Bucheon's air quality reflects the flat Gyeonggi-do western Seoul metropolitan corridor adjacent to Incheon, with vehicle traffic on surrounding expressways and the manufacturing, logistics, and residential corridor contributing local sources. Seasonal Chinese dust transport elevates PM10 during spring yellow dust episodes, while the regional Northeast Asian industrial background and the broader Seoul metropolitan readings influence the area and Bucheon generally maintains moderate to elevated Seoul western metropolitan suburban readings throughout the year.
