“…These urban ammonium levels are similar to or somewhat higher than those from Hanoi, Vietnam (Celis et al 2004;Chow et al 1993Chow et al , 2002Kim et al 2000). All of these suggest that Beijing still had a considerable amount of ammonium product even during the Olympic period when control measures were implemented.…”

“…PM also have a pronounced effect on atmospheric chemistry and air quality including cloud formation, visibility, solar radiation and acid deposition (Khoder, 2002;Watson, 2002;Celis et al, 2004;Tsai and Chen, 2006). Total suspended particulates (TSP) and PM with the aerodynamics diameter less than 10 μm (PM 10 ) were considered as the potential reason of heavy air pollution in China, especially in northern China.…”

Ambient particulate matter with the aerodynamics diameter less than 10 μm (PM 10 ) was sampled in four northeastern Chinese cities (Shenyang, Anshan, Fushun and Huludao) , organic and total carbon were determined. In addition, chemical source profiles consisting of the same particulate components were obtained from a number of naturally occurring geological sources (soil dust from exposed lands and marine salt) and sources of atmospheric particulates resulting from human activities (construction derived dust, coal combustion fly ash, iron and steel manufacturing dust, zinc dust, vehicle exhaust, and sulfate). Chemical mass balance modeling (CMB) was applied to determine the particulate matter (PM) sources and their contributions to PM 10 in these four cities. The results showed that soil dust and coal fly ash were the major sources of ambient PM 10 in all four cities. The construction derived dust, iron and steel manufacturing dust also was the major source of PM 10 in Huludao, Anshan, respectively. Higher contribution of iron and steel manufacturing dust (33.3 μg/m 3 , 20.9%) in Anshan was observed in this study, compared with previous studies. The zinc dust was a special PM source of Huludao, with a contribution of 19.1 μg/m 3 (7.0%) to PM 10 .

“…Mass closure analysis has been widely accepted for analysis of aerosols (Kim et al, 2001;Chow et al, 2002; Celis et al, 2004;Duan et al, 2006;Sillanpää et al, 2006;Viana et al, 2006;Koulouri et al, 2008;Terzi et al, 2010), allowing for source reconciliation, quality assurance, health and welfare impacts (Ho et al, 2006). The relative contributions reflected differences in emission sources and processes controlling the aerosol composition (Sillanpää et al, 2006).…”

“…Chemical compositions of particulate matter play an important role in these responses (Lee and Kang, 2001). To test whether the gravimetrically determined mass can be reconstructed by the chemically determined constituents, a mass closure model has been adopted (Celis et al, 2004;Oanh et al, 2006;Viana et al, 2006Viana et al, , 2007Terzi conducted mainly in coastal sites (Terzi et al, 2010;Viana et al, 2006Viana et al, , 2007 considering the influences of both continental and oceanic sources or of a regional megalopolis (Oanh et al, 2006;Celis et al, 2004;Putaud et al, 2004;Ho et al, 2006) in view of the tremendous pressure on atmospheric environments owing to huge population density and heavy traffic. Tsai and Cheng (2004) reported that energy intensive activities connected with industrial processes and other anthropogenic activities were the dominant contributors to PM 10 components.…”

Concentrations of atmospheric PM 10 and chemical components (including twenty-one elements, nine ions, organic carbon (OC) and elemental carbon (EC)) were measured at five sites in a heavily industrial region of Shenzhen, China in 2005. Results showed that PM 10 concentrations exhibited the highest values at 264 μg/m 3 at the site near a harbor with the influence of harbor activities. Sulfur exhibited the highest concentrations (from 2419 to 3995 ng/m 3 ) of all the studied elements, which may be related to the influence of coal used as fuel in this area for industrial plants. This was verified by the high mass percentages of SO 2− 4 , which accounted for 34.3%-39.7% of the total ions. NO − 3 /SO 2− 4 ratios varied from 0.64-0.71, which implies coal combustion was predominant compared with vehicle emission. The anion/cation ratios range was close to 0.95, indicating anion deficiency in this region. The harbor site showed the highest OC and EC concentrations, with the influence of emission from vessels. Secondary organic carbon accounted for about 22.6%-38.7% of OC, with the highest percentage occurring at the site adjacent to a coal-fired power plant and wood plant. The mass closure model performed well in this heavily industrial region, with significant correlation obtained between chemically determined and gravimetrically measured PM 10 mass. The main constituents of PM 10 were found to be organic materials (30.9%-69.5%), followed by secondary inorganic aerosol (7.9%-25.0%), crustal materials (6.7%-13.8%), elemental carbon (3.5%-10.8%), sea salt (2.4%-6.2%) and trace elements (2.0%-4.9%) in this heavily industrialized region. Principal component analysis indicated that the main sources for particulate matter in this industrial region were crustal materials and coal/wood combustion, oil combustion, secondary aerosols, industrial processes and vehicle emission.
