Are the fumes emitted from Dura-Flame fire logs (especially the crackle color type) dangerous?  Toxic?

Shouldn't be!\nIf you are experiencing an odd smell I suggest you check the flue (see Link 2.).\nIf you are worried about fumes in the room then there is probably something wrong with the flue and the correct air-flow is not occuring.

I wouldn't worry about breathing in smoke while doing pooja.  If you were in a room with a lot of smoke, the smoke and related gases displaces the oxigen and eventually it becomes dangerous for you to be there.  But as long as you light your droop, camphor, incense in open areas with ventilation, you will be ok.

Uh, The sources on air purifiers creating toxic fumes seem to be reliable.  On the other hand, you have such a difficult time with spelling that I can't really trust your scientific knowledge.

Mercury, sulphur dioxide, nitrous oxides, particulate matter, and carbon dioxide are all products of burning coal. Sulphur dioxides, mercury, nitrous oxides and particulate matter may be reduced, but aren't entirely eliminated by stack gas cleaning. Where power plant cooling water is reintroduced back into a water body as warmer water this can also have  negative effects on aquatic life. \n\nThe other side of the hazards of coal have been in the news lately. Underground mines can be dangerous places to work, and have in the past been much more dangerous. There are also health hazards such as Black Lung disease for underground coal miners. In 2004 the US Black Lung Disability Trust Fund paid out $292 million to miners and their families. \n\nStrip mines have gotten better at replacing overburden and  top soil when they have finished mining, but long term permanent damage remains in the form of ground water pollution from disturbed bedrock. In the past strip mines often left their mined out areas as wastelands that were unsuitable for most uses. In some areas entire underground aquifers are drained in order to strip mine coal, leaving nearby farms unable to use their wells for water supply. \n\nOccasionally older underground coal mines begin to subside. Entire towns have been damaged by collapsing underground passages in some areas. Another hazard of some underground coal mines is that they sometimes catch fire after they have been abandoned. These deep underground fires burn very slowly but often have very negative effects on the surface above the fire, and can burn for decades. \n http://www.offroaders.com/album/centralia/centralia.htm

We use smoke bombs in hvac work all the time. For example inspections.Air leaks etc...

Eating food or drinking water contaminated with high levels of creosotes may cause a burning in the mouth and throat, and stomach pains.\n\nBrief direct contact with large amounts of coal tar creosote may result in a rash or severe irritation of the skin, chemical burns of the surfaces of the eyes, convulsions and mental confusion, kidney or liver problems, unconsciousness, and even death. Longer direct skin contact with low levels of creosote mixtures or their vapors can result in increased light sensitivity, damage to the cornea, and skin damage. Longer exposure to creosote vapors can cause irritation of the respiratory tract.\n\nLong-term exposure to low levels of creosote, especially direct contact with the skin during wood treatment or manufacture of coal tar creosote-treated products has resulted in skin cancer and cancer of the scrotum. Cancer of the scrotum in chimney sweeps has been associated with long-term skin exposure to soot and coal tar creosotes. Animal studies have also shown skin cancer from skin exposure to coal tar products.\n\nThe International Agency for Research on Cancer (IARC) has determined that coal tar is carcinogenic to humans and that creosote is probably carcinogenic to humans. The EPA has determined that coal tar creosote is a probable human carcinogen.\n\nThere is no unique exposure pathway of children to creosote. Children exposed to creosote will probably experience the same health effects seen in adults exposed to creosote. Children who played on soil contaminated with creosote had more skin rashes than children who played in uncontaminated areas. It is unknown whether children differ from adults in their susceptibility to health effects from creosote.\n\nStudies in animals have shown birth defects in the young of mothers exposed to high levels of creosote during pregnancy, but no similar studies have been performed on humans. Some animal studies indicate that creosotes may cross the placenta and reach the fetus. Because chemical components (PAHs, cresol, phenols) of coal tar creosote may be stored in body fat, they may be found in breast milk and could pass to nursing infants.\n\nIn 2003 the European Union banned creosote for amateur and unlicenced professional use, due to concerns over these health effects, noting that recent research had shown that the risk of skin cancer had perhaps been underestimated previously.

I would have to know more. Fire is a scary thing. A few years ago I had to help my cousin get her horses out where she was in California. We had to paint phone numbers on the horses in case of separation. It came one block up to her house. The smoke was unreal. \n I would hate to see anything burn.\n And yes I have heard of one serious fire that we had. I would hope we didn't sacrifice one for the other. But I need to know more to say this was a bad thing.

hardwood such as oak or maple. \nEucalyptus burns really hot and smells good - but the creosote will build in your chimney,

Any Hardwoods.  Oak, cherry, redwood, etc.  Stay away from pine.  It smokes and pops alot.  Make sure it was seasoned for a cleaner burn.

I am more scared of fire.  I am a fireman, and their is nothing more harmful than the toxic gases and carbons that are released from poralysis.

I don't know that there is any evidence of this.  I think the danger is in inhaling the smoke of burning leaves.  \n\nIf there is any danger in your job, I would think that there would be more danger in the chemical additives used then the tobacco itself.

What you saw is called foxfire. It is quite common and most people who have spent much time camping outdoors have seen it. \n\nSorry to spoil the mystery but it isn't very unusual.\n\nFoxfire is caused by fungi that lives on dead wood. (It is NOT caused by bacteria, nor is the glow in beach sand caused by bacteria.) For reasons nobody has worked out yet these fungi glow very slightly in the dark.\n\nIn this case it was almost certainly caused by a honey mushroom. Normally the fungus exists as thin  threads called mycelia that grow under the bark of the tree so they can't be see.  Whent he tree fell the outer layers of bark were knocked off and the fungus became visible.\n\nYou can photograph foxfire, but not with a digital camera. You need a film camera with and a tripod and vriable exposure time. Set the exposure to 30 seconds or more.

I remember a girl in the news who ended up inhaling a piece of the X'nas tree and ended up getting a horrid asthma attack.  For years she lived with it until she was operated on about 10 years later.  After extracting the snall twig the leaf parts still had chlorophyll in it.

Well, it is a strong oxidant especially in an acidic form, so it could be a problem if it leaked onto anything combustible.  It is also very hazardous to health and environment, so accidental exposure can be a problem.   It will emit very toxic fumes in a fire situation, so it can be quite hazardous to firefighters, especially if they don't know its there.\n\nSome plastics may become brittle with age if it is stored too long, leading to breakage and leakage.\n\nI would say that is the biggest hazard, being accidentally exposed to to an improper containeer or labeling.

The smoke from the wood is many times more carcinogenic than tobacco

the best way is to find out when there is wast pick op, or in my area the fire stations once a week will have a truck that all u have to do is drop off you waste and they will dispose of it properly,  burning it will cause harmful toxins in the air and could even be fatal if inhaled.
