“…During an ADS, the PM2.5 level is 61.93µg/m 3 , while that on comparison days is 48.87µg/m 3 . Our findings are the same as those of Kamouchi et al [25] and Kwon et al [26]. Yet the levels of combustion particulates (CO and NO2) do not differ during an ADS, a result that matches that of Yang et al [27].…”

Abstract:A case-crossover study examined how PM2.5 from Asian Dust Storms (ADS) affects the number of emergency room (ER) admissions for cardiovascular diseases (CVDs) and respiratory diseases (RDs). Our data indicated that PM2.5 concentration from ADS was highly correlated with ER visits for CVDs and RDs. The odds ratios (OR) increased by 2.92 (95% CI: 1.22-5.08) and 1.86 (95% CI: 1.30-2.91) per increase 10 µg/m 3 in PM2.5 levels, for CVDs and RDs, respectively. A 10 µg/m 3 increase in PM2.5 from ADSs was significantly associated with increase in ER visits for CVDs among those 65 years of age and older (an increase of 2.77 in OR) and for females (an increase of 3.09 in OR). In contrast, PM2.5 levels had a significant impact on RD ER visits among those under 65 years of age (OR=1.77). The risk of ER visits for CVDs increased on the day when the ADS occurred in Taiwan and the day after (lag 0 and lag 1); the corresponding risk increase for RDs only increased on the fifth day after the ADS (lag 5). In Taiwan's late winter and spring, the severity of ER visits for CVDs and RDs increases. Environmental protection agencies should employ an early warning system for ADS to reduce high-risk groups' exposure to PM2.5.

“…Dust storms in Taiwan had a 7.66% increase in the risk for respiratory diseases [17], congestive heart failure [8] and daily pneumonia hospital admissions [9]. Asian dust storms had a 4.1% increase in the rate of deaths from cardiovascular and respiratory causes in Seoul, South Korea [18] and a significant increase in respiratory hospitalizations in China [19,20]. Dust blown from the Sahara to the Eastern Mediterranean resulted in an increase in all-cause hospital admissions including respiratory and cardiovascular diseases in Nicosia, Cyprus [7].…”

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

et al. 2018

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.

“…Longrange transport in East Asia has been studied to understand the pathways and impacts of dust storms, known as Asian dust or yellow sand (Chun et al, 2001;Chung, 1992;Iwasaka et al, 1983;Kim et al, 2008;Kwon et al, 2002; H. C. Kim et al: Regional contributions to particulate matter concentration 2013), and acidic deposition processes (Larssen et al, 1999;Park et al, 2005). Recently, studies have been conducted on the chemical processes underlying PM formation, including the secondary formation of PM components and the transport patterns related to synoptic meteorology (Chang et al, 2010).…”

Regional contributions to particulate matter concentration in the Seoul metropolitan area, South Korea: seasonal variation and sensitivity to meteorology and emissions inventory

et al. 2017

Abstract. The impact of regional emissions (e.g., domestic and international) on surface particulate matter (PM) concentrations in the Seoul metropolitan area (SMA), South Korea, and its sensitivities to meteorology and emissions inventories are quantitatively estimated for 2014 using regional air quality modeling systems. Located on the downwind side of strong sources of anthropogenic emissions, South Korea bears the full impact of the regional transport of pollutants and their precursors. However, the impact of foreign emissions sources has not yet been fully documented. We utilized two regional air quality simulation systems: (1) a Weather Research and Forecasting and Community Multi-Scale Air Quality (CMAQ) system and (2) a United Kingdom Met Office Unified Model and CMAQ system. The following combinations of emissions inventories are used: the Intercontinental Chemical Transport Experiment-Phase B, the Intercomparison Study for Asia 2010, and the National Institute of Environment Research Clean Air Policy Support System. Partial contributions of domestic and foreign emissions are estimated using a brute force approach, adjusting South Korean emissions to 50 %. Results show that foreign emissions contributed ∼ 60 % of SMA surface PM concentration in 2014. Estimated contributions display clear seasonal variation, with foreign emissions having a higher impact during the cold season (fall to spring), reaching ∼ 70 % in March, and making lower contributions in the summer, ∼ 45 % in September. We also found that simulated surface PM concentration is sensitive to meteorology, but estimated contributions are mostly consistent. Regional contributions are also found to be sensitive to the choice of emissions inventories.
