Evaluation of the level of personal exposure to particulate matter PM 2.5 in short trips of school buses with Diesel engine

H Air pollution is a process considered an alteration generated by anthropogenic or natural causes. The impact of pollution occurs worldwide, generating consequences for human health and the environment [2]. In Bogotá, the District Secretary for the Environment (SDA), through resolution 2410 of 2015, launched the Bogota Air Quality Index (IBOCA) which allows knowing the air conditions and the risk that exists due to atmospheric pollution in the city through the calculation of the Air Quality Index (ICA) that takes data from the 13 stations located throughout the city in a fixed way [4]. The high costs to carry out mobile monitoring and the inexistence of exposure in private media promoted an investigation to acquire a device that will measure the concentration of PM2.5 with which the exposure of people was determined when taking university routes with a Diesel engine in short distances, to from which measures were proposed to reduce personal exposure to PM2.5 in the transportation system.
