据中国之声《新闻纵横》报道，中国科学院近日公布了“大气灰霾追因与控制”专项课题组的最新研究结果。研究结果表明，近期持续、大范围的强雾霾中，含有大量的含氮有机颗粒物。

According to the sound of China[News aspect]reports,The Chinese academy of sciences has released"Atmospheric gray haze chase for and control"The latest research results of the special group.The results of the study show that,The sustained recent/A wide range of strong fog in the haze,Contains a lot of nitrogenous organic particles.

　　有媒体报道说，这种含氮有机颗粒物类似农药对人体危害极大。昨天(17日)，北京的风不小，但PM2.5依然居高不下，从上午8点至下午3点，一直在200微克每立方米以上，属于重度污染，直到晚间，才被风吹落至中度污染。但这已经比上个月动辄400微克每立方米以上的严重污染要好得多。

Media reports said,The nitrogen organic pesticide particles similar to human body harm greatly.yesterday(17),Beijing big wind,But PM2.5 is still high,From 8 a.m. to 3 PM,Have been 200 micrograms per cubic meters above,Belongs to the severe pollution,Until the late evening,To blow down to moderate pollution.But it has more than 400 micrograms per cubic meter of last month frequently more serious pollution is much better.

　　“大气灰霾追因与控制”专项课题组负责人、中科院大气物理研究所研究员王跃思说，造成近期持续、大范围的强雾霾事件，有多方面的原因。

"Atmospheric gray haze chase for and control"The special group/Chinese academy of sciences researcher at the institute of atmospheric physics WangYueSi said,Cause the sustained recent/A wide range of strong fog haze events,The reason that has many sided.

　　王跃思：根据目前研究的结果，今年1月份强霾污染事件的原因：第一是大范围天气过程的原因，形成了静稳天气；第二，沙尘的叠加；第三，偏南气流湿度大，水汽会使干细的粒子迅速膨胀，成为肉眼能够分辨出来的颗粒；第四，冬季燃煤产生二氧化硫、汽车尾气产生氮氧化物及有机物，在静稳空气中产生化学反应，转变成大的粒子，形成雾霾天气。

WangYueSi:According to the present the results of the study,In January this year strong haze pollution incident reason:The first is the cause of a wide range of weather process,Form the static stability of the weather;The second,Superposition of the dust;The third,By south air humidity is big,Water vapor can make dry fine particle rapid expansion,Become the naked eye can distinguish out particles;The fourth,Winter coal produced so2/Car tail gas produce nitric oxide and organic matter,In the static stability air produce chemical reaction,Into a large particle,Form fog haze weather.

　　王跃思说，自然原因固然是一方面，但如果没有人为的粗放式排放，雾霾就不会这么强烈、持续时间不会这么长、影响范围也不会这么广。

WangYueSi said,Natural causes is a hand,But if there is no artificial extensive emissions,Fog haze will not so strong/Duration of time won't be so long/Scope of influence wouldn't be so wide.

　　而最让研究人员感到震惊的是，在雾霾中发现了一种含氮有机物，这种物质的危害在于成分太过复杂。

And the most let researchers are shocked,In the fog haze found a nitrogenous organic matter,This kind of material is the harm of composition is too complicated.

　　王跃思：这次分析结果让我感到很震惊的是，分析过程中发现大量含氮的有机物，它的成分非常复杂。它不是一种，而是好几十种物质。这种物质对人体的伤害是，可能引起癌症及其它严重疾病。还有更重要的是，病毒、病菌都能在这种很小的颗粒物上存活，附着在大气的颗粒物上，就会传播疾病。

WangYueSi:The analysis results let me feel very shock,In the course of analysis found that a large number of nitrogenous organic matter,Its composition is very complicated.It is not a,But the scores of material.This kind of material is to the harm of human body,May cause cancer and other serious diseases.There are more important,virus/Germs can in this small particles on live,Adhere to the atmospheric particles on,Will spread the disease.

　　而更为复杂的，是近期强雾霾的形成机制。

And more complicated,A recent strong fog haze formation mechanism.

　　王跃思：目前中国灰霾天气的形成机制非常复杂。京津冀地区也有二氧化硫的污染，这种污染就跟1952年伦敦烟雾的化学成分是一样的；而我们检测出来的有机氮氧化物，跟美国洛杉矶上世纪四五十年代开始的光化学烟雾中检测出来的物质是一样的。但这两个过程同时在京津冀发生，另外京津冀还受到沙尘的影响。

WangYueSi:At present Chinese gray haze weather formation mechanism is very complicated.Beijing-tianjin-hebei region also have so2 pollution,This kind of pollution with 1952 London smog chemical components are the same;And we detected organic nitrogen oxides,With the American Los Angeles last century forty or fifty s to photochemical smog detected in the material is the same.But the two process at the same time in beijing-tianjin-hebei happen,In addition beijing-tianjin-hebei is influenced by the influence of the dust.

　　1952年，伦敦烟雾事件，12000人丧生；而始于上世纪四五十年代的洛杉矶光化学烟雾事件，至少800人殒命。

In 1952,,London smog event,12000 people were killed;And the last century began in forty or fifty s Los Angeles photochemical smog event,At least 800 people have died the final death.

　　当有健康甚至是性命之忧时，“戴着防毒面具上街”就不仅仅是一个笑话了。王跃思说，戴口罩的确可以减少空气中的有害颗粒，但并不适合所有人。

When there is health and even life when the sorrow,"Wearing a gas mask to go shopping"It is not just a joke.WangYueSi said,Wearing a mask can indeed reduce harmful particles in the air,But is not suitable for all people.

　　王跃思：老年人一定要慎戴口罩，因为戴口罩之后容易造成老年人缺氧。尤其是心肺功能不全的老人，很可能危及到生命。孩子应该减少运动，一运动，就会吸入更多的空气，会引起对心肺的更多伤害。建议在雾霾天老人和孩子尽量不要出门，戴口罩毕竟不是长久之计，所以每个人一定要从自身做起，为大气污染物减排做出贡献。

WangYueSi:Old people must careful wearing a mask,Because wear a face mask to old people after caused by oxygen.Especially cardiopulmonary insufficiency of the old man,Is likely to endanger the life.Children should be to reduce motion,A movement,Just breathe more air,Will cause more damage to the heart.Suggestions in the fog haze days old people and children not to go out as far as possible,Wear a face mask, after all, not a permanent solution,So everyone must starts from oneself,For atmospheric pollutant emissions to contribute.

　　王跃思认为，如今要想根治雾霾恐怕还做不到，只能是通过努力，借鉴其它国家和地区的治理经验，尽量减少雾霾出现的频率和强度。

WangYueSi think,Now want to effect a radical cure fog haze I'm afraid I still can't do,Only through hard work,Learning from other countries and regions management experience,Try to reduce the fog haze the frequency of the occurrence and strength.

　　王跃思：借鉴伦敦的治理经验，我们要减少燃煤过程中二氧化硫、氮氧化物的排放；而对照洛杉矶，就要减少氮氧化物、挥发性有机物的排放。除了减少这四种污染物以外，我们还要减少地面扬尘、浮尘的影响。所以要治理，肯定就得从根源上入手，减少排放、恢复生态系统功能，这样才能把整个中东部地区大气中的污染降下来。

WangYueSi:Reference to the London management experience,We want to reduce coal process of so2/Nox emissions;And control the Los Angeles,To reduce nitrogen oxides/Emissions of volatile organic compounds.In addition to reduce these four outside pollutants,We have to reduce ground dust/The influence of dust.So to control,Must have the root of from,Reduce emissions/Recovery of ecological system function,In order to put the whole area of middle atmospheric pollution drop down.

　　对于雾霾天气的治理，王跃思强调，目前我们不仅需要某一个地区的应急预案，更重要的是区域性的联防联控。毕竟“污染物扩散是区域性的，它们不受行政区划的限制。他还说，空气污染一时半会解决不了，但是公布这个研究结果，就是提示公众要注意防护。

For the management of fog haze weather,WangYueSi emphasize,At present, we not only need a certain areas of the emergency plan,More important is the regional integrated defense.After all"Pollutant diffusion is regional,They shall not be restricted by administrative divisions.He also said,Air pollution is a half will not solve,But announced the results of this study,Is prompt the public to pay attention to protection.

　　“毒雾”之下，没有人能够独善其身。与当年造成严重后果的伦敦毒雾相比，我国的雾霾目前还只是阶段性出现，持续时间也不算很长。但我们决不能放松警惕，从现在起，政府、企业、个人共同努力，做好应对雾霾的最坏打算，也许才能正找回遮蔽的蓝天。(记者肖源)

"Poison fog"under,No one can possess.And the serious consequences than London poison fog,China's fog haze at present is still in stage,Duration is not very long.But we must not let down their guard,From now on,The government/enterprise/Personal efforts,Prepared to cope with the worst fog haze,Maybe to find shelter is the blue sky.(Reporter XiaoYuan)
