Air quality in Đức Phổ right now
Right now the modelled US Air Quality Index for Đức Phổ, Quang Ngai, Vietnam is 69, 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 69. 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 23 µg/m³, 1.5 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 26 µg/m³ against a guideline of 45; ozone is 65 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 6 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 473 µg/m³.
NASA FIRMS shows 331 fire hotspots within 300 km in the last day (nearest about 3 km), but particle levels are not elevated enough to point to smoke right now.
