Note:
PFOS and PFOA are a class of perfluorinated chemicals that
are best known for their use in the production of Teflon
and other stain resistent materials. The interest of the
FAN Pesticide Project in this issue is due to the use of
several of the PFOS and PFOA chemicals as "inerts"
in pesticides. However, most, but not all, have been deleted
from use since 2001. The so-called "inerts" used
in pesticides can account for as much as 99%, or more, of
a pesticidal formulation. US EPA's policy is to allow the
public information only on the "active substance"
and to deny the public the names of the chemicals used as
"inerts" in specific pesticide products -- even
though the majority of inerts are toxic and biologically
active.
