MARTINEZ-ANGEL, Juan D.. Motorized mobility, environmental impact, alternatives and future prospects: considerations for the Área Metropolitana del Valle de Aburrá. Rev. salud pública [online]. 2018, vol.20, n.1, pp.126-131. ISSN 0124-0064.  https://doi.org/10.15446/rsap.v20n1.57038.

Motorized mobility is closely linked to liquid fuels such as gasoline and diésel and therefore, to the environment. Besides the problems associated with global warming, the use of these fuels also generates polluting compounds affecting the population health. Among all primary pollutants, particulate matter (PM) less than or equal to 2.5 microns (PM25) in size, is regarded as one of the most dangerous compounds because it can penetrate the region lung gas exchange. The records for the Área Metropolitana del Valle de Aburrá (AMVA) often show that the average levels of air quality were found to be harmful to the health of metropolitan habitants. This is mainly attributed to the high concentrations of PM25 generated by heavy-duty vehicles that use diésel fuel. Although the properties of diesel fuel have a direct effect on breathable PM, there are other strategies influencing both nature and amount of emissions. For example, the improvement of the technological level of the engines and the driving pattern, as well as the incorporation of electric vehicles. This paper shows some considerations in order to propose possible strategies to solve the environmental problem of the city and the country.
