La exposición e intoxicación por mercurio (Hg), ha sido referenciada en muchas ocasiones y lugares. El uso indiscriminado de precursores químicos en actividades ilícitas como la minería ilegal de oro, que se ha incrementado considerablemente en los últimos años llevado a que esta sea una de las más peligrosas para los ecosistemas y especies presentes en ella. El objetivo de la investigación fue determinar el riesgo ocupacional al mercurio mediante genotoxicidad por exposición en el proceso de quimbalete minero artesanal, Rinconada – Puno. El estudio se realizó en octubre del 2016, siendo 15 trabajadores voluntarios, los cuales cumplieron con los criterios de inclusión por exposición directa al mercurio y periodo de tiempo según vida toxicocinética promedio (4 horas diarias) en fluido para respuesta adversa. El riesgo ocupacional se determinó mediante los niveles de merc...

The study aimed to evaluate the presence of bacteria (total and thermotolerant coliforms) in the treatment of water using Class C Ultraviolet Radiation (UV-C), the research was carried out in the Quality Control Laboratory of the Treatment Plant  of Potable Water of the EPS, EMSA Puno, because current regulations require that total and thermotolerant coliform readings in drinking water should be 0 CFU / 100 ml, with UV-C radiation being an alternative for the decrease in  Chlorine use.  For what was experimented with a dose of 0,00176 W/cm2/s of UV-C radiation with a dominant wavelength of 254 nm, the experimental water samples were subjected to 1, 2, 3, and 4 seconds of exposure to the mentioned radiation.  For the determination of the bacterial presence in water (total and thermotolerant coliforms), the Membrane Filter methodology was chosen, the results obtained fo...
