Estudio de SO2 y NO2 empleando muestreo pasivo en la zona industrial de vía la costa - Guayaquil.

Abstract

The high traffic existing abundance in Guayaquil and the accession of industries that by means of his productive processes they generate combustion permit to develop the study of SO2 and NO2 in the industrial park of route to the coast during the period November 2016- January 2017 using the methodology of samplers liabilities that it consists of placing solutions catchers specific for SO2 and NO2 of tetracloromercurato of sodium and trietanolamina respectively in glass pipes placed to 2.5m of height in 20.0 selected points a randomly from gardens of the salty one up to the km 26.0. The analyses of the samples allowed to calculate the concentration existing of the pollutant gases obtaining thus maximun values in points 13 and 14 for him NO2 equally to 64,346 µg/m³ and 75,649 µg/m³ of equal way of for SO2 in the points 10 and 11 register values of 30,389 µg/m3 and 36,013 µg/m3 that do not exceed the limit allowed by the Ecuadorian norm for the dioxide of equal nitrogen to 200 µg/m³ in an hour and for the dioxide of equal sulphur to 125 µg/m³ per day according to the ministerial agreement 097A book VI attached 4 quality of the air proved formed of maps that from the colorimetric scale show the variation of concentration in the area of study . The analisys of give you it allowed to conclude not existence of correlation between the meteorological parameters granted by the national institute of meteorology and hydrological (INAMHI) and the concentration obtained of the passive captors therefore they do not influence the pre-valency of the pollutant gases the zone which dispersion is not significant and the prevalency n the al mostconstant time therefore the obtained concentrations do not exceed the allowed limit. It is necessary to develop a study of specific sources (hinges or mobiles) of emission of dioxides of nitrogen and sulphur that it authorizes to determinate the direct relation between the concentration and the source of generation of air pollution.
