WHAT YOU REALLY NEED TO KNOW ABOUT
NANO
The nanotechnology experts I consulted all agree on the same
basic principles when it comes to nanotechnology -- don't panic.
Use your best judgment. Limit your exposure. And stay informed.
Surprisingly, that last point may be the most pressing.
"Polling data shows that 80% of the American public knows
little or nothing about nanotechnology," says Moore.
"We think it's probably closer to 98%, but that will change
as the industry grows."
As for limiting exposure, that piece of advice is good in
theory, but until the federal government mandates that
manufacturers label consumer goods that use any form of
nanotechnology, there's really no way for a consumer to find out
for sure. But there is a good place to start. If you're
interested in seeing a sampling of the consumer products
currently using nanotechnology, visit Project on Emerging
Nanotechnologies'
Inventory of Nanotechnology Consumer Products ( www.nanotechproject.org/inventories).
It lists more than 200 nanotechnology-based consumer goods --
far from a complete list, since manufacturers don't readily
disclose which of their ingredients are nano-engineered -- but
it's still the first of its kind that's available to the public.
As such, it's a great starting point for anyone looking to see
if the products they're familiar with use this technology.
In the world of sunscreens, your safest bet is to stick with
the tried and true types (creams and lotions). If the sunscreen
label says it's transparent, yet contains zinc oxide or titanium
dioxide there's a good chance that they're using nanotechnology,
so steer clear.
Beyond that, my only advice is to keep your eyes open, and
watch for nanotechnology to start catching more news headlines
soon, as more studies are completed. Look for labels to appear
on products saying they contain nanoparticles, and, when they
do, decide what that means for you. Be reasonable: As
Moore pointed out, golf clubs and tennis rackets currently use
nanotechnology, but they're low risk because exposure is minimal
-- it's not like you're eating them. As for things like
nanoparticle-enriched cooking oil, you may want to think twice.
As the old saying goes, it's better to be safe than sorry. And
never has that advice sounded better.
