Scientific advisor: dr. Szacsvai Kinga

Student: Stocker Walter

In the last years the environmental problems in indoor places, as houses, offices, schools became important. People spend almost 80% of their time in buildings. In our days, the life conditions, the different industrial pollutants present in the air can be harmful to the human health.

The objective of this study was to examine in six schools the air quality in the classrooms. The sampling points were selected as folows: schools to be found on main roads, in the center of the city surrounded by green spaces and in streets far from the center and characterized with less traffic. We measured the air temperature, relative humidity, the concentration of CO, CO2 and the flying dust in the air. The flying particles were measured in 10 litre of air according to the particle diameter (0,3μm, 0,5μm, 1μm, 2μm,5μm 10μm). The measurements were repeated every 15 minutes.

In every sampling site the location of the classroom, the type of window and the type of table, the ventillation rate in the previous break and the number of students were recorded. The results showed that during winter time the concentrations of  CO, CO2, and flying dust were considerably higher than in spring and summer.
