The Stability

Sediments are important in influencing changes and movements of the heavy metals in the aquatic environment. Heavy metals contamination of the sediments has negative ecological impacts on the environment. Therefore, economical, effective, and environmentally friendly remediation processes are needed. Purposes of the remediation are to reduce toxicity, bioavailability, and mobility of the metals from the polluted sediments. The remediations are developed using physical-chemical, biological and combination of both techniques. Physical-chemical techniques are carried out to decrease the stability of contaminated substances. Biological techniques or known as bioremediation are conducted through biological processes of plants, animals, and microorganisms. While the combination of both respective techniques, can produce maximum benefits and increase remediation efficiency.

Extrinsic Defects

Dolomite is one of the commonest minerals that abound in the formation of a number of geological conditions. And it is found in abundance in eastern Algeria, especially Ain Mlila-Wilaya of Oum El Bouaghi-Algeria. The analyzed sample of raw dolomite has been by various physical-chemical techniques. The constituents of these carbonates are Ca, Mg, C, O, Al, Si, Fe, Ba, F, and Sr, analysis by XRD, and Raman, show that in addition to CaMg(CO3)2, we may have calcium carbonate. The Photoluminescence analysis characterizes the intrinsic and extrinsic defects of this carbonate. Differential thermal analysis reveals the different transformations of this mineral during heating. Indeed several stages including the elimination of water, the departure of CO2, the formation of MgO, and finally the formation of CaO.

Seismic Tests

Geotechnical, physical, chemical, and mineralogical properties of the sediments of Ramón López Velarde Park were examined. The site is located in the ancient lacustrine zone of Mexico City. In situ tests included a resistivity survey, soundings with an electric cone, and cross-hole seismic tests. In addition, a continuous core was obtained for the upper 40 m. This core was extensively studied in the laboratory to determine the variation of mineralogy, pH, organic matter, cation exchange capacity (CEC), and structural features with depth. The information is unique with respect to previous studies which focused on specimens at a single depth. Results facilitate the interpretation of the deposit evolution, leading to the current properties of this unique lacustrine sequence.Key words: Mexico City, geotechnical properties, lacustrine sediments, physical properties, mineralogy, chemical properties.
