“…While Asian dust storms frequently invade North Taiwan, they seldom arrived in South Taiwan during recent decades (Liu 2002;Wang et al 2002;Lung et al 2004;Hsu et al 2004). Yellow rain episodes were reported in Japan and Taiwan at the end of March 2000 (Sun 2000;Ma et al 2001).…”

“…Previous studies showed that east Taiwan Strait and Japan are also influenced by Asian dust storm to a certain extent, but much weaker than that of Beijing and Qingdao (Hsu et al, 2004(Hsu et al, , 2005Mori et al, 2003). Thus, Fe concentration in Qingdao is less than that in Beijing but higher than that in the other coastal cities (Fig.…”

“…These atmospheric contaminants are apparently influenced by local pollution emissions in summer and by long-range transported dust from the Chinese mainland in spring (Hsu et al, 2005(Hsu et al, , 2006. However, only a few researches were focused on elemental characteristic of oceanic aerosols in Xiamen (e.g., Chen et al, 1999;Hsu et al, 2004Hsu et al, , 2005Hsu et al, , 2006. In the Western Taiwan Strait, the early studies which paid attention on airborne elemental concentrations such as Al, Pb, Cu, Cd, etc., were carried out in 1991-1993 (Chen et al, , 1999.…”

Seasonal variations in elemental composition of aerosols in Xiamen, China

Rapid industrialization and economic take-off in coastal cities of China have placed great strain on the environment. In the this study, 40 aerosol samples were collected in the coast of Xiamen, Fujian province, west Taiwan Strait, P. R. China, from January to December 2003. The samples were analysed for the concentrations of elements (K, Ca, Na, Zn, Pb, W, Se, As, Ni, Ba, Nb, Ta, Zr, Hf, Th, U, Sr, REEs, etc.). All the elements display significant seasonal variations. The concentrations of most of the elements (except Na and Se) were high in January and February, abruptly decreased in March, kept relatively constant but low from April to August, and then gradually increased from September to December. This corresponds to the rainless climate and the influence of biomass burning from Southeast Asia in the winter and rain scavenging and the diffusion of typhoon in the summer. Thus, most of the elements have a good negative correlation with the monthly precipitation. The SEM/EDX studies indicate that the aerosols of Xiamen mainly consisted of soot grains, clay minerals, feldspar, gypsum, quartz, and biological particulates. The calculated enrichment factors indicate that Na and Br are derived from ocean, Pb, Zn, As, Sb, Se, W, and Ni are anthropogenic elements mainly derived from coal combustion, vehicle exhaust, and mining, and the other elements (i.e., Zr, Fe, Cr, Co, Rb, Sr, Cs, Ba, Hf, Ta, Th, U, and REEs) are crustal elements derived from weathered rocks and soil dust.The elemental concentrations of aerosols in Xiamen were compared with other cities, and the results indicate that Xiamen, like other coastal cities such as Qingdao, Dalian, Hong Kong, and Tokyo, has much lower concentrations of the elements such as Pb, Zn, and Cr than Beijing. The elemental deposition fluxes in Xiamen were also compared to other cities. The comparisons indicate that the elemental deposition fluxes in these cities are influenced not only by climatic characteristics (e.g., the precipitation and the sandstorm), but also by the industrial facility denseness.

“…The PTFE filter samples were also used for ionic species and crustal element analyses. The details of the chemical analyses are presented in separate papers in this special issue (Hsu et al 2004;Lung et al 2004). Besides, a redundant sample set was collected on pre-fired quartz filters for analyzing carbonaceous species (i.e., organic carbon and elemental carbon) in aerosols.…”
