Centrum pro životní prostředí a zdraví oznámilo, že se bude konat další měření ultra-jemných prachových částic experty z Dánské ekologické rady. Opět to ale vypadá, že se bude měřit pouze v Brně a Praze, městech, jejichž úroveň znečištění ovzduší prachovými částicemi je výrazně nižší, než v Ostravě. Zaslal jsem proto Dánské ekologické radě následující email:

Dear Kåre Press-Kristensen,
I’ve noticed that measurements of ultra-fine particles are coming back to the Czech Republic. I take big interest in air pollution in the Czech Republic, so I welcome every activity that helps understand this important and complex topic. I’m happy to see that air quality in the Czech Republic is going to be analyzed with modern equipment again.
It seems that the analyzed areas are going to be Prague and Brno again. Is there any reason for excluding Ostrava?
Ostrava is hit by particulate air pollution much worse than Brno and Prague, it is a region with more citizens than Brno and fine particles constitute the major part of the total particulate matter mass.
Here are PM2.5 annual average levels from 2013:
Praha 2 Legerova: 26.1
Praha 2 Riegrovy sady: 16.9
Brno – Svatoplukova: 29.7
Brno – Zvonařka: 28.0
Ostrava – Radvanice: 43.9
Ostrava – Přívoz: 34.3
Ostrava – Zábřeh: 33.9
Petrovice u Karviné (Ostrava region): 38.1
Věřňovice (Ostrava region): 35.8
As you can see, Ostrava is a region that is hit by particulate air pollution much worse than Brno and Prague.
Ostrava is the third biggest city in the Czech Republic, and if you include the surrounding regions that are affected by the same type of air pollution (Karviná, Frýdek-Místek, Opava), we’re talking about 1 million citizens living in these bad air quality conditions – more than in Brno, same as in Prague.
Recent study by the Academy of Sciences and other institutions revealed that particles in the range up to 1,15 micrometers constitute more than 70% of the total particulate air pollution in Ostrava.
Thank you for your interest in analyzing the air pollution in the Czech Republic. It would be really great if Ostrava got some coverage in your measurements too.
Odpověď / Response:
… Air pollution in Ostrava is – according to official statistics – mainly from industry – and since we only have EU money for traffic measurements it is only possible to measure (air pollution) from traffic. However, we are very interested in industrial pollution as well – and I’m interesting in visiting Ostrava – we will try to raise money for even more measurements and not only from traffic – then we will be happy to visit you and try to support (air pollution) reductions in Ostrava.
