  2. Many industries release high amount of poisonous gases like carbon monoxide (CO) into the atmosphere, causing air pollution.
  3. Forest fires, excessive use of chlorofluorocarbons (CFCs), excessive mining and ore refining release harmful gases into the air leading to air pollution.

Effects of Air Pollution
It affects the respiratory system and causes diseases like asthma, lung cancer, pneumonia, etc.

  • Pollutant gases cause allergies, irritation in eyes, lung, etc.
  • Gases like NO2, SO2, etc., get dissolved in rain to give rise to acid rain.
