Urban Dust Monitoring From Ground Level to Last Floor

Urban air quality strongly affects the health of citizens. In recent years, much effort has been spent in improving air quality monitoring systems in order to provide detailed data that consider the variability over the whole urban area. In order to improve the spatial accuracy of the monitoring systems, wireless sensor networks and pervasive technologies have been exploited. However, these systems normally do not consider vertical variability. Nonetheless, in buildings, people at a high floor may breath air with different characteristics with respect to those at ground floor. The goal of this paper is to investigate the variability of the dust level according to the height. An experimental analysis has been conducted and the achieved results confirm the importance of height for air quality and people health and highlight the importance of further studies.
