Air quality in schools
Hromádka, Jiří ; Braniš, Martin (advisor) ; Hůnová, Iva (referee)
A lot of scientific articles were published about the indoor air quality during the last decade. It is proven that high concentrations of particulate matter and problems connected with poor ventilation conditions can cause health effects to people who are sensitive to them. Children are one of the groups at risk. They spend a lot of time at home and also at school, so the air quality at schools is an important issue. This work contains a review of scientific papers concerning this issue. It discusses the factors influencing indoor air quality, mainly concentration of particulate matter and carbon dioxide. Other factors were also chosen: the age of the school building and its location, the seasonality, the number and level of activity of pupils, floor carpeting and the amount of air circulation in the classrooms. The preliminary study tries to prove these theories. The concentration of PM10 and CO2, the temperature and the relative humidity were measured in three classrooms at one primary school in Prague. The results show that higher concentration of particulate matter is correlated with higher level of activity of pupils. Also poor ventilation leads to the higher concentration of carbon dioxide and poor air quality. It was proven that there is a minimal correlation between indoor and outdoor...

Air quality at school
Hromádka, Jiří ; Braniš, Martin (advisor) ; Hovorka, Jan (referee)
(EN) Thesis describes air quality in schools, its main factors of interest and according to the longitudinal study it suggests possible solutions for improvement. The study had been done in Kladská elementary school, Prague, Czech Republic, based on the findings obtained from the initial literature review. Although many scientific papers have been published mainly during last decade, there is a very limited amount of information concerning this issue within a longer timescale and a complex point of view is missing. The school environment was chosen because children are one of the groups at higher risk when adverse health effects caused by inadequate indoor air quality are evaluated. Aerosol particles and carbon dioxide concentration, temperature and relative humidity levels are important factors of interest in this case and all of them were included in the study. 8 measuring campaigns, each of them took 1 week, had been done throughout the whole school year. The main aim of these campaigns was monitoring and describing the variability of all selected factors during the day or year as well as between different classrooms. Average aerosol particles concentration (PM10) didn't exceed 70µg.m-3 during most of the campaigns and the pupil's activity was evaluated as the main influencing factor. The...
