Peatland Microbial Communities as Indicators of the Extreme Atmospheric Dust Deposition

Structure, inter-annual recurrence, and global-scale connectivity of airborne microbial communities.

Dust coming from the large deserts on Earth, such as the Sahara, can travel long distances and be dispersed over thousands of square kilometers. Remote dust deposition rates are increasing as a consequence of global change and may represent a mechanism for intercontinental microbial dispersal. Remote oligotrophic alpine lakes are particularly sensitive to dust inputs and can serve as sentinels ...

Recently Deglaciated High-Altitude Soils of the Himalaya: Diverse Environments, Heterogenous Bacterial Communities and Long-Range Dust Inputs from the Upper Troposphere

BACKGROUND The Himalaya with its altitude and geographical position forms a barrier to atmospheric transport, which produces much aqueous-particle monsoon precipitation and makes it the largest continuous ice-covered area outside polar regions. There is a paucity of data on high-altitude microbial communities, their native environments and responses to environmental-spatial variables relative t...

Human Health Risk Assessment of Cadmium Exposure in Dry Deposition of Atmospheric Dust (Uncertainty Analysis)

 Background and purpose: The atmospheric suspended particulate matter is a major route of human exposure to different kinds of environmental pollutants especially toxic heavy metals. The aim of this study was to assess the carcinogenic and non-carcinogenic risk of cadmium in dry deposition of atmospheric dust in Qazvin, Iran. Materials and methods: Glass traps were used for sampling dry atmosp...
