Determinación de clorofila A como indicador de polución en los embalses de las hidroeléctricas Agoyán y Pisayambo por el método espectrofotométrico UV visible

Abstract

This project was carried out with the aim of evaluating a pollution method, determining the concentration of chlorophyll A, using the UV-visible spectrophotometric method, because this factor directly influences the contamination of the Agoyán and Pisayambo reservoirs, which have not been thoroughly studied to date and due to the industrial waste, that flows into them, are highly harmed. These bodies of water serve as irrigation in the crops of the surrounding communities and feed natural slopes, transporting a high level of contaminants. These will help reduce the environmental impact caused on these hydroelectric plants, for which it is first necessary to identify a method to study chlorophyll A and its impact on the above-mentioned reservoirs. For this, in situ parameters such as Temperature, pH, Secchi disc and pressure, as well as dissolved oxygen, which together with chlorophyll help evaluate the trofic status of these dams were analyzed. This study was conducted in conjunction with graduate students, who determined other variables such as organic matter, nitrates, and phosphates. This was able to identify that there are significant differences in pollution between these hydroelectric plants, as Agoyan has a eutrophic level and Pisayambo a mesotrophic state. Since Agoyan is limited by the textile area of Pelileo, the agricultural area of Patate, the camal of Baños and other pollution factors typical of the place, unlike Pisayambo, whose anthropogenic activities are limited, due to the low accessibility, reducing the aforementioned factors.
