Consideration of the steady-state equations for stable carbon monoxide and for radioactive carbon monoxide in the troposphere leads to the conclusion that carbon monoxide is produced at a rate of 5x1015 grams per year, a value some 25 times greater than the rate of carbon monoxide production from combustion. The concomitant residence time for carbon monoxide is 0.1 year, in agreement with a previous estimate of Weinstock. Hydroxyl radicals are shown to account for both the production of this… 
The global balance of carbon monoxide
Radioactive carbon-14 monoxide produced by cosmic ray neutrons provides a useful tracer to deduce the residence time of carbon monoxide in the troposphere. From the steady-state equations for stable
Tropospheric budgets for methane, carbon monoxide, and related species
A tropospheric photochemical model is presented that provides a homogeneous gas phase radical chain mechanism for the removal of tropospheric methane, carbon monoxide, molecular hydrogen, and
A general circulation model study of atmospheric carbon monoxide
The carbon monoxide cycle is studied by incorporating the known and hypothetical sources and sinks in a tracer model that uses the winds generated by a general circulation model. Photochemical
Oxidation of carbon monoxide by bacteria.
Carbon monoxide oxidation by growing cultures of Clostridium pasteurianum.
Growing cultures of Clostridium pasteurianum were found to oxidize carbon monoxide to CO2 at a maximal rate of approximately 15 nmol × min−1× mg protein−1, indicating that in vivo and in vitrocarbon monoxide is oxidized by the same system.
A temporal model of tropospheric carbon‐hydrogen chemistry
The numerical simulation of the troposphere including a nitrogen-oxygen-carbon-hydrogen atmosphere has been accomplished for homogeneous time dependent static chemistry, employing 30 species and


Carbon Monoxide: Residence Time in the Atmosphere
A lower limit of 0.1 year for the residence time of carbon monoxide in the atmosphere is derived from radiocarbon measurements, which can be compared with 2.7 years, a value deduced from estimated rates ofcarbon monoxide production and global measurements of atmospheric concentrations of Carbon monoxide.
The Source of Carbon Monoxide in the Float of the Portuguese Man-of-War, Physalia Physalis L
1. Carbon monoxide, 0.5-13%, is found in the float gases of Physalia . Oxygen comprises 15-20% of the total gas. Carbon dioxide is present in negligible amounts. 2. The gas gland, pneumadena, is the
The photo-chemistry of some minor constituents of the Earth's atmosphere
Summary Carbon dioxide and carbon monoxide: The rate of photo-dissociation of CO2 is appreciable only in the region above about 100 km. If local equilibrium prevails the carbon would occur mainly
The Stratosphere as a Chemical Sink for Carbon Monoxide
Abstract Past and recent data on atmospheric CO levels indicate no significant increase of average concentrations- despite the increasing anthropogenic emission rate-so that one or more natural sinks
The Ocean: A Natural Source of Carbon Monoxide
The surface waters of the western Atlantic are supersaturated with respect to the partial pressure of carbon monoxide in the atmosphere, and the ocean appears to act as a source of this gas.
Soil: A Natural Sink for Carbon Monoxide
Samples of various natural soils differed in their ability to remove carbon monoxide from the air, and Acidic soils with a high content of organic matter were generally the most active.
Natural Sources of Atmospheric CO
The source of atmospheric CO due to CH4 is comparable with, and may be larger than, that associated with the internal combustion engine, and it is argued that CO is more likely.
Carbon Monoxide Production by a Bathypelagic Siphonophore
A physonectid siphonophore, Nanomia bijuga, associated with a verticallymigrating deep scattering layer, has been observed with a gasfilled float at depths in excess of 300 meters in the sea. This
Hydroxyl Radical Kinetics by Kinetic Spectroscopy. VI. Reactions with Alkanes in the Range 300–500°K
Flash photolysis and kinetic spectroscopy were used to study the reactivity of OH radicals toward a representative set of alkanes. Previous studies have shown that OH radicals abstract H atoms from
