Daily mean PM2.5 on October 21, 2026 (00:00–24:00 UTC): 4 µg/m³ from 8 sensors that passed the quality check — the same value as in the Atmy Data Hub. No. 14 of 18 cities in Russia and No. 243 of 297 worldwide, from the most polluted.
Right now in Kazan, PM2.5 averages 5.0 µg/m³ — “good” on the US EPA scale (approximate, from hourly readings). Mean of 6 sensors on the Atmy network, readings from 20:37–20:57 local time (17:37–17:57 UTC), summary prepared at 21:00 local time. Median: 3.9 µg/m³; range across sensors: 2.0–12.3 µg/m³.
The current level is “good” (US EPA scale, approximate). Air quality is satisfactory; no restrictions are recommended. This is the standard guidance of the scale, not medical advice.
Highest current reading: 12.3 µg/m³ (SC #78983). Lowest: 2.0 µg/m³ (SC #66893). The list shows every sensor, highest first.
From Atmy sensors and connected public networks (citizen, experimental and government monitors), aggregated by Atmy. Values are approximate; see the methodology.
The summary is rebuilt every 15 minutes from the latest reading of each sensor, each no older than one hour.
Over the last 365 days with data, the mean daily PM2.5 in Kazan was 4.5 µg/m³ — within the WHO annual guideline (5 µg/m³). Over the last 30 days: 4.1 µg/m³. From Atmy's archive of daily city means.
In Atmy's daily archive, the cleanest month of the last year was May 2026: 2.9 µg/m³ on average.
The most polluted month of the last year was March 2026: 8.5 µg/m³ on average.
From November to March the mean daily PM2.5 was 5.2 µg/m³, from June to August 4.0 µg/m³ (last 365 days).
The daily value is the Data Hub’s: the mean of the city’s sensors that passed the nightly quality check, each with at least 12 valid hours, and only with sensors at four places 500 m apart; days are UTC.
“Now” uses the same sensors and rule: the mean of their latest readings, each at most 60 minutes old, shown only with sensors at four places 500 m apart reporting.
