Abstract

Background and Objectives: HEAVY METALS are the most important environment pollutants, especially in high-density residential areas. The objective of this study was main purpose of this study was the determination of SPATIAL DISTRIBUTION patterns of HEAVY METALS (including Fe, Mn, Ni, Cr, Co, Pb, Zn, Cu and Cd) according to ORDINARY KRIGING method for the central parts of ZANJAN province, Iran.Methods: In this study the 241 of mixed samples of soil, picked up from 0 till 10 Cm depth based on Random Networking (Area of case study was around 2000 Km2). In order to, for investigating of the impacts of bedrocks on the HEAVY METALS, we sampled of eleven bedrocks. We used of Nitric Acid (5N), Atomic Absorption Spectroscopy and ordinal kriging for extraction, detection and finally, preparation of maps, respectively.Findings: The result showed the best models are Spherical models for the SPATIAL DISTRIBUTION of lead, zinc, nickel, cadmium, copper, cobalt, iron and exponential models for chromium and manganese respectively. The map of the SPATIAL DISTRIBUTION of metals showed that the distribution of iron, manganese, nickel, cobalt and chromium depend on geological formations. While it seems the concentrations of Pb, Zn, Cu and Cd were depended domestic and industry areas.Discussion and Conclusion: The highest concentrations of the metals were naturally detected in basalt and shale context with analyzing of bedrocks.
