A new dust cycle model with dynamic vegetation: LPJ-dust version 1.0

Europeanglacial dust deposits: Geochemical constraints on atmospheric dust cycle modeling

For a long time global paleodust numerical simulations have greatly underestimated dust sources other than modern deserts. Recent modeling experiments incorporating glaciogenic sources of dust have positively improved the agreement between model and paleodust data. This highlights the importance of accurately representing all areas potentially subjected to deflation during an investigated inter...

Simulating the Martian dust cycle with a finite surface dust reservoir

Dust in elliptical galaxies: a new dust mass evaluation

In order to investigate the nature and origin of dust in elliptical galaxies, a method for the dust mass evaluation, which accounts for the dust temperature distribution, is here presented and discussed. The derived dust masses turn out to be a factor 2-6 larger than those obtained with the single temperature approximation. A correlation between the far-infrared and the blue luminosity has been...

The effects of dust on vegetation--a review.

An increase in quarrying, open-cast mining and road traffic suggest that dust deposition onto vegetation may be increasing. This review describes the physical and chemical characters of a range of dust types. The effects of dust on crops, grasslands, heathlands, trees and woodlands, arctic bryophyte and lichen communities are identified. Dust may affect photosynthesis, respiration, transpiratio...

A new model for toxicity of uranium dust

There is growing evidence in scientific literature, resulting both from in vitro and in vivo analyses, that current models of the mechanisms of toxicity of uranium dust are not fully satisfactory. They should be refined in order to obtain more effective responses and predictions regarding health effects. A review of the most recent findings in the field of uranium toxicity is carried out, and a...
