Air quality in Novi Sad right now
Right now the modelled US Air Quality Index for Novi Sad, Vojvodina, Serbia is 63, 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 63. 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 28 µg/m³, 1.9 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 37 µg/m³ against a guideline of 45; ozone is 30 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 20 µg/m³ (below the 24-hour guideline of 25).
Also this hour: sulphur dioxide at 92 µg/m³, carbon monoxide 235 µg/m³.
NASA FIRMS shows 23 fire hotspots within 300 km in the last day (nearest about 37 km), but particle levels are not elevated enough to point to smoke right now.
