Explanation:

Gasoline is a product of petroleum refining that varies in composition and often includes additives such as antiknock agents, antioxidants, lubricants, and detergents. Tetraethyl lead was one of these additives, and use of leaded gasoline as fuel was responsible for much of the human body burden of this metal for a number of years. However, the phase out of lead from gasoline during the past three decades (in the United States and Europe) has led to an over 90% reduction in human blood lead levels. More recently, other additives such as methylcyclopentadienyl manganese tricarbonyl and methyl t-butyl ether have been foci of concern because of possible adverse environmental impacts of these compounds.
