Some components of smoke are characteristic of the combustion source. Guaiacol and its derivatives are products of pyrolysis of lignin and are characteristic of wood smoke; other markers are syringol and derivates, and other methoxy phenols. Retene, a product of pyrolysis of conifer trees, is an indicator of forest fires.
A 2011 report in the International Journal of Environmental Research and Public Health (IJERPH) lists 65 carcinogens or possible carcinogens: "Our list of hazardous smoke components includes all nine components reported in mainstream cigarette smoke that are known human carcinogens (IARC Group I carcinogens), as well as all nine components that ...
Tobacco smoke, besides being an irritant and significant indoor air pollutant, is known to cause lung cancer, heart disease, chronic obstructive pulmonary disease (COPD), emphysema, and other serious diseases in smokers (and in non-smokers as well). The actual mechanisms by which smoking can cause so many diseases remain largely unknown.
Wildfire smoke is toxic. Wildfire smoke is a concoction of gases like carbon monoxide, hazardous air pollutants, water vapor, and particle pollution, according to the United States Environmental ...
Because exhaled smoke exists at lower temperatures than inhaled smoke, chemical compounds undergo changes which can cause them to become more dangerous. As well, smoke undergoes changes as it ages, which causes the transformation of the compound NO into the more toxic NO 2. Further, volatilization causes smoke particles to become smaller, and ...
Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
There are toxic components of the smoke of herbal cigarettes which are similar to regular cigarettes. [3] Aminobiphenyl can cause bladder cancer. [3] CO can be fatal in "low concentration of approximately 667 μg/mL." [3] CO can cause coronary artery disease as well. [3]
Smog, or smoke fog, is a type of intense air pollution. The word "smog" was coined in the early 20th century, and is a portmanteau of the words smoke and fog [ 1 ] to refer to smoky fog due to its opacity, and odour. [ 2 ]
