I know that it's a good sign, but it could be used as a scapegoat. Polluters can now say that they can keep the level of polluting products that they currently have.

Rats.

Ac, can you post a link to what you found, if possible?

[Acriku]

It isn't seasonal, the decreasing size during what you have said were normal, but this was to a higher degree. It's promising but it's just a start.

I didn't find it on the internet I saw it on msnbc, but I'll look for it online.

[emprworm]

i dont think the ozone hole is oil related.

[Inoculator9]

Do you mean, you don't think it was the result of oil?

[Anathema]

No, it's eaten by certain gasses (forgot the name)- like the ones used by some deodorants. Burning oil gives Co2, but that is not ozon related.

[Inoculator9]

Of course burning oil has an affect. If it didn't no one would care about using it. But it isn't the major contributer, house hold products are the major cause.

[Anathema]

Oil does not affect the ozon layer.

And the major polluter is cars.

Chlorofluorocarbons (CFCs)

Chlorofluorocarbons (CFCs) are compounds containing carbon, chlorine and fluorine.

Chlorofluorocarbons (CFCs) are sold under the trade name of Freons.

Used as working fluids in refrigerators and air conditioners because they are gases at room temperature wich can be easily liquified by compression and because they are stable and non-toxic

Used as foaming agents in the production of polystyrene and polyurethane foam plastics used for insulation and packing materials

Used as a propellant in spray cans for paint, insect repellants, deodorants

[Anathema]

Yeah thanks that's the stuff I meant :).

[nemafakei]

... but these have been made illegal in some countries - they are here - anywhere else?

[Anathema]

Here deodorant use substitutes- though I don't know if it goes for other things, let alone if it is illegal.

[Inoculator9]

Isn't chlorine a CFC?

[DjCiD]

it is found in cfc's

[Inoculator9]

I doubt that any country could outlaw swimming pools with a straight face.

Yes. About 10 years ago, scientist across the world met to discuss the theory of ozone depletion. It wasn't proven back then, fortuneately, the evidence was enough to warrant international legislation against chlorofrlourocarbons in all products. There are other ways to make air conditioners, fridges, and aerosol cans, so it didn't hurt any industry and really saved face of the southern continents.

Chlorine is in pools, yes, but CFS (chloroflourocarbons) are NOT in pools. CFC is the name for a compound/mixture, it is unrelated to chlorine.

Its like salt. Take chlorine (a poisionous substance), mix it with sodium and you get sodium chloride, an ionic compound also known as salt. Salt doesn't share the properties of of chlorine or sodium. It is a completely different subtance, so we can digest it.

[Inoculator9]

I got mixed up, sorry.

[SurlyPIG]

No worries. It's a bizzare concept in chemistry. What baffles me is that hydrogen and oxygen, two of the most flammable and fire-promoting gases in existance, form to make water, which as you surely know is the best way to fight fire. Wierd, isn't it?

[Inoculator9]

Yeah, a lot of wierd stuff, like metals melting at room temperature. Nutty :).

huh?

[Anathema]

Wich metals? Some metals are already liquid at room temperature.

[zamboe]

Sure,

Mercury (Hg), it's in liquid state at about 20 Celcious (293 K), i am not sure about the exact temperature. Wanna see ? See any termometer's bulb.

[nemafakei]

Many thermometers are alcoho-based, now; mercury based thermometers tend to be used less, due to the fact that if broken, you have some mildly poisonous metal on your hands.
