AMES WARNS CARCINOGENS FILL ENVIRONMENT:
Expert links products to cancer
By SHELLEY WOLSON
Hair spray cans, hair dyes and even sunshine have
been found to be possible carcinogens, according to
national cancer expert Bruce Ames.
Ames, biochemistry professor at University of
California, Berkeley, spoke on "Environmental
Chemicals Causing Cancer and Mutations" to a stan-
ding room only crowd yesterday afternoon at the
Modern Languages Bldg.
AMES' LECTURE was part of the Donald John-
son lecture series which is sponsored by the Univer-
sity of Michigan Cancer Research Institute Commit-
tee'to honor publisher Johnson's continuing support
of cancer research.
Ames said there are a variety of carcinogins in the
environment which might be causing cancer by
damaging DNA. The widely used chemical vinyl
chloride for example, has been shown to be a car-
cinogenic in animals and humans. The plastics in-
dustry uses this chemical to make many products,
such as hair spray cans.
Ingestion of other harmful chemicals causes
mutations in DNA sequences of the cells, causing bir-
th defects. It also impairs cell DNA repairing
systems according to Ames. "If something happens
and it's not repaired right, cancer occurs," he said.
WITH A SLIDE presentation of detailed charts
and graphs, Ames explained how carcinogens get in-
to the human system how he and his research staff
tested for the information. He then discussed various
forms of cancer. "Skin cancer is a common disease
among fair-skinned people from getting too much
sunshine," he said.
Ames gave examples of familiar mutagens
(mutation causing agents' such as mustard gas, coal
tar and cigarette smoke. "And we know bladder can-
cer is much higher in cigarette smokers than non-
smokers," he said.
Hair dye is another popular mutagen. "Forty per
cent of our country's women are dying their hair,"
Ames said. Peroxide dyes appear to be the worst of-
fenders. In addition, pesticides and gasoline ad-
ditives, to which humans have a lot of exposure, can
Ames said some mutagens enter the body not
through industrial polution but rather through the
food we eat. Fat in the diet has been linked to colon
and breast cancer, he said.

NARITA, Japan (AP) - Protesters
who fought police for three days to
block the opening of Japan's new
billion-dollar Narita airport have won
another battle in their 11-year-old war.
Prime Minister Takeo Fukuda held
an urgent meeting with his cabinet
today and it was announced later that
the formal opening, scheduled for
Thursday, had been caicelled. Regular
commercial.flights were to start Mon-
day, April 3.
A spokesman said the action was
taken because control-tower equipment
was damaged by protesters Sunday and
there was the threat of more violent

They have vowed to fight until the air-
port is abandoned.
Early Tuesday, police ripped down a
65-foot steel tower that had been built
by protesters to obstruct theflight path
at the end of a runway.
The tower was atop a four-story con-
crete 'blockhouse held by airport op-
ponents. Police, protected by high-
pressure hoses, first used a crane to at-
tack the blockhouse and then tore down
Police had tried to capture the
blockhouse, which was built by
protesters on private property near the
runway, Saturday night but they were
driven back by a hail of rocks and steel
barbs fired from slngshots.
The opening of the new airport has
been delayed six years by rioting. Since
the airport was planned 11 years ago
five people have been killed, 1,800
