In caves carbon monoxide can build up in enclosed chambers due to the presence of decomposing organic matter. [87] In coal mines incomplete combustion may occur during explosions resulting in the production of afterdamp. The gas is up to 3% CO and may be fatal after just a single breath. [75]
Toxic: a chemical that has a median lethal concentration (LC 50) in air of more than 200 parts per million (ppm) but not more than 2,000 parts per million by volume of gas or vapor, or more than 2 milligrams per liter but not more than 20 milligrams per liter of mist, fume or dust, when administered by continuous inhalation for 1 hour (or less if death occurs within 1 hour) to albino rats ...
Carbon monoxide can react with water to form carbon dioxide and hydrogen: CO + H 2 O → H 2 + CO 2. This is called the water-gas shift reaction when occurring in the gas phase, but it can also take place (very slowly) in an aqueous solution. If the hydrogen partial pressure is high enough (for instance in an underground sea), formic acid will ...
Gas appliances can lead to carbon monoxide poisoning. Never use a generator inside your home or garage, even if doors and windows are open. Only use generators outside, more than 20 feet away from ...
Plants are another natural source of hydrocarbons that could undergo reactions in the atmosphere and produce smog. Globally both plants and soil contribute a substantial amount to the production of hydrocarbons, mainly by producing isoprene and terpenes. [28] Hydrocarbons released by plants can often be more reactive than man-made hydrocarbons.
Leaks from the furnace, water heater, or other appliances can release invisible carbon monoxide into your home. Correctly installing an alarm can keep you safe. The Best Place to Put a Carbon ...
An old sewer gas chimney in Stonehouse, Plymouth, England, built in the 1880s to disperse sewer gas above residents. Sewer gas is a complex, generally obnoxious smelling mixture of toxic and nontoxic gases produced and collected in sewage systems by the decomposition of organic household or industrial wastes, typical components of sewage.
With the head and upper body placed inside the appliance, the concentrated carbon monoxide would kill quickly. [6] [7] Sylvia Plath famously ended her life with this method. Originally created as a by-product of the coking process, its use developed during the 19th and early 20th centuries tracking the Industrial Revolution and urbanization.
