Since the industrial revolution, the intensification of polluting activities contributed to thecontamination of soil and it is extending to the planetary scale. Considering this phenomenon,some plants developed, the ability to accumulate contaminants in their tissues. Although it isonly very recently that phytoremediation which is designated as the techniques using plants toextract, degrade or immobilize contaminants present in the soil. The strong accumulation ofsalts in soils as well as in irrigation water greatly disrupts the growth and development ofalmost all plants. The study of its disruption in halophytes helps bring better guidance on thedeleterious effect of salinity and heavy metals.Our study on the phytoextraction of copper in saline soil by the halophyte plant Atriplexcanescans (push) nutt belonging to Chenopodiaceae family cultivated in a controlledgreenhouse of Mazagran station (Wilaya of Mostaganem). The experiment was conductedusing saline-based NaCl (0.5%) and 3% and copper sulfate CuSO45H2O (2000, 2500 and3000 ppm) separately and combined.The aim was to monitor and measure the influence and the effect of metal and salt stress onbiochemical and biometric parameter.The results showed that Atriplex canescens (push) Nutt is resistant to copper excess salinityup to 2000 and 3000pp; and 30g/l NaCl.It was also recorded as the metal salt and stress have led biometric disturbance significantlyaffecting the lengths of stems, leaf area and also the root volume and the concentration ofchlorophyll.While the study of the biochemical behaviour of the plant, the results showed an increase ofproline and soluble sugars in the leaf system and especially where a combination of the twosalts were used.
