NUNEZ CARABALLO, Vladimir et al. Influence on air quality of sulfur dioxide emissions from fixed agricultural sources in Villa Clara. Ctro. Agr. [online]. 2019, vol.46, n.3, pp.86-95. ISSN 2072-2001.

The dioxide of sulfur in 2014 represented the second pollutant of more emission to the atmosphere for the fixed sources in Villa Clara, being the entities fuel oil consumers the responsible maxims. The objectives of this work have been to quantify the polluting load of the dioxide of sulfur emitted by the sources of the MINAG, to determine the percentage that represents these emissions of the total, for municipalities and consumption of fuel, to evaluate the quality of the air and to propose measures of reduction of the emission. The method applied was using direct mensuration with analyzers of gases and factors of emission of AP-42 of the Agency of Environmental Protection of the United States (EPA), the evaluation of the quality of the air was carried out through the moderation of the dispersion of the pollutant with the software ISC-AERMOD Version 3.15 of the EPA. The results show that the polluting load of the dioxide of sulfur was of 68 t, 80 % emitted in the municipality of Santo Domingo and 97 % to burn fuel oil. The quality of the air is acceptable, faulty and dreadful in near different areas to the emission sources. Applying the measures proposals, the energy efficiency can rise and to reduce the consumption of fuel to 3 % (38 t) and the emission in 1.8 t, favoring the costs of the entities and propitiating smaller deterioration of the quality of the air in the affected areas.

Palabras clave : oxide of sulfur; atmospheric contamination; standard of quality of the air.
