The Environmental Protection Agency is moving forward with approvals for pesticides containing “forever chemicals” as an active ingredient, dismissing concerns about health and environmental impacts raised by some scientists and activists.
This month, the agency approved two new pesticides that meet the internationally recognized definition for per- and polyfluoroalkyl substances, also known as PFAS or fluorinated substances, and has announced plans for four additional approvals. The authorized pesticides, cyclobutrifluram and isocycloseram, which was approved Thursday, will be used on vegetables such as romaine lettuce, broccoli and potatoes.

Are there any water filters that are proven to filter PFAS?
And what about irrigation water that is contaminated and sprayed on the organic crops?
I get the rich people hate, but this does feel like an issue that will impact literally everyone. Once something is in the water cycle it’s hard to get rid of it.
Even though, the burden of treating the side effects would be much less felt by the rich
Maybe but many eat at restaurants etc. I would actually expect rich people have relatively high baseline exposure outside affected communities.
There’s probably a spectrum but I would also guess you’re right about the exposure then
For filters with semipermeable membranes, like sea water filters, FPAS and similar molecules are way too big to pass.
Filtration of PFAS depends on the individual makeup of each chemical. The cross section of a organic fluoride containing compound is about the same as water so I would expect for chemicals without aromatic rings or branches a membrane would not be as effective and even then what’s happening is a time bomb where when these chemicals do eventually break down they break down into things that are harder to filter.
We should be blanket restricting organohalides except iodine based ones.
The very point with PFAS is that they don’t break down. At least not without serious energy input.
And membrane filters catch sodium chloride, which is way smaller than PFAS molecules.
Zero filters claim to filter PFAS. I don’t know if certified organic produce allows these chemicals to be used, but the organization that certifies food is also federal, so there’s no reason to trust it. I’m really hoping organic produce is safe from this. I would be able to get produce at Costco which is often both organic and affordable.
