“…Springtime marks the period in Korea when there are Asian dust storms (Cho, 1980;Kim et al, 1986;Chun et al, 2001aChun et al, , 2001bKim, 2008). These dust storms have been associated with increased cardiopulmonary emergency visits (Chan et al, 2008;Kang et al, 2012) and increased respiratory symptoms of subjects with asthma (Park et al, 2005). The year of this study (2012) was unique in that there were no major dust events.…”

Fungal spores are widespread and common in the atmosphere. In this study, we use a metagenomic approach to study the fungal diversity in six total air samples collected from April to May 2012 in Seoul, Korea. This springtime period is important in Korea because of the peak in fungal spore concentration and Asian dust storms, although the year of this study (2012) was unique in that were no major Asian dust events. Clustering sequences for operational taxonomic unit (OTU) identification recovered 1,266 unique OTUs in the combined dataset, with between 223-396 OTUs present in individual samples. OTUs from three fungal phyla were identified. For Ascomycota, Davidiella (anamorph: Cladosporium) was the most common genus in all samples, often accounting for more than 50% of all sequences in a sample. Other common Ascomycota genera identified were Alternaria, Didymella, Khuskia, Geosmitha, Penicillium, and Aspergillus. While several Basidiomycota genera were observed, Chytridiomycota OTUs were only present in one sample. Consistency was observed within sampling days, but there was a large shift in species composition from Ascomycota dominant to Basidiomycota dominant in the middle of the sampling period. This marked change may have been caused by meteorological events. A potential set of 40 allergyinducing genera were identified, accounting for a large proportion of the diversity present (22.5-77.2%). Our study identifies high fungal diversity and potentially high levels of fungal allergens in springtime air of Korea, and provides a good baseline for future comparisons with Asian dust storms.

“…In contrast, 5 of the 11 studies concluding that there is no relationship between dust and health were carried out before 2007. It has been suggested that, for studies in Asia, one major reason why dust storms are either not associated with mortality or had no consistent association with hospital admissions is that, to date, studies looking at the impact of dust on health have not documented well the area in which, and the time in which, dust storms take place (Chan et al 2008). It can be expected that a short-duration dust storm taking place during a wet period may have little significant impact on health in downwind reach areas.…”

“…Among the 50 studies listed in Table 1, satellite images (MODIS, NOAA/AVHRR) were used in two cases, but in combination with other data (Chan et al 2008;Goto et al 2010). In one study, Saharan dust days (SDDs) were defined by combining light detection and ranging (LIDAR) observations and analyses from operational models (Mallone et al 2011).…”

“…Studies reported that, in Korea, dust events are associated with increased daily mortality (Lee et al 2007), stroke, asthma Yoo et al 2008) and atopic asthma (Hwang et al 2008). Dust storms also have an impact on cardiopulmonary emergency admissions (Chan et al 2008) and on the respiratory symptoms of subjects with bronchial asthma (Park et al 2005) in Taiwan. In addition, a statistically significant association has been recorded between Asian dust events and daily pneumonia admissions 1 day after the event .…”

Desert dust impacts on human health: an alarming worldwide reality and a need for studies in West Africa

et al. 2012

High desert dust concentrations raise concerns about adverse health effects on human populations. Based on a systematic literature review, this paper aims to learn more about the relationship between desert dust and human health in the world and to analyse the place of West Africa as a study area of interest. Papers focussing on the potential relationship between dust and health and showing quantitative analyses, published between January 1999 and September 2011, were identified using the ISI Web of Knowledge database (N050). A number of adverse health effects, including respiratory, cardiovascular and cardiopulmonary diseases, are associated with dust. This survey highlights obvious dust impacts on human health independently of the study area, health outcomes and method. Moreover, it reveals an imbalance between the areas most exposed to dust and the areas most studied in terms of health effects. None of these studies has been conducted in West Africa, despite the proximity of the Sahara, which produces about half of the yearly global mineral dust. In view of the alarming results in many parts of the world (Asia, Europe, America), this paper concludes by stressing the importance of carrying out impact studies of Saharan dust in West Africa, where dust events are more frequent and intense than anywhere else.

“…Epidemiological studies of ASD in humans have shown that ambient ASD particles are associated with an increase in pulmonary (Bell, Levy, and Lin 2008;Chan et al 2008;Cheng et al 2008;Chiu et al 2008;Lai and Cheng 2008) and cardiovascular problems (Bell, Levy, and Lin 2008;Chan et al 2008;Yang, Cheng, and Chen 2009) and an increase in daily mortality in Korea (Hwang et al 2005;Kwon et al 2002;Lee, Son, and Cho 2007) and Taiwan (Chen et al 2004). The frequency and scale of dust events giving rise to ASD aerosols have increased rapidly in the east Asian region since 2000 (Mori et al 2003).…”

Pathological Study of Chronic Pulmonary Toxicity Induced by Intratracheally Instilled Asian Sand Dust (Kosa)

Asian sand dust (ASD) events are associated with an increase in pulmonary morbidity and mortality. The number of ASD events has increased rapidly in the east Asian region since 2000. To study the chronic lung toxicity of ASD, saline suspensions of low doses (200 and 400 mg) and high doses (800 and 3,000 mg) of ASD were intratracheally instilled into ICR mice. Animals were sacrificed at 24 hr, 1 week, or 1, 2, or 3 months after instillation. Histopathological examination revealed that ASD induced acute inflammation at 24 hr after instillation. The acute inflammation was transient and subsided at 1 week and 1 month after instillation. At 2 and 3 months after instillation, focal infiltration of lymphocytes with accumulation of epithelioid macrophages, which is a suggestive finding of transformation to granuloma, and granuloma formation were occasionally observed. Aggregation of macrophages containing particles was observed in the pulmonary lymph nodes at 3 months after instillation in high-dose groups. Prolonged inflammatory foci (granuloma) and presence of ASD particles in pulmonary lymph nodes would have a chance to induce immunological modulation leading to adverse health effects in the exposed animals.
