Busan's air quality reflects South Korea's southeastern Nakdong River delta and Korea Strait coastal position, with vehicle traffic on surrounding expressways and the major container port, shipbuilding, and manufacturing corridor generating elevated maritime SO₂ and NOₓ. Consistent Korea Strait and East Sea maritime breezes provide ventilation, while the port's extraordinary shipping volume and the regional Northeast Asian industrial background maintain Busan among South Korea's more maritimely influenced major port environments.
