RIVM Report 2015-0086
Concentrations of particulate matter (PM10) and nitrogen dioxide (NO2) on the two permanent measurement locations in Hilversum and Laren are within legal limits, as in previous years. These measurement locations are representative for locations exposed to traffic and locations in the city background in the Hilversum region, respectively. In 2013, daily averaged concentrations of particulate matter on the two stations did not differ significantly. They were also comparable to those on other stations of the Dutch Air Quality Monitoring Network (LML) in a city environment. Concentrations of nitrogen oxides vary substantially during the day. The highest values were recorded during the morning rush hour on locations with heavy traffic. Annual averaged levels of nitrogen (di)oxides on the stations in Hilversum are a little lower than those at similar stations of LML elsewhere. For the years 2009-2013 the Hilversum stations show a downward trend in the concentration levels of PM10 and NO2. This trend follows the general trend in the Netherlands at similar LML stations. However, the annual averaged concentration levels in Hilversum are lower than the national average of similar type stations in the LML. The results above summarize the air quality measurements by RIVM. This research is performed under contract from the city of Hilversum, to provide air quality data for the Integral Accessibility Plan (IBP) for Hilversum. The IBP aims to improve traffic streams in and around Hilversum.
