Florence-Graham's air quality reflects the South Los Angeles basin's most challenging industrial suburban environment in unincorporated Los Angeles County, with vehicle emissions from I-710 Long Beach Freeway and the surrounding industrial and warehouse operations generating elevated diesel PM2.5 from freight traffic. The basin inversion traps all local emission sources, while the industrial corridor position and the adjacent rail freight operations consistently produce elevated readings throughout most of the year.
