Considers points including: ventilation and money, the best ways to control indoor air pollution, how much air is enough for ventilation, how far pollutants affect people, notes on asbestos and risks, industrial hygiene and "sick buildings", indoor air pollution vs outdoor air pollution.
Discusses the physical, chemical and biological effects that moisture can have on indoor air pollutants such as formaldehyde, radon, aerosol particles, minerals from concrete, ozone, nitrogen dioxide, polyurethane, microbes and organic vapours.
Notes increasing concern with the quality of indoor air, allied with the desire to conserve energy by minimising ventilation rates. Examines on the basis of a literature search the sources of indoor air pollution and the characteristics of the pollutants. Pays particular attention to tobacco smoke and its deleterious effects on health. Discusses minimum ventilation rates for rooms in which people smoke. Points out that ventilation alone cannot ensure that the strictest criteria for room air quality are met with smoking.
Notes that with increasing air quality standards, requisite environmental protection cannot always be ensured with existing air handling installations in industrial halls. Presents methods of improving performance using devices to monitor pollutant levels and to give enhanced ventilation. Points to deficiencies still obtaining in these fields. Provides examples of new air quality evaluation methods and plant concepts, which have been tested in practice, to illustrate their the recommended approaches and their application.
Discusses sources of formaldehyde indoors, e.g. smoking, formaldehyde resins, and release of formaldehyde from chipboards and foam insulation, and the importance of ventilation in removing excess pollutants. Factors influencing the amount of formaldehyde release include age of materials, temperature, moisture variations, ventilation. Emphasises the importance of quality control, standards and tests such as FTM-1 and FTM-2.
