ABSTRACT
A suspension of very minute airborne particles with a biological origin is known as a bioaerosol. On average, a human spends 75–85% of their time in indoor occupations (e.g., educational institutes, working areas, medical facilities, public common areas, dwelling environments, etc.); thus, the indoor air becomes a very important factor for occupational studies. The level of that indoor concentration and the fates of biological particulate material present within the indoor boundaries may influence human health. The review study gives information about indoor occupational sources, concentration levels, and characteristics of indoor bioaerosols with respect to their significant effects on human health. Existing data on the combination of indoor air and its microbial load focuses on specific health effects caused by airborne bioaerosols. This review study gives information about the significant scientific basis for indoor air quality control and helps in emerging risk prevention programs for a person closely associated with the indoor environment. Important mechanisms that remove bioaerosols from indoor air include air exchange, active filtration, and deposition onto indoor surfaces. This review will contribute to identifying and quantifying indoor bioaerosol in different indoor occupations, especially for Asian countries. In addition, this chapter considers the use of various sampling techniques and adsorbents for sampling and controlling indoor bioaerosol concentrations.
