Dust is a common weather phenomenon in the Arabian Gulf, which has severely affected economy and health. Sand and dust storms (SDS) trajectories in the Arabian Gulf were temporally and spatially monitored from March 2000 to March 2017. Eight major SDS trajectories were detected from satellite images. The dust storms trajectories were categorized according to shape and size into three main types with 12 subtypes in the region. The annual transported dust amount into the Arabian Gulf was estimated by 89.1 million metric tons, which is about 10,330 metric tons per cubic kilometer of water volume. In comparison to other seas and oceans, the amount of dust deposited into the Arabian Gulf water body volume is the highest. Dust deposited in the coastal regions within the Arabian Gulf are originated from Mesopotamian Flood Plain (MFP), Ahwaz (HZ), Ahwar (HR) and Baluchistan Desert (BSH) and characterized by physical parameters and composition. Such physical characterization of the trajectories of SDS, and of the properties of particles transported in the Arabian Gulf can be helpful to assess and mitigate the environmental impact of future similar events.

“…Findings of this study suggest that there are strong associations between dust storms and PM 10 and morbidity rates of asthma and acute upper and lower tract infections. The risk for various outcomes has been shown to increase with exposure, and there is little evidence to suggest a threshold below which no adverse health effects would be anticipated [3]. However, it may be worthwhile to further investigate the health impact of dust storm events across Kuwait, and such further evaluation can improve our understanding of the health impact of dust storms and PM 10 pollutants.…”

“…The northern region of the Arabian region is characterized by complex dust storm trajectories where they pass through the western desert of Syria and Iraq toward the Mesopotamian flood plain reaching the northeastern region of the peninsula into Kuwait at a dust fallout rate of 61.4 tons per km 2 per year, where fallen dust compromises 37% of sand particles [2,3]. A particular feature of blown dust is its extreme particulate matter intensity that increases the ambient air dust concentrations for several days.…”

“…Little information is available on the assessment of health impact about dust storms and PM 10 concentration levels in the Middle Eastern despite the facts that the region experiences frequent dust storms [24] and is considered a major source of global dust [1, 3,25]. Many studies from Iran have demonstrated a positive association between dust particles and total mortality including cardiovascular and respiratory mortalities [26][27][28][29][30][31][32][33][34] and hospital admissions for cardiovascular and respiratory diseases [35,36].…”

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.

Sedimentation of harmful dust by means of ultrasonic waves and additional disperse phase

et al. 2015

The harmful effect on the health of superfine dust in industry is a serious problem. An especially important and complex task is the development of new methods for sedimentation of dust particles with a characteristic size of less than 10 μm. The solution offered by the authors involves a combined method of impact on industrial dust using highfrequency acoustic fields and spraying of a superfine water aerosol. Acoustic radiation sources are successfully applied to cleaning rooms from dust having fairly large particle sizes (10 μm and larger). The sedimentation of fine aerosols (particle diameter of 1-10 μm) is a more complicated challenge. The paper is devoted to substantiation of the acoustic sedimentation method for such aerosols. Good results were achieved when additional disperse phase was applied together with the ultrasonic source. Calculation results according to the mathematical model for coagulation and sedimentation, based on Smoluchowski's equation, taking into account evaporation of liquid droplets, are given. Results of the experimental and theoretical study of the processes of acoustic sedimentation of superfine aerosols are presented. Recommendations are offered for the use of sources of ultrasonic radiation and sprayers of water aerosol for optimum removal of dust from workplace air.
