In that year, he discovered the relationship between acid rain and atmospheric pollution in Manchester, England.Although it was discovered in the 1800s, acid deposition did not gain significant public attention until the 1960s and the term acid rain was coined in 1972.When these gases are discharged into the atmosphere they react with the water, oxygen, and other gases already present there to form sulphuric acid, ammonium nitrate, and nitric acid.

Essay on Acid Rain: Definition, Causes, Adverse Effects and Control! Smith in 1872 from his studies of air in Manchester, England.
The widespread occurrence of acid rain was recognized only in 1980.
Wet deposition: Wet deposition of acids occurs when any form of precipitation (rain, snow, and so on) removes acids from the atmosphere and delivers it to the Earth’s surface.
This can result from the deposition of acids produced in the raindrops (see aqueous phase chemistry above) or by the precipitation removing the acids either in clouds or below clouds.
Acid rain is caused by emissions of sulphur dioxide and nitrogen acids, which react with the water, smell molecules in the atmosphere to produce acids.
Governments have made efforts since the 1970s to reduce the release of sulphur dioxide into the atmosphere with positive results.At p H lower than 5 most fish eggs will not hatch and lower p Hs can kill adult fish.As lakes and rivers become more acidic biodiversity is reduced.Liquids with a p H less than 7 are acidic, and those with a p H greater than 7 are alkaline.“Clean” or unpolluted rain has an acidic p H, but usually no lower than 5.7, because carbon dioxide and water in the air react together to form carbonic acid, a weak acid.Parts of India such as North East, Coastal regions of Kerela, Orissa, Bihar, and West Bengal have reported decline in fertility of soil due to reduced p H of soil (increased in acidity).Acid rain is the phenomenon of wet and dry acidic deposition.Acid rain is a rain or any other form of precipitation that is unusually toxic, meaning that it possesses elevated levels of hydrogen ions (low p H).It can have harmful effects on plants, aquatic animals, and infrastructure.Acid rain has been shown to have adverse impacts on forests, freshwaters and soils, killing insect and aquatic life-forms as well as causing damage to buildings and having impacts on human health.Both the lower p H and higher aluminium concentrations in surface water that occur as a result of acid rain can cause damage to fish and other aquatic animals.
