Air quality today

The air quality in Lota today is classified as Moderate. The primary pollutant identified is PM2.5 (fine particles). Measurements show a PM2.5 reference value of 14.0 and a PM10 reference value of 16.0, based on six valid observations reported through OpenAQ.

These values reflect the current assessment for the city without additional context or interpretation. This page is informational; for health guidance, use official sources such as EPA AirNow or WHO.

What the data includes

The Lota air‑quality feed contains six measured pollutants – carbon monoxide (CO), nitrogen dioxide (NO₂), ozone (O₃), particulate matter ≤ 10 µm (PM₁₀), particulate matter ≤ 2.5 µm (PM₂.₅) and sulphur dioxide (SO₂). Data come from 12 rows recorded at two monitoring sites, all identified as “Lota rural”. The timestamps show a clear split in freshness: the three gases CO, NO₂ and O₃ were last updated on 2021‑08‑20 21:00 UTC, while the particulate matter and SO₂ values are current to 2026‑02‑10 13:00 UTC. This means that for half of the pollutants the most recent information is more than two years old, whereas the other half reflects conditions measured within the last few days.

Across the older gas measurements the observed range is wide. CO varies from a minimum of 4 583.78 µg/m³ to a maximum of 4 716.58 µg/m³, with a median near 4 650 µg/m³; NO₂ spans 15.68‑83.15 µg/m³ (median ≈ 49.42 µg/m³); O₃ is between 0.19 and 2.78 µg/m³ (median ≈ 1.48 µg/m³). In contrast, the newer particulate data are tightly clustered: PM₁₀ ranges only from 15.0 to 16.0 µg/m³ (median = 15.5 µg/m³) and PM₂.₅ is a single value of 14.0 µg/m³, while SO₂ shows a modest spread of 10.42‑12.0 µg/m³ (median ≈ 11.21 µg/m³). The limited number of stations and the age of many rows indicate that the dataset does not capture spatial or temporal variability uniformly across all pollutants; conditions in Lota can therefore differ by location and time beyond what is reflected in these snapshots.

Data notes

The data shown for Lota reflects six valid measurements and is Updated within 3 days, with the most recent reading recorded at 2026‑02‑10T13:00:00+00:00. This snapshot provides a current view of air quality across the city, but conditions can differ by specific location and time of day, so values may vary locally even though the overall dataset is recent and reliable.
