Abstract : Nowadays, soil pollution is a very sensitive environmental problem and often phytoremediation is associated with it as a decontamination process. Phytoremediation is a set of techniques that use plants to clean up the environment. One of them, phytoextraction, exploits the hyperaccumulate properties of certain plants that can extract large quantities of heavy metals. The physico-chemical characterization of the soils before and after barley cultivation showed a significant decrease in heavy metal levels in the soils. The analysis of the plant organs of the tested biological material showed a strong accumulation of Iron, Zinc and Copper in its roots and leaves. It also showed the increase of biochemical parameters (total proteins and proline). The results obtained show that barley is a hyperaccumulator and has protective mechanisms that allow it to tolerate excess iron, zinc and copper. Hordeum vulgare L can therefore be used to rehabilitate soils polluted by Iron, Zinc and Copper.

Abstract : In recent years the main causes of environmental pollution come first on the production and use of various energy sources, then industrial activities that have become the major responsible for the degradation of ecosystems and environmental disruption. The pollution of soils begins to grow, especially at the level of agricultural land where it is very important in the socio-economic field of the developing countries, namely Algeria. For this reason, this research aims to know the effect of industrial discharges of the cement plant of Hadjar Soud on the quality of agricultural land in the municipality of Bekkouche Lakdar- Azzaba (Skikda); Of which we made a physico-chemical study on the surface layer (the arable layer) of these grounds to determine the quality and the fertility of these grounds as well as to determine the industrial impact of this cement factory on the latter. The physico-chemical results show that the soils of the commune of Bekkouche Lakhdar, Azzaba, willaya of Skikda (North-East of Algeria) are degraded and less fertile, and this is due to the irrigation waters which are affected by the discharges of the cement factory of Hadjar Soud. Therefore, it is necessary to control and treat the water, before irrigating the land and cultivation practices in order to avoid any type of pollution and contamination of soils and their degradation.
