Pollution, cancer
link questioned

CHICAGO (AP) - Pollution of the
environment from such sources as
automobiles and chemical wastes has
not been shown to increase people's risk
of developing cancer, a panel of doctors
concludes in a report disputed by
several specialists.
But the report, in the current issue of
the Journal of the American Medical
Association, distinguishes between the
workplace and the general environ-
ment, and says that carcinogens like
asbestos and chromates in the work-
place may account for a future increase
in cancer.
THE AMA'S Council on Scientific Af-
fairs, which wrote the report, said there
has been no significant increase in can-
cer deaths that parallels the rise of
pollution in the last 30 years.
But some specialists called that con-
clusion premature and said several
studies have shown that some environ-
mental pollutants - including asbestos
- can increase the risk of cancer.
Dr. Richard Jones, a council mem-

ber, said in a telephone interview that
"a lot of people have implied auto
pollution and all other
pollutions ... that may be contributing
to the fouling of the environment are
probably causing all these cancers we
have."
BUT HE SAID that despite increased
pollution, particularly from the greater
use of chemicals derived from oil
products, there has not been a
significant increase in cancer during
the last few decades.
The report notes that there is a laten-
cy period of about 20 years between ex-
posure to a carcinogen and the ap-
pearance of cancer. But Jones said that
if the pollutants were causing cancer,
some signs should already be ap-
pearing.
He added, however, 'there are
probably some things in the environ-
ment that may still be found to cause
cancer."
ROBERT METCALF, a University of
Illinois biology professor and a con-
sultant to the World Health
Organization, said it is premature to
dismiss environmental pollutants as
cancer-causing agents. "I don't see how
anyone can say we've had time to find
out," he said.
