吸煙(yan)(yan)(yan)(yan)(yan)過(guo)(guo)程(cheng)中生(sheng)(sheng)成(cheng)(cheng)(cheng)的(de)(de)(de)(de)煙(yan)(yan)(yan)(yan)(yan)焦(jiao)(jiao)油(you),約為(wei)原煙(yan)(yan)(yan)(yan)(yan)草重量(liang)的(de)(de)(de)(de)1~6‰,煙(yan)(yan)(yan)(yan)(yan)焦(jiao)(jiao)油(you)的(de)(de)(de)(de)產量(liang)與吸煙(yan)(yan)(yan)(yan)(yan)的(de)(de)(de)(de)頻(pin)率有一(yi)定的(de)(de)(de)(de)關系(xi)。單位(wei)時(shi)間(jian)內吸的(de)(de)(de)(de)次數越(yue)多(duo)(duo),焦(jiao)(jiao)油(you)的(de)(de)(de)(de)生(sheng)(sheng)成(cheng)(cheng)(cheng)量(liang)就越(yue)多(duo)(duo)。每分(fen)(fen)鐘(zhong)吸3口(kou)煙(yan)(yan)(yan)(yan)(yan)生(sheng)(sheng)成(cheng)(cheng)(cheng)的(de)(de)(de)(de)焦(jiao)(jiao)油(you)量(liang)幾乎比每分(fen)(fen)鐘(zhong)吸1口(kou)煙(yan)(yan)(yan)(yan)(yan)多(duo)(duo)1倍。焦(jiao)(jiao)油(you)的(de)(de)(de)(de)生(sheng)(sheng)成(cheng)(cheng)(cheng)量(liang)也(ye)與紙煙(yan)(yan)(yan)(yan)(yan)長度有關,這是(shi)可以想(xiang)像到(dao)的(de)(de)(de)(de),因為(wei)煙(yan)(yan)(yan)(yan)(yan)草點燃(ran)處(chu),生(sheng)(sheng)成(cheng)(cheng)(cheng)的(de)(de)(de)(de)煙(yan)(yan)(yan)(yan)(yan)焦(jiao)(jiao)油(you)煙(yan)(yan)(yan)(yan)(yan)霧,通過(guo)(guo)紙煙(yan)(yan)(yan)(yan)(yan)未燃(ran)燒(shao)部位(wei)時(shi),其中一(yi)部分(fen)(fen)被煙(yan)(yan)(yan)(yan)(yan)草所吸附。當點燃(ran)處(chu)越(yue)來(lai)越(yue)接近末端時(shi),生(sheng)(sheng)成(cheng)(cheng)(cheng)的(de)(de)(de)(de)焦(jiao)(jiao)油(you)幾乎大部分(fen)(fen)都進入到(dao)吸煙(yan)(yan)(yan)(yan)(yan)者呼吸道中,一(yi)支卷煙(yan)(yan)(yan)(yan)(yan)的(de)(de)(de)(de)前半(ban)截(jie)與后半(ban)截(jie)生(sheng)(sheng)成(cheng)(cheng)(cheng)的(de)(de)(de)(de)焦(jiao)(jiao)油(you)量(liang)之(zhi)比約為(wei)1∶1.4,雪(xue)茄煙(yan)(yan)(yan)(yan)(yan),斗煙(yan)(yan)(yan)(yan)(yan)和水煙(yan)(yan)(yan)(yan)(yan)的(de)(de)(de)(de)焦(jiao)(jiao)油(you)生(sheng)(sheng)成(cheng)(cheng)(cheng)量(liang)都比紙煙(yan)(yan)(yan)(yan)(yan)少。
利群香煙焦油的危害
1、致癌
是確定致癌物,能(neng)誘發人體細(xi)胞突(tu)變(bian),抑制(zhi)人體免疫功(gong)能(neng)的(de)發揮,這已為醫學(xue)研究(jiu)所證明(ming)。
2、加速血管硬化
人(ren)體衰老是(shi)一個幾十年(nian)(nian)的過(guo)程(cheng),這幾十年(nian)(nian)里(li),血(xue)(xue)管(guan)逐步硬化(hua)(hua)、喪失彈(dan)性;這一過(guo)程(cheng)是(shi)無法逆轉的,平時(shi)服用保健品只能延(yan)緩(huan),并不能返老還童,吸煙者血(xue)(xue)液內溶有一定的焦(jiao)油成(cheng)分,作用于(yu)血(xue)(xue)管(guan)管(guan)壁,加速血(xue)(xue)管(guan)硬化(hua)(hua),對于(yu)腦(nao)血(xue)(xue)管(guan)和心血(xue)(xue)管(guan)這些脆弱部分更加敏感,近些年(nian)(nian)來(lai),心腦(nao)血(xue)(xue)管(guan)疾病是(shi)影響人(ren)們健康的第一殺(sha)手,與香煙有著直接關(guan)系(xi)。
