Abstract Air pollutants were liberated in a laboratory, and the decay of concentration was measured by standard methods during the return to equilibrium. Half-lives corrected for air leakage were as follows: hydrogen chloride 7 min; sulphur dioxide 40 to 60 min; smoke 145 to 300 min.

Contaminated indoor air began with soot from open fires on the ceilings of prehistoric caves, tepees, and hogans. Indoor air in the twenty-first century has developed its own distinctive pollution problems. Fifty percent of indoor air is generated from outside. Pollutants generated from indoor sources may be similar.

Human exposure to pollutants within home exceeds the recommended limits set by the World Health Organisation (WHO). Unfortunately, indoor pollution has not been given much importance although most people spend as much as 80–90% of their time indoors.

Indoor concentrations of pollutants often exceed outdoor concentrations, presenting a very real and dangerous health threat. Adverse health impacts of indoor concentrations of nitrogen dioxide from gas-fired stoves, formaldehyde from home insulation, benzo(a)pyrene from fireplaces, and radioactive radon gas that can be emitted from concrete, brick ...

People spend about 85% of their time indoors and an additional 3% inside vehicles. Therefore people are exposed to gaseous air pollutants and particulate matter from both outdoor (ambient) sources, through infiltration of outdoor air, and indoor sources.
