Assessment of heavy metal pollution due to the Lead –Zinc mine at the Ain Azel area (northeast of Algeria)

The aim of this present study was assess the heavy metals pollution present in sediment of soil. The study identify the heavy metals contamination in the sediment samples collected in soils of Ain Azel area using Atomic Absorption Spectrometry (AAS).The heavy metals concentration in sediments samples ranged from (mg/kg ): Lead 10.45 to 94.79 , Zinc 8.13 to 89.79 , copper 8.30 to 21.73 , Chrome 5.12 to 21.46 , Cadmium 0.35 to 3.25 ,and Iron 12460 to 44190 .In our study , seven reliable indices such as Geo-accumulation, Enrichment Factor, Contamination factor, Contamination degree ,mead contamination degree, pollution Load index and Potential ecological risk index were applied to estimate metal pollution .The data generated were used to determine the quality of the sediments based on the enrichment Factor, Contamination factor, Contamination degree ,mead contamination degree, pollution Load index and Potential ecological risk index .
