Around 8 p.m., the worst air quality in terms of PM10 dust, defined as unhealthy, prevailed in Zabierzów. The local measurement station showed the concentration of harmful particles in the air at the level of 117 micrograms per cubic meter (µg/m3), which means 195 percent of the daily norm. A similarly difficult situation occurred in Auschwitz, where 115 µg/m3 was recorded, i.e. 192%. daily norm.

In many other towns, especially in the southern part of the country, the air quality was average in terms of PM10 dust content.

When the air quality is good

We talk about good quality air when the concentration of harmful dust does not exceed:

  • in the case of PM10 dust – 60 micrograms per cubic meter (µg/m3);
  • in the case of PM2.5 dust – 36 µg/m3;
  • in the case of benzene – 10 µg/m3.

What is PM10

PM10 is a mixture of particles suspended in the air with a diameter not exceeding 10 micrometers. Its occurrence is related, among other things, to the combustion processes of solid and liquid fuels.

What is PM2.5

PM2.5 is a mixture of particles suspended in the air with a diameter not exceeding 2.5 micrometers. According to the World Health Organization, it is the most harmful atmospheric pollutant to humans. It reaches not only the respiratory system, but also the circulatory system. It stays in our body much longer.

What is benzene

Benzo(a)pyrene is a carcinogenic and mutagenic chemical compound that is a representative of polycyclic aromatic hydrocarbons (PAHs). Benzo(a)pyrene has low acute toxicity and high chronic toxicity, which is related to its ability to accumulate in the body.
