Abstract from DBPedia
    Smoke is a collection of airborne particulates and gases emitted when a material undergoes combustion or pyrolysis, together with the quantity of air that is entrained or otherwise mixed into the mass. It is commonly an unwanted by-product of fires (including stoves, candles, internal combustion engines, oil lamps, and fireplaces), but may also be used for pest control (fumigation), communication (smoke signals), defensive and offensive capabilities in the military (smoke screen), cooking, or smoking (tobacco, cannabis, etc.). It is used in rituals where incense, sage, or resin is burned to produce a smell for spiritual or magical purposes. It can also be a flavoring agent and preservative. Smoke inhalation is the primary cause of death in victims of indoor fires. The smoke kills by a combination of thermal damage, poisoning and pulmonary irritation caused by carbon monoxide, hydrogen cyanide and other combustion products. Smoke is an aerosol (or mist) of solid particles and liquid droplets that are close to the ideal range of sizes for Mie scattering of visible light.

    煙(けむり)は、気体中に固体または液体の微粒子(10µm程度未満)が浮遊している状態。 煙には有害な微粒子を含むことが多く意図して作られるものではない場合が多い。煙害など人体への影響を考慮する場合は、微粒子群だけでなく微粒子を含む気体もあわせて考慮する必要がある。火事での死亡事例の多くは、煙を吸い込み、呼吸困難になるため発生する。煙を排出する設備が排気管や煙突である。一方で通信手段として利用されてきたほか、燻蒸・燻煙式の殺虫剤などにも利用されている。
