- ÍtemAcceso AbiertoCalidad del aire en tres parques recreacionales del cantón Cuenca, ecuador mediante el uso de bioindicadores liquénicos(Universidad Católica de Cuenca., 2024) Orrala Vasquez, Domenica Daniela; Alvarez Vera, Manuel Salvador; 0106549009; García Calle, Anthony AlxanderThe study assessed the air quality in three recreational parks in Cuenca, Ecuador, using lichen bioindicators in the La Luz, Tarqui-Guzho, and Ictocruz parks. Primary data regarding the physicochemical air quality were collected on-site from the bioindicators, and secondary data were obtained from the Municipal Mobility Company, EMOV-EP. Ictocruz Park has a more extraordinary species richness than Tarqui-Guzho and La Luz. The atmospheric purity index showed that Ictocruz has better air quality than Tarqui-Guzho and La Luz. Significant differences were found in the Air Quality Index (AQI) by pollutant, with PM2.5 AQI being noteworthy. The study confirmed the reliability of the Atmospheric Purity Index for assessing air quality in urban environments, suggesting the effectiveness of lichens as indicators. These results underscore the importance of using bioindicators to monitor air quality continuously and systematically, along with the need for interdisciplinary strategies for effective environmental management in the city.
- ÍtemAcceso AbiertoFitorremediación de suelos contaminados en mecánicas automotrices, utilizando Lolium perenne y Medicago sativa, en laboratorio(Universidad Católica de Cuenca., 2024) Moreno Molina, Jorge Andrés; Martínez Vega, Augusto Polibio; 0106579568; García Calle, Anthony AlxanderOne of the most prevalent environmental issues is soil contamination due to the spillage of harmful elements, such as automotive residual oil, causing negative impacts on soil's properties and productive capacity. Phytoremediation is an efficient alternative that uses the capacity of certain plant species to extract different contaminants. This research project aimed to analyze the remediation capability of two plant species (Lolium perenne and Medicago sativa) in soils contaminated with automotive residual oils using experimental methods. The findings revealed that, although both selected species have a good capacity for contaminant extraction, Lolium perenne proved to be more efficient. In the case of Lolium perenne, treatment with 25 seeds degraded 44% of the contaminant, and treatment with 50 seeds degraded 54%, being the most effective. In contrast, for Medicago sativa, treatment with 25 seeds degraded 23% of the contaminant, which is the least efficient, and treatment with 50 seeds degraded 39%.

- ÍtemAcceso AbiertoEstudio comparativo espacio temporal de las concentraciones de PM10 en la zona urbana del Cantón Cuenca, entre los años 2014 - 2022(Universidad Católica de Cuenca., 2024) Pinos García, Leslie Melissa; Cordero Cueva, Paula Milena; 0104878939This study aimed to determine the concentration of PM10 particulate matter in the urban area of the canton of Cuenca during the period between 2014 and 2022. It focused on performing a spatiotemporal analysis that included identifying pollution levels and comparing them with current legal regulations. The study was divided into three phases: i) data collection from three meteorological stations, ii) multi-temporal analysis of the PM10 pollutant by combining multispectral remote sensing imagery, and iii) analysis and interpretation of the results obtained. During the analysis, it was established that the station in the Municipality of Cuenca (MUN) had the highest concentrations of the pollutant, possibly due to its location in the center of the urban area, where vehicle density is significant. For the years 2014 and 2017, a trend ranging from -0.4 to -0.5 PM10 (ug/m3) was identified, while in the year 2018, an increase in the pollutant was recorded. From 2019 to 2020, a decrease in particulate matter concentrations was verified, reaching a minimum of -2.0 PM10 (ug/m3). This phenomenon could be attributed to measures implemented during the COVID-19 pandemic. However, in 2021, an increase in the pollutant was observed, exceeding 0.5 PM10 (ug/m3), and from this year on, an upward trend in the concentrations of this pollutant was verified.
