Nowadays, soil pollution by heavy metals is a big concern for the environment, because of toxicity and stability also physiological effects on live organism.
Therefore it's necessary to assess the distribution of these elements to monitor soil pollution and maintain the quality of ecosystem.
Since there is no information about heavy metals distribution (Cd, Pb, Zn and Ni) in Atrush district soils in Duhok province, Iraq, this research is focused on spatial variability of heavy metals by geostatistic method in surface soils (0-25 cm) based on 15 soil samples by a randomized methodology of soil sampling.
Amount of available concentration of heavy metals by diethylenetriamine penta-acetic acid (DTPA) with some soil physical and chemical properties were measured in laboratory.
Average concentration of available heavy metals (mg/kg) were as follows: Cd (0.20), Pb (30.64), Zn (11.59) and Ni (1.73).
Results indicated that there was no heavy metals pollution in the soils.
Due to modelling spatial variability of studied parameters kriging method in GS+ was applied.
Results indicated that the concentration of all metals had strong spatial dependence (nugget semivariance < 25%) and the best fitted model for them was spherical.
Kriging maps showed all studied heavy metals were under normal levels and indicated the source of heavy metals is mainly from natural source of weathering parent material specially limestone
