二手烟PK汽车尾气 一支烟释放的PM2.5是尾气2.2倍 Secondhand smoke PK car exhaust a smoke release of PM2.5 tail gas is 2.2 times

　　据中国之声《新闻晚高峰》报道，近日，吸二手烟和闻汽车尾气，哪个对人体危害更大的报道，引起了人们的广泛热议，同样是被动吸食有害气体，到底哪个更毒，记者也进行了调查采访。

According to the sound of China[News late peak]reports,recently,Secondhand smoke and automobile exhaust smell,Which is more harmful to human body reports,Caused the people's extensive hot debate,The same is passive smoking harmful gas,Exactly which more poison,Reporters also to carry on the investigation interview.

　　山东临沂市民吴女士是一家外贸公司的白领，平时注重养生的她，因为不能忍受同事的二手烟，打了张"禁止吸烟"的标志，贴在了自己的电脑上。

Shandong linyi citizens ms wu is a foreign trade company white-collar,Usually pay attention to health preservation of she,Because can't stand his colleagues secondhand smoke,Played a"No smoking"Sign of,Posted on the own computer.

　　吴女士：记得我当时是打印了标志，怕同事熟视无睹，然后我就直接贴到我的电脑对面，也就是他的正对面。

Ms wu:Remember I was printed sign,Afraid of colleagues turn a blind eye to,Then I'll post my computer directly opposite,He is too is opposite.

　　吴女士说，她觉得，不是因为个人体质敏感的问题，二手烟的危害对所以年龄段的人同样存在。

Ms wu said,She felt,Not because of personal physical sensitive issue,The dangers of secondhand smoke to so age paragraph the person also exist.

　　吴女士：也不是敏感，我觉得这个味道太大了，谁都能闻到。吸二手烟的人比吸一手烟的人危害更大，容易引起肺癌。我从电视上也有看过这方面的报道，吸二手烟的人本身受到的危害是更大的。

Ms wu:Is not sensitive,I think the smell is too big,Anyone can smell.Secondhand smoke than suction skill of smoke more harmful,Easy to cause lung cancer.I also have seen on television this aspect of the report,Secondhand smoke by themselves the hazard is greater.

　　对于最近热议的二手烟和汽车尾气，谁对身体的危害更大的问题，吴女士也说出了自己的看法。

In the recent hot discussion of secondhand smoke and automobile exhaust,Who to the harm of the body more problems,Ms wu have even voiced their opinions.

　　吴女士：二手烟，别人吸的时候你能看得见那个烟雾多大啊，闻到的味道也特别大，只不过烟有时候是小面积的污染，大家以为很快就散去了，好像不厉害。它应该会比汽车尾气还厉害。汽车尾气消散在空气里大家看不到，就以为它不厉害，我们一天在路上的时间可能不多，上下班的时间还开着车窗，但是在办公室里或者在家里，如果你身边的人吸烟的话，你接触的时间要长的多。

Ms wu:Secondhand smoke,Others suction when you can see the smoke much ah,Smell the smell also particularly big,Only smoke is sometimes a small area of the pollution,Everybody thought that soon ended,Seems not bad.It should be more severe than a car tail gas.Automobile exhaust gas lift in the air you can't see,Just think that it is not too bad,We a day on the road may not much time,The time to open the window,But in the office or at home,If the people around you word of smoking,You contact the time longer.

　　众所周知，香烟内还有尼古丁、焦油、亚硝胺、重金属、悬浮颗粒物、一氧化碳等有害物质，多达300余种；而二手烟的危害，主要是吸烟时释放出的一氧化碳和PM2.5，这两样物质在汽车尾气中也大量存在。对于这两种物质的危害，临沂市人民医院大夫马颖霞：

As is known to all,In the cigarettes and nicotine/tar/nitrosamines/Heavy metal/Suspended particles/Carbon monoxide and other harmful substances,As many as more than 300 kinds of;And the dangers of secondhand smoke,Smoking is mainly released when the carbon monoxide and PM2.5,These two material in automobile exhaust also abounding.For these two kinds of material damage,Linyi city people's hospital doctor MaYingXia:

　　马颖霞：这个一氧化碳气体无色无味，也没有刺激性，自然界中很常见，但是含量很少，人吸入以后，红细胞输氧能力会降低，体内缺氧，会产生头晕、呕吐，严重的可能还会导致昏迷、甚至窒息死亡。我们熟知的就有煤气中毒，大多数就是因为一氧化碳引起的。PM2.5是指大气中直径小于或等于2.5微米的微粒物，这个一旦进入人体肺部就很难排泄出，就会引起哮喘、支气管疾病，还有心血管病等等。

MaYingXia:The carbon monoxide gas colorless insipidity,No irritation,The nature is very common,But few content,People after suction,Red blood cell oxygen ability can be reduced,Oxygen in,Will produce the dizziness/vomiting,Serious may also lead to coma/Even suffocation death.We know there is gas poisoning,Most is because carbon monoxide.PM2.5 refers to the atmosphere diameter less than or equal to 2.5 micron WeiLiWu,This once in a person's lungs are difficult to drain out,Will cause asthma/Bronchial disease,And cardiovascular disease, etc.

　　到底是二手烟危害大，还是汽车尾气更毒，针对这一问题，相关机构的对比试验显示：在20平方米的房间内吸3支烟，PM2.5浓度超标43倍，而在一辆1.8L排量的家用轿车内的测试则显示，一根香烟释放出的一氧化碳含量，不及汽车尾气高；而PM2.5浓度却是汽车尾气的2.2倍。这和它们的燃烧方式有很大关系。香烟是烟草燃烧，它本身也有一定颗粒物成分；而汽车尾气主要是汽油燃烧，汽油中含有很多烃类挥发性有机物，所以从PM2.5这项指标上看，二手烟中的浓度，确实要比汽车尾气高，而且这种颗粒物一旦吸入肺部，是很难排出体外的，然而，有很多司机却喜欢在车内吸烟。

Exactly is secondhand smoke hazard big,Automobile exhaust or more poison,In order to solve this problem,The correlation organization the contrast experiment shows:In the 20 square meters room suction 3 cigarettes,PM2.5 concentrations exceed bid 43 times,And in a 1.8 L displacement household cars within the test is display,A cigarette release carbon monoxide content,Automobile exhaust not high;And PM2.5 concentration is 2.2 times of automobile exhaust.This and their combustion mode has a great relationship.Cigarettes are tobacco burning,It is also a certain particle composition;And the car tail gas is mainly combustion of gasoline,Gasoline contains a lot of hydrocarbon volatile organic compounds,So from the index PM2.5 watch,Secondhand smoke in the concentration,Do more than car tail gas high,And the particles once inhalation lung,It is difficult to discharge the in vitro,however,There are a lot of driver is like smoking in the car.

　　市民郭先生：就是因为困了啊，或者是心里不得劲了啊，就想抽颗烟，跑起来就抽，一天的话，得10支以上。

Citizens Mr Guo:Is because tired ah,Or is the heart BuDeJin ah,Want to smoke a cigarette,Run will smoke,One day word,Have more than 10 pieces.

　　因为车内空间小，污染程度更高，在车内吸一支烟，一氧化碳浓度为15毫克/立方米，超标3.5倍；PM2.5浓度为10毫克/立方米，超标高达133倍。临沂市人民医院大夫马颖霞：

Because the space is little car,Pollution level higher,A cigarette in the car,Carbon monoxide concentration is 15 mg/cubic meters,Overweight 3.5 times;PM2.5 concentrations to 10 mg/cubic meters,Overweight is as high as 133 times.Linyi city people's hospital doctor MaYingXia:

　　马颖霞：二手烟和汽车尾气对人体危害都很大，尤其是一些特殊人群，你像孕妇、老人、孩子更容易受到伤害。汽车的尾气是个大环境，需要全社会一起出台治理规定，采取一些措施，减少汽车尾气排放。吸烟就是一个小环境，吸烟的人只要注意都可以做到，尽量不吸烟，尤其是在可能影响到他人的时候要自觉，对自己对他人的身体健康都是好事情。(记者邢斯嘉)

MaYingXia:Secondhand smoke and automobile tail gas to human body harm is great,Especially some special groups,You like pregnant women/The old man/Children more vulnerable to damage.The car tail gas is a big environment,Need the whole society governance provisions on together,Take some measures,Require lower emissions from automobiles.Smoking is a small environment,People who smoke as long as attention can do,Try not to smoke,Especially in May affect other people's time to consciously,To oneself to other people's health is good thing.(Reporter XingSiJia)
