Publisher Summary The goals of air analysis are very diverse. They include continuous sanitary chemical monitoring of work zones, industrial gas emissions, technological processes, chemical survey under emergency situations because of chemical and environmental accidents, geological survey, chemical monitoring of fire- or explosion-prone works, and individual safety control. Besides gaseous components like carbon oxide, ozone, nitrogen dioxide, ammonia, and chlorine, it is usually necessary to monitor the concentration of vapors of liquids like acetone, benzene, chloroform, gasoline, mercury, and organomercury compounds, or of solid substances like aniline, and formaldehyde. Air analysis also includes determination by chemical methods and biological indicators of solid atmospheric precipitations like dust, microbiological pollution, and priority chemical pollutants including acids. The majority of hazardous substances in air are monitored by laboratory methods requiring sample collection followed by shipment to the laboratory for indoor analysis. This does not always guarantee effective measures for providing safe working conditions. Thus, the development of rapid, cheap, and simple methods, including rapid tests, is topical. Test methods can be in the form of indicator tubes, and pocket analyzers.
