Abstract
Spatial mapping of the distribution of heavy metals was performed with the Inverse Distance Weighting technique (IDW) of Arc Gis 10 information system (GIS). We propose an innovative study based on information system technology and lichen biomonitoring to assess air pollution. The results demonstrated that the contamination of heavy metals (HM) fluctuates with certain some hotspots with high concentration of Cr, Pd, Cu, Cr and Fe. The spatial mapping showed that “SidiYayha El Gharb” is the most contaminated area not only lithogenically but also from industries and trafic. Spatial mapping that the environment is highly affected with industrial discharges, remediation activities should be carried out urgently to prevent an ecological disaster.
