    Enrichment of the consortium and the potential of it in bioremediation of phenanthrene contaminated soils had been proved in our previous study. The base of MSM was contained of the following (per liter): g MgSO H 2 O, g CaCl H 2 O, g NaCl, g FeCl H 2 O and 1 mL trace element by: In situ bioremediation experiments, conducted using hydrocarbon-contaminated soil treated with the combination of rhamnolipid and rhamnolipid-producing bacteria, showed that the inoculated Shewanella sp. BS4, along with the indigenous soil microbial community, supported the highest hydrocarbon-degrading bacterial population and soil respiration.

    Polycyclic aromatic hydrocarbons (PAHs) are a major pollutant class at thousands of contaminated sites. They are of great concern due to their genotoxicity, mutagenicity and carcinogenicity. Bioremediation is one of the commonly applied remediation strategies to clean up PAHs from the soils and the : Jing Hu.

This concept is also known as by: 1.

    Land Farming involves spreading excavated contaminated soils in a thin layer on the ground surface and stimulating aerobic microbial activity within the soils through aeration and/or the addition of minerals, nutrients, and moisture. It is useful in treating aerobically degradable contaminants (EPA ). SOIL RECLAMATION OIL SPILL CLEANUP HYDROCARBON BIOREMEDIATION: Bioremediation is an economical and safe method for cleaning up oil spills and bioremediating soils contaminated with petroleum hydrocarbons and dangerous organic compounds. The bioremediation process utilizes beneficial microbes, surfactants, micronutrients and bio .

Additional Physical Format: Online version: Bioremediation of contaminated surface soils. Ada, OK: U.S. Environmental Protection Agency, (OCoLC) The main scope of this book is to provide innovative methodologies for the in situ bioremediation of agricultural contaminated soils.

The book is set in three parts that collect 13 chapters Author: Juan C. Sanchez-Hernandez. In situ anaerobic bioremediation is an effective and well-proven remedial option to address chlorinated solvents in groundwater with minimal disturbance of the ground surface.

This technology can be applied to effectively reduce contaminant concentrations in the subsurface while allowing site operations to continue uninterrupted. COVID Resources.

Reliable information about the coronavirus (COVID) is available from the World Health Organization (current situation, international travel).Numerous and frequently-updated resource results are available from this ’s WebJunction has pulled together information and resources to assist library staff as they consider how to handle.

James G. Speight, in Reaction Mechanisms in Environmental Engineering, Bioremediation. Bioremediation is the use of microbial species to clean up soil and groundwater that has been contaminated by discharged chemicals (Chapter 8).The bioremediation process stimulates the growth of specific microbes that use the discharged chemical contaminants as a.

Biological processes, including microbial degradation, have been identified as critical mechanisms for attenuating organic contaminants during transit through the vadose zone to the groundwater.

On-site soil remedial measures using biological processes can reduce or eliminate groundwater contamination, thus reducing the need for extensive groundwater monitoring and treatment Author: J. Sims, Ronald C. Sims, J. Matthews. Final Report: Use of Vegetation to Enhance Bioremediation of Surface Soils Contaminated with Pesticide Wastes EPA Grant Number: RC Subproject: this is subproject numberestablished and managed by the Center Director under grant R (EPA does not fund or establish subprojects; EPA awards and manages the overall grant for this center).

Biological remediation of soils contaminated with organic chemicals is an alternative treatment technology that can often meet the goal of achieving a permanent clean-up remedy at hazardous waste sites, as encouraged by the U.S. Environmental Protection Agency (U.S.

EPA) for implementation of The Superfund Amendments and Authorization Act (SARA) Cited by: The regulatory and technical challenge is to use cost-effective control technologies that can treat complex chemical mixtures in contaminated soils and thereby reduce the resultant threat to human health and the environment.

Bioremediation can be such a by: 5. When soils are uncovered, small particles can become airborne with wind or other disturbance. Construction or demolition work, mining operations, or poor landscaping efforts can make soil dust. Breathing in contaminated dust may cause physical or chemical damage to humans.

For example, asbestos fibers can puncture the lungs. Chemicals such as.

During the past decades, the prevention of soil pollution and cleanup of contaminated soils have become a world-wide environmental priority.

The goal of soil bioremediation is not only to enhance the timely degradation, transformation, remediation, or detoxification of these pollutants by biological means, but also to protect soil quality. Bioremediation processes have been shown to be an effective method that stimulates the biodegradation in contaminated soils (McLaughlin, ; Swanell et al., ).

Biodegradation of hydrocarbon-contaminated soils (exploits the ability of microorganisms to degrade and/or detoxify organic contamination) has been established as an efficient. About two-thirds of the cases were at full-scale clean-up level with the remainder at pilot or laboratory scale.

Evidence for enhanced microbial degradation of xenobiotic chemicals in the rhizosphere, a zone of increased microbial activity at the root-soil interface, continues to accrue, suggesting that vegetation may play an important role in facilitating bioremediation of contaminated surface soils.
