After years of alleged improvements, Los Angelenos are breathing the most polluted air in six years.
"Just how poor was air quality this summer? Unhealthful air developed somewhere across Southern California, on average, almost every other day since May 1, the start of the smog season. There were nearly 30% more smoggy days than were recorded last year. Yet, the highest ozone measurement this year was 80% higher than the federal limit a concentration that prompted air quality officials to declare a first-stage ozone alert, the first in Southern California in five years, when air is dangerous for everyone to breathe." Los Angelinos still breathe the most polluted air in America.
