随着全球雾霾气候频发，PM2.5的损害也被更多的人注重。除了会引发各种呼吸疾病、心血管疾病外，PM2.5也被确以为一级致癌物，大大添加了肺癌的得病概率。与抽烟比较，有不少人以为室外的PM2.5污染对人类的损害比抽烟还大。可也有不少人以为就算不抽烟天天也照样会吸入PM2.5，我多抽几支又何妨！现实究竟如何呢？跟着小编接着往下看吧：
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:
扬州市环保局大气主动监测室曾做过一个实验：一支烟彻底焚烧，将发生0.62克颗粒物，其间PM2.5占30%~40%，约等于0.19~0.25克。如此，假设在一个密闭的100平方米的房间里，这些卷烟焚烧颗粒物发生的PM2.5浓度约为633.3~833.3微克/立方米。依照国家标准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浓度与卷烟发生的最低PM2.5浓度值来核算，雾霾天沉积进肺泡无法排出的PM2.5约为吸烟的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支烟就相当于在中度污染的环境中24小时所吸入的PM2.5的量。经研讨标明，PM2.5吸入沉积量，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浓度较高的雾霾天里吸烟，无疑是落井下石。PM2.5继续高浓度的效果下，长时间吸烟使肺部所受损伤将更显着。
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.
