More than 4.5m affected, says UN group, while tests suggest children’s shorter height increases exposure on busy roads

 

More than 4.5 million children in the UK are growing up in areas with toxic levels of air pollution, the UN children’s organisation Unicef has warned.

Tests suggesting that children walking along busy roads are exposed to a third more air pollution than adults, as their shorter height places them close to passing car exhausts, were also released on Thursday.
