Evaluation of Regenerative-air Vacuum Street Sweeping on Geological Contributions to PM10

摘要: Street sweeping is often proposed as a means of reducing the emissions from paved roads. The objective this study was to evaluate effectiveness street on ambient particulate matter concentrations and determine difference In source contributions PM10 between non-street periods. Chemically-speciated measurements PM2.5 were taken in commercial section Reno, Nevada, for one-month sampling period. Chemical Mass Balance (CMB) model applied these data an average approximately 50 percent apportioned resuspended geological material. During half period, streets vicinity site completely swept with regenerative-air vacuum sweeper, while no performed during remainder experiment. Ratios primary divided by motor vehicle compared non-sweepin...
