Arsenic in atmospheric deposition at the Czech?Polish border: Two sampling campaigns 20 years apart

Popis výsledku v původním jazyce

Arsenic occurs in atmospheric deposition both in soluble and insoluble forms, mainly bound to fine aerosol particles (less than 2.5 ?m). Interception deposition (i.e. fog, dew and ice accretion) represents a specific type of atmospheric deposition, whichhas been much more contaminated with As than bulk deposition. This study compares the As amount and its binding forms in bulk and interception deposition in the winters of 1985 and 2004 in the Orlické hory mountains near the Czech-Polish border; sampledand analysed by the same methodology. The As concentrations in ice accretions decreased 16 times over the twenty year period (from 50 to 3 ?g l-1), while the pH values increased by 0.8 units. As concentrations in snow decreased from 15 ?g l-1 in 1984-1986 to b2 ?g L-1 in 2003-2005. This decline mirrored the considerable decrease in industrial emissions in Central Europe. Higher acidity of interception deposition (1 pH unit) in comparison with the bulk deposition was observed in both sam
