VARIABILITY OF MICROBIAL AIR POLLUTION AND DUST CONCENTRATION INSIDE AND OUTSIDE A SELECTED SCHOOL IN POZNAŃ
The article presents an analysis of the variability of air parameters quality realized in the two cycles measured (03.2013 and 11.2014). The measurements were made during 1.5 years in selected educa-tional building from the 70s. Measurements in each cycle research were carried out in two classrooms,...

| description | The article presents an analysis of the variability of air parameters quality realized in the two cycles measured (03.2013 and 11.2014). The measurements were made during 1.5 years in selected educa-tional building from the 70s. Measurements in each cycle research were carried out in two classrooms, before lessons and directly after they are finished and outside the building. The research included an assessment of the physical air quality (the air temperature, relative humidity, CO<sub>2</sub> concentration) and microbiological contamination (the general count of mesophilic bacteria, the general count of psychrophilic bacteria, the count of staphylococcus (<i>Staphylococcus</i>) mannitol positive (type α) and mannitol negative (type β), the count of <i>Pseudomonas fluorescens</i> bacteria, actinobacteria (<i>Actinobacteria</i>), as well as the general count of microscopic fungi). Additionally, air samples were taken to determine the concentration of dust in the classroom before lessons and immediately after their end. The quality of the physical air correlated with the abundance and activity of students in classrooms. The measurement results of microbiological contaminations were compared with the Polish requirements (PN), in order to classify the degree of air pollution as a function of microorganisms in 1 m<sup>3</sup> of air. On the basis of the measurements it was found that the analysed school physical air quality is unsatisfactory. Periodically, the acceptable levels of selected groups of microorganisms were exceeded. The measurement of dust concentrations showed that pupils’ activity inside the classrooms leads to secondary dust particles entrain. |
