STUDY ON ENVIRONMENTAL GEOCHEMISTRY OF TOXIC ELEMENTS IN THE WEST AREA OF KHOY CITY TO THE RAZI BORDER

This study aimed to investigate the geochemistry of toxic metals in soil and sediments of the west area of Khoy city to the Razi border, in Western Azerbaijan province. Evaluation of environmental geochemistry of heavy metals in soils and sediments of Iran are not much. As can be seen in addition to the ​​geology and tectonic and constructive factors of the area, human factors and industrial activities also can cause the presence of heavy metals in soil and sediments in areas around that area.
Cluster analysis showed significant correlation between almost all elements (with the exception of cadmium, copper) in this study. It seems that there is a good agreement between the two used indicators Igeo and EF pollution intensity. Both used indicators showed severity pollution for cadmium, cobalt, copper, manganese, nickel, lead, vanadium, zinc and iron. And for the rest of the elements can not be matched due to the use of different basic environment (such as amounts of shale, shell values and background values).
