Just as the title says really, I seem to be seeing a lot of mixed results on this subject but I am very curios if it can give you cancer if inhaled or ingested etc.

It is speculated that ingestion is the most dangerous route for nitrates which is ironic given that preservatives is one of its most widespread uses. In the body, acids can decompose nitrates to nitrites, which are suspected carcinogens.

A quick google search yields many results.

i have question slightly off topic. i have read articles about carbon on burnt food be carcinogenic. this apparently has something to do with carbon be produced from burning producing a carbon ion. bit beyond my knowledge. but my thinking was if this is right doesn't that mean the same for charcoal. with the amounts be breathed in while working with bp, has anyone else heard of this?

Al powder- i presume you refer to alzheimers disease.

Its never ACTAULLY been proven, that there is a link between increased levels of Al + alzheimers.

What does exist, is factual evidence based around increased levels of Al traces in patients who ALREADY have the disease........

Still though, better not to inhale it......Why not go the whole hog, and buy a used NATO s10 respirator. It'll protect you from any chemical you choose to use, and in the unfortunate event of say a flash explosion, it'll save your face. and your eyes.

but not your arms, legs and body so you will just have a protected head :> good for the police I suppose to know who you are

Aluminium has had bad press for a long time, mostly beginning around the 1920s. Rudolph Valentino's death in 1926 at the tender age of 31 was blamed on aluminium poisoning from aluminium cookware - but he was actually killed by a perforating stomach ulcer. Howard J. Force, a self-proclaimed "chemist" added momentum to the anti-aluminium movement with pamphlets such as Poisons Formed by Aluminum Cooking Utensils. It was probably not a coincidence that he also sold cookware - stainless steel cookware.

The first scientific "evidence" about aluminium's toxicity appeared in the mid-1970s. People with Alzheimer's Disease have typical changes in the brain that can be seen only with a microscope. They're called "neuro-fibrillary tangles". Various studies found high concentrations of aluminium at autopsy in the brains of people suffering with Alzheimer's Disease - and almost always in the characteristic neuro-fibrillary tangles in the nerves. So, did the aluminium cause Alzheimer's Disease? No. It eventually turned out that the neuro-fibrillary tangles were very "sticky" - and absorbed the aluminium out of the water used to wash them.

But around the same time, a brand-new aluminium-related disease appeared - "Dialysis Encephalopathy". By the mid-1970s, patients with chronic kidney failure were now routinely being treated with a new technique called "dialysis". It used hundreds of litres of water each day to purify the blood. Unfortunately, the aluminium naturally present in the water entered the blood, and couldn't be removed - because the kidneys weren't working. As the blood levels of aluminium soared to thousands of times higher than normal, the patients became confused and demented. As soon the problem was recognised, this "Dialysis Encephalopathy" was fixed by removing the aluminium from the water.

So, giving aluminium in massive concentrations directly into the blood of very sick people with failed kidneys did cause dementia. But there are lots of causes of dementia. Alzheimer's Disease is one of these. The dialysis patients, even though they had very high aluminium levels and dementia, never developed the neuro-fibrillary tangles, that are characteristic of Alzheimer's Disease.

On average, we each take in about 10 - 50 mg of aluminium per day. But even people who take antacids and buffered aspirin, which bumps up their aluminium intake to 1,000 mg of aluminium per day, have no increased incidence of Alzheimer's Disease.

Dr. Charles DeCarli, the director of the Alzheimer's Disease Center at the University of Kansas Medical Center says, "In my opinion, the supposed relation between aluminum and Alzheimer's Disease is a simple case of neuromythology".
