Biosensors: Using Biotechnology to Find and Fight Pollution

What is the primary function of biosensors in environmental testing?

• To measure the presence of a particular substance

• To create new pollutants

• To increase pollution levels

• To eliminate the need for laboratory tests

How long does it take for biosensors to provide test results at the site of pollution?

• About thirty minutes

• Several days

• A few weeks

• Several months

What is one advantage of using biosensors over conventional techniques for pollution testing?

• A) They are more expensive

• B) They require sending samples to distant laboratories

• C) They provide quick and accurate results

• D) They take longer to complete

What is an 'immuno-sensor'?

• A device that measures blood pressure

• A type of biosensor that uses chemical reactions produced by an animal's immune system

• A sensor that detects temperature changes

• A device used to measure air pollution

Biosensors help public health inspectors by (a)  

• By detecting hazardous material in
• By increasing the level of pollutio
• By creating new pollutants
• By eliminating the need for environ

What is the main benefit of using biosensors for environmental testing?

• They are more expensive

• They provide quick and accurate results

• They require sending samples to distant laboratories

• They take longer to complete
