Biological responses to indoor air contaminants

Summary The scientific study of indoor air quality has been a topic for research in the last two decades; in the late 70's it became an issue of general public perception. The public perceptions have been such tremendous stimuli because they involve aspects of health and welfare (comfort and economics). Various biomedical studies were performed to evaluate adverse biological effects associated with ambient and occupational pollutants. However, it became obvious that humans were exposed more, on a temporal basis, to their normal indoor environments than they were either in the workplace or outside. Concern with biological contaminants was always an issue, but rarely examined indoors until recently. Biological responses to the indoor environment will be discussed in this paper.
