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?

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

PFAS are found to be widespread in drinking water, food and food packaging materials.
PFAS are not easily degraded in the environment.
Persistent exposure to PFAS can lead to bioaccumulation in animal bodies.

Which of the statements given above are correct?

Select an option to attempt

Explanation

Statement 1 is Correct. PFAS are used in a wide range of consumer products, and due to their persistence, they can leach into the environment and contaminate water sources, food, and packaging materials.
Statement 2 is Correct. PFAS are known as 'forever chemicals' because the strong carbon-fluorine bond makes them highly resistant to natural degradation processes. This persistence leads to their accumulation in the environment.
Statement 3 is Correct. Because PFAS don't break down easily, they can build up in the tissues of animals and humans over time, leading to potential health concerns.
