Los objetivos del proyecto consistieron en demostrar la utilidad de una técnica simple que involucra aparatos rotativos pequeños y cintas adhesivas para colectar material particulado (MP) suspendido en el aire que es emitido por el tráfico vehicular, así como llevar a cabo la cuantificación de la masa y comparar los datos de las cintas adhesivas con los datos del muestreador MET-1. Las muestras de MP fueron colectadas mediante aparatos rotativos con cintas adhesivas a 1.5, 4.5 y 6 m de altura con base en la superficie del terreno a los lados Este y Oeste de dos caminos agrícolas en el Valle de Juárez, Chihuahua, México. El análisis del suelo de los caminos evaluados mostró que el contenido total de limo y arcilla en promedio fue de 51±0.7% y el contenido de humedad gravimétrico in situ fue de 3.47±0.3% en el sitio del rancho universitario de la Universidad Autónoma de Ciudad Juárez (UACJ), mientras que en el sitio Rodela fueron de 52±3.3% y de 2.13±0.17%. La cantidad de MP retenido en las cintas adhesivas se incrementó desde 4.02 mg m-3 a 32 km h-1 hasta 16.07 mg m-3 a 64 km h-1. Los factores de emisión estimados para el total de MP suspendidos fueron 3469 g km-1 a 32 km h-1, 3918 g km-1 48 km h-1 y 4271 g km-1 a 64 km h-1, respectivamente. La cantidad de partículas medidas por el muestreador MET-1 a 1.5 m sobre la superficie del terreno se incrementó desde 0.08 mg m-3 a 32 km h-1 hasta 0.14 mg m-3 a 64 km h-1 en el camino Rodela. Las cintas adhesivas aportaron información sobre la cantidad de partículas y demostraron su utilidad para caracterizar el MP dispersado en el aire.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract: Dust emission due to vehicular traffic on unpaved rural roads starts with the pulverization of surface material by the force of the wheels, uplifting and exposing road dust to strong air currents behind the wheels. The objectives of the project were to demonstrate the usefulness of a simple technique involving sticky tapes and rotorod samplers for collecting suspended airborne particulate matter (MP) emitted from unpaved road due to vehicular traffic, to carry out the mass accounting and to compare sticky tape data with MET-1 sampler data. Dust samples were collected 1.5, 4.5 and 6 m above the ground surface on the east and west sides of two roads in Valle de Juarez, Chihuahua, Mexico. The soil analysis showed that average total silt and clay content of road dust was 51±0.7 %, and in situ gravimetric moisture content was 3.47±0.3 % on the "UACJ" road, whereas it was 52±3.3 % and 2.13±0.17% on the "Rodela" road. Concentration of particles retained on sticky tapes increased on average from 4.02 mg m-3 at 32 km h-1 vehicle speed to 16.07 mg m-3 at 64 km h-1 at the "Rodela" site. Emission factors estimated for the total suspended MP were 3469 mg m-3 at 32 km h-1, 3918 g m-3 48 km h-1 and 4271 g m-3 at 64 km h-1 vehicle speed, respectively. The concentrations of particles measured by MET-1 sampler at 1.5 m above soil surface increased from 0.08 mg m-3 at 32 km h-1 to 0.14 mg m-3 at 64 km h-1 vehicle speed at the "Rodela" site. Sticky tapes provided information on the amount of particles, and demonstrated the usefulness of sticky tapes for characterizing airborne MP.]]></p></abstract>
