics, heavy metals.
