Toxic ‘forever chemicals’ found in pesticide used on millions of Mass. acres when spraying for mosquitoes
News
1 Dec 2020 | Boston Globe
Now, after years of criticism from environmental advocates who have long raised health concerns about the expensive treatment known as Anvil 10+10, the pesticide has been found to also contain an array of toxic compounds known as PFAS.

The high persistence of PFAS is sufficient for their management as a chemical class
Science
1 Dec 2020 | Environ Sci Process Impacts
We argue that this high persistence is sufficient concern for their management as a chemical class, and for all "non-essential" uses of PFAS to be phased out.
