Elements, 2010
Global dust events have been part of much of Earth's history. As in the geological past, mineral dust deflated off weathered crustal material in arid regions is continually being lofted kilometres into the atmosphere, where it circles the globe until physical and chemical processes favour precipitation in the ocean or on land.

Toxic Potential of Mineral Dusts
Elements, 2007In this outline of the most prominent factors involved in particle toxicology, we highlight the differences in the toxic potential among airborne particles and describe what is known about the most notorious toxic agents, such as silica and asbestos. The various biological paths and, consequently, the different outcomes in the health risks associated ...

Refractory Minerals in Interplanetary Dust
Science, 1986A newly studied interplanetary dust particle contains a unique set of minerals that closely resembles assemblages in the refractory, calcium- and aluminum-rich inclusions in carbonaceous chondrite meteorites. The set of minerals includes diopside, magnesium- aluminum spinel, anorthite, perovskite, and fassaite.

On mineral dust hygroscopicity
2021<p>Despite its importance, hygroscopicity of mineral dust aerosol remains highly uncertain. In this work, we investigated water adsorption and hygroscopicity of different mineral dust samples at 25&#8201;&#8728;C, via measurement of sample mass at different relative humidity (RH, up to 90&#8201;%) using a vapor ...

Tubercle and Lung Disease, 1992
The mineral dust diseases, also called the pneumoconioses, comprise a wide spectrum of conditions ranging from diseases characterized by diffuse collagenous pulmonary reactions to relatively small lung burdens of bioactive dusts (e.g. silicosis, asbestosis) to diseases characterized by largely non-collagenous reactions in the face of heavy lung dust ...

High-resolution mineral dust modeling
2022<p>Dust emissions are linked with wind forces through a non-linear relationship. As a result, small errors in modelled wind speed lead to large errors in modelled dust emission. Dust models usually show satisfactory behaviour when dust outbreaks are caused by synoptic-scale weather systems.

There is scientific consensus that human activities have been altering the atmospheric composition and are a key driver of global climate and environmental changes since pre-industrial times (IPCC, 2013). It is a pressing priority to understand the Earth system response to atmospheric aerosol input from diverse sources, which so far remain one of the ...

Chemistry and Photochemistry of Mineral Dust Aerosol
Annual Review of Physical Chemistry, 2008It has become increasingly clear that heterogeneous and multiphase chemistry of tropospheric aerosols can change the chemical balance of the atmosphere. In this review, we focus on recent laboratory studies of the heterogeneous and multiphase chemistry and photochemistry of mineral dust aerosol, a large mass fraction of the tropospheric aerosol ...
