¿Qué significan los tres valores de partículas finas PM₁₀, PM₂,₅ y PM₁?
The PM₁₀ value measures particles up to 10 µm in size; PM₂.₅ measures particles with a diameter of up to 2.5 µm; and PM₁ measures particles up to 1 µm in size. The PM₁₀ value therefore also includes the PM₂.₅ and PM₁ values, and the PM₂.₅ value also includes PM₁. For values measured in µg/m³ or as a particle count, the following applies: PM₁₀ value > PM₂,₅ value > PM₁ value.
