heal.abstract	Παρουσίαση πειραματικών δεδομένων έκθεσης παιδιών σε αιωρούμενα σωματίδια και υπολογισμός της εναπόθεσης σωματιδίων στο αναπνευστικό σύστημα με χρήση αριθμητικού μοντέλου	el
heal.abstract	The current thesis estimates the airborne particulate matter that is deposed on the respiratory tract of pre-school and school aged children. During the European research program SINPHONIE, measurements of the concentration of airborne particulate matter were carried out in different classrooms of two preliminary schools and one kindergarten at the city of Kozani. There were two periods of measurements, a warm and a cool season, for aerosols sizes ranging between to μm. These exposure data were then introduced into a mathematical model that estimates the dose in the respiratory system of the pupils. In particular, the model calculates the number of deposited particles per breath in the different regions of the respiratory tract (extrathoracic, tracheobronchial and alveolar) and takes into account the characteristics of the particles, the anatomy of the respiratory tract and the physiology of the breath. The results of the model were combined with the duration of exposure of children to the airborne particulate matter in order to calculate the average daily dose in the respiratory tract of the children in each school and for both periods of measurement. The experimental campaigns for the measurement of airborne particulate matter gave us the exposure for each classroom. In all cases, children are mostly exposed to particles with diameters greater than 1μm. In addition, exposure fluctuates during the day and this is mainly attributed to resuspension of the bigger (and heavier) particles when the children move around in the classroom. The results of the computational model showed that in all cases the dose is higher in the extrathoracic region of the respiratory tract. The number of deposited particles in the tracheobronchial and alveolar regions consists mainly of particles of small diameters; however the dose there is much smaller than that in the extrathoracic region. The average daily dose is equivalent in all schools during the cold period, whereas during the warm period the dose in the kindergarten is more than double of that in the preliminary schools, because in the latter the children spend their break outside.	en
