Abstract

Children are particularly vulnerable population for the presence of pollutants in indoor environment. Therefore, there is a great importance of air quality to the children health.  Outdoor air pollution, the way of interior ventilation, a large number of children in classrooms and their activities will also affect on air quality in schools. In order to evaluate quality of the interior air, set of measurements were conducted at six measuring points (in five classrooms and one outside) in an elementary school in the urban setting. This paper presents and analyzes concentrations of different physical and chemical pollutants in the indoor and outdoor environment: ozone, formaldehyde and nitric dioxide, volatile organic compounds, total suspended particles and particulate matters with different diameters (up to 2.5μm and 10 μm), and polycyclic aromatic hydrocarbon. Furniture construction materials in classrooms, as well as, walls and floors construction materials and paints affect the increase in the analyzed pollutants concentrations. Also, indoor and outdoor measurements of temperature, relative humidity and CO₂ concentrations were done.
