Scientists just found five new types of 'forever chemicals' (PFAS) hiding in killer whale blubber, and it’s way worse than we thought. These sneaky chemicals don’t show up in the usual blood or liver tests—they love fat instead. That means we might be seriously underestimating how much toxic stuff is building up in marine life (and maybe us). Time to rethink what’s really lurking in our environment! #Science #ForeverChemicals #KillerWhales
