The objective of this study was to identify the presence of pathogenic microorganisms in water supply systems for consumption in human settlements in the city of Pucallpa, Ucayali region. For data collection, the "Protocol of procedures for sampling, preservation, conservation, transport, storage and reception of water samples for human consumption" was used, within the framework of the Quality Management System -NTP ISO/ IEC 17025. Samples from 12 water supply systems were analyzed, with 3 replications per water system. As a result, fecal coliform bacteria were identified in 66% of the systems in ranges from 2 CFU/100 ml to 31 CFU/100 ml, Thermo-tolerant coliforms in 25% of the systems in ranges from 2 CFU/100 ml to 5 CFU. /100 ml, E.coli in 25% of the systems in ranges from 1 CFU/100 ml to 2 CFU/100 ml, Salmonella spp. in 8.3% of the systems in ranges of 1 CFU/100 ml. However, the presence of Legionella spp., Pseudomonas aureginosa and Vibrio Cholerae was not identified in the systems. In 100% of the systems, the presence of Protozoa and Helminths was not identified. It is concluded that 66.6% of the water supply systems evaluated, present pathogenic microorganisms in the water destined for the consumption and use of the population to serve human settlements, therefore, they do not comply with the Maximum Permissible Limits established in the DS.031-2010-DIGESA "Regulation of the quality of water for human consumption".
Las mascarillas durante muchos años fueron utilizados como medio de protección, para profesionales de salud, sin embargo durante la pandemia la población mundial se vio obligada a utilizarla como medio de protección algunos dándole un uso inadecuado que conllevo su cauto infección o contaminación por otros microorganismos, es por eso que en el presente libro comprende una investigación que buscó determinar los microorganismos presentes en las mascarillas de los pobladores de Pucallpa (Perú) para la protección de la COVID – 19, para ello se recolecto mascarillas quirúrgicas, KN95 y tela, utilizadas por los pobladores de los distritos de Campoverde, Yarinacocha, Manantay y Callería, obteniendo 15 mascarillas por distrito. La identificación de micoorganismos se realizó a través de pruebas bioquímicas (método tradicional) y automatizado (Vitex). Se aisló 12 especies de bacterias En el caso de hongos se encontró dos familias Trichocomaceae (Aspergillus spp) y Saccharomycetaceae (Candida famata y Candida parapsiliosis). No fue posible encontrar el virus del COVID-19 en las mascarillas, puesto que no se evidencio presencia del Gen N, Gen ORF1ab. El mayor número de especies de bacterias corresponde a la familia Enterobacteriaceae, registrado en el distrito de Campoverde y Yarinacocha, mientras el hongo que más se encontró fue Aspergillus spp registrado en los cuatro distritos.
The objective of this study was to evaluate the Carbon Monoxide Levels caused by the “San Juan” festival in the city of Pucallpa 2021. The methodology used was through the use of electrochemical sensors, taking 2 schedules specific diurnal (7 am to 2 pm) and night (6 pm to 1 am) in ranges per sampling point with analysis intervals of 5 seconds to obtain the average. Twelve randomly distributed points in the city of Pucallpa were analyzed, evaluated for 9 days. The results indicate that 8 out of 10 families used firewood or charcoal to cook the Juane and that 9 out of 10 families made or cooked the juane for the festival of “San Juan- Pucallpa 2021” on June 23 (one day before the festival). Likewise, the levels of Carbon Monoxide before the festival of “San Juan” were an average of 4,270 mg / m3, during an average 6,660 mg / m3 and then an average of 4,940 mg / m3 in the city of Pucallpa in the year 2021. It is concluded that the effect on the levels of Carbon Monoxide caused by the festival of "San Juan" in the city of Pucallpa in 2021, is that the National Air Quality Indices were "Good" before and after the festival, but classified as “Moderate” during this.
