MAZZEO, N.A.; PINEDA ROJAS, A.L.  and  VENEGAS, L.E.. Carbon monoxide emitted from the city of Buenos Aires and transported to neighbouring districts. Lat. Am. appl. res. [online]. 2010, vol.40, n.3, pp. 267-273. ISSN 0327-0793.

Air pollutants emitted in a city may reach neighbouring areas. This paper describes and applies a methodology for estimating the CO transported from the City of Buenos Aires (CBA) to neighbouring districts. The methodology is applicable only for inert pollutants. This preliminary evaluation shows that 32% of CO annually emitted is transported to the de la Plata River. The smallest fraction (7.5% of annual emission) goes to the district of Avellaneda. The main factors controlling the outflow flux of CO are evaluated and their relative importance is discussed. It is also evaluated that the CO emissions in the CBA may contribute to 8h-CO background concentrations in the Metropolitan Area of Buenos Aires (MABA) with more than 10% of the Air Quality Standard. The districts of the MABA located west and northwest the CBA are the more affected by the CO emitted in the CBA.
