The present work undertaken in the environmental context aims to study the distribution of heavy metals in plants that grow naturally around uncontrolled landfills. The study's goal was to identify plants that can be used to remediate contaminated soils. For this purpose, 14 plants species and their rhizospheric soil samples were collected and analyzed for arsenic, cadmium, cobalt, chromium, copper, lead, nickel, and zinc by inductively coupled plasma‐atomic emission spectrometry. The results showed the presence of elevated metal concentrations in soil, many exceeding the regulatory values, and that many species exhibited an ability to accumulate multiple metals in their shoots and roots without sustaining toxicity. This was confirmed by bioconcentration and translocation factors generally higher than 1.

The study aims to perform the immobilization/stabilization process quality of ions exchange resins by cementation. For this purpose, three natural and local materials were tested as additions: (1) limestone, (2) marly clay and (3) marly limestone. After characterization of these additions, mainly by X-ray diffraction, the experimental study was initiated by the preparation of cemented packages according to two formulations. The first was carried out without addition and the second with addition. The second stage of the work was focused on studying the additions effects on the physicochemical properties and the mechanical behavior of the cemented resins packages. The obtained results showed that additions improve significantly the mechanical strength and the physicochemical properties of the studied packages. Local marly clay, rich in kaolinite and free silica, has made it possible, as a natural addition, to prepare the most efficient cemented resins packages.
