Characteristics of re-suspended road dust and its impact on the atmospheric environment in Beijing

Concentrations, sources and geochemistry of airborne particulate matter at a major European airport

“…Differently from other road sediment procedures 17,18 consisting in collecting samples directly from road pavement by sweeping sediments and either sieving or inducing resuspension in the laboratory and extracting PM 10 through size selective inlets, 19,20 we developed a field resuspension chamber to directly vacuum, at an air flow rate of 25 l min…”

Ecological Risks and Spatial Distributions of Heavy Metals in Beijing Atmospheric Dust

“…Previous studies involving source apportionment of heavy metals in atmospheric particles from the Beijing urban area suggest different major sources of Cd, which may be due to the atmospheric particles being collected from different areas and during different periods [8,10,[12][13]. However, all of these studies indicate that the Cd pollution in atmospheric particles is usually associated with coal-burning, traffic, and industrial emissions.…”

“…In fact, in recent years the heavy metal pollution of atmospheric particles in Beijing has aroused great attention, and a lot of valuable work has been done to investigate their concentrations, pollution levels, sources, temporal variations, controlling measures, and so on [8,[10][11][12][13][14][15]. However, until now few studies have examined the detailed spatial distributions and ecological risks of the heavy metals in atmospheric particles based on highspatial-resolution sampling over the Beijing urban area due to the relatively heavy workload of the traditional filter membrane sampling method.…”

Grain-Size Distribution and Chemical Speciation of Heavy Metals in Chinese Street Dust

“…Zn, Pb, and Cr concentrations affected by traffi c activity were lower than those in Shanghai, Beijing, and Baoji [18,21]. The reason is because the city scale, population density, and traffi c fl ow of Beijing and Shanghai far exceed those of Wuhu.…”

“…Heavy metals from traffi c and industrial emissions were discharged into an urban environment with particulate matter. Cu concentration in urban street dust in Wuhu was close to the level in Shanghai, and far higher than the level in Baoji and Beijing [18,[21][22], which can be explained by the fact that the automobile industry is the leading industry of Wuhu. Cd concentration in Wuhu dust was obviously higher than the level in Shanghai, caused by the high soil background value of Cd in Wuhu.…”
