(A) They are extremely widespread and occur from tropics to the Arctic – True. Persistent Organic Pollutants (POPs) are indeed found globally, from tropical regions to the Arctic.
(B) They often accumulate in food webs and reach toxic concentrations – True. POPs tend to accumulate in the environment, and as they move up the food chain, they can reach higher concentrations, posing a risk to organisms at higher trophic levels.
(C) Volatile Organic Compounds (VOCs) are examples of POPs – False. While VOCs can be pollutants, not all VOCs are classified as POPs. POPs are a specific group of organic chemicals known for their persistence, bioaccumulation, and potential long-range transport.
(D) They are widely used as flame retardants and in deodorants – True. Some POPs, such as certain flame retardants, have been used in various products.
(E) Some chemicals used in making non-stick, waterproof, and stain-resistant products are categorized as POPs – True. Certain chemicals used in the production of non-stick coatings, waterproofing, and stain-resistant products, such as per- and polyfluoroalkyl substances (PFAS), are considered POPs.
