Air pollution leads to water pollution in the following listed ways:-
i.) Major pollutants in the air are Carbon, nitrogen and sulfur oxides.
ii.) These oxides Dissolve with the rain water during precipitation.
iii.) Mixing of these oxides leads to the formation of Acids like nitric acid, sulphuric acid, carbonic acid..etc.
iv.) These acids mix with pure water of the river and goes deep inside soil to mix with ground water and hence lead to water pollution.
v.) Polluted air also contains mercury as a major pollutant. This mercury is dissolved into the water during rain. Bacteria in water transform it into harmful methyl mercury which makes survival of aquatic life difficult.
