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?
(a). 1 and 2 only
(b). 2 and 3 only
(c). 1 and 3 only
(d). 1, 2 and 3
Explanation:
PFAS are found to be widespread in
drinking water, food and food packaging materials. This is due to their
extensive use in various consumer products and their persistence in the
environment.
PFAS are not easily degraded in the
environment. The strong carbon-fluorine bond makes them resistant to breakdown.
Persistent exposure to PFAS can lead to
bioaccumulation in animal bodies. Due to their persistence and resistance to
breakdown, they can accumulate in the bodies of animals, including humans, over
time.
All three statements are correct.
