GES map air quality - state 2017
Description
Coverage map of the Health Effects Screening score (GES) of local air quality in Flanders. The indicator is based on the annual average NO2 (nitrogen dioxide) concentrations (Vlaamse Milieumaatschappij 2017), which was modelled with the RIO-IFDM-OSPM model chain. This pollutant was taken as a basis because of its large spatial variation, strong link with local emissions and well-documented health effects. The concentrations of NO2 were then divided into classes using the Dutch methodology Health Effect Screening (GES) that provide an insight into potential health effects of air pollution by NO2, as the first indication for local air quality. Of course, other pollutants (e.g. particulate matter or ozone) are also important in the further analysis and assessment of local air quality. The GES classes were defined in this way: GES 1 = 0-10 μg/m3 annual mean NO2 = "good"; GES 4 = 10-20 μg/m3 annual mean NO2 = "moderate"; GES 6 = 20-30 μg/m3 annual mean NO2= "insufficient", GES 7 = 30-40 μg/m3 annual mean NO2= "extremely insufficient", GES 8 >40 μg/m3 annual mean NO2= "very insufficient". From GES 6, the health advice value as advised by the Agency for Care and Health (maximum 20 μg/m3 annual mean NO2) is exceeded, but lower concentrations also have negative effects on health.
