Field measurements I Conducted in six secondary schools: - 4 with IAQ problems - 2 reference schools six classrooms from each schools  36 all together Questionnaire: 6th- 9th grade pupils and their teachers Two weeks period, at the end of the lessons Also paper questionnaires available Timetable: Autumn 2016 three schools Spring 2017  three schools

Field measurements II Two weeks: - humidity, temperature, carbon dioxide, TVOC, dustiness, noise and lightness (6 classrooms) - humidity, temperature, carbon dioxide, carbon monoxide, TVOC, ozone, arsine, ammonia, hydrogen sulfide, formaldehyde and particles (one classroom) Other: - Settle dust sample from surfaces - Vacuumed dust samples for endotoxin analysis - 8 liters active air sample - Air samples for characterizing microbes and bacters - Outdoor T, RH, particles and other parameters - Pressure difference between indoor and outdoor - Amount of income and outcome from all of the ventilation endpoints

…Symptoms

What new…? We have an opportunity to assess an information about possible indoor air related symptoms and discomfort simultaneously with real-time measured exposure factors… …Information has been collected from the same indoor air space and from the same people for several times… …There is potential to notice and determine new markers that are in key roles and have adverse effect on indoor air quality and on human …Indoor Air Quality Police-project will establish a new practice to assess the associations between measured and perceived indoor air quality.
