We have estimated risks from an vehicles, diesel vehicles, and city bus emissions using several assumption and exposure scenarios and also risk benefit resulted in replacing diesel bus to CNG bus. As results, health risks due to dies디 emissions were much higher than others. PM10 was the most important pollutant of vehicle emissions in theoretical mortality incidence, and PM10 and nitrogen dioxide did so in respiratory hospital admission. Risk. benefits from CNG bus were about 90% and higher until 2007 in condition that diesel city buses have been not increased any more since 2000. Many uncertainties should be considered in those estimates.
