Thermal stability of arsenic complexes in soils.

The release of soil arsenic (As) in an unsaturated zone under oxidative conditions and at two temperatures simulating the seasonal effect (15 °C and 23 °C) was studied in four cultivated soils from the Elbe River catchment (Czech Republic, Central Europe). The soils with a low geogenic As background contained from 10 to 50 µg.g of As, mostly originating from atmospheric deposition in the past.

Environmental interaction of antimony and arsenic near busy traffic nodes.

Antimony (Sb) and arsenic (As) are elements with similar chemistry, toxicity and binding properties, but different environmental risks and prevailing anthropogenic sources. A significant source of Sb contamination is associated with braking in extremely loaded traffic areas, where the produced abrasion dust contains up to 5% wt. of SbS.

Processes affecting oxygen isotope ratios of atmospheric and ecosystem sulfate in two contrasting forest catchments in Central Europe.

Sulfate aerosols are harmful as respirable particles. They also play a role as cloud condensation nuclei and have radiative effects on global climate. A combination of delta18O-SO4 data with catchment sulfur mass balances was used to constrain processes affecting S cycling in the atmosphere and spruce forests of the Czech Republic.
