GIRALDO ARISTIZABAL, WILLIAM ALONSO  e  TORO GOMEZ, MARIA VICTORIA. ESTIMATION OF THE EMISSION POLLUTING AGENTS BY MOTORCYCLES IN THE ABURRA VALLEY. Dyna rev.fac.nac.minas [online]. 2008, vol.75, n.156, pp.241-250. ISSN 0012-7353.

The motorcycle is considered a generating movable polluting gas source like the volatile organic compounds and the carbon monoxide that are released to the atmosphere. In Colombia they have registered in the last years a high increase in the use of this type of vehìculos having increased therefore the emissions, which has contributed with the deterioration of the quality of the air of the Valley of Aburrá. In the other hand environmental regulation is recent and has not applied rigorously yet. Consequently and having like reference international Literature and the measurements in slow motion or minimum march, made by the Metropolitan Area, between January and March of 2006, factors of emission for carbon monoxide and hydrocarbons for the estimation of the impact in the city.

Palavras-chave : Idle; carbon monoxide; hydrocarbons; motocycles; particle matter; concentration; polluting agent; emission factor; world-wide cycle of conduction.
