A kinetic model of partially ionized complex plasmas is employed for the numerical analysis of low-frequency longitudinal modes for typical laboratory plasmas. The approach self-consistently includes the effects of plasma particle absorption on dust, collisions with neutrals and electron impact ionization. In addition to the typical dust acoustic mode, the results reveal the existence of a nove...

High desert dust concentrations raise concerns about adverse health effects on human populations. Based on a systematic literature review, this paper aims to learn more about the relationship between desert dust and human health in the world and to analyse the place of West Africa as a study area of interest. Papers focussing on the potential relationship between dust and health and showing qua...

of Science Topic: The ambient plasma environment and solar UV at the Moon cause the regolith on the lunar surface to become electrically charged [1–3]. This can result in the electrostatic transport of charged dust (< 10 μm) in the lunar exosphere, which has been observed to reach altitudes >100 km [4–6] and speeds of up to 1 km/s [7]. Value of Science Topic: From the Apollo era it is known tha...

We use a global chemical transport model (GEOS-Chem) to estimate the impact of transpacific transport of mineral dust on aerosol concentrations in North America during 2001. We have implemented two dust mobilization schemes in the model (GOCART and DEAD) and find that the best simulation of North American surface observations with GEOSChem is achieved by combining the topographic source used in...

The possible adverse impact on health presented at office workplaces by paper or paper dust (caused for example by the inhalation of paper dust during the shredding of files) has occasionally been a cause for concern in the recent past. Reports of possible paper dust emissions during the use of printers and photocopiers have also led to concerns. A literature study was therefore to be conducted...

Prevention and mitigation of acid rock drainage from mining are decisive for limiting environmental impact. Five by-products and industrial remnants (lime kiln dust, blast furnace slag, granulated blast furnace slag, cement kiln dust and fly ash) were investigated for their suitability to prevent acidity and metal(loid)s during leaching from highly sulfidic (50wt%, sulfide) waste rock in small ...

The effect of desert dust on cloud properties and precipitation has so far been studied solely by using theoretical models, which predict that rainfall would be enhanced. Here we present observations showing the contrary; the effect of dust on cloud properties is to inhibit precipitation. Using satellite and aircraft observations we show that clouds forming within desert dust contain small drop...
