Solution

Air Pollution
Many Industries are responsible for causing air pollution. Petroleum refineries are a major source of gaseous pollutants like sulphur dioxide and nitrogen dioxide.
These industries are responsible for air pollution as well as water pollution as smoke from these industries goes up in the air and liquid waste is mostly drained into rivers.
Nitrogen dioxide and Sulphur dioxide are harmful to humans if inhaled and if it goes up in the atmosphere can cause acid rain.
Acid rain again can retard the growth of plants and trees and is harmful to humans as well.
