EXPECTED DECLINE IN CARBOXYHEMOGLOBIN LEVELS AS RELATED TO AUTOMOBILE CARBON MONOXIDE EMISSION STANDARDS

In most major U.S. cities, automobile emissions constitute the principal source of CO; in Chicago, according to EPA estimates, light duty vehicles are responsible for 69.3% of all CO emissions. Thus as new automobiles incorporating emission controls enter the automotive fleet and older, emission-uncontrolled automobiles are phased out, ambient CO concentrations should decline and corresponding reductions in blood carboxyhemoglobin levels of nonsmokers can be expected. In this article the projections of future COHb levels are based on the relationship, presented by Stewart, between carboxyhemoglobin equilibrium saturation at a barometric pressure of one atmosphere and parts per million CO inhaled in an atmosphere that is 21% O//2.
