Why it ranks here

Seasonal. Over the past year its worst months were May, averaging up to 209.0 µg/m³ against 10.5 in its cleanest month. Seasonal peaks usually come from heating, crop burning, fire or dust seasons.

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