“…Similar to the other contributions, southwestern Iran is significantly at risk of dust deposition, which affects water quality, e.g., [36], soil productivity, e.g., [37], crop and live-stock, e.g., [38], human welfare, e.g., [7,39], political discontent, emigration, national costs, e.g., [40], and the economy, e.g., [41].…”

Investigation of Aeolian Dust Deposition Rates in Different Climate Zones of Southwestern Iran

Dust and atmospheric particles have been described in southwestern Iran primarily in terms of load, concentration and transport. The passive deposition, however, has been discussed inadequately. Therefore, the relationships between different climate zones in southwestern Iran and dust deposition rates were quantified between 2014 and 2017 using both space- (second modern-era retrospective analysis for research and applications, version 2 reanalysis model) and ground-based (eolian ground deposition rate) tools. In addition, the surface meteorological records, including the wind patterns favoring the occurrence of dust events, were examined. A hot desert climate (BWh), hot semi-arid climate (BSh), and temperate hot and dry summer climate (Csa) were identified as the three dominant climate regions in the study area, exhibiting the highest average dust deposition rates. In this study, correlations between the most relevant climate patterns and deposition rate weather parameters were found to describe a region’s deposition rate when a dust event occurred. Based on these results, the BSh and Csa regions were found to be associated with the seasonal cycle of dust events in March, April, and May, revealing that in the long run meteorological conditions were responsible for the varying dust deposition rates. Relatively, precipitation and temperature were the two major factors influencing dust deposition rates, not wind speed. Moreover, the peak seasonal deposition rates in the spring and summer were 8.40 t km−2 month−1, 6.06 t km−2 month−1, and 3.30 t km−2 month−1 for the BWh, BSh, and Csa climate regions, respectively. However, each of these climate types was directly related to the specific quantity of the dust deposition rates. Overall, the highest dust deposition rates were detected over the years studied were 100.80 t km−2 year−1, 79.27 t km−2 year−1, and 39.60 t km−2 year−1 for BWh, BSh, and Csa, respectively.

“…Small solid and dry particles below 75 µm in diameter [1] can be projected easily into the air by natural forces [2] and remain suspended in the Earth's atmosphere long enough to substantially affect weather and climate [3]. In fact, while particles are airborne, they impact the regional and global climate [4,5,6] and interact with solar and terrestrial radiation, depending on their mineralogical composition, which is determined by the source of deposition [7,8]. Although natural forces drive dust transport and deposition, dust transport processes can also be substantially constituted through human activities, including off-road driving [9,10], land use change [11,12,10,13], and anthropogenic activities in general [14,15].…”

“…In the long run, airborne dust is slowly removed from the atmosphere under the influence of gravity, land shape, land cover [16] such as vegetation that can obstruct dust movement effectively [17], and dry deposition, which consists of all deposition that accounts for gravitational settling not associated with precipitation [18]. In a similar manner, airborne particles function as condensation cores in the water cycle [6,19] and influence soil properties when they are deposited [4,5,20,21]. Aeolian dust can also contribute to the spreading of viruses [22] that also have large-scale effects on the soil, vegetation, animals, and humans [23,24,25].…”

In the last decade, the southwestern and western provinces of Iran have been heavily affected by aeolian dust deposition. As a result, the elemental composition of soil surfaces is influenced by dust transport as well as precipitation, wind speed and direction. The relationship between daily recorded dust events and the elemental composition of the dust is studied in this paper. Strong correlations were detected between dust deposition rate from most deposition sites (G01-G10, except for G05, G06) and the dust event frequency. Correlations of different strengths have been revealed between the dust event frequencies (DEF), and the elemental classification matrix based on airborne Metal Regulations. As expected, high correlation values indicate high concentration contributions of elemental values to the aerosol, such as Na, Mn, As, Pb, from large-scale depositions in the south including Cr and V in the west. These findings also suggest that the major contributors of V, Cr, Co, Ni, Cu, Zn, As, Se, Cd, Ba, and Pb in the elemental concentrations may depend on the meteorological situation and correlation magnitude are associated with elements emanating from local anthropogenic activities.
