Air quality in Kolpino right now
Right now the modelled US Air Quality Index for Kolpino, St. Petersburg, Russia is 53, 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 53. 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.

Also this hour: carbon monoxide 142 µg/m³.
NASA FIRMS shows 1 fire hotspot within 300 km in the last day (nearest about 289 km), but particle levels are not elevated enough to point to smoke right now.
