Abstract

This study focused on assessing seasonal variations and fuel type effects on sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) concentrations around the Qom Combined Cycle Power Plant in Iran from December 2014 to May 2015, using passive sampling at three monitoring stations. Results indicated higher NOₓ and SO₂ levels in winter, particularly when the plant used gasoil instead of natural gas, with NOₓ posing a significant noncarcinogenic health risk to infants and children as hazard quotients exceeded 1. Sobol' sensitivity analysis identified inhalation rate and NOₓ concentration as the most influential factors in health risk variability, highlighting infants as the most vulnerable group. The study concludes that switching to cleaner fuels and implementing emission control technologies are critical to reducing pollutant emissions and associated health risks in the region.
