Annual air pollution limit breached in five days in London
Brixton Road in London breached the city's annual air pollution limit for 2017 in just five days, with levels nearly double the permissible limit. By law, hourly levels of toxic NO2 must not exceed 200 micrograms per cubic metre more than 18 times in the whole year. Notably, NO2 pollution causes 5,900 early deaths every year in London.
