“…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.

“…An Australian dust storm which lasted for only one day resulted in a 39% increase in hospital emergency admissions [21]. Increased asthma emergency admissions were associated with Saharan dust in the Caribbean island of Trinidad [22] and with Asian dust in Toyama, Japan [23].…”

“…Middleton et al (2008) noted a 10.4% increase in cases of cardiovascular disease in Cyprus during dust storm days. Lastly, on the Island of Trinidad in the Caribbean, Gyan et al (2005) show an increase in the daily hospital admission rates from 7.8 to 9.25 patients, while assuming climatic variables such as pressure and humidity to be constant. In the same area, Monteil (2008) notes a significant rise in the number of paediatric admissions in the seven days following major dust events.…”

This study aims to compare, on the one hand, the geographical distribution of the desert dust source areas, their contribution to quantities emitted into the atmosphere, the trajectories and the quantities deposited, with on the other hand the areas of research interest focused on the desert dust impacts on air quality and/or human health. Based on a systematic review of the literature using the ISI Web of Knowledge database, we found 231 articles published over the last decade on the desert dust impacts on air quality. Of these, 48% concerned Asian dust and 39% Saharan dust, with the remaining 13% divided between the other dust source areas. However, only one of these studies addressed the worsening air pollution in West Africa, even though it is very close to the Sahara, the greatest contributor to the global dust budget. Moreover, there have been very few studies (41) looking at the direct links between desert dust and human health; in this context too, no interest has been shown in West Africa. Yet this region is also among the areas in which morbidity rates have been noted to be far higher than those found in other regions of the world, and where respiratory infections alone account for more than 20% of the causes of infant mortality. This survey highlights a clear imbalance between those areas most exposed to dust and the most studied areas in terms of dust impacts. Given these findings and the often alarming results published about other regions of the world, we advocate a revival of interest in research on West Africa in order to achieve a better understanding of the desert dust impacts on air quality and health among the populations of this region.

“…Indeed, a 7.66% increase in respiratory diseases (+1.12% per 10 μg m −3 increase in PM 10 ) and a 4.92% increase in mortality was recorded (+0.72 per 10 μg m −3 increase in PM 10 ) during Mongolian dust outbreaks in Taipei, Taiwan (Chen et al, 2004). As far as the Caribbean island of Trinidad is concerned, African dust clouds have been associated with increased pediatric asthma accident and emergency admissions (Gyan et al, 2005). Surprisingly, however, no measurements of ambient air pollution levels near the Saharan dust sources are available (WHO, 2000;Baldasano et al, 2003).…”

It is now irrefutable that air pollution caused by large amounts of Total Suspended Particulates (TSP) and respiratory particulates or Particulate Matter less than 10 μm in aerodynamic diameter (PM 10 ) has numerous undesired consequences on human health. Air quality degradation far from the African continent, in the US and in Europe, caused by high concentrations of African dust, is seen as a major threat even though most of these countries are very distant from the Sahara. Surprisingly, no estimates of TSP or PM 10 levels near the Saharan dust source are available. Based on horizontal visibility observations which are reduced by the presence of dust in the atmosphere, TSP and PM 10 levels are estimated throughout the year 2000 at NouakchottAirport, Mauritania, using relations found in the literature. It appears that concentrations of particles are 10 . These very high particulate levels are likely to represent an important public health hazard and should be considered as a major environmental risk.
