3. The calcium carbonate of the stone dissolves in acid rain and reacts with sulphur dioxide in the air to form gypsum (calcium sulphate).
4. Natural sources of sulphur oxides include seaspray containing sulphate from oceans, organic compounds from bacterial decomposition of organic matter, reduction of sulphate in oxygen-depleted waters and soils, volcanoes, and forest fires (Record et al., 1982).

12. Supplies to 20,000 people were poisoned in Cornwall when a relief delivery driver accidentally pumped 20 tonnes of aluminium sulphate into the wrong tank at the Lowermoor treatment plant near Camelford on 6 July 1988.
