"Special compounds - such as ambient nitrous acid, nitrogen dioxide or ozone - is featured in a lot of free air that was in the room," said Hugo Destaillats, who led the research at Lawrence Berkeley National Laboratory in California , USA. This is because that is generated by burning gas supplies outside the room where the fire or the use of electronic equipment.
Destaillats and equipment they use cellulose as a model foreign material, and place a barrier inside a smoker truck for three days. Then analyzes these barriers and compare the results of laboratory tests on the basis of cellulose-based were exposed to nicotine evaporates in a tubular flow reactor. "We found that some of the [ambient gas in the] truck to react with residual nicotine to produce snuff-specific nitrosamines, known carcinogens."
Two of these compounds - N-nitroso nornicotine (NNN) and 4 - (methylnitrosamino) -1 - (3-pyridyl)-1-butanone (NNK) is also found in the smoke of snuff, as has been well studied in the past. However, a third compound was identified that is not unusual in the smoke of snuff: 1 - (N-methyl-N-nitrosamine) -1 - (3-pyridinyl)-4-butyraldehyde), called nna. Because of this there was no smoke, nna not been investigated in detail, but this team of experts toksikologist now hope that this will some studies.
Unlike second-hand cigarette unconsciously breathe in public areas, the dangers of secondhand smoke is not clear roots. There are many factors involved, from the size and ventilation of the outdoor environment of the materials used berbedayang - mikrolayer of the toxin can accumulate lint, wallpaper, clothing and hair.
"One of the specific risk groups such smoke are children," said Jonathan Winickoff, a pediatrician who has studied teacher attending the dangers of cigarettes a third hand of the Harvard Medical School. «Children interact with their environment in ways that are very different, so their exposure can be 20 times higher than in adults."
"I think this is important work that will create scenarios for a study on residual contamination of snuff smoke," said Winickoff. "The consequences of third-hand smoke is the absence of a way for someone to smoke outside the room without pollute the environment. "
