Children who regularly participate in outdoor sports during days on which ozone pollution is high are more likely to develop asthma. Long-term exposure to ozone produces a small, permanent decrease in lung function.

Do you remember the odor? Ozone has a smell akin to the odor produced by lightning, which is a large generator of the gas.

Here's what an online MSDS has to say about Ozone....

"Causes dryness of the mouth, coughing, and irritates the nose, throat, and chest. May cause difficulty in breathing, headache, and fatigue. The characteristic sharp, irritating odor is readily detectable at low concentrations (0.01 to 0.05 ppm).

OSHA PEL limits follow...

Exposure Guidelines:
OSHA PEL: 0.10-ppm PEL/TLV

If you read this carefully you'll note that you can smell Ozone at OSHA PEL levels... Did you in fact smell ozone?

Here's the "money shot"....

"Ozone is an unstable gas which, at normal temperatures, decomposes to diatomic oxygen."

This is from a European Site...

"Toxicity data

IHL-HMN TCLO thought to be near 1 ppm/2h.
IHL-CAT LC50 34500 ppb/3h
IHL-GPG LC50 24800 ppb/3h
IHL-HAM LC50 10500 ppb/4h
IHL-HMN LCLO 50 ppm/30m

LC50 lethal concentration 50 percent kill
LCLo lowest published lethal concentration
LD50 lethal dose 50 percent kill
LDlo lowest published lethal dose

The long and short of it is that I don't think you had problems with Ozone. If you had problems they weren't large enough to warrant a trip to the Hospital, where a competent person would have evaluated you for the CAUSE of your complaints (and your suppositions of same decades later).

LA is #1 for short term and year round particulates..

also, people who live in LA don't usually have chest pain either, but coming from very low pollution to heavy will cause chest pain. Its just like smoking cigarettes. Someone who has smoked for years doesn't even feel it going down. A first time smoker will cough out a lung.

I'll take your little snit as confirmation that nobody took you to the ER. Otherwise you'd have furnished proof of respiratory distress. You might have had reaction to pollen, fungi, food, or some other environmental assault. You just THINK you were affected and use this supposition as "justification" to launch onto someone who doesn't share your joy at our Almighty Government saving us from industry.

Look, do your homework. Where I come from I deal with facts and the facts do not necessarily support your claims of past injuries or support your current joys at Our Masters in DC telling us what we're gonna be driving.
