Dr. Theodor Sterling, of

Department of Computing

Science, is preparing an
exhaustive report for the
U.S. National Academy of
Science dealing with:indoor
pollution, "We tend to think
of pollution as something

Threats of oil shortages have
encouraged many people to
switch to. more plentiful
natural gas. However, recent
studies have shown that
cooking ‘with gas can
produce unacceptably high
levels of carbon monoxide.
In one study — published
recently, Sterling measured
carbon monoxide in Van--
couver homes. °

“tronically, the problem

placed on the butner. The
more burners used at one
time, the greater the = in-
crease in carbon monoxide
because the cooking vessel
prevents free air flow to the

“With energy shortages,
