“…Table 2 compares our results with previous measurements of the metals in PM 2.5 samples collected from various sites, including rural, urban, industrial, forest, suburban, mountain, and island sites cities in China, Europe and United States [28,31,33,59,60]. Overall, the concentrations of dust-related metal elements in suburban Nanjing were at similar levels compared with those from some rural sites in foreign countries like Switzerland, Los Angles, USA, but with higher concentrations of some heavy metals derived from vehicle and industrial emissions, although levels of these metals appear to be lower than those in a few cities, such as Xi'an, Ji'nan and Zhuzhou [33]. In details, concentrations of Na, Mg, Al measured in this study were much lower than those found at the rural sites of China, while generally higher than the reported concentrations in other countries such as Switzerland [46] and Los Angles, USA [23].…”

Abstract:In this work, the seasonal variations and sources of trace metal elements in atmospheric fine aerosols (PM 2.5 ) were investigated for a year-long field campaign from July 2012 to June 2013, conducted in suburban Nanjing, eastern China, at a site adjacent to an industry zone. The PM 2.5 samples collected across four seasons were analyzed for 17 metal elements, namely, Sodium (Na), Magnesium (Mg), Aluminum (Al), Vanadium (V), Chromium (Cr), Manganese (Mn), Nickel (Ni), Copper (Cu), Zinc (Zn), Arsenic (As), Selenium (Se), Strontium (Sr), Cadmium (Cd), Barium (Ba), Lead (Pb), Molybdenum (Mo), and Antimony (Sb) using an inductively coupled plasma mass spectrometry (ICP-MS). We found that the total concentration of all 17 metal elements was 1.23 µg/m 3 , on average accounting for 1.0% of the total PM 2.5 mass. For our data, mass concentrations of Al, Cd, Ba were highest in summer, Mg, Cu, Zn, Se, Pb peaked in autumn, Cr, Mn, Ni, As, Sr, Sb increased significantly in winter, while the concentrations of Na, V, Mo were at their highest levels in spring. Air mass back trajectory analysis suggested that air parcels that arrived at the site originated from four dominant regions (Japan, yellow sea and bohai; Southeast of China, the Pacific Ocean; Southwest of Jiangsu and Anhui province; Northern Asia inland and Mongolia region), in particular, the one from Northern Asia inland and Mongolia contained the highest concentrations of As, Sb, Sr, and was predominant in winter. Positive matrix factorization (PMF) analyses revealed that the industrial emission is the largest contributor (34%) of the observed metal elements, followed by traffic (25%), soil dust (19%), coal combustion (10%), incineration of electronic waste (9%), and a minor unknown source (3%). In addition, we have also investigated the morphology and composition of particles by using the scanning electron microscopy (SEM)/energy-dispersive spectrometry (EDS) techniques, and identified particles from coal burning sources, etc., similar to the PMF results.

“…The grain size distribution of dust is particularly important because it determines the mobility and sources of the particles [24, 25]. To illustrate the characteristics of foliar and road dust particle size from Panzhihua City, the particles were placed in classes according to the following fractions: ≤2.5μm (clay), 2.5–10μm (silt), 10–20μm (silt), 20–63μm (silt), 63–125μm (very fine sand), 125–250μm (find sand), and 250–500 μm (medium sand) as shown in Figs 2 and 3.…”

“…The results show there were two under-developed tile kilns in this area between S05 and S06. The ash was discharged without any treatment and returned to ground surface through atmospheric deposition, and waste residue was banked up in the field, which had high contents of Cr, Fe, Ni, Pb, V, Zn, and so on [15, 24]. In addition, the AA was at the downwind direction of IA, the atmospheric dusts from the latter might influence the former.…”

Tracing Sources and Contamination Assessments of Heavy Metals in Road and Foliar Dusts in a Typical Mining City, China

et al. 2016

Road and foliar dust samples from four land-use districts of Panzhihua City, a famous V-Ti magnetite production area of China, were collected to investigate the sources and distribution characteristics of 9 heavy metals (V, Pb, Cd, Cu, Zn, Ni, Cr, Fe, and Mn). The results suggest that foliar samples had smaller particle size and higher heavy metal contents than road dusts. The contamination assessments of heavy metals were as follows: Pb and V (significant enrichment) > Zn, Ni, Cr, Fe, and Mn (moderate enrichment) > Cd and Ni (minimal enrichment). Statistical analyses showed Pb, as the primary pollution element, originated from waste incineration and lead-fuel combustion. The sources of Zn, Ni, Cr, Fe, V, and Mn were fugitive dust and traffic activities. Potential origins of Cu were corrosion of alloys used in vehicle components, vehicle covers, or other metallic surfaces and materials. The sources of Cd were different from any other heavy metals. Traffic and industrial activities were the main anthropogenic origins of heavy metals in dusts of Panzhihua, and more attention should be paid to heavy metal pollution in agricultural area.

“…The relative importance of the sources of airborne trace elements has already been discussed, especially at urban cities and industrial regions (Lee et al, 2007;Nazir et al, 2011;Pui et al, 2014;Saffari et al, 2013). It has been well documented that trace elements like nickel (Ni), chromium (Cr), vanadium (V), zinc (Zn), cobalt (Co) can be emitted from sources of industrial and fossil fuel combustion Li et al, 2013); manganese (Mn), lead (Pb), barium (Ba), copper (Cu), zinc (Zn) are the tracers of traffic emissions (Bukowiecki et al, 2009;Zhang et al, 2009); Arsenic (As), strontium (Sr), selenium (Se) are produced from coal combustion (Makkonen et al, 2010); Aluminum (Al) and magnesium are identified as the tracers of soil or dust (Pavuluri et al, 2013). In recent years, the advanced positive matrix factorization (PMF) method has been applied to assess trace elements' sources in a few developed countries (Qin et al, 2006;Rizzo and Scheff, 2007;Yang et al, 2013).…”
