Acid rain

Acid rain is rain droplets containing a solution of sulphuric oxides (SO2 and SO3) and nitrogen dioxide (NO2). Acid rain is any form of the atmospherically deposited acidic substance containing strong mineral acids of anthropogenic origin. It was reportedly first described in England by Robert Angus Smith in 1872. During the past twenty-five years, acid rain formally referred to as acid deposition, has been the focus of much political debate and scholarly research. Acid deposition occurs when important precursor pollutants, such as sulfur dioxide (SO2) and nitrogen oxides (NO^), mix with water vapour and oxidants in the atmosphere and fall back to earth in either wet or dry form.
