The solute and particulate chemistry of background versus a polluted, black snowfall on the Cairngorm mountains, Scotland

The solute (Al, Br, Ca, Cl, Cu, Fe, I, Mg, Mn, Na, Pb, S and V) and particulate (Al, Ba, Br, Ca, Cl, Co, Cu, Dy, I, Mn, Na, Ti, U and V) chemistry of a relatively unpolluted snowfall, associated with a maritime airmass, is presented, to characterise background conditions for the region. The variability of the concentration of solute and the chemical composition of particulate material is investigated on an intra- and inter-site basis. The …
