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.
