Movilidad motorizada, impacto ambiental, alternativas y perspectivas futuras: consideraciones para el Área Metropolitana del Valle de Aburrá

Abstract

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.

Atrial proarrhythmic effect of lead as one of the PM10 metal components of air pollution. An in-silico study

“…Factories and vehicles arise as big contributors of PM within the city, a previous study reveals that during 2015, factories emitted 56 kg of Pb and 144.9 tons of PM 10 [ 39 ]. In addition, an important part of the vehicles in the city exhibit a significant engine technological backwardness, which favors the emission of PM [ 40 ]. The Pb has been shown as the most dangerous heavy metal, able to cause harmful effects in human beings [ 41 ].…”

La ética del control de la contaminación ambiental automotriz en el Ecuador

“…Los efectos negativos de la industrialización no tuvieron un enfoque en sus comienzos no siendo así a partir de los ochenta donde se comenzó a realizar conciencia desde la parte de los gobiernos dando así la pauta para la implementación de medidas que permitieran la prevención de la contaminación donde se logre un equilibrio entre los procesos de la industria desde la mano humana y el medio ambiente. Este factor medioambiental se convirtió en un aspecto fundamental de manera decisiva y a la vez una ventaja hacia la competencia (Martínez, 2018).…”
