Long-term effects of air pollution on health

UK-AIR is being replaced with new, easier to use services.

For local air pollution forecasts and health advice, use the Check air quality service.

For information about the Daily Air Quality Index (DAQI) and associated health advice, go to Health effects of air pollution.

To access air pollution datasets, use the Get air pollution data service. The service currently offers a limited amount of data, but we’re adding new data regularly.

Starting in 2026, all the information, data and reports on UK-AIR will be moved to new sites. To find out more or to get involved in research to inform this work, contact aqie.correspondence@defra.gov.uk.
