Air quality in Mantampay right now
Right now the modelled US Air Quality Index for Mantampay, Northern Mindanao, Philippines is 51, 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 51. 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 5 µg/m³, within the WHO 24-hour guideline of 15 µg/m³; PM10 is 5.1 µg/m³ against a guideline of 45; ozone is 37 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 5.4 µg/m³ (below the 24-hour guideline of 25).
Also this hour: carbon monoxide 381 µg/m³.
NASA FIRMS shows 8 fire hotspots within 300 km in the last day (nearest about 101 km), but particle levels are not elevated enough to point to smoke right now.
