Bioremediation Quiz

What are the two main types of bioremediation?

• Aerobic and anaerobic

• Natural and artificial

• Intrinsic and extrinsic

• In situ and ex situ

Which type of bioremediation relies on natural microbial processes?

• Ex situ bioremediation

• Accelerated bioremediation

• Intrinsic bioremediation

• Enhanced bioremediation

What is the primary goal of accelerated bioremediation?

• To excavate contaminated soil

• To manage subsurface conditions for microbial degradation

• To introduce exogenous microorganisms

• To minimize site disturbance

Which method involves injecting air and nutrients into contaminated soil?

• Bioaugmentation

• Bioventing

• Biosparging

• Landfarming

What is a key limitation of accelerated bioremediation?

• It is less effective with metal contaminants mixed with organic pollutants

• It is too expensive

• It requires excavation of soil

• It cannot be monitored

Which technique involves the addition of microorganisms to enhance degradation?

• Composting

• Bioaugmentation

• Biosparging

• Landfarming

What is the main purpose of phytoremediation?

• To inject nutrients into soil

• To excavate soil for treatment

• To use plants to clean up environmental contaminants

• To monitor pH levels

Which of the following is a technique used in ex situ bioremediation?

• In situ biodegradation

• Landfarming

• Phytoremediation

• Bioaugmentation

What does biosparging promote in groundwater?

• Excavation of contaminated soil

• Addition of nutrients

• Degradation of contaminants by aerobic bacteria

• Degradation of contaminants by anaerobic bacteria

Which of the following is NOT a type of phytoremediation?

• Phytotransformation

• Phytostabilization

• Bioaugmentation

• Phytoextraction
