Estimaciones de exposición personal a material particulado, níquel y cobalto en actividades de ciclorruta día domingo desde la calle 170 con 9 hasta la calle 116 con 15 en el tramo norte de la ciudad de Bogotá, Colombia

Abstract

This study aims to determine the degree of exposure to particulate matter and heavy metals in the bicycle lane, in the section between 170^th and 9^th Street and 116^th and 15^th Street, a road corridor that is characterized by being very busy in the urban context of the city of Bogotá, Colombia. The above, due to the high presence of vehicular flow during Sundays, since it is a road corridor used for recreation and physical activity by the users of the bicycle lane. Based on the above, measurements were made of the concentrations of particulate matter, nickel and cobalt, present on outbound and return bicycle routes. The monitoring period was carried out on Sundays from 27 February to 17 July 2022, from 9:30 a.m. to 11:30 a.m. using equipment as the Airbeam 2 and the GilAir 3 personal pump. A descriptive and exploratory analysis was carried out, identifying 2-hour average concentrations of PM10 of 7.73 ug/m3 and 6.6 ug/m3 of PM 2.5, which showed that there was no evident effect on the health of the population under analysis. No concentrations of nickel and cobalt were found in the PM10 samples in the filters obtained in the sampling.
