INDOOR AIR QUALITY - CHEMICAL POLLUTANTS

摘要

Numerous scientific studies show that indoors are the source of potentially harmful substances called indoor air pollutants. They come from various sources. Selected indoor chemical pollutants concerning to indoor air quality, their sources and health effects are introduced in this paper. Indoor levels are often much higher than outdoor levels and most people spend the bulk of their time indoors. As indoor air pollution is relatively new problem, health and comfort problems are associated with it. Buildings may cause a lot of specific symptoms commonly referred to as the Sick Building Syndrome. The starting point for studies on constituents of the indoor environment is to realize that the problem to be solved is complex. Facing the number and variety of physical, chemical and biological pollutants in indoor environment we urgently need strategies to distinguish severe from less severe health hazards. In this paper indoor air chemical pollutants of East Slovakia are presented. Although it has not yet been determined how the various substances effect human beings when they interact. Main groups of pollutants as radon, nitrogen oxides and formaldehyde were subjects of our special interest. Our interest has been pointed to indoor chemicals concentrations from indoor air quality creation point of view.
