Ulez led to better lung size and function among London children, study finds

Researchers find capacity stunted by pollution was restored after introduction of ultra-low emission zone

Examinations of London schoolchildren before and after the introduction of the city's ultra-low emission zone (Ulez) found a restoration of lung capacity that had been stunted by exposure to pollution.
