    Evaluación de la calidad del agua - índice de arsénico en la quebrada Rasuyacu en la parroquia Toacaso del cantón Latacunga

    This research constitutes an analysis of the problem of arsenic in the water for agricultural consumption in the Toacaso parish, which is located in the Latacunga canton. The objective of this study is to determine the presence of total arsenic in surface water samples used for consumption in agricultural soils in the Toacaso parish. The evaluation of risks to human health was carried out to estimate the probable risk that is caused by exposure to arsenic through the oral route and the evaluation of the environmental quality of the soils. Arsenic is naturally present at high levels in the groundwater of several countries. Arsenic is highly toxic in its inorganic form. Their greatest threat to public health lies in the use of contaminated water for drinking, preparing food and irrigating food crops. The presence of arsenic in the soil and in the water sources in Toacaso due to natural factors of geological origin associated with the tributaries of the Páramo de los Ilinizas is described. The evaluation of laboratory analyzes and their percentages of arsenic and iron is pertinent and essential, the implementation of a floating islands system (IFA) with the Vetiver species will help us to improve the quality of the water of the reservoirs with difficulties of contamination by heavy metals. already indicated in different irrigation systems that surround the Toacaso parish of the Latacunga canton. To carry out the evaluation of soil contamination and ecological risk, it will be feasible and essential to use indices such as the enrichment factor (FE), the contamination factor (CF) and the Geoaccumulation index (Igeo), the results of the study or the points intervened in the Toacaso parish indicate low to moderate levels of enrichment of (As) and moderate to considerable contamination. Although the level of enrichment in the sediments of the Páramo Ilinizas is severe due to its discharges and tributaries.

    Diagnóstico de la gestión de los residuos y aparatos eléctricos y electrónicos en desuso recolectados por la Municipalidad de Ambato
    (Universidad Técnica de Ambato. Dirección de Posgrado. Maestría en Gestión Ambiental, 2022-07-26) Baño Morocho, Juan Huberto; López Pérez, Jessica Liliana
    This study conducted an evaluation of the management of waste electrical and electronic equipment (WEEE) in disuse collected by the municipality of Ambato, as well as a proposal to improve the management of electrical and electronic waste, including circular economy criteria. For this purpose, the qualitative and quantitative collection and analysis of WEEE management was carried out by applying interviews, observation techniques contrasting with the review of scientific articles, books and journals; likewise, WEEE collection data for the period 2017-2021 was obtained and the evaluation of environmental impacts was developed through the cause and effect methodology. In this way, it was determined that the management of WEEE in disuse collected by the municipality of Ambato clearly showed a deficiency in the collection and management in the different areas of the city of Ambato, which has led these wastes to be managed informally being a reason for the implementation of door-to door collection modalities by informal recyclers. With respect to the WEEE characterization, electronic devices and telecommunication equipment are the most frequently generated in the city of Ambato, and the values obtained have led to a growth in the consumption rates of electrical appliances and in turn the amount of waste in the environment. Likewise, the lack of criteria to promote the circular economy in the management of WEEE was also evidenced. For which it is recommended that the municipality create specific regulations, capacity building processes and improvements in management mechanisms to promote the reduction, repair and recovery of these devices; to promote a more circular and sustainable model in the city of Ambato.

    Análisis comparativo de la incidencia del ruido por tráfico vehicular en instituciones educativas de la ciudad de Esmeraldas
    (Universidad Técnica de Ambato. Dirección de Posgrado. Maestría en Gestión Ambiental, 2022-07-11) Veliz Zambrano, Narcisa Alexandra; Fernández Sánchez, Lineth del Rocío
    In this research thesis, a comparative analysis of noise levels due to vehicular traffic in two educational institutions in the city and province of Esmeraldas was carried out. The investigation begins with the development of the introduction, where the general objective, the specific objectives and the justification that allowed visualizing the problems that exist in the surroundings of the Sagrado Corazón Fiscal Educational Unit and in the Walter Quiñones Sevilla Fiscal Educational Unit were formulated. The study area was established in the surroundings of the institutions, with the fixed distance grid methodology and the nodes of the grids were taken as the monitoring points to fully cover the extension of the field study and noise monitoring. . We proceeded to search for information about noise pollution in existing studies at the cantonal, provincial, regional, national and international levels, in order to collect information regarding the existing problems in the institutions, regulations in force in Ecuador and the methodologies that are the basis of this research thesis. When obtaining the results of the monitoring, the proposal was made for the creation of noise maps according to the study sector, taking into account the methodology for the processing and manipulation of monitored information using the Qgis 3.2 software. Once the noise pollution information was collected, the statistical and cartographic analysis was carried out, to obtain the results on the noise mapping with respect to the permissible levels according to the use of the land, and the population that lives in the sectors. monitored according to the provisions of the Ministerial Agreement 097 A. And finally, the conclusions and recommendations corresponding to the objectives that were proposed in the investigation were drawn up.
