Abstract
When lead antiknocks are restricted, refiners generally increase the aromatic content of motor gasolines to recover the lost octane numbers. This paper includes curves developed to show the relationship between aromatic content and lead content for leaded regular fuels in the United States and leaded regular and premium fuels in Europe. These curves show that lowering the lead content from 0.4 to 0.15 g Pb/litre increases aromatic content by about 20% in U.S. gasolines and over 30% in European gasolines. This paper also summarizes the scientific literature on the effect of increased gasoline aromatics on emissions of polynuclear aromatic hydrocarbons and other aromatic pollutants from vehicles. Lowering the lead content from 0.4 to 0.15 g Pb/litre in European gasolines would increase benzo(a)pyrene emissions by about 25%.
