In general, the PFOA used to help
make fluoropolymers is largely removed during the final steps
of polymer production and by the high temperatures used when
most fluoropolymers are made into finished products.
The U.S. Environmental Protection
Agency (EPA) reaffirmed in August 2004 that, "EPA
does not believe there is any reason for consumers to stop
using any consumer or industrial-related products."
Recent industry data indicated
the presence of PFOA at very low levels in samples of blood
bank supplies taken from various locations across the U.S.
In its risk assessment released January 12, 2005 (available
at www.epa.gov/opptintr/pfoa/pfoarisk.htm),
EPA estimated PFOA levels in the general population to be
approximately 5 parts per billion (ppb) - the equivalent in
time of a single second in a span of 6 years, 4 months.
Safety research continues, however,
and the fluoropolymer industry has been working cooperatively
with the EPA to identify possible sources and pathways of
exposure for PFOA. The U.S. Consumer Product Safety Commission
(CPSC) and the U.S. Food and Drug Administration (FDA) have
been consulted in this process. The industry also is taking
steps to reduce the potential for exposure, such as using
less PFOA, employing recycling and recovery techniques and
substantially reducing emissions from fluoropolymer manufacturing
facilities.
