Indeed the very first "science" on leaded gasoline was a study conducted by the bureau of mines, which concluded that leaded gasoline was entirely safe... Spoiler alert: It was not entirely safe. PFAs aren't even proven safe, they're just not-yet-proven-dangerous-in-small amounts, but that's so hard to measure it doesn't really assure us of anything.
