Niveles de exposición personal de material particulado PM 2,5 y NOX, en la ciudad de Otavalo, mediante la construcción y calibración de un equipo de bajo costo

Abstract

The city of Otavalo is currently experiencing constant population and demographic growth, which is why it is having several environmental problems that have been encountered over time, one of them is the contamination by mobile sources caused by the vehicles that travel through the city and the traffic, have generated gas emissions resulting from the internal combustion of the engines, adding to this that not all vehicles comply with current regulations preventing vehicle inspection, for this reason a methodology will be chosen to analyze the levels of personal exposure of particulate material and nitrogen dioxides PM2.5 and NOx through the use of low-cost equipment, its operation lies in the composition of the NO2 and PM2.5 sensors installed in a single component that measures the concentrations from time to time and the data is stored in the form of a notepad, for which the objective of analyzing the levels of personal exposure is desired in order to verify ar what is the impact that is causing pedestrians, once the data was analyzed, it was clearly noted that between NO2 and PM2.5 the first result was the compound with the highest concentrations recorded throughout the study.
