However, leaded gasoline continues to be used in aeronautic, auto racing, and off-road applications. [40] 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.
[6] [122] The announcement was slightly premature, as a few countries still had leaded gasoline for sale as of 2017. [40] On 30 August 2021 the United Nations Environment Programme announced that leaded gasoline had been eliminated. The final stocks of the product were used up in Algeria, which had continued to produce leaded gasoline until ...

A growing number of countries have drawn up plans to ban leaded gasoline in the near future. Some experts speculate that leaded petrol was behind a global crime wave in the ...
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?

A new study connects lead’s past use in gasoline to an increase in mental health disorders among Americans.
Leaded avgas is currently available in several grades with differing maximum lead concentrations. (Unleaded avgas is also available.) Because tetraethyllead is a toxic additive, the minimum amount needed to bring the fuel to the required octane rating is used; actual concentrations are often lower than the permissible maximum.
But while it was banned as a gasoline additive in 1996, the Environmental Protection Agency points out lead is still everywhere: in paint that covers children’s toys, in some dishes and glasses ...
