The Impact of Jajarm Alumina Plant on Topsoil Contamination with Lead

Presence of heavy metals in different parts of the environment (such as, soil) has adverse effects on organisms’ health. The main sources releasing these pollutants to the environment are industries and mines. Therefore, in this study, the effect of Jajarm Alumina plant (located in North Khorasan province) on contamination of topsoil with Lead (Pb) around the factory, has been proceed.
Sampling of topsoil (depth Comparison of mean concentration of Pb in main geological directions of the factory, showed a significant difference between them (p Overall, results showed that Jajarm Alumina plant has not a significant effect on topsoil contamination with Pb.
