SmogRank / Poland

Air quality in Chojnów

Lower Silesia, Poland. Measured until 2 Jan 2025; not measured today, so it is only on past boards. We make model estimates only for places of 15,000 people or more.

Its measured days

SmogRank measured Chojnów with ground monitors from EEA from 16 Jan 2024 to 2 Jan 2025: 343 days, averaging 17.7 µg/m³. Its monitors stopped giving readings we can use, so it isn't ranked today, but those days stay on the past boards: 343 day boards.
