0-50 is good, 50-100 is moderate, 100-150 is unhealthy for sensitive groups, 150-200 is unhealthy for all.

  3. There’s about a km of road for each and every one of us

  7. Farmers are plowing and feeding their fields. Remember the protests for nitrogen emissions and all that crap? And our government was like “no we want to protect nature”.

    Well, here you have it. 

  8. Have you looked outside? A lot of fog, this means that there is hardly any wind for the bad air to be filtered out

  11. Looking at VMM maps (https://www.vmm.be/lucht/actuele-luchtkwaliteit) it is mostly PM. Low wind conditions today of course don’t help. Likely sources would be agricultural activity, and maybe some salt spray as we have wind coming from the west. (Since it also seems to be mostly locates in West & East Flanders.)

  12. too many cars outside of Limburg. In Limburs it’s fine since most people take the bus

  13. It’s probably dust and the fact that there is virtually no wind

  15. Funny how just about every comment is different.

    We have no clue.

  16. Belgium is the only country in EU that provides accurate air quality in comparison to the rest of europe might be green numbers but thats because they are cheating the results source; i once read about it

  17. Temperature inversion, the fog being a give away for it.

    Basically warmer air in the sky above cooler air acts like a blanket which prevents vertical movement of air. This means ppm of a lot of pollution will be higher.

    Isnt this thought in high schools anymore?

  21. Belgium is one of the most crowded area in Europe. Many cars, many old cars, the norms for pollution are less implemented so…

    You know who is suffering most? people with respiratory issues: children, asthmatic people…

  22. Tom van Grieken zal dit oplossen door allochtone trouwstoeten harder aan te pakken.

  23. I saw that OP posted a map without much information what it says. I checked instead [the PM2.5 map on Windy](https://www.windy.com/-PM2-5-pm2p5?camsEu,pm2p5,51.176,6.240,7) and indeed, PM2.5 pollution is still pretty bad at the moment.

    ON first glance it seems like the wind is currently just moving the bad air around over the Belgian coast, rather than dispersing it, and that causes the buildup.

    NO2 concentrations look even worse: [https://www.windy.com/-Menu/menu?camsEu,no2,50.180,2.977,7](https://www.windy.com/-Menu/menu?camsEu,no2,50.180,2.977,7)

    And here’s SO2 for you: [https://www.windy.com/-Menu/menu?tcso2,53.475,-2.505,5](https://www.windy.com/-Menu/menu?tcso2,53.475,-2.505,5)

    My advice for today: don’t breathe!
