    Validación del método para la determinación de material particulado PM-10 y PM-2,5 en aire ambiente
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos. Carrera de Ingeniería Bioquímica, 2019-01) Tituaña Quillupangui, Carlos Andrés; Pérez Aldas, Lánder Vinicio
    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.

    Análisis cuantitativo del material particulado sedimentable con variables metereológicas en 13 estaciones de la ciudad de Ambato
    (Universidad Técnica de Ambato. Facultad de Ciencia e Ingeniería en Alimentos. Carrera de Ingeniería Bioquímica, 2016-10) Bermeo Acurio, Adrián Vinicio; Sánchez Almeida, Miguel Andrés
    The current research consists in an evaluation on the environmental pollution caused by the Sedimentable Particulated Material (SPM) in Ambato city, that was elaborated in order to establish measure that decrease their concentrations. It was done out from January to June 2016 with a monitoring liability wherein 13 points located in: Luis A. Martínez, Techo Propio, Bomberos Ingahurco, ESFORSE, Mercado Modelo, Izamba,San Alfonso, Huachi Chico, DTTM, Huachi La Magdalena, Santa Rosa, family park and Judicial Council. The method used was Bergerhoff, dealt pitchers of 15 cm diameter, vessels of precipitation, stir rod, heating, stove, dryer sheet and a balance with which the gravimetric study was conducted and the number of SPM was calculated for 30 days. The experimental design was block design with Statgraphics software to find the analysis of variance (ANOVA) and Tukey. The statistical results showed that there is a significant difference in the concentrations at all sampling points, the highest value is recorded in the field of Huachi guy with an average of 1.50 mg/cm² * 30 d in every month. The stations that are governed within the who and TULSMA rules are: ESFORSE (0.413 mg/cm² * 30 d), fire Ingahurco (0.425 mg/cm² * 30 d) and Luis. Martinez (0.458 mg/cm² * 30 d). In conclusion that there are high values of SPM in several areas of the city, which can influence in the people health.
