Ozone Safety Warning!!!

id they say what actually caused the premature deaths? Was it cancer, respiratory problems etc...?
I'm sure the full study does. I don't recall if the blurb in the NY Times said so or not.
Are there any issues with the minimal amount of ozone produced with UV units?
An underwater UV sterilizer that hobbyists use? IMO, no. Any small amount of ozone produced there will react with bromide in the water and form non-airborne products pretty rapidly.

That was the only concern they discussed, cancer.
One of the main byproducts of ozone reaction with seawater is bromate, a suspected carcinogen.

how about running something like this on the outlet side of the skimmer: http://www.ozonemeters.com/ODS-2P_product.html ?
Or even running a second air pump under the tank near the skimmer....
Only $80... Wonder if it's better/worse than carbon...

i own an ecoquest air purifier that has ozone in it is this bad for u honestly because ecoquest says its good go to here

My hot tub has an ozonizer running, and my wife and I use it almost every day. Wonder if I'm in danger. I also run chlorine in my hot tub, which is also been known to cause cancer. What about the carbon monoxide that they inject into fresh meat packages to keep in the color, I ve been eating that for years and years, that can kill you in high doses as well, don't walk though the muffler smoke of your car. I'm sure that's not good for you either. I am doomed, doomed! I'm going to go live in a bubble.
Oh and by the way: The practice of injecting carbon monoxide into meat packaging has been banned in some 3rd world countries. Wonder why??? US keeps doing it.. But this is another subject.
Don't get me wrong, I do think that using ozone one must be aware of the dangers, but lets not blow it out of proportion.

Industrial portable gas detectors for ozone are typically set for 0.1 ppm low alarm and 0.2 ppm high alarm based on government regulations (OHSA etc). Hey if you want breath that all day long and your kids developing lungs as well. For me I would prefer not to. People continue to smoke knowing the extremely harmful effects as well, go figure.......
I once read a article that suggested that oranges cause cancer. I think everything does!!! Seriously, ozone is dangerous at certain levels. What those levels are though is open to speculation. Would be nice to see some scientific proof. But then again they can prevent scientific proof that oranges cause cancer, so anything can be spun.

Never used ozone, but I always wondered about it's use in reef tanks. We monitor ozone levels 24/7 in our Cambridge, MA lab due to it's reactivity to various chemicals we work with. Inside our building, but outside of our ozone controlled areas, levels during the winter are very low (<5 ppb), but during the warmer days of summer levels peak at~50-60 ppb. Things are probably much higher outside. Commercial options for ozone control can be local around laboratory instruments with enclosures, or laboratory wide with special carbon based air duct filters. This can run 10-50k to modify a large air system. I don't know if there is a filter that can used, or if it would even work, for home use forced air. There are several companies that sell small units that claim to reduce ozone within a room. Not sure how well these work.

reefmuts, CO (carbon monoxide) will not harm you if it is packed in meat, right as the package is opened, the gas will diffues out into the air, and it qwill b in very low concentrations, that CO does is essentially czuses a sunburn like spot in your lungs, it literally cooks your lungs, which can cause various cancers im pretty sure, also in high doses it can kill you, it literally choks off oxygen until you fall asleep and die, it gives you a headache nad stomach ache, youd know if the CO in the meat was harming you, and it shouldnt be
as for the hot tub, thats a bit risky, runnign that thing is liek runnign a car, ozone is a secondary pollutant from car exhaust and sunlight as i stated earlier, so you are contributing to the pollution, now dont get me wrong one little hot tub wont do much, if anything at all, but get a bunch of those runnign all day, and it could be bad, but i think you would know if you were inhaling the O3 from the hottub, it should be safe for you, the chlorine, i was not aware of it causing cancer, but i wont doubt it, it an cause eye and skin irritation for sure, but as long as its not a gas it should be ok, i mena people swim in it every day, maybe in the long run in 100 years you might get cancer from it, but i wouldnt worry if i were you

My waste collector is an IO bucket. The buckett has a 1 inch ID flexible tube that extends from the outlet of the waste collector (most waste collectors have an outlet that allows carbon to be connected to it) to the exterior wall. I drilled a hole in the wall and stuck the tube through it, then sealed the edges with silicone. It works great year round, even on our cold winter nights!
Only thing to keep in mind is that a lot of condensation goes through this tube. The tube has to travel uphill or downhill the whole way. If it has a dip in it the condensation will slowly develop into a puddle and eventually block the line.
oh, i have a euroreef cs6-3, no waste collector.....................i had my air inlet run outside for ph purposes, till i realized why my skimmer kept overflowing................in the winter the cold air coming thru the tube would form condensation due to warm air around tube inside house, once the venturi sucked in this condensation it was all over....................

Air inlet does not work well for a skimmer (unless you take air directly from a heat exchanger) but an outlet works wonders with no effect from season to season.

I guess this could come in handy and it's cheap.....as cheap as it can get.

I can't beleive something so bad for you is used so much.. I also find it funny that some of these people worried about breathing in ozone probably smoke.. I don't understand how these smokers can be so concerned about occasionally breathing in a bit of ozone, but will inhale toxic smoke into their lungs on purpose and think nothing of it.....

Randy, the data you put in your initial post seems to be contradictory.
First you posted:
0.08 ppm Latest EPA study (to publish April 2006) reports significantly increased risk of premature death in humans. Each 0.01 ppm increase results in a 0.3 percent increase in early mortality.
Then later in the same post:
0.2 ppm
Prolonged exposure of humans under typical work conditions produced no apparent effects.
If prolonged exposure under typical work conditions (assuming 8 hours per day, 5 days a week = 2,080 hours a year) produced no apparent effects, how much exposure at less than 1/2 that concentration is it taking to have the significant increased risk of premature death? 24/7/365 exposure?
These just seem to contradict each other.

It is not a typo. The 0.08 ppm data is the new result that the EPA will publish, and is the reason for this thread. The other is the older, existing standard.
