Area of Science:

  • Environmental Science
  • Atmospheric Chemistry
  • Pollution Modeling

Background:

  • Jamshedpur, India's steel city, faces rising air pollution due to industrialization.
  • Nitrogen oxide (NOx) emissions are a major concern from industrial, vehicular, and domestic sources.

Purpose of the Study:

  • To estimate the impact of NOx emissions on air quality in Jamshedpur.
  • To quantify the contribution of different sources to ambient NOx levels.

Main Methods:

  • Utilized the Industrial Source Complex Short-Term (ISCST) Gaussian dispersion model.
  • Compared model-predicted NOx concentrations with measured data for performance evaluation.

Main Results:

  • Industrial activities were the largest contributors to NOx, accounting for 53%.

  • Vehicular and domestic sources contributed 40% and 7% respectively.
  • The dispersion model demonstrated good performance with approximately 68% accuracy.

    • Conclusions:

    • Industrial emissions are the primary driver of NOx pollution in Jamshedpur.
    • The ISCST model is a reliable tool for assessing air quality impacts in industrial regions.
    • Effective pollution control strategies targeting industrial emissions are crucial for Jamshedpur.
