• Abstract:
  Airborne particulate concentrations along Texas roadways were monitored at four sites in three cities. The instrumentation used for this study consisted of ten stacked filter units, eight flow controlled high volume air samplers, and four Lundgren impactors. Instruments were placed 150 ft. (45.7 m) upwind and at assorted distances up to 300 ft. (91.4 m) downwind of each roadway. The stacked filter units were spread from 5 to 90 ft. (1.5 to 27.4 m) above ground level. All other instrumentation was set at a five-foot elevation. Sampling times varied from 2 to 12 hours per sample. A total of approximately 40 hours of data were collected at each site in Dallas, San Antonio and El Paso. Traffic and meteorology data were taken by another project. monitoring gaseous pollutants concurrently at the same sites. Total suspended particulates were determined by weighing all hi-vol filters before and after they were used. The TSP loadings on many of the stacked filter units were also determined. All filters were subjected to quantitative elemental analysis using one of two independent energy dispersive spectrometers. Many filters were examined using both systems. The results of the particulate collection project are presented herein. This report and the experimental data on magnetic tape are available from the Texas State Department of Highways and Public Transportation and NTIS.
