News from ISGlobal
Researchers from ISGlobal have participated in a study that discards a clear association between socioeconomic level and exposure to air pollution in Europe. The research team, composed by scientists from 25 European institutions, has analysed data from more than 5,700 people in 16 western European cities. The results have been published in the journal Environment International.
To determine the socioeconomic level of the participants in the study, the authors took into account the education level and the occupation at the individual level, as well as the unemployment rate at the neighbourhood-level. The NO2 annual concentration exposure was estimated using data from the ESCAPE project.
The 16 cities analysed are situated in 8 countries of Western Europe. In 14 of them, no significant association was found between estimated socioeconomic level and exposure to air pollution. However, independently of the individual status, the exposure to NO2 was higher for residents of neighbourhoods with the highest unemployment rates in 11 of the 16 cities. Interestingly, in Barcelona and Oviedo the association was inversed, i.e. participants living in areas with high unemployment rates were less exposed to pollution.
