Validación del método para la determinación de material particulado PM-10 y PM-2,5 en aire ambiente

Abstract

At present, particulate matter (PM) air pollution is caused by industrial processes; as well as, by the excessive increase of the automotive park, which increased the problem in the health of the people and the quality of the ambient air. Studies have found that the particulate material with the highest index of influence in health conditions are PM-2.5 and PM-10. For the application of measurement methodology is guaranteed by the application of reference methods internationally validated by recognized institutions such as the Environmental Protection Agency of the United States and verified by accredited laboratories according to standards such as 17025. The validation criteria determined values uncertainty required for verification obtaining values for PM-2.5 of 17.01 percent and PM-10 8.55 percent, these being acceptable ranges proposed for the validation of the method, similarly determining the quality air on the campus of the Technical University of Ambato for PM-2.5 was 16.78 ug for each cubic meter and for PM-10 was 63.35 ug for each cubic meter, these being accepted as the guidelines established in the Text results Unified Environmental Legislation, Annex 4 of Book VI, Official Register No. 387 of 2015. The results establish that, at the Technical University of Ambato, its air quality is Good quality and the concentrations of these parameters do not affect the health of people due to the incidence of particulate matter in air.
