Consider the following statements regarding per and Polyfluorinated Substances PFAS They are natural...........

Explanation:

Both statements are incorrect.
Per-and Polyfluorinated Substances (PFAS)

• They are hazardous man-made chemicals that spread globally in the atmosphere.
• They are used to make fluoropolymer coatings that can resist heat, oil, stains, grease and water.
• Products that use PFAs include clothing, furniture, adhesives, food packaging, non-stick cooking surfaces and electrical wire insulation.

Many PFAS, including perfluorooctane sulfonic acid (PFOS) and perfluorooctanoic acid (PFOA), are a concern because they:

• do not break down in the environment,
• can move through soils and contaminate drinking water sources,
• Build-up (bio accumulate) in fish and wildlife.

As a result of their proliferation, they pollute even the most remote regions of Earth.

• The PFA levels in the rainwater are above the prescribed levels all across the world.
• This phenomenon is especially problematic in a country like India, with a long history of rainwater harvesting.

Hence option 4th is correct.
