Abstract
The use of conifers in forest phytoremediation
The study is carried out in the region of Ouled Yagoub, Noughis and the controls are
taken at the Chélia station, Wilaya de Khenchela, which focuses on the use of
conifers in forest phytoremediation. The species recommended in this study are and
Cedrus atlantica and Pinus halepensis. We carried out needle sampling of these two
species at the three stations to analyze the chlorophyll contents at the laboratory of
the Faculty of Nature Sciences and Life. Concentration variations between the
healthy control sample station and the two other stations considered us affected by
dust deposits have been found. The results revealed a high concentration of
chlorophyll in the Ouled Yagoub and Noughis stations, which are close to the barite
industry in the Ain Mimoun region compared to the levels in the Chelia station,
which is farther away from the source of barite. So, apparently, barite does not
negatively affect chlorophyll synthesis in the two recommended species, cedar and
pine, and the high chlorophyll content promotes phytoremediation and thus the
eventual use of these two species in the phytoremediation process.
