The environment is never spared from the pollution which threatens its elements, in particular the soil, especially if it is in an industrial activity zone. because of its direct impact on human health and other living organisms, its preservation and protection have, therefore, become everyone’s business. In order to confirm it, this study has come to assess the concentration of certain heavy elements, such as cobalt (Co), manganese (Mn) and lead (Pb) in the surface soil of the area of Touggourt industrial activity, using the latest indicators of environmental pollution. the highest contamination factor (CF) values for cobalt, manganese and lead were 0.277, 0.008 and 0.292, respectively. While the enrichment factor (EF) values were 41.79 for cobalt and 50.49 for lead. The maximum value of the pollutant load index (PLI) was recorded as 0.133. According to these pollution indices, the results of this study have indicated that human effects or industrial wastes and traffic in particular were the sources of heavy metal contamination in the studied region.
