Bioremediation
Bioremediation
Bioremediation (pronunciation: /ˌbaɪoʊrɪˌmiːdɪˈeɪʃən/) is a process used to treat contaminated media, including water, soil and subsurface material, by altering environmental conditions to stimulate growth of microorganisms and degrade the target pollutants.
Etymology
The term "bioremediation" is derived from the Greek word "bios" meaning life, and the Latin "remedium" meaning restoring balance.
Definition
In Environmental Science, bioremediation is a waste management technique that involves the use of organisms to remove or neutralize pollutants from a contaminated site.
Types of Bioremediation
Bioremediation can be categorized into two main types:
- In situ bioremediation - This involves treating the contaminated material at the site.
- Ex situ bioremediation - This involves the removal of the contaminated material to be treated elsewhere.
Related Terms
- Bioaugmentation - A method of bioremediation that involves enhancing the ability of microbial communities to degrade pollutants.
- Biostimulation - A process that uses nutrients to stimulate local microorganisms to increase the rate of degradation of a pollutant.
- Phytoremediation - A subset of bioremediation where plants are used to remove, transfer, stabilize, and/or destroy contaminants in the soil and groundwater.
