Análisis de la exposición personal a material particulado, cromo y cadmio en la ciclovía dominical en el tramo de la avenida Boyacá desde la calle 170 hasta la calle 66

Abstract

This project was carried out by Av. Boyacá from 170th Street to 66th Street, one of the most important road corridors in the city of Bogotá, which exhibits a high flow of vehicles and is one of the preferred routes for Sunday recreational bike riders; for this reason the exposure to particulate matter, chromium and cadmium was estimated, by the use of bicycles, back and forth, in order to calculate the concentrations of pollutants, during 3 months from 9:30 a.m. to 11:30 a.m. Likewise, Airbeam2 equipment and the GilAir3 personal pump were used.

From the statistical and laboratory analysis, it was concluded that the average concentrations of PM10 (5.35 µg/m3) and PM2.5 (4.73 µg/m3) are not a significant risk factor for health, however, the use of mouth plugs is recommended, due to the presence of chromium (30.33 ng/m3) and SWP (32.21 µg/m3), which exceeded the maximum permissible limit in accordance with the regulations.
