Evaluación las emisiones de compuestos orgánicos volátiles no metanogénicos de origen biogénico en la provincia de Tungurahua en el año 2015.

Abstract

The present investigation evaluated the emissions of non-methanogenic volatile organic compounds of biogenic origin in the province of Tungurahua; based on the development of a land use map identifying the species belonging to each category, identifying their respective emissions, according to the database of the emission factors of the volatile compounds belonging to the University of Lancaster, the European Union and the National University of Peru; This information was processed using the Guenther methodology to know the emissions of isoprene, monoterpene and other volatile organic compounds (OCOV), monthly and annual schedules, which was captured in thematic maps for each of the gases under study, database of temperature and solar radiation of meteorological stations within the province for the generation of the mapping required for these variables, these procedures are performed in the software ArcMap 10.1. Graphs of the emissions of gases, allowed to determine their behavior in the time space, besides determining the influence of the aforementioned climatic conditions in the increase and decrease of their annual production; It was determined that isoprene emissions are directly related to changes in temperature, in the case of monoterpenes a part of the temperature has been concluded that solar radiation is a factor to be taken into account when analyzing the behavior of emissions with respect to the OCOV, the lack of information by the species limited the generation of information for the province, but rather to have the idea that the product is secondary to the chemical processes of the plant always present in the atmosphere; this information is used as a tool for local governments in decision making in the environmental area; in addition to recording the basis for future comparative studies to assess the behavior of emissions in relation to climate change and use suffered by the province and the country in general.
