Epidemiological Bases for Possible Air Quality Criteria for Carbon Monoxide

Air pollution: Our ecological alarm and blessing in disguise

“…At present, our interpretation of these findings is that an association could exist between myocardial infarc tion case fatality rate and atmospheric CO pollution, but additional studies particularly of COHb levels in myo cardial infarction patients at the time of admission are required to draw any conclusions about causality [Goldsmith and Cohen, 1969].…”

“…In summary, the available evidence supports a migration and an urban factor as contributing in a minor way to the complex of causal factors affect ing lung cancer rates. The available evi dence has failed to support the hypoth esis that exposure to community air pollution is a causal factor [Goldsmith, 1968], Most claims of dire consequences from air pollution also convey the implication that airborne concentra tion of air pollutants have been and are steadily increasing with time. et aL, 1969], or that it is related to the cooling of the earth since the 1940's, or that it is anthropogenic and Pilat, 1969].…”
