The Contribution of City Buses to Urban Air Pollution in Jerusalem, Israel

Abstract

A survey of the contribution of city buses to the total emission of gaseous and particulate pollutants was conducted in the city of Jerusalem, Israel. The results reveal that buses are one of the main sources for nitrogen oxides, and, to a lesser extent, particulate matter. Contribution of buses to carbon monoxide and hydrocarbon levels was insignificant as compared to gasoline powered private cars. Possible vehicular restrictions in downtown districts are examined.
