Lead from petrol persists in London's air despite it being banned in 1999, research suggests.

Levels in the capital's atmosphere have dropped drastically since lead additives were phased out and meet current UK air quality targets.

But research by Imperial College London found airborne particles are still highly lead-enriched compared to natural background levels.

Up to 40% comes from the legacy of leaded petrol, the study found.

An interesting thought......

You can lead a horse to water but a pencil must be lead.
