Unlike air pollution outside, most publicized, the indoor air remained relatively unknown until early 2000. Yet, we spend on average in temperate climate, 90% of our time in closed envi-ronments, and a majority of that time in the home: home, work premises or to receive the pub-lic, means of transport, in which we can be exposed to many pollutants. The nature of these pollutants depends on particular characteristics of the structure, activities and behaviors (to-bacco, paint, etc.) and these pollutants can affect the health and well-being. The quality of indoor air is therefore subject of concern for many years and has emerged as a major public health issue.
Mold development and production of mycotoxins associated in some collective and individu-al buildings is likely to cause diseases, including allergic (rhinitis, asthma, skin and mucosal allergies). These dangers are of concern to susceptible populations (children, patients whose immunity is depressed, workers, etc…).
This study is based on the small town of Mikkeli in the region of Southern Savonia, specifi-cally the area surrounding the campus of the Mikkeli University of Applied Sciences. The quality of indoor air through the technique of Andersen sampler to collect and identify the different fungi and bacteria that may have a pathogenic effect on humans. According to Eu-ropean Union mold exposure standards, three sampling areas (P2, P3 and Y2) have a seem-like yeast contamination level above 50 CFU/m3 (First level of contamination: < 50 CFU/m3 – Very Low). Moreover, two sampling areas that exceeded the first level of contamination for Actynomycetes were observed (P3 and Mt2). Finally, the first level of contamination was also exceeded for molds on four different sampling areas (P3, Y1, Y2 and Y3).
