Abstract

This work is the subject of a study of the effect of Atriplexhalimus on the variability of the percentage of certain heavy metals in the region of Boukhadra-Ouanza north of Tébessa, which is characterized by the proximity of an ancient mining area and with different levels of salinity. Where we made field trips, the first to know the area and determine the sampling locations, and the second to take samples. The latter (soil surrounding the roots of the cut plant and soil without vegetation at a distance of one meter), then after we measured the salinity standards (electrical conductivity and the percentages of certain heavy metals. The samples were analyzed at the Geology Laboratory, Faculty of Nature and Life Sciences, University of Tébéssa, where soil CE calculated and compared to the percentage of heavy metals (zinc and copper) in the soil. The results showed the presence of a significant proportion of heavy metals such as zinc and copper, especially in the third study area, which is considered high by World Health Organization standards and to acceptable standards, because the latter is located near an abandoned mining area, unlike the high salinity factor in the first and second areas.
