Scientists ‘Stunned’ by Children’s Lung Recovery in Ultra Low Emission Zone
Smitha Mundasad, Health reporter, BBC
Children had lung function tests every year.
Researchers found that children in London whose lung growth had been stunted by pollution showed impressive improvements after the introduction of an Ultra Low Emission Zone (Ulez) in 2019 reduced emissions.
Key Findings:
- The study followed over 3,400 primary school children in London and Luton.
- Researchers compared lung growth in children living within the Ulez to children in Luton, a less polluted area.
- Children in the Ulez area saw a significant acceleration in lung growth over four years, reaching similar levels to their peers in Luton.
Experts’ Reactions:
- Prof. Chris Griffiths, a senior author on the study, expressed surprise and admiration for the rapid recovery: "I was absolutely stunned when I first saw the results… This shows an ambitious clean air zone can drive pollution levels down, rapidly restoring children’s stunted lung growth."
Context:
Air pollution can stunt the growth of young children’s lungs, increasing their risk of asthma, heart disease, diabetes, and even premature death. Children are particularly vulnerable due to their developing lungs and immune systems.
Other Considerations:
While the study provides strong evidence for the benefits of clean air zones, independent researchers caution that other factors must also be considered.
