Air quality in Huocheng right now
Right now the modelled US Air Quality Index for Huocheng, Xinjiang, China is 101, which falls in the "Unhealthy for Sensitive Groups" band (up to 150). People with heart or lung disease, older adults, children and teens should cut back on prolonged or heavy exertion outdoors.
The index is driven mainly by PM10, whose own sub-index is 101. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.
PM2.5 is 31 µg/m³, 2.1 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 155 µg/m³ against a guideline of 45; ozone is 69 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 4.8 µg/m³ (below the 24-hour guideline of 25).
Also this hour: desert dust at 184 µg/m³, high enough to haze the sky, carbon monoxide 487 µg/m³.

Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Huocheng, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.
Wildfire smoke
PM2.5 is forecast to reach 45 µg/m³ in the next 24 hours while NASA satellites detected 29 fire hotspots within 300 km in the last day (nearest about 25 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
Advice for sensitive groups
At 101, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
What the US AQI numbers mean
| US AQI | Category | What it means |
|---|---|---|
| 0-50 | Good | Air quality is satisfactory and poses little or no risk; a good time for outdoor activity. |
| 51-100 | Moderate | Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors. |
| 101-150 | Unhealthy for Sensitive Groups | People with heart or lung disease, older adults, children and teens should cut back on prolonged or heavy exertion outdoors. |
| 151-200 | Unhealthy | Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it and keep windows closed. |
| 201-300 | Very Unhealthy | Health alert: everyone should avoid prolonged or heavy exertion outdoors, and sensitive groups should stay indoors. |
