What city has the worst smog?



  1. 0 Votes

    Bakersfield, California, has the worst smog in the U.S.  Because of it’s proximity to L.A., it’s climate and terrain (mountains) that traps smog, and fertilizers and pesticides from farms, it takes the top spot in the American Lung Association’s assessment of smoggiest cities.  Other top offenders are L.A. itself, and Pittsburgh, which actually had a smog incident in 1948 that was so toxic it killed people and sickened thousands.
