平時(shí)炒菜時(shí)總是會(huì)散發(fā)出的油煙，所以很多人的廚房煙囪什么的都是黑黑的，那么，油煙的危害有哪些呢?其實(shí)油煙是食用油和食物在高溫條件下，產(chǎn)生的大量熱氧化分解產(chǎn)物。

　　Usually cooking will always emit smoke, so many people's kitchen chimneys, what are black, then what are the hazards of soot? In fact, soot is a large amount of thermal oxidative decomposition products produced by cooking oil and food at high temperature.

　　烹調(diào)時(shí)，油脂受熱，當(dāng)溫度達(dá)到食用油的發(fā)煙點(diǎn)170℃時(shí)，出現(xiàn)初期分解的藍(lán)煙霧，隨著溫度繼續(xù)升高，分解速度加快，當(dāng)溫度達(dá)250℃時(shí)，出現(xiàn)大量油煙，并伴有刺鼻的氣味，油煙粒度在0.01微米-0.3微米。

　　When cooking, heating oil, when the temperature reaches the oil smoke point of 170 DEG C, the early decomposition of blue smoke, as the temperature continues to rise, the decomposition speed, when the temperature reaches 250 DEG C, appeared a lot of smoke, and accompanied by the pungent odor of smoke particle size of 0.01 micron in 0.3 micron.

　　有關(guān)部門從居民家庭收集的經(jīng)常煎炸食物的油煙樣品進(jìn)行分析，共測(cè)出220 多種化學(xué)物質(zhì)，其中主要有醛、酮、烴、脂肪酸、醇、芳香族化合物、酯、內(nèi)酯、雜環(huán)化合物等。在烹調(diào)油煙中還發(fā)現(xiàn)揮發(fā)性亞硝胺等已知突變致癌物。 油煙氣被人體吸入后使呼吸道粘膜損傷，并降低人體免疫功能。油煙刺激人們的眼睛，誘發(fā)心血管疾病。有關(guān)資料顯示，在致肺癌因素中，烹調(diào)油煙是僅次于“深度吸煙”煙霧到達(dá)呼吸道深部的危險(xiǎn)因素。如果吸煙和烹調(diào)油煙的危害，可使肺癌減少85%。

　　Relevant departments to collect from households often fried food smoke samples were analyzed by 220 kinds of chemical substances, which are mainly aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, esters, lactones, heterocyclic compounds. Volatile known carcinogens such as nitrosamines have also been found in cooking oil fumes. When the smoke and fumes are inhaled by the human body, the respiratory tract mucosa is damaged and the immune function of the human body is lowered. Soot stimulates people's eyes and induces cardiovascular diseases. Relevant data show that, in the cause of lung cancer, cooking fume is second only to the "deep smoking" smoke into the deep respiratory tract risk factors. If the harm of smoking and cooking fume is eliminated, lung cancer can be reduced by 85%.
