Reducing heavy metal (Zn, Cu) toxicity in a semi-arid area by halophytes

Abstract

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.
