Resumen:
Use of gasolines has a primordial interest in the ecological area, due
to the emissions generated by combustion engines. In order to maintain a
good air quality, it is neces-sary to control several gasoline quality
parameters. Mexico City is a metropolis with 4421797 vehicles registered
in 2014, therefore air quality problems are constantly present. Mexican
gasoline quality specifications are regulated by Mexican Official
Standard NOM-016-CRE-2016. Benzene, one of the compounds regulated by
NOM-016-CRE-2016, is known to be a carcinogenic agent. Moreover, it is
considered that the presence of benzene in gasoline can affect
population health due to its volatility, which gets it to be in contact
with the atmosphere and consequently with the population. In this work,
the average amount of benzene present in gasoline commercialized in
Mexico City was quantified by ASTM D5769-15. Results showed it was 0.361
% in Magna gasoline, whereas the average amount of benzene present in
imported gasoline was 0.55 %and 1.28 % in the gasoline produced
locally by PEMEX National Refineries System. This value was higher than
imported and commercialized gasoline. In addition, the estimation of
benzene emissions by mobile sources was 354.79 t during 2017.
