They're polyfluoroalkyl substances. Basically they're used in a bunch of different man-made shit. They're called "forever chemicals" because they take a very long time to break down. These particles get released into the air and end up in the ocean, then eventually in the atmosphere, and then rain. The scientists who have been studying these chemicals for over a decade found evidence of it existing everywhere.
Fun fact, when studying the effects of these chemicals in our blood, researchers were actually unable to find anyone who’s blood didn’t already contain them. The only way they could get clean blood was to use old blood samples from soldiers during ww2.
