Question
Q87. 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?
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Answer: 4
Detailed Explanation
Explanation:
- PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances) are widely used in products such as:
- Non-stick cookware
- Water-repellent clothing
- Food packaging
- PFAS are known as “forever chemicals” because of their high resistance to degradation.
- Their strong carbon-fluorine bonds make them extremely stable in the environment, persisting for decades.
- PFAS accumulate in human and animal tissues over time because they are not metabolized or excreted easily.
