Investigation of Particulate Matters of the University Classroom in Slovakia

University students spend most of their time in classrooms that do not always represent an ideal environment for education. This is mainly due to the fact that most university buildings in Slovakia are old. Classrooms can be contaminated by various indoor pollutants, such as allergens, particles, volatile organic compounds etc. Indoor air pollution can lead to long-term and short-term health problems for students and staff but also can lead to decreasing productivity. It is therefore essential to deal with the monitoring of indoor environmental quality in universities in Slovakia and propose realizable measures to improve this situation. The aim of this study is to investigate the particulate matters. The measurements were carried out in the university classroom during lessons. These measurements were repeated during to lessons carried out once a week for the duration of one month. Handheld 3016 IAQ - device was used for determination of particulate matter concentrations. Air temperature and relative humidity was set with multifunction device Testo 435-4. Questionnaire survey based on subjective perception of indoor environmental quality was also performed during this study. Students fill in these questionnaires at the beginning and at the end of lessons. Analysis was used for investigation of occurrence of PM concentrations and subjective evaluation of students.
