“…There was a similar pattern in seasonal variation at sites 2, 3, 4, and 5, with higher values in February, March, and April. Similar results were also reported in the Xi'an and Guangzhou areas (Huang et al 2014), where the deposition fluxes was at their maxima in spring, most likely a result of fuel combustion and vehicle emissions (Klumpp et al 2003;Loppi et al 2004). Generally, the prevailing wind in the spring in Shanghai was from the south or southeast of China, where there were larger emissions of dust from the increased consumption of coal in industrial production ( Fig.…”

The bulk deposition of both PAHs and metals is a significant, mounting issue for the urban ecological environment. However, studies generally performed on these pollutants have focused on the regions surrounding a pollution source; thus, it most likely overestimated pollutants in the cities. Therefore, 72 atmospheric bulk deposition samples were collected from six sites located along a transect from the suburbs to the city center in Shanghai over a 1-year period (February 1, 2012 to January 31, 2013). The seasonal variation, spatial distribution, and sources of multiple metals (Al, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, As, Cd, Pb, K, Na, and Mg) and 16 polycyclic aromatic hydrocarbon (PAH) compounds were determined. The results indicated that the annual average rate of dust deposition in Shanghai was 43,100 ± 54,800 mg/ m 2 /year. There were significant or high enrichments of Cu, Zn, Cd, and Pb, and higher depositional fluxes were observed for Zn, Pb, and Cd in the Huangpu district and for Cu in the Minhang district. The deposition fluxes of the PAHs exhibited the following order: urban fringe zone > city center > rural zone (background site). However, unlike in northern Chinese cities, the high-molecular-weight PAHs accounted for most of the PAHs. Furthermore, there were higher depositional fluxes of PAHs in March, July, and October. Overall, the factors influencing urban air quality may include construction, fossil fuel combustion, the abrasion of tires and brake linings (directly related to traffic), the corrosion of galvanized protection barriers, and increasing population density.

“…Similarly, As was assumed to be exclusively in its inorganic form for risk assessment. The assumptions for As and for Cr have been supported by results from recent studies (Brown et al, 2014;Huang et al, 2014).…”

“…The increase in the number of sandstorms is due to the intensification of desertification, which in turn is encouraged by sandstorm events exacerbating drought conditions in semiarid areas. The dust is mainly composed of iron oxide minerals (such as hematite and goethite), carbonate minerals (such as calcite and dolomite), and quartz and clay minerals (such as kaolinite, illite, and montmorillonite) [3][4][5]. A broad variety of chemical species, both organic and inorganic, have been discovered in atmospheric deposition [6].…”

“…Crucial factors determining the deposition rate include the chemical characteristics of the depositional environment, types and distance of emission sources, and some meteorological conditions [20,21]. In particular, information regarding the spatiotemporal variability of the dust rate provides a powerful framework for evaluating deposition characteristics in a given location [19,21,22].Dust transmission plays an important role in Earth's systems [1][2][3][4][5][6]. Aeolian sand is a major driving force in the climate system through its influence on light scattering/absorption, cloud properties and the ice and snow albedo [23][24][25][26][27].…”

A New Geochemical Method for Determining the Sources of Atmospheric Particles: A Case Study from Gannan, Northeast China

The geochemical characteristics of atmospheric deposition can help trace the origin and assess the impacts of pollutants. Northeast China has always been a region seriously affected by sandstorms. This study aims to explain the potential source of sandstorms in Gannan County, Heilongjiang Provence, by collecting dust and analyzing geochemistry in one year where there is no significant industrial or anthropogenic pollution. Input fluxes of deposition show that Zn and Mn were more prevalent (36.7 g·hm−2·a−1 and 77.93 g·hm−2·a−1, respectively) than other elements. The geochemical composition of atmospheric deposition samples from 17 collection points in Gannan County were determined with regard to 20 elements including nine heavy metals, two metalloids, three nonmetallic elements, a transition metal, and five other major elements. The discriminate function (DF) and chemical index of alteration (CIA) indices indicate that Gannan County (agricultural production area) and Harbin (densely inhabited district) have similar geochemical characteristics of dry deposition. The integration of Na/Al and Ca/Mg ratios with an air mass back-trajectories model shows effects from Russian dust sources (36.6%) and from the northwest desert of China (13.3%). The results will assist in developing strategies for reducing dry deposition pollution inputs to agricultural soils in the area and will effectively target policies to protect soils from long-term contaminant accumulation.
