Los Angeles' Koreatown air quality reflects the densely urbanised inner-city corridor, with vehicle traffic on Wilshire Boulevard and Olympic Boulevard generating some of the Los Angeles basin's most sustained urban NOₓ and PM2.5 in this extraordinarily dense multi-storey residential neighbourhood. The flat basin position and the persistent temperature inversion maintain Koreatown at consistently elevated inner Los Angeles basin readings and the vehicle density on Wilshire makes this one of LA's more traffic-exposed residential communities.
