WHAT IS "MICRO-REMEDIATION" OR "MICROBIAL REMEDIATION", WHICH IS A SPECFIC APPROACH TO SOIL REMEDIATION?
"Micro-remediation" or "microbial remediation" is a specific approach to soil remediation that uses microorganisms like bacteria and fungi to break down or contain contaminants. The term "miro remediation" appears to be a misspelling of this established environmental cleanup method.
Understanding the Terms
• Soil Remediation: This is the general practice of addressing and resolving contamination in soil to protect human health and the environment. This can involve a variety of physical, chemical, and biological methods.
• Microbial Remediation (Micro-remediation): This is a type of bioremediation that capitalizes on the natural ability of microbes (bacteria, fungi, etc.) to break down pollutants into less toxic or non-toxic forms like water and carbon dioxide.
Key Aspects of Microbial Remediation.
• Mechanisms: Microbes employ various mechanisms, including biosorption, bioaccumulation, and biotransformation, to mitigate the effects of heavy metals and organic pollutants.
• Contaminants: It is effective for treating soils contaminated with organic pollutants like petroleum or diesel oil (which contain polycyclic aromatic hydrocarbons) and, through different mechanisms, some heavy metals.
• Benefits: This method is often more cost-effective and environmentally friendly compared to conventional methods like excavation and landfilling, as it reduces the need for energy-intensive technologies and harmful chemicals.
• Related Techniques:
• Mycoremediation: A specific form of microbial remediation using fungi to degrade or isolate contaminants.
• Phytoremediation: Uses plants, often in conjunction with microbes in the root zone (rhizosphere), to remove, contain, or break down contaminants.
For more information on soil remediation techniques, the U.S. Environmental Protection Agency (EPA) website offers extensive resources.
