    (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. Keywords: coffee;biomaterial;biodegradability

    POTENCIAL IMPACTO AMBIENTAL EN LA SALUD POR CONTAMINANTES ATMOSFÉRICOS MEDIANTE EL SOFTWARE AIRQ+ EN LA PAZ Y EL ALTO, BOLIVIA.
    (2023) Garvizu Auza; Bustillos Cárdenas; Revollo Sprella; Mendoza Bruzzone; Soria Cespedes
    Air pollution generates around seven million deaths annually throughout the world according to data from the World Health Organization. The research evaluates the impact of suspended particulate matter with a diameter of less than 10 microns (PM10) in La Paz and El Alto, Bolivia, and its relationship with non-viral respiratory diseases, through on-site information, historical epidemiological data between 2009 and 2019. and the free software AirQ+. It was determined that 35.45% of cases of non-viral respiratory diseases could be attributed to PM10 in La Paz; For El Alto, data from 2016 suggest a relationship with the incidence of chronic bronchitis in adults at 41.53%, a relationship with postneonatal infant mortality at 17.32%, and a prevalence of bronchitis in children of 31.15%. For La Paz, a simulated scenario where the concentration remains below the permissible limits, suggests a reduction in the prevalence of non-viral diseases attributable to PM10 of 2.75% in post-neonatal infant mortality, 4.83% in causes of bronchitis in children under five years of age and 16.2% in chronic bronchitis in adults; For El Alto, a similar impact is expected considering that the permissible limit values ​​were exceeded by 30%. Keywords: suspended particulate matter with a diameter of less than 10 microns (PM10); respiratory diseases; mathematical modeling
