ISS Previous Year Paper 2020 GS Solution Question

Q.2(b) Discuss the major sources of ambient air pollution in India and examine its impact on human health.

Answer :

Ambient air pollution refers to the contamination of outdoor air by harmful substances such as particulate matter, gases, and toxic chemicals. India faces serious air pollution problems, especially in urban and industrial regions.

Major Sources of Air Pollution

Vehicular Emissions

• Automobiles release pollutants such as carbon monoxide, nitrogen oxides, and particulate matter.

• Rapid growth in vehicle ownership has significantly increased urban air pollution.

Industrial Activities

• Factories, refineries, and manufacturing units emit sulfur dioxide, nitrogen oxides, and other pollutants.

• Thermal power plants are major contributors to air pollution.

  
  

Construction and Road Dust

• Construction activities and poorly maintained roads generate large quantities of particulate matter.

  
  

Crop Residue Burning

• Burning of agricultural residues contributes to seasonal spikes in pollution levels, particularly in northern India.

  
  

Domestic Fuel Burning

• Use of biomass, coal, and traditional cooking fuels releases harmful smoke and pollutants.

• 
  

Impact on Human Health

Air pollution has serious consequences for public health:

• Increased incidence of respiratory diseases such as asthma, bronchitis, and chronic obstructive pulmonary disease (COPD).

• Higher risk of cardiovascular diseases and stroke.

• Adverse effects on children's lung development.

• Increased vulnerability among elderly people and individuals with pre-existing health conditions.

• Premature deaths associated with long-term exposure to polluted air.

  
  

Air pollution also affects productivity, increases healthcare costs, and reduces overall quality of life.

Conclusion

Ambient air pollution is a major environmental and public health challenge in India. Effective pollution control measures, cleaner technologies, sustainable transportation, and greater public awareness are essential for improving air quality and protecting human health.
