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.

    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.
