Resumen


Currently, studies in Latin American cities about emissions of PM2.5 and Black Carbon (BC) are limited. These pollutants are of special interest in urban environments, however, the lack of information about their emissions to the atmosphere establishes a challenge.

 

In the city of Manizales Colombia (390000 population and 2150 m.a.s.l.), the previous emission inventory (EI) from on-road vehicular sources were based on the application of IVE methodology, which was developed by the ISSRC (International Sustainable System Research Center). However, the pollutants estimated by this methodology do not include the fraction of PM2.5 and the amount of BC emitted by vehicles. Hence, the aim of this study was to evaluate different methods and information from literature in order to determine PM2.5 and BC emissions from on-road vehicular sources in the emissions inventory year base 2017.

 

The results obtained were analyzed considering studies published by the EPA, and other literature reported mainly in the United States, Mexico, and Canada. The results suggest that the ratio between PM2.5 and BC vary considerably according to vehicular type (mainly trucks and buses) with 56% and 59% respectively.
