    In nature, cyanide occurs in several species and fates, of which the free cyanide forms are the most toxic ones. Cyanide can be removed by chemical or biological processes. Biological treatment called bioremediation, which is cost-effective and eco-friendly, is the most applied process to remove cyanide from contaminated vassilyk.com by: 6. Remediation of Petroleum Contaminated Soils: Biological, Physical, and Chemical Processes provides exceptional coverage of information essential for the remediation of soils contaminated by petroleum products. Every aspect of in situ and ex situ bioremediation is discussed. Chemical and physical processes in current use are presented.

    Overview of ex situ decontamination techniques for soil cleanup Table vassilyk.comages and disadvantages of some biological technologies used in soil remediation (Castelo-Grande et al., ). Jul 07,  · In this paper results of pilot tests on bioremediation of soils contaminated with hydrocarbons are presented. In the area were established experimental fields where in-situ intrinsic biodegradation and in-situ engineered biodegradation processes have been studied.

Biological processes for decontamination of polluted soils by J. C. Mueller Download PDF EPUB FB2

Decontamination of polluted soils is a current challenge for scientists from various fields. Few data are available as concerns the soil fauna, and only one study included protozoa (Figure 9).Immediately after decontamination, active protozoa, nematodes, and collembola were not detected in treated soil.

Pollutants actually existing in various types of soil, ranging from rural, agricultural soils to urban or factory soils, belong to a wide range of chemical compounds, both organic and inorganic. The modern decontamination methods were each specifically designed for a particular pollutant.

Reagents and procedure conditions targeted only one particular contaminant, more rarely several pollutants Author: Yoshiharu Mitoma, Alina M.

Simion, Cristian Simion. Biotechnological Slurry Process for the Decontamination of Excavated Polluted Soils Article (PDF Available) · January with 31 Reads How we measure 'reads'. Decontamination of polluted soils by using bioaccumulative plants is proposed as an environmental-friendly alternative to the traditional physicochemical methods, being a sustainable method with a great potential in the terms of environmental protection and cost management.

the following phytoremediation mechanisms and biological processes Author: Mirela Nedelescu, Daniela Baconi, Miriana Stan, Ana-MariaVlasceanu, Anne-Marie Ciobanu. The book also discusses the increasingly important role of soils in enabling the preservation of life and contains a rare attempt to cross-harmonize the Soil Groups of the World Reference Base of.

Bioavailability of heavy metals in metal-contaminated soils depends on physical, chemical and biological factors. Physical (structure, penetrability) and chemical factors (Eh, pH, speciation, concentration) give the framework in which biological factors can modify the metal availability by release of oxygen, protons, and organic acids and by association with mycorrhizal vassilyk.com by: Summary.

To enhance biodegradation processes in the practice of bioremediation of contaminated sites, investigations into the optimization of enviromental conditions (e.g.

oxygen content, water content, temperature, pH-value) and processing modes (e.g. static or dynamic treatment, kind and amount of additives) are of great vassilyk.com by: 3. Müller, M. and vassilyk.com, H.,“Development of biological treatment for sanitation of soils contaminated with chlorinated hydrocarbons including the treatment of sanitation bound waste air— and water— produce using on site methods and the sanitation of contaminated groundwater and subsurface air Author: V.

Schulz—berendt. Anthropogenic activities, such as mining of natural resources, manufac-turing industries, modern agricultural practices and energy production have resulted in the release of heavy metals with resultant harmful im-pacts in some natural environments. Toxic heavy metals are harmful to living organisms even at low concentrations.

Therefore, heavy metal contaminated sites should be remediated as Author: Tania Rahman, Md. Ferdous Seraj. for decontamination strategies. Bioremediation, i.e. the use of living organisms to manage or remediate polluted soils, is an emerging tech- nology. It is defined as the elimination, attenuation or transformation of polluting or contaminating substances by the use of biological processes.

Initially, bioremedia. This book represents an overview of efforts to exploit biological and chemical processes to reduce the inherent risk associated with metal-contaminated soils.

It presents a comprehensive, up-to-date analysis of in situ immobilization and inactivation of toxic metals by. Persistent nature of most of the synthetic pesticides causes serious environmental concerns.

Decontamination of these hazardous chemicals is very essential. This review paper elaborates the potential of various biological agents in decontamination of agricultural vassilyk.com by: Bioremediation of soils polluted with diesel oil is one of the methods already applied on a large scale.

However, several questions remain open surrounding the operative conditions and biological strategies to be adopted to optimize the removal efficiency. Soil contamination or soil pollution as part of land degradation is caused by the presence of xenobiotics (human-made) chemicals or other alteration in the natural soil environment.

It is typically caused by industrial activity, agricultural chemicals or improper disposal of vassilyk.com most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons (such as. Because the concept of bioavailability incorporates multiple physical, chemical, and biological processes that affect the concentration and transformation of chemicals in soils, sediments, and aquatic systems, Chapter 3 describes these processes in greater detail and weighs their relative importance in certain envi.

Ex Situ Biological Treatment for Soil, Sediment, Bedrock and Sludge The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the.

For the degradation of pesticides and ultimate decontamination of polluted areas, biodegradation is becoming a method of choice. For the removal of hazardous chemicals from environment, the usage of biological agents (bacteria, fungi, and enzymes) is very efficient as Cited by: Groundwater remediation is the process that is used to treat polluted groundwater by removing the pollutants or converting them into harmless products.

Groundwater is water present below the ground surface that saturates the pore space in the subsurface. Globally, between 25 per cent and 40 per cent of the world's drinking water is drawn from boreholes and dug wells.

Potential of Biological Agents in Decontamination of Agricultural Soil. Decontamination of these hazardous chemicals is very essential. This review paper elaborates the potential of various biological agents in decontamination of agricultural soils.

The agricultural crop fields are contaminated by the periodic applications of vassilyk.com by: In situ biological treatment technologies are sensitive to certain soil parameters. For example, the presence of clay or humic materials in soil cause variations in biological treatment process performance.

Treatability studies are typically conducted to determine the effectiveness of. @article{osti_, title = {Bioremediation of contaminated surface soils}, author = {Sims, J.L. and Sims, R.C. and Matthews, J.E.}, abstractNote = {Biological processes, including microbial degradation, have been identified as critical mechanisms for attenuating organic contaminants during transit through the vadose zone to the groundwater.Report This report provides the results of an assessment to determine the decontamination efficacy of methyl bromide (MB) fumigant in inactivating Bacillus anthracis (B.a.; causative agent for anthrax) spores on materials typically found in subway system infrastructure.
