Information about pollution concentrations in the borough set against the health based objectives from the national Air Quality Strategy.
These maps have been compiled using the London Atmospheric Emissions Inventory 2008, which is produced by the Greater London Authority (GLA). The maps show modelled (not actual) concentrations of nitrogen dioxide and PM10.
You will see that the highest concentrations of nitrogen dioxide (NO2) and particulate matter (PM10) are concentrated around busy roads, although for nitrogen dioxide, large areas of the borough exceed the national objective level of 40µg/m3. This is because domestic heating systems (such as boilers) also make a significant contribution to the high levels of nitrogen dioxide, as well as road transport.

This map shows the number of days per year that the daily mean objective level for PM10 is exceeded. The objective level of 50µg/m3 is allowed to be exceeded up to 35 times per year.

The airTEXT service provides free alerts and forecasts for air pollution, UV, pollen and temperature in Greater London. It also provides health advice. The service is particularly useful for people who suffer from illnesses such as: asthma, emphysema, heart disease, bronchitis, chronic obstructive pulmonary disease (COPD) and angina.
