Street sweeping is often proposed as a means of reducing the emissions from paved roads. The objective of this study was to evaluate the effectiveness of street sweeping on ambient particulate matter concentrations and to determine the difference in source contributions to PM{sub 10} concentrations between street sweeping and non-street sweeping periods. Chemically-speciated measurements of PM{sub 10} and PM{sub 2.5} were taken in the commercial section of Reno, Nevada, for a one-month sampling period. The Chemical Mass Balance (CMB) model was applied to these data and an average of approximatley 50 percent of the PM{sub 10} was apportioned to resuspended geological material. During half of the sampling period, streets in the vicinity of the sampling site were completely swept with a regenerative-air vacuum sweeper, while no sweeping was performed during the remainder of the experiment. Ratios of primary geological contributions divided by primary motor vehicle contributions to PM{sub 10} were compared between sweeping and non-sweeping periods using analysis of variance. This ratio of source contributions minimizes the effects of variations in traffic valume and meteorological dispersion. No significant differences in geological contributions to PM{sub 10} were detected as a result of regenerative-air vacuum street sweeping.
