Tóm tắt

 Lahore (31.320°N
  74.220°E), Pakistan's second-largest city with a population of 13 million, is considered among the most polluted cities in the world and the most polluted city in Pakistan. We estimated emissions from one of the major sources (brick kilns) and analysed the corresponding impacts on regional air quality. The distribution of pollutants from the brick kilns in Lahore was calculated via a steady-state model (Sutton's model) and a dynamic model (Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model version 4). Sutton's model was used to determine the dispersion of a hypothetical pollutant in the vicinity of multiple brick kilns in a steady state. HYSPLIT was employed to compute the dynamic distribution of pollutant concentrations (24 h) for six pollutants using meteorological data (GDAS) and published emission rates of pollutants. The results for November-February 2021-2022 indicated that only SO
