Q. 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?

[A] 1 and 2 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: D
Notes:

Exp) Option d is the correct answer.

Statement 1 is correct. Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are synthetic chemicals that are widespread in the environment, including drinking water, food, and food packaging materials.

Statement 2 is correct. Chemically, individual PFAS can be very different. However, all have a carbon-fluorine bond, which is very strong and therefore, they do not degrade easily.

Statement 3 is correct. Persistent exposure to PFAS (per- and polyfluoroalkyl substances) leads to bioaccumulation in animals due to their chemical stability and widespread environmental presence.
