Code red? Code PURPLE? What the f*?(23 posts)

Code red? Code PURPLE? What the f*?bill
Jun 26, 2003 5:59 AM
Yesterday around D.C., the air was Code Red, just this side of Code Purple. I was never very sure of what this means, but today somebody passed around some information on a local racer listserve. It's pretty harrowing stuff. And if you think that, because you're young and healthy you shouldn't let it worry you, that's not what this guy is saying. If you are active, drawing more of the stuff into your lungs, you're going to suffer more damage, pretty much guaranteed (in other words, the advice is the same for the eighty y/o that wants to go sit outside and the thirty y/o that wants to go ride his bike for an hour, or a half hour hard -- don't do it).
What he says is that the ozone destroys surface cells on your lungs. Which apparently do not rejuvenate the way epithelial cells do. So, you end up with scarred lungs, decreased performance for days or weeks, and possibly chronic inflammation.
I was going to go out at noon, today. Maybe I'll pass.
here's some info . . .bill

The effect on the lung tissue is less chemically toxic than it is a chemical
burn, doing physical damage to the epithilial tissue that makes up your
lungs. Any broaching of the integrity of the epithilial tissue is a problem
for the immune system. The real impact on the immune system is actually the
nitric oxide exposure, and this is present all the time. Only the
combination of heat and sunlight on VOC in the presence of nitric oxide(
from vehicle exhaust) lead to the formation of ground level ozone as a
secondary pollutant.

It is possible just
using the understanding that ground level ozone is a secondary pollutant
caused by the action of sunlight and heat on the primary pollutants VOC 's(
hydrocarbons from fossil fuel burning and natural emissions of turpenes and
related hydrocarbons by forests) in the presence of nitric oxide ( from
vehicle exhaust) to avoid damaging exposures. Early in the morning is cool
and the previous day's ground ozone has dissipated. Usually the levels arer
OK until 11:00 AM on even the developing worst days. There are exceptions.
Morning ozone levels tend to be very high, often the highest of the day,
overnight and into the morning hours in the Shenandoah National Park and The
Great Smoky Mountains National Park .There are multiple factors that lead to
this exception.

Use of the epa.gov/airnow or ww.deq.state.va.us/ozone sites to plan your
exercise time is perhaps the best way to avoid damaging exposures. An indoor
trainer is a viable option to be considered on some days.

The alveoli of the lungs are like brain cells: once damaged or destroyed,
they are not replaced in this lifetime. You may only use 10% of your
available brain cells, but you use 100% of your available alveoli.

Riders

The impact of ozone pollution on lung tissue is greater than many athletes
are aware of. The above link
is actual real time data as of 5:00 PM today. www.epa.gov/airnow will get
you to each states monitoring
info and forecasts. The Virginia DEQ site is one of the better ones for
actual data.

The one hour avg is the level athletes should be concerned with. This is the
actual level of ozone you are exposed to during a ride. At levels above 100
ppb ozone signifigantly damages the bronchioles by lipid peroxidation, and
damages red blood cells by the formation of hydrogen peroxide in the blood.
Currently the level of ozone ranges from 119-137 ppb in the DC metro area.

During training and competition, respiration rate increases at least
threefold. Total ventilatory increase is even greater due to deeper
breathing. The ozone is taken more deeply into the lungs than is typical
for the non-athlete. Clinical studies have demonstrated that even a
recreational athlete exercising in polluted areas experiences a threefold
greater exposure to pollutants than a sedentary person per time unit of
exposure.

The athletic performance damage done by excessive ozone exposure lasts for
several days to two weeks. The epithilial tissue of the lungs is damaged
somewhat akin to a sunburn and goes through a process of inflamation and
sloughing off of dead cells. The damage to the immune system done by nitric
oxide exposure also lasts for days. Chronic exposure is linked to the
development of asthma and chronic bronchitis in otherwise healthy
non-smoking adults.

The recommendation is that athletes avoid exposing themselves to prolonged
training or competition at ozone levels above 79 ppb one hour avg. Levels
above 120 ppb mean no outdoor athletic exertion period. The question is not
if your lungs will be damaged, even if only temporarily; rather, how much
will they be damaged and is the damage becoming chronic.

some (modest) hope . . .bill

There are some benefits to a supplement program in this regard. I don't give
blanket recommendations
for supplementation because every individual and situatuation is different.
That said, the clinical research
in this area seems to indicate that the typical supplemantal range of
vitamin E has some protective action. Also, the use of Co-Q10 enzyme,
vitamin C, and EFA ( flax oil) should included. That said, no supplement
program is going to protect you from the ozone levels seen this week. Akin
to a fire retardant driver's suit, the supplements slow the the onset of the
damage at a lower intensity, but at a more intense exposure you're going to
get burned.

question? asthma? limited time to ride?andy02
Jun 26, 2003 6:23 AM
This s??Ks! I live where I only get a limited time during the year to ride and now I shouldn't because I could do real damage to my lungs?? I already have a small amount of airway remodeling due to childhood asthma I don't need anymore trouble. does taking advair or simaler meds make it worse or prevent the inflamtion responce and therefore help?? I look on pubmed.

re: Not gettin what I paid forwilki5
Jun 26, 2003 6:39 AM
That's some great reading, informative and scary. Glad to see that the Canadian and American govt. are taking clean air seriously. It's about time industry and consumers got their act together. I'm sick and tired of paying for the person who drives their SUV/car everywhere (alone) or the industry that is allowed to voluntarily control emissions.

Right, the government is taking it seriously... just tell people to stay indoors, that's the solution all right!

Governments in NA are not taking it seriously at all. Bush's proposed voluntary emissions control program is a joke and there needs to be significantly more pressure on auto makers to improve fuel efficieny in in cars and especially SUV's

Interesting stuff. I rode in to DC this morning, and at 7:30 am the haze was already very thick. My riding buddy and I took it very easy after noticing that we were panting like beached whales on hills that normally wouldn't bother us. The effect was noticable.

Pollution is to blame, folks. Cars and power plants -- running full tilt to keep our AC on -- are to blame. Both of these can be cleaned up.

Check out the TV spots here, which are running in DC and several cities:

Anyone use those carbon filter masks?wilki5
Jun 26, 2003 7:44 AM
Any one use those masks with the little carbon filters in them? I know they get a bit hot in the summer but do they actually work at remove ozone, NOx and other pollutants?
Activated charcoal will kill ozone quickly ...Humma Hah
Jun 26, 2003 8:31 AM
... but I don't know which mask you're talking about. A cartridge-style mask that seals properly would work, but I don't know if it could keep up with heavy breathing at your AT.

We used an activated charcoal canister to scrub ozone from air for an ozone analyzer I used to be involved with building. That was used to set the zero baseline on the instrument. The destruction of ozone was virtually instantaneous and total. I believe we also used charcoal to scrub hydrocarbons, sulfur compounds, and oxides of nitrogen, but it was not as total and fast as it was for ozone.

Activated charcoal is even fairly effective against nerve gas.
Question about O3Alex-in-Evanston
Jun 26, 2003 8:50 AM
What is it about hot days that raises the ground-level ozone concentration? Is the third oxygen coming from SOX or NOX or some other source? Is the heat responsible for the reaction? If so, what temps are required?

Thanks,

Alex
