Acid Rain

The effects of atmospheric acidity on biology and the urban fabric were first noted in England about 150 years ago when a Scottish chemist found that local rainfall in Manchester was unusually acidic. Smith (1852) suspected a connection with sulphur dioxide from local coal-burning factories, and commented on the effects the deposits had on buildings and vegetation. It is Smith who is credited with the first use of the term ‘acid rain’.
