A study of aerosol levels along roadways in Texas was performed by using high-volume air samplers and stacked filter units. Horizontal and vertical concentration profiles were drawn for several elements as well as total suspended particulate (TSP) mattter. In most cases the concentrations were found to decrease with distance from the roadway, reaching near-background levels at the edge of the right of way. Although the TSP by high-volume sampler was usually in the range of 80-150 ..mu..g/m/sup 3/, the contribution of the roadway to the ambient air loading was usually less than 10-20 ..mu..g/m/sup 3/. The analytical results from samples of dust from the roadway surface at each site were useful in determining the source of the aerosols.
