Resumen

En la presente investigación se realizaron estudios frente a las emisiones de black carbol?, material particulado (PM2.5) y ruido dentro de microbús, buseta y buses escolares de las instituciones educativas colegio del Rosario de Santo Domingo y colegio De La Salle; estas mediciones se efectuaron del 17 de octubre al 07 de noviembre del 2019, por medio de equipos ambientales especializados tales como: Aethalometro modelo AE51, Dust Trak modelo 8535 y el Sonómetro Quest. El estudio se basó en la metodología por Behrentz et al (2005). A partir de los resultados de las rutas escolares del colegio del Rosario de Santo Domingo, se analizó que para la jornada de la mañana con las ventanas parcialmente abiertas el microbús, emite una mayor carga contaminante de black carbon y material particulado (PM2.5), a ser comparadas con la buseta y bus, así mismo, el aporte de emisión de presión sonora en el horario de la tarde con ventanas parcialmente abiertas es mayor con respecto a la jornada de la mañana.

Con respecto a los resultados de las rutas escolares del colegio de La Salle se muestra picos máximos de emisión de BC y (PM2,5) que son 55 (µg/m3) y 162 (µg/m3), respectivamente, para la buseta hermética, para la buseta para BC y (PM2,5) son de 311 (µg/m3) y 1.025 (µg/m3), además, el aporte de emisión de presión sonora es mayor en el horario de la tarde con ventanas parcialmente abiertas. Se concluyó, que las condiciones de los microambientes de las rutas escolares que dan sus servicios escolarizados a ambas instituciones educativas no son las óptimas y seguras para los niños y jóvenes que transitan dentro de ellas.

In the present research, studies were carried out against the emissions of black carbon, particulate matter (PM2,5) and noise inside the minibus, bus and school buses of the educational institutions Colegio del Rosario de Santo Domingo and Colegio De La Salle; these measurements were carried out from 17 October to 07 November 2019, through specialized environmental equipment such as: Aethalometer model AE51, Dust Trak model 8535 and the Quest Sonometer. The study was based on the methodology by Behrentz et al (2005). Based on the results of the school routes of the School of the Rosary of Santo Domingo, it was analyzed that for the morning day with the windows partially open, the microbus emits a greater pollutant load of black coal and particulate matter (PM2,5), to be compared with the bus and bus, the contribution of emission of sound pressure in the afternoon with partially open windows is greater with respect to the morning.

With regard to the results of the school routes of the school of La Salle is shown maximum emission peaks of BC and (PM2,5) which are 55 (pg/m3) and 162 (pg/m3), respectively, for the hermetic buset, for the busette for BC and (PM2,5) are 311 (µg/m3) and 1,025 (pg/m3), in addition, the contribution of sound pressure emission is greater in the afternoon hours with partially open windows. It was concluded that the conditions of the microenvironments of the school routes that provide their services to both educational institutions are not optimal and safe for the children and young people that transit within them.
