With reference to perfluoroalkyl and polyfluoroalkyl substances (PFAS) that are used in making many consumer products, consider the following statements:

  1. PFAS are found to be widespread in drinking water, food and food packaging materials.
  2. PFAS are not easily degraded in the environment.
  3. Persistent exposure to PFAS can lead to bioaccumulation in animal bodies. Which of the statements given above are correct?

B.2 and 3 only
C.1 and 3 only
D.1, 2 and 3
A.1 and 2 only

Correct Answer: Option D

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are synthetic chemicals used in many consumer products like clothing, carpets, furniture fabrics, adhesives, food packaging, and non-stick cookware.

Statement 1 is correct: PFAS are indeed widespread in drinking water, food, and food packaging materials due to their extensive use.

Statement 2 is correct: Known as "forever chemicals," PFAS are persistent in the environment and do not easily degrade.

Statement 3 is correct: Persistent exposure to PFAS can lead to bioaccumulation in animal and human bodies, as the intake exceeds the excretion rate over time.

Therefore, all three statements are correct.
