UNLABELLED The objective of the study was to measure the indoor air quality in classrooms with special emphasis on particulate matter (PM 10) and carbon dioxide (CO(2)) and the impact of cleaning and ventilation. MATERIAL AND METHOD PM 10 was analysed via gravimetric method and by laser beam technology. CO(2) was analysed by infrared sensors. Measurements were collected for 3 weeks; first week: "normal" cleaning (twice a week) and ventilation; second week: intensified cleaning (five times a… CONTINUE READING
