TOKYO - Anyone who has pulled away from the dealer's lot in a shiny,
new sedan knows the seductive scent of fresh plastic, paint and
upholstery that evokes a rush of pride and consumer satisfaction.
But the unmistakable new-car smell may soon be heading the way
of the rumble seat: Recent research linking it to a toxic cocktail
of harmful chemicals is spurring efforts by Japanese automakers
to tone down the fumes.
Japanese manufacturers, including Toyota Motor Corp., have become
the first to set an industry-wide goal of reducing cabin concentrations
to within government guidelines.
The push could spur similar action by U.S. and European rivals,
making interior air quality an emerging auto safety issue.
"The industry in Japan as a whole has recognized the need
for this and is co-ordinating efforts," Toyota spokesman Paul
Nolasco said. "Cutting down on the things that lead to these
smells is only something that can be better for you."
The new-car smell emanates largely from chemicals known as volatile
organic compounds, or VOCs, that leach from glues, paints, vinyls
and plastics in the passenger compartment.
The fumes can trigger headaches, sore throats, nausea and drowsiness.
Prolonged exposure to some of the chemicals can lead to cancer,
though there's no evidence linking that to concentrations in cars.
Critics liken the problem to so-called sick-building syndrome,
which traces some illnesses to similar agents seeping from the walls,
carpets and fixtures of new buildings.
Just sitting in a new car can subject riders to toxic emissions
several times the limits deemed safe for homes or offices by some
health authorities, though the problem tends to dissipate after
about six months, according to a 2001 study by Australia's Commonwealth
Scientific and Industrial Research Organization.
"We find new car interiors have much higher VOC levels than
any building we've researched," research leader Steve Brown
said. "Ultimately, what we need are cars with interior materials
that produce lower emissions."
Japanese automakers are now trying to do just that.
Earlier this year, they agreed to cut cabin levels of 13 of the
compounds, including possible cancer-causing agents styrene and
formaldehyde, by 2007 to match Japanese health ministry guidelines
for air quality in homes.
The Japan Automobile Manufacturers Association initiated the drive
after tests found some models made by three of the nation's top
carmakers failed to meet government recommendations.
The industry group refused to identify which companies or models
were evaluated.
Automakers worldwide have been trying to reduce volatile organic
compounds for years.
But the Japanese effort marks the first time the industry has adopted
government guidelines, JAMA's Tatsuya Ota said.
Most of Japan's top five makers - Toyota, Nissan, Honda, Mitsubishi
and Mazda - are already rolling out cars in compliance and touting
the lower volatile organic compound levels as a key selling point,
a move that is likely to catch on globally.
"There is good potential for the Japanese to take the lead
in this field," said Koji Endo, and auto analyst with Credit
Suisse First Boston in Tokyo.
"People are starting to feel the VOCs are an issue, and the
new efforts are one advantage that they (Japanese manufacturers)
can claim."
Brown says he does not know of any government with volatile organic
compound guidelines for car interiors, but says matching building
levels is a good start. Japan's recommendations were adopted in
2002 to combat sick-building syndrome.
The U.S. Environmental Protection Agency sets no guidelines for
volatile organic compounds in non-industrial settings, though formaldehyde
is regulated as a carcinogen by the Occupational Safety and Health
Administration.
The Washington-based Alliance of Automobile Manufacturers, which
represents nine carmakers including General Motors Corp., For Motor
Co and DaimlerChrysler AG, says it does not follow the issue of
volatile organic compounds. DaimlerCrysler said it has no initiative
on the volatile organic compound-induced fumes.
Toyota, Japan's largest automaker, currently has six models on
the road that meet the new standards, while Nissan has four.
Honda's new Civic, unveiled this month, is that company's first,
while Mitsubishi will begin it's lineup with the "I" next
year.
All say they are on track to have all new models pass muster from
2007.
While some customers complain about the new-car smell, others cherish
it enough to have spawned a cottage industry in aerosol "new-car
sprays" to keep their rides smelling fresh from the factory.
"Some people are annoyed by the smell and some people love
it," Honda spokesman Takayuki Juji said. "This is not
just for Honda users, but for all users."
