Indoor Air Pollution क्या है?
ऐतिहासिक पृष्ठभूमि
मुख्य प्रावधान
5 points- 1.
Sources: Biomass combustion (wood, dung, crop residue), tobacco smoke, building materials (asbestos, formaldehyde, radon), household products (cleaners, aerosols), pesticides, and outdoor air infiltration.
- 2.
Pollutants: Key pollutants include Particulate Matter (PM2.5, PM10), Volatile Organic Compounds (VOCs), Carbon Monoxide (CO), Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Ozone (O3), and biological contaminants (mold, bacteria, viruses).
- 3.
Health Impacts: Leads to respiratory diseases (asthma, COPD), cardiovascular diseases, cancers, neurological effects, and eye/skin irritation. Children, the elderly, and individuals with pre-existing conditions are particularly vulnerable.
- 4.
Mitigation Strategies: Include improving ventilation (natural or mechanical), source control (reducing pollutant emissions), air purification (using HEPA filters and activated carbon), regular cleaning, and monitoring indoor air quality.
- 5.
Global Burden: The World Health Organization (WHO) estimates millions of premature deaths annually due to household air pollution, primarily from inefficient cooking fuels.

Key Statistics: Indoor Air Pollution & Mitigation
Highlights critical statistics related to indoor air pollution and the impact of mitigation efforts like PMUY, providing quantitative context for UPSC answers.
- Indoor vs. Outdoor Pollution
- 2-5x Higher
- Global Premature Deaths (Household Air Pollution)
- ~3.2 Million Annually
- PMUY LPG Coverage (India)
- >99% Households
Indoor air pollution concentrations are significantly higher than outdoor levels, posing a greater immediate threat in enclosed spaces.
According to WHO, household air pollution (primarily from cooking fuels) causes millions of premature deaths globally each year.
Pradhan Mantri Ujjwala Yojana (PMUY) has significantly increased LPG penetration, reducing reliance on traditional biomass fuels and improving indoor air quality.
