隨著全球霧霾氣候頻發(fā)，PM2.5的損害也被更多的人注重。除了會引發(fā)各種呼吸疾病、心血管疾病外，PM2.5也被確以為一級致癌物，大大添加了肺癌的得病概率。與抽煙比較，有不少人以為室外的PM2.5污染對人類的損害比抽煙還大?？梢灿胁簧偃艘詾榫退悴怀闊熖焯煲舱諛訒隤M2.5，我多抽幾支又何妨！現(xiàn)實究竟如何呢？跟著小編接著往下看吧：
With the global climate of haze frequent, PM2.5 damage is also more people pay attention to. In addition to causing respiratory diseases and cardiovascular diseases, PM2.5 is also believed to be a carcinogen and greatly increases the risk of lung cancer. Compared with smoking, many people think that outdoor PM2.5 pollution does more harm to human beings than smoking. But many people think that even if not to smoke every day will still be inhaled PM2.5, I take a few more what! What is the reality? Follow Xiao Bian and go on:
?揚州市環(huán)保局大氣主動監(jiān)測室曾做過一個實驗：一支煙徹底焚燒，將發(fā)生0.62克顆粒物，其間PM2.5占30%~40%，約等于0.19~0.25克。如此，假設(shè)在一個密閉的100平方米的房間里，這些卷煙焚燒顆粒物發(fā)生的PM2.5濃度約為633.3~833.3微克/立方米。依照國家標準75微克/立方米核算，超支了8~11倍！
Yangzhou Environmental Protection Agency atmospheric active monitoring room has done an experiment: a cigarette completely burned, will occur 0.62 grams of particles, during which PM2.5 accounted for 30%~40%, approximately equal to 0.19~0.25 grams. So, in a confined 100 square meter room, the PM2.5 concentration of the burning particles in these cigarettes is about 633.3~833.3 micrograms per cubic meter. According to the national standard of 75 micrograms / cubic meter accounting, overruns 8~11 times!
若以北京某天的PM2.5濃度與卷煙發(fā)生的最低PM2.5濃度值來核算，霧霾天沉積進肺泡無法排出的PM2.5約為吸煙的6.5倍。
If one day Beijing PM2.5 concentration and the minimum PM2.5 concentration of cigarettes to be accounted for, the haze days deposited into the alveolar can not be discharged PM2.5, about 6.5 times the smoking.
所以吸6.5支煙就相當(dāng)于在中度污染的環(huán)境中24小時所吸入的PM2.5的量。經(jīng)研討標明，PM2.5吸入沉積量，每添加144微克，心肺疾病死亡率上升6%，肺癌死亡率增加8%。因而，在PM2.5濃度較高的霧霾天里吸煙，無疑是落井下石。PM2.5繼續(xù)高濃度的效果下，長時間吸煙使肺部所受損傷將更顯著。
So smoking 6.5 cigarettes is equivalent to the amount of PM2.5 inhaled in the moderately polluted environment for 24 hours. The study showed that PM2.5 inhalation deposition, every 144 micrograms added, heart lung disease mortality increased by 6%, lung cancer mortality increased by 8%. Therefore, smoking in the haze days the higher concentration of PM2.5, is undoubtedly worse. PM2.5 continued high concentrations of the effect, the longer smoking, lung damage will be more significant.
