The dense black smoke was mostly carbon monoxide (up to 2,400 tonnes) and soot (up to 12,100 tonnes - about 9% of the UK's annual total).
Conventional technology for converting coal to liquid fuels breaks the coal down into synthesis gas, which is mostly carbon monoxide with a little bit of hydrogen; the hydrogen and carbon are then recombined to produce liquid hydrocarbons, a process that releases carbon dioxide.
For the last decade, the Eagle Pass shelter mostly used carbon monoxide.
The storm has been blamed for 27 deaths in Kentucky, mostly from carbon monoxide poisoning from generators.
Long-term animal experiments run mostly on small rodents give evidence of little effect of the pathological actions of dilutions such as those encountered in high polluted cities. However the acute toxicity of gasoline exhaust emission is well known and mostly due to carbon monoxide.
Imports of the popular tuna fillet (mostly frozen tasteless smoked and carbon monoxide treated products) also increased by 15percenttoto 16 000 tonnes during this period.
As the planet's initial crust solidified, volatile gases would be released to form an atmosphere that would contain water, later to become the hydrosphere; carbon gases, such as carbon dioxide, methane, and carbon monoxide; sulfur gases, mostly hydrogen sulfide; and halogen compounds, such as hydrochloric acid.
"In the atmospheres of the cold giant planets of our solar system, carbon is found as methane, unlike most exoplanets, where carbon has mostly been found in the form of carbon monoxide," said Mark Marley, an astrophysicist at NASA Ames Research Center.
Media captionBill McKinnon: "The plain is mostly solid nitrogen ice" New Horizons found the planum ices to contain mostly nitrogen, with limited amounts of methane and carbon monoxide.
Reductions in pollutant emissions occur mostly in soot, but also in nitrogen oxides and carbon monoxide, depending on the fuel and operating conditions.
Airborne nicotine, carbon monoxide (CO), PM3.5 (≤ 3.5 µm in diameter), and polycyclic aromatic hydrocarbons (PAHs) were used infrequently and mostly to complement PM2.5 assessment (n = 5).
