Abstract

Field Magnetic susceptibility measurement has been carried out for various surface soil and sediments distributed in the industrial and agricultural zone of northern Tunisia, Mediterranean coast of North Africa. The spatial vatiation of magnetic susceptibility value is compared with that of the concentration of potentially toxic elements (PTEs) which are probably derived from anthropogenic activities such as industrialization and urbanization. There is a clear correlation between the variations of magnetic susceptibility value and PTEs concentration. It suggests us the magnetic susceptibility measurement is applicable for a low-cost and quick field screening of soil/sediment contamination.
