Black acidic snow in the remote Scottish Highlands
TL;DR: In this article, the authors present the first documented case remote from major pollution sources of a distinctive black, acid snowfall episode with pH 3.O. The particulate deposit was very large and consisted of ∼29% carbon; the remaining fraction included particles which could be identified as coal fly-ash.

Trace elements in snow samples from the Scottish Highlands: sources and dissolved/particulate distributions
TL;DR: In this paper, fresh snow samples were collected throughout a season at a high altitude (1080m) site in the NE Scottish Highlands and analysed for 14 trace elements in addition to the major element composition Enrichment factors suggests three significant sources of the different elements, ie crust, seawater and anthropogenic inputs.

Spatial variability in the chemical composition of snowcover in a small, remote, scottish catchment
TL;DR: In this paper, the authors show that the distribution of the concentration of major ions in snow cover is better described by the lognormal distribution and that both vertical and horizontal variability is observed in the chemical content of within-pack snows.

The impact of a single black snowfall on streamwater chemistry in the Scottish Highlands
TL;DR: In this article, the authors present the streamwater chemistry during two acid-flush events with minimum recorded pH of 4.25 and 4.4 in upland Britain, in the Scottish Highlands.

Geochemical studies in a remote scottish upland catchment ii. streamwater chemistry during snow-melt
TL;DR: In this paper, an upland catchment in the Cairngorm Mountains (Scotland) at the time of the spring-thaw is associated with an increase in stream discharge and raised concentrations of both major ions (Ca, Mg, Na, Cl, N03, and SO) and trace-elements (Al, Cd, Cu, Fe, Mn, and Pb), in addition to H+.
