“…The comparison of PM 2.5 , PM 10 , and PM 2.5 /PM 10 ratios between this research and several related studies is shown in Table 2. This study and the compared studies all observed that the concentrations of PM 2.5 , PM 10 , and TSP in ADS periods were significantly higher than those in Non-ADS periods (Mori et al, 2003;Chen et al, 2004;Lee et al, 2009;Hong et al, 2010;Bian et al, 2011;Li et al, 2011;Wang et al, 2011;Zhao et al, 2011;Chuang et al, 2012); however, we also found that the PM 2.5 /PM 10 value decreased in the ADS period because of the increase of dust (PM 2.5-10 ) in this study. This phenomenon is similar to those in several studies, indicating that ADS increased the regional concentrations of atmospheric particles (especially that of coarse particulate matter (PM 2.5-10 )) greatly (Chen et al, 2004;Cheng et al, 2005;Cheng et al, 2007;Cheng et al, 2009).…”

This study explores the effects of an Asian dust storm (ADS) and Southeast Asian biomass burning on the composition of atmospheric aerosols in the coastal area of southern Taiwan in spring 2010. Coarse and fine particles were collected using two manual dichotomous samplers (Dichots) that were equipped with Teflon and Quartz filters. The results reveal that the concentrations of PM 10 and PM 2.5 in the ADS period were about twice those before and after this. More than half of water-soluble ions in coarse particles (PM 2.5-10 ) were Cl -and Na + (sea salt), while 70% of water-soluble ions of fine particles were SO 4 2-and NH 4 + (secondary aerosols). The OC/EC ratios of PM 2.5 and PM 2.5-10 were all above 2.0. Over 98% of the metals in coarse and fine particles were crustal elements (98.1-99.1%), and over 60% of the metals in PM 10 were in coarse particles (PM 2.5-10 ). The water-soluble ion, EC, OC, and metal contents in PM 2.5 all exceeded those in PM 2.5-10 . The ADS was associated with higher concentrations of water-soluble ions in PM 2.5 and PM 2.5-10 than was the non-ADS period, except for K + in PM 2.5-10 . ADS most increased the Ca 2+ content and concentration, causing a rise in the average concentrations of Ca 2+ in coarse and fine particles by factors of 3.0 and 3.2, respectively. In the ADS period, although the OC and EC concentrations of coarse and fine particles increased, the OC and EC contents in these particles decreased. The ADS period was associated with higher metal contents in coarse and fine particles than the non-ADS period, and the increase in PM 2.5-10 (more than 2%) exceeded that in PM 2.5 . In PM 2.5-10 and PM 2.5 , the Ca and Ni contents increased the most, respectively. In addition, the concentrations of the water-soluble ions, EC, OC, and metals in PM 2.5-10 and PM 2.5 increased, but their contents decreased, while the contents of the other constituents (= total -(water-soluble ions + EC + OC + metals)) in PM 2.5-10 and PM 2.5 increased. It is also found that Southeast Asian biomass burning is related to the deterioration of the air quality of southern Taiwan.

“…An estimated effect of 3% decline in daily forced expiratory volume (FEV1) change was observed for every 10 µg/m 3 increase in ambient PM 10 level [48]. Other studies showed a strong association between dust events and asthma admissions in Japan [23], Trinidad [22], Taiwan [49], South Korea [50,51] and southern Europe [52].…”

Health Impact Assessment Associated with Exposure to PM10 and Dust Storms in Kuwait

Abstract:Little information is available on the assessment of health impact concerning the Middle Eastern dust storms and PM 10 concentration levels despite the aridity of the region and frequent dust storms occurring in this part of the world. A prospective study was conducted to determine the association between dust particles and morbidity and mortality rates for respiratory and cardiovascular diseases in Kuwait. Spearman and Pearson's correlations were used to identify such associations. Results revealed a significant correlation between dust storms, suspended dust and rising dust (p < 0.01). Correlation between the occurrence of respiratory and cardiovascular diseases and dust storms showed that PM 10 concentrations were significantly correlated with bronchial asthma at the 0.05 level (Pearson r = 0.292). Significant correlations at the 0.01 level were shown between bronchial asthma and both acute lower respiratory tract infection (r = 0.737) and acute upper respiratory tract infection (r = 0.839). Respiratory and cardiovascular mortality rates were both equal to 0.62 per 10,000 persons, each corresponding to 8.7% proportionate mortality rate. This study provides a good evidence of the consistent relationship between dust storm events, PM 10 concentration levels, and respiratory diseases.

“…Trace metals account for only a small fraction of PM mass concentrations, but they can adversely impact human health (e.g., Lippmann et al, 2006;Hong et al, 2010). As some emission sources release specific trace elements, these elements can serve as useful source markers in PM source apportionment studies Peltier and Lippmann, 2010;Han et al, 2005;Harrison et al, 2012;Karanasiou et al, 2009;Ondov et al, 2006;Querol et al, 2007;Viana et al, 2008;Yu et al, 2013).…”

Sources of PM<sub>2.5</sub> carbonaceous aerosol in Riyadh, Saudi Arabia

Abstract. Knowledge of the sources of carbonaceous aerosol affecting air quality in Riyadh, Saudi Arabia, is limited but needed for the development of pollution control strategies. We conducted sampling of PM 2.5 from April to September 2012 at various sites in the city and used a thermo-optical semi-continuous method to quantify the organic carbon (OC) and elemental carbon (EC) concentrations. The average OC and EC concentrations were 4.7 ± 4.4 and 2.1 ± 2.5 µg m −3 , respectively, during this period. Both OC and EC concentrations had strong diurnal variations, with peaks at 06:00-08:00 LT and 20:00-22:00 LT, attributed to the combined effect of increased vehicle emissions during rush hour and the shallow boundary layer in the early morning and at night. This finding suggested a significant influence of local vehicular emissions on OC and EC. The OC / EC ratio in primary emissions was estimated to be 1.01, close to documented values for diesel emissions. Estimated primary organic carbon (POC) and secondary organic carbon (SOC) concentrations were comparable, with average concentrations of 2.0 ± 2.4 and 2.8 ± 3.4 µg m −3 , respectively.We also collected 24 h samples of PM 10 onto quartz microfiber filters and analyzed these for an array of metals by inductively coupled plasma atomic emission spectroscopy (ICP-AES). Total OC was correlated with Ca (R 2 of 0.63), suggesting that OC precursors and Ca may have similar sources, and the possibility that they underwent similar atmospheric processing. In addition to a ubiquitous dust source, Ca is emitted during desalting processes in the numerous refineries in the region and from cement kilns, suggesting these sources may also contribute to observed OC concentrations in Riyadh. Concentration weighted trajectory (CWT) analysis showed that high OC and EC concentrations were associated with air masses arriving from the Persian Gulf and the region around Baghdad, locations with high densities of oil fields and refineries as well as a large Saudi Arabian cement plant. We further applied positive matrix factorization to the aligned dataset of EC, OC, and metal concentrations (Al, Ca, Cu, Fe, K, Mg, Mn, Na, Ni, Pb, and V). Three factors were derived and were proposed to be associated with oil combustion, industrial emissions (Pb based), and a combined source from oil fields, cement production, and local vehicular emissions. The dominant OC and EC source was the combined source, contributing 3.9 µg m −3 (80 %) to observed OC and 1.9 µg m −3 (92 %) to observed EC.
