The effects of acid rain on stone. Face of a stone gargoyle,badly corroded by centuries of rain and,more recently,acid rain. Limestone features such as these are particularly prone to acid attack. Normal rain is slightly acidic,mainly carbonic acid. In post-industrial societies,however,sulphuric and nitric acids are normally present. Sulphuric acid comes from sulphur oxides generated by industry and fossil- fuel power stations. Nitric acid comes from motor vehicle exhaust fumes as nitrogen oxides. Photographed in Paris | |
