| Long description: |
The Galloway region of Scotland has been subjected to long-term acidic precipitation which has acidified soils and surface waters and damaged to aquatic ecology, although acidic deposition has decreased substantially during the last thirty years. Seven water quality surveys of 48 lochs in the Galloway region were conducted between 1979 and 1998. During the first 10 years there was a major decline in regional sulphate concentrations in the lochs, which would have increased acid neutralising capacity, but was offset by increasing levels of sea salt during the same period. During the next 10 years however, chloride concentrations dropped to 1979 levels and acid neutralising capacity increased despite little change in sulphate concentrations. Approximately 75% of the possible improvement in acid neutralising capacity has already occurred over this period (1979-1998). The role of acid deposition as a driving factor for change in water chemistry in the Galloway lochs has been affected by other variables, in particular factors related to climatic variation.
