Background/Aim: Pupils and teachers spend a lot of their times at school, thus the poor indoor air quality at schools may cause adverse health effects, absence at school and adversely affect student performance. In addition, school environments are particularly complex and have a lot of different and interconnected factors having effect to occupants’ health. We aimed 1) to develop the real-time questionnaire (discomfort and symptoms) method and 2) to assess associations between measured (real-time measurements) and perceived (online-questionnaires about discomfort and symptoms) indoor air quality in school buildings.
Methods: Indoor Air Quality Police-project was conducted in six secondary schools with (4 schools) and without (2 schools) reported indoor air quality problems. Study involves six classrooms (6th- 9th grade) from each school where the measured and perceived indoor air quality were detected. Pupils and teachers completed the questionnaires in two weeks period at the end of the lessons in the studied classrooms. Following indoor air quality parameters were measured for two weeks periods: humidity, temperature, carbon dioxide, TVOC, ozone, arsine, ammonia, hydrogen sulfide, formaldehyde, particulate matter, dustiness, noise and lightness.
Results: The fieldwork was build up due the autumn 2016 and end at the March of 2017. Preliminary results will be present at the conference.
Conclusions: Indoor Air Quality Police-project will establish a new practice to assess the associations between measured and perceived indoor air quality. 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.
