Q. With reference to perfluoroalkyl and polyfluoroalkyl substances (PFAS), often called “forever chemicals”, consider the following statements:
1.They can be detected in drinking water, food items, and packaging materials.
2.They degrade rapidly in the natural environment.
3.Continuous exposure to them can result in their accumulation in the tissues of living organisms.
Which of the statements given above are correct?
Answer: C
Notes:
Explanation:
- PFAS are found widely in drinking water, food, and packaging due to their extensive use in consumer goods.
- PFAS are highly persistent and do not degrade easily in the environment, hence called “forever chemicals.”
- Long-term exposure leads to bioaccumulation in animal and human tissues, potentially causing health issues.
