New Antarctic study shows levels of ‘forever chemicals’ reaching the remote continent have been increasing

New evidence from Antarctica shows toxic fluorinated forever chemicals have increased markedly in recent decades, with scientists believing CFC-replacements are a likely source. The most abundant chemical discovered was perfluorobutanoic acid (PFBA), which has been linked to human exposure and immune system impairment.
