Air Quality- Immission Traffic 2020 Fine Dust (PM2.5)

File gives an overview of the air quality of particulate matter (PM2.5) around national, provincial and municipal roads in Gelderland over the year 2020. The data is calculated nationwide using the reporting tool. Per road section it is indicated what the concentration is at 10 meters from the edge of the road. Air quality is represented in five concentration classes. For the annual mean PM2,5 concentration, from 2015 onwards, a limit of 25 µg/m³ applies.In addition, an ‘indicative limit value’ exists for 2020 for the annual average of 20 µg/m³. The World Health Organisation (WHO) recommends 10 µg/m³ as a safe standard according to the latest scientific insights. Air quality is calculated, among other things, by means of traffic sets and calculation models. The sources, such as industry and agriculture, have been incorporated into the background concentration. The total concentration also includes the direct contribution from road traffic. The values calculated with the model have an inaccuracy of 20-25 percent.
