Meaning and Definition
The use of living organisms, especially microorganisms, to break down and remove environmental pollutants from contaminated sites such as soil or water.
A branch of biotechnology that employs biological processes, including microbial degradation, phytoremediation (using plants), or mycoremediation (using fungi), to detoxify hazardous substances in the environment.
Dialectal Variation
British vs American Usage
Differences
Spelling and usage are consistent. The term is used identically in scientific and policy contexts.
Connotations
Carries positive connotations of sustainable, 'green' technology in both regions.
Frequency
Slightly more frequent in American environmental engineering and policy discourse due to the scale of Superfund site clean-up projects.

FAQ
Frequently Asked Questions
Composting is a form of bioremediation applied specifically to organic waste (e.g., food scraps, yard waste) to turn it into nutrient-rich soil. Bioremediation is the broader category that includes cleaning up industrial pollutants like oil, solvents, and heavy metals.
No. It is highly effective for many organic pollutants (e.g., petroleum, pesticides) which can be used as food by microbes. It is less effective or very slow for inorganic pollutants like heavy metals (e.g., lead, arsenic), though some processes like 'bioaccumulation' can help concentrate them for removal.
The timeframe varies widely from months to many years, depending on factors like the type and concentration of pollutant, environmental conditions (temperature, oxygen, nutrients), and the scale of contamination. It is often slower but less invasive than physical removal methods.
'In situ' means treating the contamination in its original location (e.g., in the ground or groundwater). 'Ex situ' involves removing the contaminated material (like soil or water) to treat it elsewhere in a controlled facility. 'In situ' is usually cheaper but harder to control.
The use of living organisms, especially microorganisms, to break down and remove environmental pollutants from contaminated sites such as soil or water.
Bioremediation is usually technical/academic in register.
Bioremediation: in British English it is pronounced /ˌbaɪ.əʊ.rɪˌmiː.diˈeɪ.ʃən/, and in American English it is pronounced /ˌbaɪ.oʊ.rɪˌmiː.diˈeɪ.ʃən/. Tap the audio buttons above to hear it.
