Decontamination of pesticides in soils

1969
The soil, as a medium for decontamination, offers a large number of processes by which organic substances can be destroyed. As such, progressive accumulation of organic pesticides would appear to be unlikely. Unfortunately, the chemical and physical properties of certain insecticides and herbicides afford them a degree of stability against the natural ...

Decontamination of Metal-Containing Soils

1995
Methods of removing metals from spoils derived from metalliferous mining were assessed as an alternative to traditional methods of land reclamation. Both enhanced gravity separation and chemical leaching were effective for oxidised spoils. The possibility of combined process routes in order to maximise metal removal are discussed.

In Situ Decontamination of Soil

Journal of Canadian Petroleum Technology, 1998
Abstract Methods for decontamination of soil in situ are receiving increased attention, as the requirement to clean these sites has become a national concern. The continual and costly liability is an important corporate incentive to clean contaminated soils.

Biotechnological Aspects of Soil Decontamination

2014
Soils have been subjected to several contaminants that vary in concentration and composition. Soil pollution causes significant damage to the environment and human health as a result of their mobility and solubility. Significant progress has been made in regulating soil pollution, with a parallel development of methodologies for soil assessment and ...

Ecological recovery of decontaminated soil.

1988
Once polluted soil is thermically cleaned up, a dead product is the result. However, the Dutch government emphasizes the so-called principle of multifunctionality of the soil. The most vulnerable function of the soil is the ecological function. To assess the possibilities of ecological recovery of cleaned soils, a field experiment was performed in a ...

Decontaminating soil with enzymes

Environmental Science & Technology, 1992
Xenobiotics are manmade compounds often introduced into the environment at concentrations that cause undesirable effects. They can be transformed as a result of biotic and abiotic processes, leading to changes in their chemical state and ultimately in their toxicity and reactivity.

Decontaminating soil organic pollutants with manufactured nanoparticles

Environmental Science and Pollution Research, 2016
Organic pollutants in soils might threaten the environmental and human health. Manufactured nanoparticles are capable to reduce this risk efficiently due to their relatively large capacity of sorption and degradation of organic pollutants. Stability, mobility, and reactivity of nanoparticles are prerequisites for their efficacy in soil remediation.

Chemical decontamination of PCB-contaminated soil

Chemosphere, 1997
PCB-contaminated soil was treated using the BCD (Base Catalyzed Decomposition) process to study the PCB removal performance of this process. NaHCO3 was augmented into the soil to reduce PCB concentration. It was found that PCBs underwent partial dechlorination and PCB degradation, during which organic matter in the soil performed as hydrogen donors ...

Applications of Bentonite to Soil Decontamination

Revista de Chimie, 2018
A calcium bentonite from Orasu Nou deposit (Satu Mare Romania) was used as raw material. We have conducted laboratory experiments to determine the influence of bentonite on the degree of heavy metal retention. It has been observed that the rate of retention increases as the heavy metal concentration decreases.

Non-Thermal Plasma Aided Soil Decontamination

Journal of Advanced Oxidation Technologies, 2013
AbstractLow temperature atmospheric pressure plasmas (LTPs) together with advanced oxidation processes (AOPs) are alternative to conventional chemical methods of soil decontamination. The processing of soil itself depends on several factors, like type of soil and pollutants, treatment technique, geological and atmospheric circumstances.
