Is burning copper dangerous

Page 1 of 2  
Is burning copper dangerous? I am asking because I was camping and tossed some copper dust in the fire to make the flames colorful. The flames were really nice, but some drunken guy in the next camp was having a fit about it, saying that burning copper emits dangerous fumes that when breathed are toxic and of course, according to him, ALL the smoke was going his direction. I told the guy to either get lost or to call the police on us, and they would settle it. (since he was the one that was drunk, and we were not, I knew that would be fun). Anyhow, I just wanted to ask and find out if there really is any truth to his claim. (The idiot packed up and left in the morning, which was great for us, because we got rid of the moron and had a bigger camp). .

Greetings,
Toxicity is not black and white. Many things are toxic (or toxic enough to matter) only above certain levels. If you inject 6 oz of water into an 8 oz lab rat it will die. Copper is toxic. Your small amount of copper dust in the fire as a demonstration isn't going to hurt anyone but I am sure that someone will tell you different if you ask enough people. I am sure the drunkard lost more braincells that night to what he had been drinking than injured his body due to the copper.
Hope this helps, William

Some info about copper toxicity:
" Copper is a heavy metal that is toxic in its unbound form. Almost all of the copper in the body is bound to proteins, thereby reducing the concentration of unbound copper ions to almost zero. Most diets contain enough copper (2-5mg daily) to prevent a deficiency and not enough to cause toxicity. The World Health Organization (WHO) suggests that 10-12mg per day may be the upper safe limit for consumption. If as little as 2gms of a copper salt are ingested, usually with suicidal intent, the resulting copper-induced hemolytic anemia and kidney damage are generally fatal. "

PS: Yes, I know you were talking about the fumes but thought you might find this interesting anyway.

Where did you get "copper dust"? Was it pure copper? OR was it a copper compound, such as copper sulfate or copper chloride?

The stuff is sol commercially with no particular warnings. OTOH, inhaling any smoke is not good as it contains particulates.

The Human body needs Copper in a very little amount but large doses , i would think would not be good for you in large volume of it. Protein in the human body is good for you but protein in large volume has the effect of rattle snake venom in the body. Rattle Snake Venom is 100% pure protein which will damage the human body if subjected to the human body.
Also there is something about they not making pots and pans out of copper for some reason. this could be your reason why it is suppose to not be breathed into the body.
Anything to a excess will kill you. Drinking 5 gallion of water a day will kill you.

If Rattle Snake Venom was 100% pure protein, it'd be a solid ;-)
Protein is a class of organic chemicals. Some are extremely toxic in small doses, most are relatively innocuous, and won't do anything other than make you sick if you ate vast quantities of it. Most snake venoms have proteins that attack specific parts of your biochemistry, whether nervous system or ones that can best be described (somewhat inaccurately) as corrosive (they _digest_ you).
There's more protein in a handful of peanuts or a slice of meat than there is in a snake bite.

Many pots have copper _external_ layers to promote better heat distribution, but not on the interior. I've been hearing some health warnings about copper clad pans recently.
Copper is toxic to invertibrates (which is why, for example, copper is used in wood preservatives and aquarium disinfectants) in very low dosages. Driving copper nails into a tree will kill it. It's only logical to assume that higher dosages will be toxic to people. And it is.
I'd believe a small amount of "flame color" chemicals thrown in a fire won't be a serious health issue, but not if you were directly downwind and got it in your face. Copper sulfate smoke, for example, will be quite acrid (sulfur compounds, ie: SOx, if nothing else are a bit hard on the lungs - forms sulfuric or sulphurous acid in contact with moisture - ie: the inside of your repiratory tract/lungs. Ugh.).

For sure.

I picked up some articals here on the Millwaukee Public Museum and a spokesman of Gary Casper. Where he states that Rattle Snake venum is Protein and does the effect to the animal or human they bite. http://www.mpm.edu/collect/vertzo/herp/timber/bites.htm
The words you spoke about protein effectring the body in small amounts is true but not in the way you told it.
You can drink rattle snake venum and not hurt you at all. now if you inject a very little bit into your blood stream directly by a needle. It will kill you or come close to killing you. The way the rattle snake venum effects the human body is the venum is almost pure protein which when injected into you blood stream, will have bad effects on the human blood stream and the body. it just in so many words over loads the human body with protein which it is not use to being done to it. When people get use to being bite all the time , they are getting use to being over loaded with protein in their system and can handle the high protein dose. usely after being bite about 10 timers you be come use to it and it will not bother you. now if you get away from the american rattle snakes you change the venum and it can get real poison in it like the Coral snake which will work on the nerves system.
Also about all snake venum protein being a solid. I always thought snakes injected people and other animals with a liquid venum all these years and not a powdered venum. now when I say rattle snake venum is just about all protein is they use protein to mess with the pray and mess it up from running. now other forms of snakes uses all kinds of different poisins to kill or stop the pray. When they don't have protein in the injections to the pray to stop them. It will be referred to by other names as poisins or Toxin . now the Diamond back Rattlers here in Louisiana does use protein to stop it's pray from running away and also to stop humans from hurting them.

Turtle, only a dumb ass idiot would drink, or say you can drink snake venom. A small unnoticed stomach or intestional ulcer would move it into your blood stream, and could kill you. Wake up.

been there and done that. i got into this type argueement about uslers letting venum into the human body. we had to get two Doctor opinion to settle it and both said it would be very little effect of having usler and drinking rattle snake venum for the usler would stop all transfer of liquid at all. another example of this was if a body builder would drink his high protein drinks and have a usler. it would kill him because of the over dose of Protein. also the doctors said any of the venum to effect the body it would have to be injected to do any good at all.
Now thank you Dr. Ransley for you informing use of a new medical break through !

You've completely misunderstood what he said. Snake venom isn't dangerous because it's made up of proteins, it's dangerous because they're made up of specific proteins with specific properties.
Read the article more carefully - they're talking about, for example, proteins with hemorrhagic or anti-coagulant properties. Other proteins attack, for example, your nervous system. But certainly not all proteins have such effects. Most don't. For example, Adrenalin is a protein. Digestive enzymes are proteins. Most drugs are proteins.
"Proteins" are, quite simply, a huge family of chemicals (hundreds of thousands of different chemicals) with a huge variety of effects. Meat is made up out of proteins. Many plants (especially legumes and nuts) have large quantities of proteins. _You_ are made up of proteins. There are hundreds (probably thousands) of different proteins coursing through your bloodstream right _now_.
You could take, for example, several grams of ordinary food protein and inject it directly into your bloodstream, and while it might have some effects (your kidneys and/or liver wouldn't like it), it probably wouldn't hurt you.
In contrast, the proteins in snake venum (oh heck, now you have me misspelling it - "venom"!) are toxic. As in actively poisonous. Milligrams of some of these poisons will kill you.

I was referring to the suggestion that venom was 100% protein. Pure proteins are solids. Snake venom is _actually_ mostly water with dissolved proteins.

You misunderstand that too. Venoms (whether snake, bee, wasp, spider...) are virtually all protein based, because that's what biological organisms produce. As is adrenalin, and most of all the other chemicals your body produces to make it function.
All venoms are poisonous/toxic substances. When scientists start talking about the science of how the toxin _works_, they become more precise with their language of what it's _made_ out of.
In other words, "poison" and "toxin" are words describing their effects. "Protein" is a word used to mean that the chemicals involved are some variety of protein.
Saying a snake venom is a protein doesn't mean all proteins are toxic, in the same way as thinking the phrase "cars have 4 wheels" means that all 4 wheeled vehicles are cars.

The post before you said there was very little or no protein in the rattle snake venom and now you changed your mine and state now that the snake venum is just about all protein !
The protein is what makes you sick or kills you and does all the damage. i was in a hospital one time for being bite by a Cotton Mouth and the doctor told me that the effect on me was the effect of the Protein over loading my system with protein which it is not use to being subjected to. a example of this is take a car and then have it running and then take a gas can and pour a gallion of gas in the intake of the engine. it will mess up or die but this is the same effect as over loading your system with protein.
now explain to me about the % protein snake venum is now after 2 trys.

You have some very serious comprehension problems Turtle. I said nothing of the sort.
There are only _milligrams_ of active ingredient in snake bites, the rest of it is water. When you say that "it's all protein", that implies that the whole thing is protein. Obviously, it _can't_ be, because venom is liquid, but pure protein is a solid.

Your postings all implied that _all_ proteins did this. Obviously, that's nonsense.

An example of your comprehension problem. No doctor would say that "any old protein will have a similar effect, and it's simply a matter of getting used to it." Anyone who did needs to get their license revoked.
Increasing tolerance to snake bite venom is mostly a myth. Most snake bites in North America are not life threatening in the first place. This "tolerance" is simply that the person becoming more and more unconsciously aware it's not a big deal, not panicking, and getting appropriate care without stressing out.
Meanwhile, with the more life-threatening varieties (such as cobra venom), in reality you usually become more and more sensitive (increasing severity of reaction) each time. So much so that people who handle them learn that after a while, even immediate anti-venom won't save them.
Or, they get allergic to the anti-venom - so much for getting "used to that protein".

Hi Turtle,
I don't think that there is nearly as much controversy over copper utensils as there is currently is over aluminum pots and pans. At one time there was a lot of concern about aluminum intake and Alzheimer's disease.

I really don't know about the Al. pots being use and the effect but one thing i do know and that is all people with Alzheimers disease has a very high level of aluminum in their blood stream. there has to be a connection there.

100% of people who have Alzheimers have at some time consumed water! There MUST be a connection there. In fact, 100% of people who have ever died have at some time consumed water. It must be a deadly poison!
In January, I painted my house red, and closed all the open windows. Painting my house red made it much warmer!

Have you ever seen the MSDS for dihydrogen monoxide? They need to ban it. It's everywhere and it's REALLY DANGEROUS!
But governments refuse to do so.
Coverup! Coverup!
Seriously, tho, there seems to be some interesting evidence pointing elsewhere as a cause for Alzheimer's. Alzheimers tends to be more prevalent in industrialized countries. Which could of course simply be because those people tend to live longer to encounter it. However, there's one undeveloped third world area that has had a _drastic_ jump in Alzheimers over the past 10-15 years, and it's thought to be a big jump in the consumption of (if I recall correctly), Cassava root. Which, if I'm not mistaken, is toxic unless prepared properly, and suspicions are mostly aimed at certain chemicals in the root that are essentially identical to chemicals used as plasticizers in the plastics industry.
Meanwhile, other people are pointing fingers at plasticizers because they bioaccumulate, and are beginning to be found in surprising quantities in people (ie: in breast milk).
