PRENDEZ, Margarita; CORVALAN, Roberto M  y  CISTERNAS, Michael. Preliminary Study of Particulate Matter from Stationary Sources: Application to an Emission Compensation System at the Metropolitan Region, Chile. Inf. tecnol. [online]. 2007, vol.18, n.2, pp. 93-103. ISSN 0718-0764.

The strategies contained in the Atmospheric Prevention and Decontamination Plan for the Metropolitan Region of Santiago, Chile, include a pollutant emission compensation system involving all new stationary sources initiating operations in the region as well as all existing sources and expansions. The emission compensation system is currently applied on the basis of total mass emissions. Under the hypothesis that damage to health from particulate matter exposure depends strongly on particulate size and chemical elements, a physical-chemical characterisation study of emissions from different types of stationary sources in Santiago was carried out for the purpose of determining the appropriateness of this environmental management tool. Results showed notable differences in elemental composition from different source types, leading to the conclusion that the application of the current emission compensation system is not appropriate for improving the quality of the air in the city.
