Since 2011, leaded gasoline has been banned in every country. A 2011 study backed by the United Nations estimated that the removal of TEL had resulted in $2.4 trillion in annual benefits, and 1.2 million fewer premature deaths. [6] Despite being banned from use in automotive fuel, TEL is sometimes still used in certain grades of aviation fuel.
Piston-engine aircraft remain the single largest source of highly toxic airborne lead. Leaded gas was phased out 25 years ago. Why are these planes still using toxic fuel?
Gasoline, as delivered at the pump, also contains additives to reduce internal engine carbon buildups, improve combustion, and to allow easier starting in cold climates. In some parts of South America, Asia, and the Middle East, leaded gasoline is still in use. Leaded gasoline was phased out in sub-Saharan Africa, starting 1 January 2006. A ...

However, leaded gasoline continues to be used in aeronautic, auto racing, and off-road applications. [38] The use of leaded additives is still permitted worldwide for the formulation of some grades of aviation gasoline such as 100LL, because the required octane rating is difficult to reach without the use of leaded additives.
Of that group, the greatest lead-linked mental illness burden was for Generation Xers born between 1966 and 1970, coinciding with peak use of leaded gasoline in the mid-1960s and mid-1970s.
Unlike motor gasoline, which has been formulated without lead since the 1970s to allow the use of catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyl lead, a toxic lead-containing additive used to aid in lubrication of the engine, increase octane rating, and prevent engine knocking ...
A new study connects lead’s past use in gasoline to an increase in mental health disorders among Americans.
