DuPont says it will phase out a chemical that is
used to make Teflon coatings for things such as pots and
pans. Rebecca Williams reports the EPA says the chemical
stays in the human body and the environment for a long time:


The chemical’s called PFOA or p-foah. An EPA science advisory board
has suggested that PFOA might cause cancer.


The EPA says it’s still deciding whether PFOA poses a significant
health risk. By 2015, the agency wants DuPont to eliminate any chance
of PFOA getting into the environment.


DuPont says it can do that. David Boothe is a global business manager
for DuPont:


“PFOA is present in the blood of the general population and that raises
questions that need to be answered. It’s important to note, though,
that DuPont believes that there are no human health effects known to be
caused by PFOA even though study of the chemical continues.”


Some environmental health activists worry that PFOA fumes emitted when
Teflon pans overheat might be more toxic than anyone is willing to
admit.

Chemicals Leak Into Microwave Popcorn

(sound of microwave popcorn)


Alright, I like microwave popcorn too, and I don’t like where this study is going, but the
Food and Drug Administration found that the grease-resistant coating inside microwave
popcorn bags can get into the popcorn oil. The coating is made with chemicals similar to
those found in non-stick pots and pans.


Tim Begley is a research chemist with the FDA. He was the lead author on a study
published in the journal Food Additives and Contaminants:


“A microwave popcorn bag is a very, very, very extreme situation, because of the heat
generated on a microwave popcorn bag.”


He’s talking about 400 degrees in just a minute or two. The chemicals used to make the
grease resistant coatings can break down into a suspected carcinogen known as PFOA,
but Begley stresses it is not known whether people are exposed to PFOA after eating a
bag of microwave popcorn. He says more study is needed.
