“…More than half of the particulate mercury existed in the two finest particle ranges, except in October 2003 at both sites, December 2003 at the suburban site, and April 2003 at the urban site only. These results agree well with those reported by Tsai et al (2003) and Allen et al (2001). It can be seen from Fig.…”

Mercury concentrations in size fractions of airborne particulate matter obtained from urban and suburban sites in Beijing in 2003 and 2004 are presented in this paper. The average concentrations of total particulate mercury were 1.1870.82 ng m À3 with a range of 0.18-3.51 ng m À3 at the urban site and 0.6870.62 ng m À3 with a range of 0.13-2.40 ng m À3 at the suburban site. This is much higher than what is found in Europe and Northern America. The results implie that significant anthropogenic sources in Beijing contribute to the concentration of particulate mercury in air and therefore, to the mercury deposition in this region. There are clear seasonal variations in concentration of particulate mercury with highest concentrations in winter at urban and suburban sites. This illustrates the important contribution from coal burning to particulate mercury during the heating season. The mercury concentration in each size fraction of airborne particulates was closely related to its size range. The highest mercury concentration was found in the size fraction less than 1.1 mm with average concentrations of 0.5970.50 and 0.2970.26 ng m À3 at the urban and suburban sites, respectively. The mercury in this size fraction accounts for 45.779.5% and 41.978.2% of the total particulate mercury, respectively. This implies that a large fraction of the particulate mercury in this area can be transported long range before it becomes deposited. Based on the concentrations of size-fractionated particulate mercury in ambient air, the dry deposition fluxes of mercury were estimated to 407 mg m À2 a À1 at the urban site and 270 mg m À2 a À1 at the suburban site. More than 90% of the deposition flux came from particles larger than 1.1 mm despite a substantial fraction of the Hg found in particles less than 1.1 mm.

“…The potential health risk is highly related to the size and composition of particles and their capability to carry toxic compounds (Spurny, 1998;Hinds, 2012). Recently, ultrafine particles (UFPs), i.e., particles with a diameter less than 100 nm, have attracted great attention due to their high deposition fraction, large available surface area, potential to translocate to the circulatory system, the ability to induce inflammation and higher toxicity than larger size particles (Hinds, 1999;Allen et al, 2001;Morawska et al, 2001). Typically, UFPs constitute more than 80% of PM 10 (Morawska et al, 1998).…”

To characterize airborne particles near high-tech industrial parks, this case study used an eight-stage micro-orifice uniform deposit impactor sampler to analyze trace metal patterns in different size groups of airborne particles at the Central Taiwan Science Park (CTSP) in Taichung. To rapidly screen out the potential pollution sources according to the analytical results, a novel model based on expected value theory is proposed. The analytical results show that the ambient air near the CTSP is rich in fine and ultrafine particles and V, As, Ga and Cd have significant increases in ultrafine particles between upwind and downwind areas of CTSP. The proposed source screening tool indicates that CTSP is the major contributor to airborne concentrations of Ga and As in the ambient air near the CTSP, especially in fine and ultrafine particles.

“…So, Ni and V are tracers of fossil fuels burning (Suarez and Ondov 2002;Moffet et al 2008) and the use of tetra-ethyl-lead as a gasoline additive resulted in emission of submicron lead particles (Murphy et al 2007;Moffet et al 2008). Trace elements of anthropogenic origin released into atmosphere in high temperature processes: combustion of fossil fuels, wood, and waste (Allen et al 2001) or metal working (Ondov and Wexler 1998). Elements originating from the same source have the similar size-distribution (Ondov and Wexler 1998).…”

“…Accumulation mode (0.1-1.0 μm) deposit slowly and can therefore be transported over long distances from their sources, having consequent effects in remote regions (Allen et al 2001). Also, the size distributions can provide information about proximity of the sources to the sampling site.…”

“…The resuspended surface dust make a large contribution to the total natural emission, accounting for >50 % of Cr, Mn, and V, and >20 % of Cu, Mo, Ni, Pb, Sb and Zn and, volcanic activities contributing by 20 % of atmospheric Cd, Hg, As, Cr, Cu, Ni, Pb, and Sb (Pacyna 1998;Allen et al 2001). The dominant contribution of the local resuspension to particulate matter levels has been reported by Đorđević et al 2004.…”
