BACKGROUND In recent years, increasing dust storms from western neighboring countries of Iran influenced western and central parts of the country. In this case, level of concentration of atmospheric particulate matter greater than 10 μm (PM10) remained higher for several days compared to the levels before the event. Accordingly, Suspended particulate matters of dust storms in western Iran have ...

Atmospheric dust loadings have a significant influence on global climate by affecting air temperatures through the absorption and scattering of solar radiation. Many dryland basins are significant sources of aeolian dust, but our knowledge of how dust emissions from these systems are affected by ephemeral wetting events is either limited or poor. This research uses synergistic data sets (Total ...

Asian dust events result from displacement of atmospheric pollutants from the Chinese and Mongolian deserts, causing associated health issues throughout Northeast Asia. We investigated the relationship between skin symptoms in Asian dust events and contact allergy to Asian dust and associated metals. Increases in atmospheric levels of heavy metals such as Ni, Al, and Fe occurred during the seve...

[1] By combining reconstruction of airmass backtrajectories from dust deposition sites in Europe and measurements of the (Nd) isotopic composition of deposited dust particles, potential sources of different Saharan dust events can be identified. The study of ‘‘red dust’’ events collected in France allowed us to identify distinct North African source areas (e.g. Lybia vs. Mauritania). Surprising...

Dust is an environmental stressor and can become extensive in agricultural production systems. Thirty-six female, Spanish goats (average BW 21.1 kg, SEM = 1.31; age = 4 mo) were randomly assigned to simulated dust events or no dust, with or without tilmicosin phosphate treatment in a 2 x 2 factorial arrangement of treatments to determine effects on performance, rectal temperature, and leukocyte...

in this research, elemental and chemical characteristics of atmospheric dust particulates including major and trace elements in two synoptic meteorological stations (abadan and urmia cities) during dust events and ambient periods have been evaluated. results showed that during dust events to ambient periods in both stations, major elements including ca, mg, al and trace elements comprised p and...

During Asian dust events, a relatively high concentration of particulate matter is transported by wind from arid and semi-arid regions, such as the Gobi and Taklamakan deserts, to nearby countries, including China, Korea, and Japan. The dust particles contain various microorganisms, which can affect human health as well as the environmental microbe population. In the current study, we investiga...

BACKGROUND Dust events have long been recognized to be associated with a higher mortality risk. However, no study has investigated how prolonged dust events affect the spatial variability of mortality across districts in a downwind city. METHODS In this study, we applied a spatial regression approach to estimate the district-level mortality during two extreme dust events in Hong Kong. We comp...
