write causes and effects of air pollution


  • Combustion of fuel is one of the major causes of air pollution in urban areas. Burning of fossil fuels such as natural gas and gasoline leads to the emission of carbon dioxide and other gases, which deteriorate the quality of air, making it polluted.
  • Increased level of carbon dioxide in the atmosphere is one of the prime causes of air pollution. Power plants, exhaust fumes of automobiles, airplanes and other human activities involving the burning of gasoline and natural gas are related to the emission of this greenhouse gas.
  • The chlorofluorocarbons (CFCs), a class of synthetic chemicals used in refrigerants and aerosol propellants, have caused hole in Earth's ozone layer. The use of this banned chemicals is related with the increasing levels of air pollution.
  • Sulfur dioxide is one of the components of smog, which is related with contamination of the Earth's atmosphere. This synthetic chemical is the prime cause of acid rain.
  • Air pollution is partially caused by the particulates formed by a variety of substances, such as dust, pollen and other organic materials.
  • Increased road and air traffic is another reason related to the high level of air pollution. 
Health Effects of Air Pollution 
  • Asthma is a chronic disease common among children and adults. The shortness of breath, a prime symptom of this disease, can be triggered by pollutants present in the air, such as smog.
  • Lung infections can occur when polluted air is inhaled. This can also lead to shortness of breath.
  • Air pollution may influence the development of Chronic Obstructive Pulmonary Disease (COPD).
  • Air pollution can also lead to lung cancer.
  • Air pollution can result in blockage in the coronary artery or blood vessels that supply blood to the heart. This condition is diagnosed as Coronary Artery Disease.
  • High level of pollution in the air can also lead to heart failure. Irregular or abnormal rhythms of heartbeat are often cited as health problems related to air pollution.
