Abstract :

Air pollution defined as ”existence ofAir pollution defined as ”existence of unfavourable matters in concentration, duration, and frequencies that can has an adverse effect on human wellbeing and environment”. World health organization (WHO) estimates that annually 500000 persons have unripe death because ofair pollution. Sulphur dioxide is one of the air  pollutant that has acute effects on human health.Fossil fuels consumption in point sources and industrial processes is the main source of sulphur dioxide was emitted to atmosphere. Annuallyaround 547500 tons of sulphur dioxide emitted from thermal power  lants in Iran. In comparison of other industries, thermal power plants are main source of this type of pollutions in Iran. In this study we used AERMOD model (a kind of GAUSSIAN models) to Dispersion modelling of SO2 pollution from Ramin Ahwaz power plant. The results have shown that   ulphur dioxide concentration emitted from this power plant in any  indition of weather is lower than threshold limits specified by Iran DOE and US EPA.
