In the UK alone, air pollution contributes to tens of thousands of early deaths every year. The European Study of Cohorts for Air Pollution Effects (ESCAPE) aimed to improve the understanding of how air pollution affects health by combining data from across Europe.

Why was this work needed?

There is increasing evidence that air pollution has a harmful effect on people’s health, increasing the risk of some cancers, heart disease, stroke and diseases of the airways, like asthma. However, the discovery of these links is relatively new and there is a need for large studies to determine the severity of these risks.

What happened?

ESCAPE was a collaboration between more than 30 European population studies. The project estimated the exposure to a variety of air pollutants for people living in different places in Europe, including the UK. The study then compared these exposure levels with information like cancer incidence in those places.

What were the benefits?

One of the most important findings from ESCAPE was the discovery that even when air pollution levels comply with the limits currently set in Europe, there can still be significant negative impacts on health. This provides clear evidence to governments and campaigners of the importance of lowering pollution limits and improving air quality.

What type of data was involved?

ESCAPE used a range of techniques to measure air pollution, combining this with the clinical data being collected from cohort study participants. The health data they collected includes information on pregnancy outcomes, rates of heart disease, cancers, asthma and allergies, specific disease biomarkers, causes of death and death rates.

ESCAPE consisted of pre-existing cohort studies where participants have consented to take part.

Who funded and collaborated on this project?

ESCAPE was funded under the European Union's Seventh Framework Programme Theme.
