Study Links London's Ulez to Better Child Lung Health
A study looked at London's ultra-low emission zone called Ulez. Ulez blocks the most polluting vehicles from entering London.
Researchers found Ulez was linked to better lung health in children. They examined 1,600 schoolchildren aged six to nine in London.
Researchers compared them with a similar group from Luton in England. Doctors examined the children before and after Ulez started.
They found lung capacity that pollution had reduced was restored. This restoration happened after Ulez restricted heavily polluting vehicles.
The findings suggest fewer vehicle emissions can improve children's breathing. But researchers say this shows a link not a proven cause.
Klear Note — Lung function describes how well lungs move air during breathing. Luton provided a matched comparison group outside London's Ulez area.
