Lead prices began to rise in early 2007 due to increased worldwide demand. Prices were about $1,200 per tonne of lead in the July, then rose to $2,220 per tonne by September and collapsed back down to $1,200 per tonne in the October of that year.

The current formulation of 100LL (low lead, blue) aviation gasoline contains 2.12 grams per US gallon (0.56 g/L) of TEL, half the amount of the previous 100/130 (green) octane avgas (at 4.24 grams per gallon), [85] and twice as much as the 1 gram per gallon permitted in regular automotive leaded gasoline prior to 1988 and substantially greater ...
According to the Metal Stocks in Society report of 2010, the total amount of lead in use, stockpiled, discarded, or dissipated into the environment, on a global basis, is 8 kg per capita. Much of this is in more developed countries (20–150 kg per capita) rather than less developed ones (1–4 kg per capita). [198]

Avgas is less volatile, with a Reid vapor pressure range of 5.5 to 7 psi, than automotive gasoline, with a range of 8 to 14 psi.
