Solution
The correct answers are:
- in the blood of nearly everyone in the United States
- found even in remote and pristine areas of the world
PFAs, or Per- and polyfluoroalkyl substances, are a group of man-made chemicals that have been in use since the 1940s. They are used in a wide variety of products for their resistance to heat, water, and oil. Due to their chemical structure, PFAs are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. Therefore, they are found in the blood of nearly everyone and even in remote and pristine areas of the world. They are not completely harmless as exposure to certain PFAs can lead to adverse human health effects.
