Non-industrial work place

The concentration of dust in industrial working places is often measured in milligram per m3 of air. In the non-industrial work place, however, the particle contamination is typically a hundred fold lower. Particles in the indoor air may be responsible when occupants experience acute health effects linked to their stay in a building. The cause of this condition is often termed the sick building syndrome (SBS), but this is not a clinical diagnosis, rather a combination of subjective symptoms. In only a few cases specific causes have been identified. The combined effect of several factors, among those dust particles, is more likely to explain the symptoms.

Dust from the non-industrial work environment, will often show a complex mixture of particles. The particle emission sources can be both internal (building materials, dust generated from paper, textiles, office machines, dandruff, hair, etc.), or originate from outdoor sources. The images show examples of particles frequently found in aerosol samples or in settled dust from these working places.
