Variación espacial de las concentraciones de PM10 Y PM2.5 en las principales vías de la ciudad de Barranquilla

Urban atmospheric particulate material (PM) is a highly important pollutant due to the effects it generates on people's health and the environment. The presence of PM in urban areas varies spatially, so high or low concentrations can be found in different areas of the same city. In this study, a HAL-HPC601 particle counter and a Garmin Oregon 350 GPS were used at a height of 1.60 m in the execution of mobile monitoring to understand the dynamics of the particulate matter and identify hot spots on the main roads of the city of Barranquilla, 9 mobile monitoring were carried out in the months of July and August 2019, carried out on business days between 2:00 p.m. and 5:00 p.m. with a total distance traveled of 35.9 km, obtaining highresolution maps of the PM10 and PM2.5 concentrations along the monitoring route (Vía 40, Calle 30 and Avenida Circunvalar) to represent the spatial variability of PM concentrations. In concentration data analysis, outliers were identified through standard deviation analysis. The results show that the points with the highest concentration of PM10 and PM2.5 were recorded in Calle 30, an area with high traffic congestion, with average concentration results of 68.49 ± 54.28 µg / m3 for PM10 and 16, 66 ± 4.19 µg / m3 for PM2.5. This section of the road has the largest number of traffic lights and photo detection cameras. Particulate matter tends to concentrate on stretches of high-traffic roads in close proximity to likely sources, such as intersections, pedestrian crossings, slow-speed roads, and areas of vehicular congestion. Commercial and industrial areas are associated with high concentrations of particulate matter, it is likely that they are the result of the report in the set of fixed and mobile sources. However, since all the sampling was carried out on public roads, and very close to the source, some high measurements are attributed to traffic congestion and heavy vehicles.
