Major contributors to acid rain are SO2 and NO2.
What is acid rain?
Acid rain is said to be the precipitation of acid in the form of rain in the simplest manner. When atmospheric pollutants like oxides of nitrogen and sulphur react with rainwater and come down with the rain, then this results in Acid Rain.
Effect of acid rain
The effect of acid rain is given below.
- Acid rain has the greatest ecological impact in aquatic ecosystems such as streams, wetlands, and marshes, where fish and other wildlife can be harmful.
- As acidic rainwater runs via the soil and then floods into streams and lakes, it can leach aluminium from soil clay particles.
- Acid rain has been shown to have negative effects on plants, freshwaters, and soils, as well as destroying insects and aquatic life-forms, peeling paint, deterioration of steel structures such as bridges, and weathering of stone buildings and sculptures, as well as having negative effects on human health.
