A truck carries leaded fuel around DuPage Airport. Research shows that even tiny amounts of lead in young children can trigger learning disabilities, aggression and criminal behaviour later in life.

Aviation is the last major source of toxic lead in the United States.

LEADED petrol is such a well-known scourge that automobile fuel made with the brain-damaging additive is still sold in only six countries: Afghanistan, Algeria, Iraq, Myanmar, North Korea and Yemen.
