He noticed that the air in the cities contained many different contaminates including sulfuric acid, which he believed to be the cause of corroding metals and certain types of damage to plants. His colleagues ignored his studies and findings and it wasn’t until 100 years later that scientists started to explore this serious problem.There are many different pollutants that incur the effects of acid deposition. Primary pollutants are emitted directly into the atmosphere from sources such as power plants, automobiles, factories, and even residential furnaces. These primary pollutants include sulfur dioxide (SO2) and nitrogen oxide (NO). When nitrogen and sulfur combine with oxygen, a very reactive element in our atmosphere, secondary pollutants are formed. These include photochemical oxidants, such as ozone, and acid deposition. Acid rain forms when nitrogen oxides and sulfur dioxide react with oxidants and moisture in
