Neighbourhoods of Łódź with the cleanest air
Annual mean PM2.5 across the neighbourhoods of Łódź, in micrograms per cubic metre. An annual mean, not a daily one — a single smoggy week does not move a neighbourhood.
Two limits, not one
The WHO recommends an annual mean below 5 µg/m³. The EU's legal limit is five times looser at 25 µg/m³. A neighbourhood can therefore comply with the law and still exceed the health guideline, which is why both are given.
Above the WHO guideline (5 µg/m³): 5 of 5 measured neighbourhoods. Above the EU limit (25 µg/m³): 0.
From 16.0 µg/m³ in Łódź-Bałuty to 17.7 µg/m³ in Łódź-Śródmieście — a 1.7 µg/m³ range.
