Abstract
The investigation of pollution's elements were become the hot topics for the researchers. The current work aims to evaluate the concentration of some heavy elements Copper, Nickel, and Chrome (Cu, Ni, Cr) respectively. The study area of this research is Diyala province / Iraq. The base approach for this work is collecting 25 samples of soil to be studied. The samples were collected from (industrial, residential, agricultural) areas, with an average sample rate for each region with a depth (20 cm). After collecting the samples, they were sorted and compressed to prepare them for measurement by dispersive X-Ray Fluorescence. Analysis after obtaining the results, they are compared with the global determinants (WHO). Through these results, we find that a noticeable increase in the element (Ni) in Aleazim corking Khanaqin, Al-Rashidiya and Mohammed Sakran, while the highest concentration of (Cr) was recorded in jadidat alshat, Najana, Al -Rashidiya and Diyala Bridge. The (Cu) concentration was recorded high in the Aleazim Dam regoin, Aleazim, Muqdadiya, hayi Mezid, Al-Khalis, Rashidiya, Mohammed Sakran and Diyar Bridge. The residential and industrial areas were indicated an increasing in concentration of the investigated elements, while the areas with good vegetation have the lowest concentrations of these elements.
