Multiple choice

Which soil remediation technique involves the use of microorganisms to break down and degrade contaminants in the soil?

  1. Phytoremediation

  2. Bioremediation

  3. Chemical oxidation

  4. Soil washing
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Bioremediation is a soil remediation technique that utilizes microorganisms, such as bacteria and fungi, to break down and degrade contaminants in the soil. These microorganisms can metabolize and transform pollutants into harmless substances, reducing soil contamination levels.

Multiple choice

Which soil remediation technique involves the use of chemicals to oxidize and break down contaminants in the soil?

  1. Phytoremediation

  2. Bioremediation

  3. Chemical oxidation

  4. Soil washing
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Chemical oxidation is a soil remediation technique that involves the use of chemical oxidants, such as hydrogen peroxide or ozone, to break down and transform contaminants in the soil. These oxidants can convert pollutants into less harmful or immobile forms, reducing soil contamination levels.
