Estimación de la exposición personal a material particulado (PM10 y PM2.5), plomo y manganeso en la ciclovía ubicada en Cra 7 desde la Cll 106 hasta las Cll 32, en Bogotá D.C durante el año 2022.

Abstract

The study determined the levels of fine and coarse particulate matter, lead and manganese in the bicycle lane of Cra7 between 32nd and 106th streets in Bogotá D.C. in order to make an approximation of the area's air quality. Airbeam equipment and a GilAir-3 pump were used for 12 days with an average of 2 hours of sampling per day. It was identified through the Airbeam that only one Sunday of the five studied registered maximum values per second of 679 µg/m3 and 292 µg/m3 for PM10 and PM2.5 respectively; on Tuesday maximum concentrations per second of 207,6 µg/m3 and 113,6 µg/m3 were registered and on Fridays maximum values per second of 148 µg/m3 and 83 µg/m3 were registered. As for the concentrations obtained with the GilAir-3 Pump vary from 45,7 µg/m3 to 47,2 µg/m3 on Sundays and weekdays with figures ranging from 65,6 µg/m3 to 212,5 µg/m3; these behaviors are caused by the high vehicular flow in the area. Therefore, knowing the air quality in the ciclovía is important given the massive influx of pedestrians who travel these streets to reach their homes, places of work and study. As for manganese, a value of 1,23x10^(-9)μg/m3 was recorded, which is a very low concentration in relation to the exposure time; for lead, no values were observed in the samples. Finally, the carcinogenic risk was characterized, inferring that the possibility of users presenting a risk of suffering from this disease due to the presence of manganese is very low.
