Column: The dirty history of L.A.'s smog (via latimesopinion)
If you think the smog is bad now, you should have been here 50 years ago. Or just wait – because it may come back. The Trump administration has stripped California of the power the state has had for more than 50 years ago to help keep smog at bay by setting stricter vehicle emission rules. That power has delivered cleaner air and fewer health complications to generations of Angelenos. And now that power could disappear into thin – and filthier – air.
You may know what L.A.’s epiphany was and when it was when, L.A. looked around and said, God, this is really bad, and we can do something about it. We know a tremendous amount about the effects of air pollution, both short-term and long-term effects on people. Certainly the lung is the primary organ for which there are effects and we know a lot about it. But it goes far beyond the lungs, because once it crosses the air blood barrier in the lungs, it gets into the blood in the circulatory system and then essentially the contaminants could go anywhere in your body.
What percentage of smog now is produced by cars -- because cars are cleaner, and the dirtier cars are getting aged out? What percentage still comes from factories or construction, when the Air Quality Management District has had rules in place on those for a while too? But certainly because of their sheer number and the breadth of activity, motor vehicle emissions are a major problem in Southern California.
Is climate change chiefly why we have seen more smog, even smog alerts, I think, for parts of Southern California and the Central Valley?
