Abstract

Samples of snow were collected from three sites in Morocco, and on a transection Tenerife in the Canary Islands. As expected the snows were less acidic than those of Scandinavia. Results from Tenerife suggest that the pH of pure snow in remote locations lies close to the value expected of water in equilibrium with atmospheric carbon dioxide. This pH may be lowered by the presence of acids of anthropogenic origin as in Norwegian snows or increased by alkaline dusts as is found in the Moroccan samples. The amounts of marine salt in the Tenerife samples were less than expected, but large amounts of sea-salt could slightly increase the pH. It would seem that despite the magnitude of global anthropogenic emissions of sulphur dioxide, they are presently not large enough to affect significantly the acidity of snow in North Africa. -L. F.
