  • Air Pollution

    Secondary Pollutants

    Why in the News?

    A recent analysis by the Centre for Research on Energy and Clean Air has revealed that secondary pollutants now contribute nearly one third of Delhi’s annual PM2.5 load, highlighting a major shift in the nature of urban air pollution.

    What are Secondary Pollutants?

    • Secondary pollutants are not emitted directly from pollution sources.
    • They are formed in the atmosphere when primary pollutants such as SO₂, NOx and VOCs undergo chemical reactions.
    • These reactions are influenced by sunlight, temperature, humidity and stagnant air conditions.
    • They often accumulate downwind and over time, making monitoring and control more complex than primary pollutants.

    Major Secondary Pollutants

    • Secondary PM2.5: Ammonium sulfate and Ammonium nitrate
    • Ozone (O₃): Formed from nitrogen oxides (NOx) and volatile organic compounds (VOCs) in the presence of sunlight
    • Acids: Sulfuric acid and Nitric acid (contributors to acid rain)
    • Photochemical smog components: Peroxyacetyl nitrates (PANs) and Nitrogen dioxide (NO₂)

    Implications

    Regional and transboundary impact

    • Secondary aerosols can travel hundreds of kilometres
    • Delhi’s air quality is influenced by emissions from coal intensive states beyond the NCR

    Winter smog intensification

    • Moist and stagnant winter air sharply increases secondary PM2.5

    Health risks

    • Fine secondary particles penetrate deep into the lungs
    • Increase risks of respiratory and cardiovascular diseases

    Prelims Pointers

    • Secondary pollutants are formed in the atmosphere, not emitted directly
    • Ammonia plays a key role in secondary PM2.5 formation
    • Winter meteorology is crucial for secondary aerosol build up
    • Air pollution control requires regional coordination, not only city level measures
    [2013] Photochemical smog is a resultant of the reaction among 

    (a) NO₂, O₃ and peroxyacetyl nitrate in the presence of sunlight

    (b) CO₂, O₂, and peroxyacetyl nitrate in the presence of sunlight

    (c) CO, CO₂, and NO₂ at low temperature

    (d) high concentration of NO₂, O₃ and CO in the evening
