Even small increases in nitrogen dioxide levels in the air may be linked to increases in cardiovascular and respiratory deaths, according to research published by The BMJ today.

The findings suggest a need to revise and tighten the current air quality guidelines, and to consider stricter regulatory limits for nitrogen dioxide concentrations.

Nitrogen dioxide (NO2) is a common air pollutant formed by burning fuel for things like transport, power and industrial processes.
