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 sick building syndrome in office buildings. Poor ventilation is frequently blamed, although in 60% of cases, no specific cause can be identified, because of symptoms which are non-specific, and the vast variety of substances present in the air. Similarly, factors contributing to disease are not restricted to pollutant levels only. Procedure for examining causes of sick building syndrome are suggested. Describes checking of different kinds of ventilation system, and the importance of outside air intake. Describes problems of both local and central ventilation systems.
Describes briefly California's Indoor Air Quality program, the importance of safeguarding indoor air quality, effects of particles on health, particularly inhalable and respirable particles, indoor air quality problems such as'building related illness', the determinants of indoor air quality, mitigating measures, including ventilation, source removal or substitution, source modification, air purification, and behavioural adjustments to reduce exposures (avoidance).
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.
