Assessment of Windbreaks as a Dust Control Strategy for Communities in Arid Climates Such as the Us-mexico Border Region
NARRATIVE SUMMARY Dust generated from the mechanical disturbance of granular material is known as " fugitive dust " since it is not released into the atmosphere in a restricted flow stream such as an exhaust pipe or smoke stack. Fugitive dust includes dust from unpaved roads, disturbed land in developed areas, agriculture, and undeveloped grazing land. Wind-blown and vehicle generated fugitive ...
متن کاملPreliminary assessment of an economical fugitive road dust sampler for the collection of bulk samples for geochemical analysis.
Fugitive road dust collection for chemical analysis and interpretation has been limited by the quantity and representativeness of samples. Traditional methods of fugitive dust collection generally focus on point-collections that limit data interpretation to a small area or require the investigator to make gross assumptions about the origin of the sample collected. These collection methods often...
متن کاملFugitive Dust Generation in the Laboratory
Fugitive dust (dust composed of natural materials, suspended into the air by human activities) is an air quality concern in many agricultural regions of the United States. Fugitive dust is generated almost everywhere by vehicles traveling on unpaved or sediment-covered roads and at construction and waste management sites (Cowherd et al., 1988). In the Southern High Plains of Texas and the Colum...
متن کاملCharacteristics of Fugitive Dust Generated from Unpaved Mine Haulage Roads
Fugitive dust is generated along unpaved mine roads from intermitlent equipment traffic. Typically. the majority of such traffic consists of trucks hauling either mine product or waste from the surface mine pit andlor the processing plant. Fugitive dust generated along these unpaved mine roads includes particles of all sizes which become airborne. The potential hazards include the deleterious e...
متن کاملNumerical validation of a near-field fugitive dust model for vehicles moving on unpaved surfaces
This paper presents a numerical model for evaluating fugitive dust emission and transport at near-field induced by a moving vehicle. The dust emission model describes the quantity and location of emitted dust. The transport of the dust is captured by the Lagrangian particle tracking method, and turbulence dispersion of particles is modeled stochastically. The presented model is validated ∗corre...
