Multiple choice

Which of the following is NOT a potential risk associated with the use of nanomaterials?

  1. Toxicity to humans and the environment

  2. Accumulation in the body

  3. Increased flammability

  4. Enhanced biodegradability
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Enhanced biodegradability is not a potential risk associated with the use of nanomaterials. In fact, some nanomaterials are designed to be biodegradable for biomedical applications. Toxicity to humans and the environment, accumulation in the body, and increased flammability are all potential risks that need to be carefully evaluated when using nanomaterials.
