Analysis of Reduction Strategies for Air Pollutants Discharged from Emission Sources and their Impact on the Seoul Metropolitan Area

The Korean government enacted the "Special Law for Improving Air Quality of Metropolitan Area" in 2003. According to this plan, Korean government plan to lower the concentrations of $PM_{10}$ and $NO_x$ to $40{\mu}g/m^3$ and 22 ppb, respectively, by 2014. In this study, we analyze emission reduction strategies to lower their concentration. Emission reduction for the supply of mass energy and regenerative energy are compared with several scenarios. According to the results, 713 t/y of $NO_x$ and 165 t/y of $PM_{10}$ will be reduced by enhancing the number of households supplied by local heating and air conditioning. And also 5 t/y of $PM_{10}$ and 312 t/y of $NO_x$ will be reduced by replacing conventional energy with solar energy by 2014.
