Scientists have been issuing
warnings about the havoc acid
rain could play with the environment. Now archaeologists have
also joined the campaign. They
have done so because the eruption
of Mount Katla - a volcano in
south-east Iceland - 3,000 years
ago, had let out enormous quantities of acid and killed a group
of Scottish settlers on the Island.
The remains of this group were
excavated when a road was being
laid in the region.
Says volcanologist John Gribben of the Institute of Earth Sciences, at of Wales in the University Aberystwyth, UK, "Mount Katlat erupts every 50 years and an eruption is overdue. And when it does happen, it could be catastrophic because the quality of air is already very bad an t e environment will not be able to absorb the acid load".
