Fugitive road dust (FRD) particles emitted by traffic-generated turbulence are an important contributor to urban ambient fine particulate matter (PM2.5). Especially in urban areas of developing countries, FRD PM2.5 emissions are a serious environmental threat to air quality and public health. FRD PM2.5 emissions have been neglected or substantially …

Urban fugitive dust is a significant contributor to atmospheric PM2.5 and a potential risk to humans. In 2019, both road dust and construction dust were collected from four cities, including Xi'an, Xianyang, Baoji, and Tongchuan, in Guanzhong Plain, China. Elements, water-soluble ions, and carbonaceous fractions were determined to establish …

The volume of air supply was maintained using a 10.6 m3/min (375 cfm) compressor and the blast cleaning air pressure at the nozzle was held constant between each abrasive at 621 – 690 kPa (90 – 100 psi) as in the Phase 1 report. The target air flow was maintained between 0.25 – 0.36 m/s (50 to 75 fpm).

top of a berm to stabilize the stack. This road is a source of vehicle-generated fugitive dust, and methods were developed to separate out the contribution from the fly ash emissions signal. The results suggest PM2.5 and PMc emission factors for both fly ash and road dust that are considerably lower than those based on AP-42 methods.
