The areas for soil sample collection in Tikrit were selected based on several factors, including traffic movement, industrial and urban activities, and population density.

Soil samples were taken at a depth ranging from 0-15 cm from below the surface of the soil and old leaves of the Ziziphus plant for each site to estimate some heavy elements, including lead Pb , cadmium Cd, copper Cu and zinc Zn, starting from September 2019 to April 2020.

The Ziziphus plant was chosen in the current study because it is one of the most common plants found near streets of Tikrit, as it is one of the evergreen trees.
