Mothball Ingredient Causes Cancer,
Government Says

WASHINGTON (Reuters) - Naphthalene, which gives mothballs and public
restroom deodorizers their distinctive aroma, causes cancer in rats,
U.S.
government researchers said on Thursday.

Rats who breathed naphthalene fumes developed cancer at a rate high
enough to worry scientists at the National Toxicology Program (NTP),
who
must now decide whether people have the same risk.

The rats especially developed rare cancers in the nose, the researchers
found.

``The rats in the study were exposed by inhalation, just as most people
are, in
doses comparable to some human consumer and workplace exposures,'' the
National Institute of Environmental Health Sciences, which administers
the
NTP, said in a statement.

The Occupational Safety and Health Administration (news - web sites),
Environmental Protection Agency (news - web sites) and other agencies
suggested the tests after some German workers exposed to naphthalene
developed cancers including larynx, gastric, nasal, and colon cancer.

The report was the 500th issued by the NTP using laboratory rats.

``Since NTP was established in 1978, its reports have changed how
substances are handled in occupational and home settings, and in the
more
general environment,'' it said in a statement.

Some chemicals restricted because of its tests include
tetrachloroethylene and
carbon tetrachloride, once used in home cleaning fluids; mirex, which
was
restricted in its use as a pesticide and fire retardant; benzene, an
ingredient in
gasoline, and phenolphthalein, once an active ingredient in most
over-the-counter laxatives.

``Unlike the old cliche that 'everything causes cancer', almost half
the
chemicals tested do not produce tumors in laboratory rodents, and with
a few
rare exceptions, chemicals that cause tumors or other diseases in
rodents
eventually are found to cause similar if not identical problems in
humans,'' the
NTP said.
