For more information, air quality forecasts, latest measurements and health advice are available on UK-AIR. Updates on current and forecast levels of air pollution can also be found on Twitter (@DefraUKAir). Public Health England advises that some people are more sensitive to pollution than others and may begin to notice an effect on their breathing. People with asthma are not necessarily more sensitive but, if affected, can use their reliever inhaler to alleviate symptoms. If affected, people are urged to take sensible precautions. In particular, avoiding exercise outdoors in the afternoon can reduce individual exposure to ozone.

If the pollution information or alert thresholds are again breached, further alerts will be issued on our UK Air website http://uk-air.defra.gov.uk/.
