I’ve read more than a handful of articles on PFAS, but this one really underscored just how prevalent they are- concentrated in fish, dental floss, blood donations, shoes, food packaging, explosives, food, water, the air, etc. Not only does the sheer number of them concern me, but the fact that they will be difficult to replace in anything that needs to be waterproof, high temperature resistant, or perhaps airtight is concerning.
I am not sure. I do not think they have the direct harmful effect of some things. Not saying no effect. As far as I know it is that they do not break down fast which means any bad effect is going to linger and get worse the more we produce and use. It is not that they are everywhere… The question is are they at a significant concentration.
It was the long lasting persistence that was the unknown issue when all this started. Especially the higher molecular weight stuff.
I have not followed recently. So do not know. Keep in mind we put a lot of stuff into the environment much of it potentially not good. At some level this is just the one in the press now.
