Description
Characterization of the chemical composition and the source apportionment of PM10 at an urban background site in Bogota was carried out in this study. By using a PMF model, six factors were identified (∼96% PM10) including fugitive dust, road dust, metal processing, secondary PM, vehicles exhaust and industrial emissions. Traffic (exhaust emissions + road dust) was the major PM10 source, accounting for ∼50% of the PM10.
