Holocene atmospheric dust deposition in NW Spain

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...

The Holocene Stephen J . Burns atmospheric methane

Recent speleothem records from the tropics of both hemispheres document a gradual decrease in the intensity of the monsoons in the Northern Hemisphere and increase in the Southern Hemisphere monsoons over the Holocene. These changes are a direct response of the monsoons to precessiondriven insolation variability. With regard to atmospheric methane, this shift should result in a decrease in Nort...

Effects of atmospheric dust deposition on leaf chlorophyll fluorescence parameters of cow-tail shrubs (Smirnovia iranica) in the desert regions of Kashan, Iran

Peatland Microbial Communities as Indicators of the Extreme Atmospheric Dust Deposition

We investigated a peat profile from the Izery Mountains, located within the so-called Black Triangle, the border area of Poland, Czech Republic, and Germany. This peatland suffered from an extreme atmospheric pollution during the last 50 years, which created an exceptional natural experiment to examine the impact of pollution on peatland microbes. Testate amoebae (TA), Centropyxis aerophila and...
