Most polluted cities in Texas, United States, January 2023
29 cities in Texas, United States ranked by their average PM2.5 over the 31 days. Worst: Port Isabel at 13.7 µg/m³, #285 of 1,225 cities in the world. Cleanest: Lubbock at 3.1. A city needs measurements on 70% of the days to be ranked.
OpenAQ's archive, where our readings come from, has almost none for 7 of these 31 days. Cities in the United States and Europe have them from the EPA's and the European Environment Agency's own records of the same monitors; elsewhere a city's average is over its other days. Why.
Ranked by unhealthy days: the share of each city's measured days with a daily mean over 35.4 µg/m³ (US AQI 101+), Unhealthy for Sensitive Groups or worse on the US EPA's scale. Ties go to the higher average.
