Incheon's air quality reflects South Korea's Yellow Sea coastal position adjacent to Seoul's Incheon International Airport, with the airport's concentrated aviation operations and vehicle traffic on surrounding expressways generating elevated NOₓ alongside the surrounding steel, petrochemical, and logistics corridor. Yellow Sea maritime breezes provide coastal ventilation, while seasonal Chinese dust transport and the regional Northeast Asian industrial background elevate PM10 during spring dust episodes throughout the year.
