Determinación de las emisiones de partículas en suspensión (PM10 y PM2.5 ) por movimiento eólico mediante simulación matemática en la provincia de Chimborazo del año 2015.

Abstract

The particulate matter analysis (PM10 and PM2.5 ) product of the wind power was carried out in 2015 at the Chimborazo province, using mathematical modeling established by the WRAP report, including mathematical formulae and their numerical conditions, in additions the use of wind speed meteorological data taken during the 2015 year in a sequence of 3 times a day. Using the ArcGis software, the emission mesh was obtained with an extension of 1 km xiv 2 for each cell and by the Spline tool that allows interpolating and linking wind speed data, the cover vegetation and land use map of 2014 year. Also values of the friction surface were determined for different soil types, obtaining the PM10 values and determining 15% as result for PM2.5, The type of soil wiyh longer length was grassland producing higher re-suspension of PM with a total of 17450, 164 g/m 2 a month. The result of total PM10 emissions in re-suspension for 2015 year was 29236,245 g/m 2 a month, of which 59,76% were issued in august caused by the strong winds that start at early hours of the day, the low cloudiness and for being the dries season in Ecuador. Consequently Alausí and Guamote were the most affected with 94,299 g/m 2 a month; in august and the least affected canton was Guano that in most of months except June did not get PM emissions. It is concluded, that this research method gives us a focus on improving the quantity of breathing air, due to the serious effects on human health and the environment that the particulate matter causes, needing strategies for pollution and providing power for atmospheric compounds being able to infer transport and chemical transformation.
