  • PFOA is a relatively larger compound, and smaller “short-chain” PFAS that industry now more commonly produces and claims are safer were absorbed at higher levels – up to nearly 60% of one short chain compound dose was absorbed by the skin.

    “This is important because we see a shift in industry towards chemicals with shorter chain lengths because these are believed to be less toxic – however the trade-off might be that we absorb more of them, so we need to know more about the risks involved,” said study co-author Stuart Harrad.

    Oh nice. Well at least shorter chain PFAS degrade faster, but that’s a shit consolation prize.


  • Non-stick cookware isn’t a significant source of PFAS exposure because while technically a PFAS, PTFE is a stable polymer. This is important because you might have replaced your cookware and feel safe while not realizing that the sofa and the rug in your home are spewing PFAS in the air every time you brush against them. I threw out a nice sofa because of this. Furniture and carpets are the main source for residential PFAS exposure. Unless your water is super contaminated of course.













  • “at the expense of economic and social sustainability, [but] defending and promoting European production and safeguarding tens of thousands of jobs.”

    I mean, she’s right in general that the EU might not be taking care of the workers of the affected industries. But that doesn’t mean the way to take care of them is to halt the transition of the worst offending sectors. There’s no reason not to super subsidize the auto sector transition to make EVs in the EU other than ideology. The transition doesn’t mean dependence on Chinese EVs and jobless or downskilled auto workers.



  • The problem with smart light switches is that they sit on the AC path. This means they’re capable of starting fires. As a result you might want units that don’t have questionable designs or the cheapest relays inside. A proxy for that is being certified by a western certification organization. Something like UL, CSA, ETL, MET, TUF, etc. Both the certification and the grade of components used increase the price of such units. There are some cheaper certified switches too, but personally I wouldn’t install something that doesn’t carry the name of a North American (I’m in Canada) manufacturer on it. Leviton, Eaton, etc. And those are $50+. 😔
