With reference to perfluoroalkyl and polyfluoroalkyl substances (PFAS)

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?

1 and 2 only
2 and 3 only
1 and 3 only
1, 2 and 3

All three statements regarding perfluoroalkyl and polyfluoroalkyl substances (PFAS) are correct. PFAS are synthetic chemicals used in a wide range of products, leading to their presence in various environmental media, including drinking water, food, and food packaging. They are known for their strong carbon-fluorine bonds, which make them extremely persistent and resistant to degradation in the environment and biological systems, hence the term “forever chemicals”. Due to their persistence, they can accumulate in the tissues of living organisms, including animals and humans, through repeated exposure, a process known as bioaccumulation.
PFAS are persistent, bioaccumulative, and toxic substances (PBTs). Their widespread use and environmental persistence are major concerns for human health and the environment.
Exposure to PFAS has been linked to various adverse health effects, including immune system effects, hormonal disruption, increased cholesterol levels, and potential links to certain cancers. Regulations and efforts to mitigate PFAS contamination are ongoing globally.
