Why it ranks here

Likely fire smoke. On Sep 29, when Obrenovac averaged 28.3 µg/m³ (its typical day: 13.6), NASA satellites detected 154 fires within 300 km (103 within 100 km). Smoke from those fires is a likely contributor; we don't check which way the wind blew, and mapped smoke can be high above the ground.

Based on Obrenovac's own measurements, with fire detections from NASA FIRMS and smoke maps from NOAA HMS; causes are the usual kinds for a pattern like this, not a confirmed source.
