Determinación de la calidad de agua de los ríos Santa Ana y Pajonal en la población de Entre Ríos
(2023) Oller Cruz; Óscar Javier; Alvizuri-Tintaya
For this investigation, the population of Entre Rios in southern Bolivia was used as the study area. In recent years, this region has experienced a population growth that has brought with it negative impacts on its water resources. The Santa Ana and Pajonal rivers run through the urban area of Entre Ríos, being exposed to different sources of pollution generated by it. These waters, which are used for consumption and irrigation, require a constant evaluation of their quality to ensure the well-being of rural communities and the local ecosystem. In this work, five sampling points in the study area were monitored for physical and chemical analysis of the samples. High levels of organic contamination that exceed the national regulations were identified, the source of these being a combination of factors linked to poor wastewater management in the area. Based on the results obtained, strategies are proposed to optimize the current water management, considering the health risks to which the rural communities downstream are exposed due to the lack of an adequate water purification systems.

Determinación de poblaciones vulnerables en sectores críticos de la Cuenca del Río Rocha en Bolivia
(2023) Alvizuri-Tintaya; Paola Andrea; Lo-Iacono-Ferreira; Vanesa Gladys
Rivers are ecosystems that are constituted as indicators of environmental quality thanks to the different types of environmental, and socioeconomic services they offer. Due to the constant expansion of cities, the pollution of rivers is becoming increasingly critical, especially in those rivers that cross or are close to urban centers. In developing countries, such as Bolivia, rivers are an accessible and invaluable source of water for use and consumption, so preserving their quality is essential. There are numerous studies of the water quality of the Rocha River carried out by various institutions that verified the increase in contamination in the body of water. However, the vulnerability for populations and ecosystems have not yet been identified for the entire basin. This research compiled and crossed the available information on anthropogenic activities, water quality, and population distribution to expose the impact on water quality and thus identify vulnerable populations in critical sectors of the Rocha River basin. This study is the base for formulating mitigation actions in the identified areas, to reduce the risk to public health and ecosystems.

Elaboración de biomateriales a través del aprovechamiento de residuos de café
(2023) Shirley Vega; Garvizu Auza; Vidfa Carolina; Alvizuri-Tintaya; Paola Andrea
Coffee is one of the most popular drinks worldwide. Although the coffee industry is of great economic importance, it is considered an activity that produces a significant environmental impact. According to studies carried out, organic coffee wastes become a pollutant agent due to the presence of caffeine, polyphenols, and tannins, among the most important. This research proposes a methodology for the elaboration of a biomaterial from the mixture of coffee grounds with natural polymers. The study of the physical characteristics of the material and its biodegradability were developed to analyze its applicability. Results reveal a potential for the use of coffee grounds, being a possible solution to its generation in Bolivia, the fifth most important country in terms of coffee production in South America.
