Short summary
PFCAs are toxic contaminants that can form in the atmosphere when precursor chemicals are released and degrade. We calculate the capacity of different atmospheric environments to form PFCAs this way. Different environments have very different capacities to form PFCAs, with the atmosphere far from sources of pollution being much better able to make the more toxic PFCAs. While the chemistry involved has uncertainties, they are small compared to the differences between environments.
