“…As examples, high free-Fe/Al and low Ca/Al have been reported for dust outbreaks from Sahel, whereas high Ca/Al were measured for Saharan dust outbreaks (Chester et al, 1971, Chester et al, 1993; Chiapello et al, 1997; Moreno et al, 2006, among others), and high Ca/Al was used as a tracer of Western China deserts in PMx from Beijing, while lower ratios pointed to a Northern China desert origin (Yuan et al, 2008). Other tracers of source regions for dust are stable isotopes and radionuclides (Papastefanou et al, 2001; Aba et al, 2018; Goudie and Middleton, 2006, and references therein; among others) (see also section on compositional patterns of dust).…”

We review the major features of desert dust outbreaks that are relevant to the assessment of dust impacts upon human health. Our ultimate goal is to provide scientific guidance for the acquisition of relevant population exposure information for epidemiological studies tackling the short and long term health effects of desert dust. We first describe the source regions and the typical levels of dust particles in regions close and far away from the source areas, along with their size, composition, and bio-aerosol load. We then describe the processes by which dust may become mixed with anthropogenic particulate matter (PM) and/or alter its load in receptor areas. Short term health effects are found during desert dust episodes in different regions of the world, but in a number of cases the results differ when it comes to associate the effects to the bulk PM, the desert dust-PM, or non-desert dust-PM. These differences are likely due to the different monitoring strategies applied in the epidemiological studies, and to the differences on atmospheric and emission (natural and anthropogenic) patterns of desert dust around the world. We finally propose methods to allow the discrimination of health effects by PM fraction during dust outbreaks, and a strategy to implement desert dust alert and monitoring systems for health studies and air quality management.

“…This led to an increased potential to collapse the Fertile Crescent (namely Iraq and Syria). In the Middle East, and especially in the Arabian Peninsula, a pronounced variability in dust activity was reported with an abrupt regime shift from an inactive dust period (1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005) to an active dust period (2007)(2008)(2009)(2010)(2011)(2012)(2013) (Aba et al, 2018), which was linked to climate change and global warming impacts in the 2000s (Notaro et al, 2015;Doronzo et al, 2016 and. The increased dust episodes and atmospheric dust concentrations on top of the atmosphere have a significant impact on the albedo and short-wave radiation over the African and Arabian regions leading to higher surface reflection (Satheesh et al, 2006), especially in Palestine (Singer et al 2003), Iraq (Al-Hemoud et al 2020), Kuwait (Al-Dousari 2009.…”

In this study, the particulate matter mass (PM10 and PM2.5) concentrations we measured during May 2018-March 2019 in an urban atmosphere of Amman, Jordan. The results showed that the annual mean PM10 concentration was 64±39 µgm-3 and the PM2.5/PM10 ratio was 0.8±0.2. According to the Jordanian Air Quality standards (JS-1140/2006), the observed PM10 annual mean value was below the limit value but that of the PM2.5 was three times higher than the corresponding limit value. However, both exceeded the World Health Organization (WHO) air quality guideline values. In a larger perspective, the annual mean PM10 concentrations in Jordan were lower than what was reported in other cities in the Middle East but were higher when compared to other Mediterranean cities. During the measurement period, Jordan was affected by Sand and Dust Storm (SDS) episodes on 14 days. The source origins of these dust outbreaks were traced back to North Africa, the Arabian Peninsula, and the Levant. The 24-hour PM10 concentrations during these SDS episodes ranged between 108 and 188 µgm-3 , which was about 3-6 times higher than the mean values during clean conditions (~33 µgm-3).

“…The highest 210 Pb concentrations were observed in spring (41.4 Bq m −2 ) and the lowest in fall (1.8 Bq m −2 ), which is quite consistent with the dust loadings of the corresponding months. However, the wet precipitation associated with Sarrayat and Koss played a major role in obtaining these high deposition fluxes (Aba et al 2016(Aba et al , 2018Al-Dousari et al 2016). The monthly deposition ratios of 7 Be and 210 Pb are largely consistent with the dust loading in the corresponding months.…”

Temporal and Spatial Distribution of Radionuclides in Dust Fallout. The depositional fluxes of the natural radionuclides (40K, 210Pb, and 7Be) and the man-made radionuclides (137Cs) have been calculated using efficiency calibrated ultra-low background gamma spectrometry in nine sampling sites covering Kuwait. Maps showing high and low concentrations of radionuclides distribution among Kuwait.
