Massive-scale focus maps for the Netherlands. 2024 report
Resume
Yearly, the RIVM produces maps of air air pollution within the Netherlands. This occurs for numerous substances within the air, together with nitrogen dioxide and particulate matter. The RIVM makes use of each mannequin calculations and measurements to create these GCN Massive-scale Focus Maps of the Netherlands (Massive-scale Focus Maps of the Netherlands) maps. On this approach, the concentrations finest correspond to the precise state of affairs up to now yr.
The air high quality was higher in 2023 than in 2022. The adjustments are primarily as a result of climate situations. As a result of it rained greater than in previous years, extra air pollution ended up on the bottom with the rain. As well as, the wind was blowing tougher, inflicting the substances to unfold extra by means of the air.
The common concentrations of nitrogen dioxide within the air had been decrease in 2023 (greater than 23 p.c) than in 2022. The common concentrations of particulate matter had been additionally decrease in 2023 than in 2022. The focus of particle dimension PM10 particulate matter (particulate matter) decreased by nearly 13 p.c and that of PM2.5 particulate matter (particulate matter) by nearly 15 p.c.
In every examine we take a look at how assured we’re in our calculations. On this examine there are additionally uncertainties within the calculated concentrations. The uncertainties for the Dutch common are roughly 10 p.c. Which means the calculated worth most definitely doesn’t deviate by greater than 10 p.c from the quantity of drugs within the air. The uncertainties within the concentrations are better at particular places.
Poor air high quality is dangerous to well being. The GCN maps are used to watch the event of air high quality within the Netherlands. Governments use the longer term expectations to make coverage for higher air high quality.
This time, the RIVM didn’t make new maps of the anticipated concentrations for the years as much as and together with 2040. These will any more be made each different yr. This suits in with the Local weather and Vitality Outlook of the Netherlands Environmental Evaluation Company, which describes the anticipated results of Dutch local weather and vitality coverage on air high quality. The maps made final yr in regards to the future are nonetheless legitimate. Since 2023, the RIVM has now not revealed the info on nitrogen deposition (the GDN maps) along with the GCN maps.
