The report discusses research which shows that the quantity of the pollutant emitted or the intensity of the photochemical effect observed with solar irradiation is related to an increase in fuel aromatic content on a per vehicle basis. These estimates do not include the compensation in effects of fuel aromatic increases resulting from the decrease in overall emissions reported to occur from substitution of unleaded deposits from lead-free fuel usage for the present lead deposits. This unleaded deposit effect has been found in most studies to reduce gaseous emissions and polynuclear aromatic hydrocarbon emissions. The cause of this deposit effect has not been isolated with respect to lead, phosphorus and base fuel characteristics.
