摘要: Abstract Exposure to high levels of particulate matter (PM) can lead an increased risk development several diseases. In a city, ensure sustainable quality life for its population it is important understand the way measure and quantify PM exposure, especially in areas that be considered threatening. This paper defines method, which based on experimental data total amount inhalation terms physiological response pedestrians when different routes are considered. 10 2.5 concentrations were measured situ three with same origin-destination pair was obtained concentration, minute ventilation rates (obtained from heart rate values at time) time. The comparison made assuming one as reference (representing 100%) order avoid not only variability concentration due traffic but also climatic conditions. Results show main route (the shortest), highest volume, corresponds level inhalation. Nevertheless, , results did always suggest worst option despite average being undoubtedly higher this route. states non-representativeness value importance pedestrian effort (traduced by rates), combined manner, using second-by-second data.
