Air quality in Huanren right now
Right now the modelled US Air Quality Index for Huanren, Liaoning, China is 52, which falls in the "Moderate" band (up to 100). Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors.
The index is driven mainly by PM2.5, whose own sub-index is 52. 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 14 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 18 µg/m³ against a guideline of 45; ozone is 31 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 8.3 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 199 µg/m³.
NASA FIRMS shows 268 fire hotspots within 300 km in the last day (nearest about 44 km), but particle levels are not elevated enough to point to smoke right now.
