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… Expand
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 stableExpand
Carbon monoxide production in photooxidation of organic molecules in the air
Sources and sinks of atmospheric carbon monoxide have not been in balance. The estimated rates of CO removal have been as much as a factor of two higher than estimated rates of emission. TheseExpand
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, andExpand
Sources of atmospheric carbon monoxide
Carbon monoxide (CO) is one of the main reactive trace gases in the earth's atmosphere: it influences both the atmospheric chemistry and the climate. In order to evaluate the atmospheric budget ofExpand
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. PhotochemicalExpand
Carbon---monoxide concentration in the Earth's atmosphere
Carbon monoxide (CO) is one of the main reactive trace-gases in the earth's atmosphere: it influences the atmospheric chemistry and the climate. In order to evaluate the global climatic effects ofExpand
Oxidation of carbon monoxide by bacteria.
In aerobic carboxydobacteria, the high concentrations of CO reduce the growth rate and cellular yield, thereby indicating that CO tolerance is a necessary part of the ability to use CO at higher concentrations. Expand
Sinks and environmental impacts for atmospheric carbon monoxide
Carbon monoxide is one of the main reactive trace gases in the earth's atmosphere: it influences the atmospheric chemistry as well as the climate. In order to evaluate the atmospheric budget forExpand
Carbon monoxide on the primitive earth
The reaction of CO + OH− in aqueous solution to give formate was studied as a carbon monoxide sink on the primitive earth and in the present ocean. The reaction is first order in OH− and first orderExpand
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. Expand


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 theExpand
Nonequilibrium of carbon monoxide and methane at the air-sea interface
Supersaturation of carbon monoxide was found in the surface waters of the Pacific Ocean on a recent cruise to Hawaii, which confirmed previous findings in the Atlantic. A diurnal cycling effect wasExpand
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 sinksExpand
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. Expand
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. Expand

A radical chain reaction is proposed for the rapid removal of carbon monoxide, leading to acarbon monoxide lifetime as low as 0.2 year in the surface atmosphere. Expand
The reaction of atomic carbon with oxygen: significance for the natural radio-carbon cycle☆
The nuclear reaction responsible for producing natural radio-carbon in the upper atmosphere, N/sup 14/(n,p)C/sup 14/, can be duplicated in an atomic reactor. When C/sup 14/ atoms so produced areExpand
Decrease of carbon monoxide mixing ratio above the polar tropopause
It is now established that CO is a regular constituent of the troposphere with mixing ratios ranging from about 0.1 t o 0.2 ppm in uncontaminated air (see e.g. the compilation of newest data byExpand
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. Expand
