Dust storms represent a major environmental challenge in the Middle East. The southwest part of Iran is highly affected by dust events transported from neighboring desert regions, mostly Iraqi plains and Saudi Arabia, as well local storms. This study analyzes spatio-temporal distribution days at five meteorological stations located southwestern covering period 22 years (from 1997 to 2018). codes (06, 07, 30 35) observations are analyzed each station, indicating that 84% not origin. average number maximizes June July (188 193, respectively), while activity weakens after August. exhibit large inter-annual variability, with statistically significant increasing trends all stations. Spatial distributions aerosol optical depth (AOD), loading, surface concentrations moderate resolution imaging spectroradiometer (MODIS) Modern-Era Retrospective analysis for Research Applications (MERRA-2) retrievals reveal high accumulation over surrounding regions. Furthermore, spatial (MODIS)-AOD trend (%) indicates heterogeneity during 2000–2018 ranging between −9% 9% (not significant). 2009 was most active year, followed 2011 2008, due prolonged drought conditions fertile crescent enhanced emissions this period. In these years, AOD much higher than 19-year (2000 2018), dustiest month about 25–30 station. highest were associated less precipitation, negative anomalies vegetation health index (VHI) normalized difference (NDVI) Iran, favorable dynamics triggering stronger winds.

IntroductionA dust storm is a harmful event in the environment and human health resulting from certain chemicals air that transcend predefined levels. Developing countries, such as Iran, suffer this basic threat (dust particles) to health. The purpose of research was evaluate effects PM10 particulate matter on mortality related cardiovascular diseases (CVD) year 2022-2023 Andimeshk City, with AirQ+ programmed.Material methodThe recommended approach for evaluating health, recognized by world organization (WHO), uses Air Quality Health Impact Assessment Software (Air Q 2.2.3). polluted information required model runs obtained Environmental Department Khuzestan. Khuzestan Meteorological Organization gave levels both dusty non-dusty days. numbers came Iranian Statistics Centre Ministry. data collected volumetric manner 2022-2023.ResultThe lowest concentration reported city belonged January 9 (14.19 μg/m3), while most day November 6 (5634.61 μg/m3). total monthly April, May, June, July, August, September, October, November, December, January, February respectively, 2917.9, 3227.82, 3175.89, 2966.24, 3520.46, 3393.1, 4671.07, 13121.26, 3042.63, 1851.67, 2627.52, 6758.12 μg/m3.ConclusionThe results study showed studied area terms particles. So, during year, only 8 days, did not exceed standard. One main reasons pollution Andimshek neighborhood province Iraq Saudi Arabia, which have dry areas storms.

Can global warming bring more dust?

Abstract In the late twentieth century, global mean surface air temperature especially on land is continuously warming. Our analyses show that of dust increased since 1980, using Modern-Era Retrospective Analysis version 2 for Research and Applications (MERRA-2) reanalysis data. This variation mainly contributed by increase outside core areas (i.e. high mass concentration region). The causes to result in variations are explored. areas, wind primary driving factor dust, both which no remarkable trends or decrease 1980. arid semi-arid North Middle Asia, warming impact causing increase. An accompanied enhancement atmospheric instability can trigger more upward motion bring dust. All 9 Earth System Models (ESMs) Aerosol Chemistry Model Intercomparison Project (AerChemMIP) reproduce reasonable spatial distribution seasonal cycle present day. But only a few models such as BCC-ESM1 GFDL-ESM4 simulate increasing trend similar MERRA-2. While middle latitudes Eurasian continent, presented most ESMs.

This study aims to increase our current knowledge on the concentration of particulate-bound mercury (PBM) in urban environments three Iranian cities, where high concentrations dust particles can act as carriers for transport and deposition. A total 172 samples were collected from Ahvaz, Asaluyeh, Zabol residential houses outdoor air analyzed content. Ahvaz is a highly industrialized city with large metallurgical plants, refineries, major oil-related activities, which assumed contribute elevated contents PBM this city. Very levels Hg contamination indoor calculated (Contamination Factor: CF > 6). Sampling sites Asaluyeh are influenced by emissions South Pars Gas Field. However, results revealed relatively lower low-to-moderate level contamination. likely ascribed content hydrocarbon gases than crude oil, addition absence metal smelting plants compared Ahvaz. Zabol, devoid industrial activity, presented lowest Indoor showed considerable potential cause non-carcinogenic health risk children, mainly through inhalation PBM, while other cities was below safe limits. The trend found order children adults all studied cities.
