Ambient concentration of benzene in air due to vehicular movement in Mumbai

摘要

An USEPA study on air toxics related to vehicular emission1 establishes benzene in air as a pollutant strictly related to industrial activities and automotive emissions. Efforts to reduce lead content of the fuel gasoline and to maintain the octane number have led to an increase in benzene and other aromatic hydrocarbons in gasoline. An increase in the concentration of these chemicals in the air as a primary pollutant and as precursors of photochemical smog is an obvious result.
