Air pollution level warning-Wednesday 2 April

High levels of air pollution which have been affecting parts of England today (2 April) are set to get worse and spread, DEFRA warns.

Defra has a 10-point scale for measuring air quality - with 1 meaning there is a "low" risk of air pollution and 10 warning of "very high" levels. Readings for Wednesday are expected to reach 8 or 9 in much of southern England, East Anglia and the Midlands, and possibly 10 along England's southern coast.

Advice on the department's website states that for high levels of pollution:

Adults and children with lung problems, and adults with heart problems, should reduce strenuous physical exertion, particularly outdoors, and particularly if they experience symptoms. People with asthma may find they need to use their reliever inhaler more often. Older people should also reduce physical exertion."

Below is the recommended actions and health advice from the Defra website:
