Estimación de emisiones atmosféricas de fuentes de área del cantón puerto francisco de orellana para el año 2020

Abstract

In the last two decades, the population and economic growth of the canton of Puerto Francisco of Orellana has been submerged by the oil boom, generating environmental impacts and problems because the industries and the canton's area sources produce atmospheric pollution. For this reason, the gases they emit must be controlled and interpreted quantitatively in the atmospheric emissions inventories. This work aimed to estimate the atmospheric emissions produced by area sources in the canton of Puerto Francisco of Orellana, province of Orellana, in 2020. The methodology implemented for the area sources (agricultural waste burning, LPG use, service stations, mines and quarries, vegetation and wind erosion) was developed using the emission model guides and emission factors of the European Environment Agency, Intergovernmental Panel on Climate Change and the United States Environmental Protection Agency; and through the governmental bodies, basic information was collected for the respective calculations of each pollutant; visits were also made to the sources, which contributed qualitatively to the spatial and temporal disaggregation of these. This information was used to calculate the annual emissions of each of the air pollutants by area source, which were: CO (14.18 tons/year), NOX (33.21 tons/year), SOX (0.3 tons/year), PM10 (181.33 tons/year), PM2.5 (20.38 tons/year), VOC (6708.17 tons/year) and TSP (363.6 tons/year). Additionally, the disaggregations of each source were analysed by determining their daily, weekly, monthly and annual interaction. Thus, concluding that VOCs are the significant emitters of pollution, the study area covers mostly natural forests; also, the disaggregations showed how each pollutant interacted in that year.
