Why measure it?
Formaldehyde gas (CH2O) is a flammable gas that enters the atmosphere through natural sources such as forest fires, by direct human activities, and via reactions between other compounds in the atmosphere. It is commonly sold commercially as a 30% solution in water for preservation purposes. It has a pungent irritating odor. CH2O in all its forms is highly toxic to all animals. Occupational exposure is mainly via the inhalation of vapors and can be known to cause headaches, difficulty breathing and burning in the throat.
Where does it come from?
Natural Sources
Most formaldehyde found in the environment is a result of processes taking place in the upper atmosphere. It is an intermediate gas which is produced during the oxidation of methane and can be used as an indicator of anthropogenic pollution and biomass burning. It does not accumulate in the environment as it is easily broken down by sunlight.
Industrial Uses
Formaldehyde is a precursor to more complex compounds used in several industrial applications. It is a commonly used in resins for the manufacture of composite wood products and plastics. CH2O solution is used as a disinfectant to kill most bacteria and fungi and can also be used to preserve tissues or cells for scientific analysis. CH2O enters the body through inhalation.
