The demand for the development of eco-friendly, sustainable, and adaptable technologies for the disinfection of the environmental contaminants is increasing nowadays. Nano-bioremediation is one such technique that has made possible the use of biosynthetic nanoparticles for soil pollution remediation. It is an effective, efficient, and feasible method for revitalizing soil potential and rendering it pollution free. Pollutants present in soil are a great threat to soil biota, environment, and in fact human health. Nanomaterials exhibit the unique chemical and physical properties because of which they have always received attention in the growing era of bioremediation. Use of nanotechnology for bioremediation is one such technology as it focuses mainly on the interaction between the contaminants, the microorganisms, and the nanomaterials being used for both the positive (i.e., stimulating) and negative or toxic environmental effects. Thus, this chapter focuses on the need to recover the polluted soil and application of nano-remediation technology for restoring soil's cultivation capacity.

Living Space

Groundwater is an important part of the human living space and supplies us with high-quality freshwater resources. However, the intrusion of any foreign matter into groundwater may cause groundwater pollution. Once this happens, clearing, control and remediation can be very difficult: not only does it need a lot of money, it is also technically challenging and time consuming. In view of current research on groundwater remediation in and out of China, we propose a package of groundwater pollution investigation, groundwater pollution remediation technology and groundwater pollution control processes with a view to providing theoretical reference for future groundwater pollution remediation efforts.

Initial Concentration

Electrokinetic remediation is in-situ remediation technique. Potassium dichromate was chosen as the pollutant and its initial concentration was 500mg·kg-1 in Kaolin soil. This experiment, we are to study the feasibility ,the factors which influence the whole course, including applied voltage, treatment time, soil moisture, OH- produced at the cathode and its control. It indicate that, there is separating out oxygen at anode, hydry at cathode. Cr2O72-and CrO42- absorb electron to change to Cr3+, and unite to Cr (OH)3. The experiment results show OH- produced at the cathode has crucial effects on the removal efficiency of chromium; secondly the applied voltage and treatment time have important influence on the efficiency, and the soil moisture affects the efficiency in some degree.

ABSTRACTThis paper discusses the formation of metal clusters on Xe buffer layers and the deposition of those clusters on GaAs, silica, and Bi2Sr2CaCu2O8 when the Xe is desorbed. These clusters contain hundreds to thousands of atoms, and their interactions with the substrate is different from that encountered when atoms are deposited directly. Since cluster assembly alters the reaction pathway at the surface, novel structures with unique chemical and physical properties can be stabilized.

Over Time

Fly ash, as a source of calcium, has potential for soil structure amendment. This potential was tested by examining the influence of fly ash on select soil physical properties of an easily clodded clay loam soil. Fly ash:soil mixtures were varied from 0 to 100% (vol/vol). Pots of these mixtures were placed into the soil of a reclaimed surface mine and sampled four times during a 15.5-mo period: upon mixing, after one summer, after one summer and a winter and after the second summer. Bulk density, dry aggregate size distribution, penetration resistance (PR) and modulus of rupture (MOR) were assessed on soils within the pots.Adding fly ash up to 25 to 50% generally increased bulk density; adding more decreased it. Bulk density decreased over time for most of the treatments. Adding 12.5 or 25% fly ash produced the greatest percentage of aggregates within the ideal range (0.5 to 4.0 mm). Blunt-end PR was a more sensitive parameter than cone resistance. Adding 25% fly ash resulted in lower MOR while maintaining a desirable level of aggregation, thus reducing cloddiness. In general most properties varied over time, indicating the need to consider the dynamic nature of them in reclamation. Key words: Fly ash, soil reclamation, bulk density, penetration resistance, particle size distribution
