Abstract
The results of many different studies have demonstrated unequivocally that the quality of indoor air is often much worse than that of atmospheric air. The presence of dangerous chemical compounds in indoor air can have an adverse impact on human health and cause numerous diseases of the respiratory and circulatory systems. Such harmful chemicals get into indoor air as a result of their emission from building and indoor materials. In order to identify the source of emissions of organic compounds, miniature passive emission chambers, known as passive flux samplers, are being used on an ever larger scale. These instruments enable the passive intake of samples of analytes emitted from the flat surfaces of building materials and interior equipment. Such apparatus offers an alternative approach to time-consuming and labor-intensive investigations using expensive stationary emission test chambers. This article reviews different types of miniaturized passive emission chambers used to determine the magnitude of the flux of organic compounds emitted from the flat surfaces of various kinds of indoor materials.
