Carbon Monoxide in Lower Atmosphere Reactions.
Environmental Sci and Technol 1971 Mar; 5(3):219-222
To understand more fully pollution problems posed by carbon monoxide, an experimental study of CO reactions in the lower atmosphere was conducted. The study involved exposure of CO to lower atmospheric conditions simulated in the laboratory and measurement of rate of CO oxidation in co2. To simplify analytical measurements, the CO reactant was mixed with c14-labeled carbon monoxide Results suggested that the CO oxidation rate in the lower atmosphere is approximately 0.05 percent per hour of day- or night-time, resulting in a lifetime of 0.3 Year; observed rates cannot be explained only by CO reactions with oxygen atoms and ozone; and the presence of CO at typical levels does not necessarily affect the process of photochemical smog formation.
