Air quality in Điện Bàn right now
Right now the modelled US Air Quality Index for Điện Bàn, Da Nang City, Vietnam is 64, 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 64. 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 20 µg/m³, 1.3 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 25 µg/m³ against a guideline of 45; ozone is 90 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 12 µg/m³ (below the 24-hour guideline of 25).
Also this hour: UV index 2.5, carbon monoxide 418 µg/m³.
NASA FIRMS shows 77 fire hotspots within 300 km in the last day (nearest about 13 km), but particle levels are not elevated enough to point to smoke right now.
