Why it ranks here

Seasonal. Over the past year its worst months were January, averaging up to 28.1 µg/m³ against 8.5 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

Based on Buftea's own measurements; causes are the usual kinds for a pattern like this, not a confirmed source.
