中新网沈阳1月17日电 (记者 秦逸)近日来，沈阳连续出现灰霾天气。中国医科大学附属盛京医院第二呼吸内科谭明旗教授17日接受记者采访时表示，广大民众要做防“灰”指南。他建议，冬季没有患病的人群(尤其是儿童、老人等弱体质者)可以通过注射流感疫苗来加强预防，食用一些清肠润肺的食物，有些许辅助作用。

Beijing shenyang on January 17 (Reporter QinYi)In recent days,Shenyang continuous appear gray haze weather.China medical university affiliated hospital of internal TanMingQi shengjing second breathing professor 17 when accepting a reporter to interview said,The general public to do prevent"ash"guide.He suggested that,Winter no sick people(Especially children/The old man and the weak constitution)Can through the vaccination to strengthen prevention,Eat some clear bowel runfei food,There are some supplementary role.

　　随着城市化进程的快速发展，人类活动直接向大气排放大量粒子，污染气体越来越多。灰霾天气就是由此产生的污染型天气。灰霾发生时，细粒子浓度升高，大量极细微的干性尘粒、烟粒、盐粒等均匀地悬浮在空气中，严重危害人体健康。

With the rapid development of urbanization,Human activities directly the discharge into the atmosphere of a large number of particles,Pollution gas more and more.Gray haze weather is the resulting polluting the weather.Gray haze occurs,Fine particle concentration increased,A large number of imperceptible dry dust particles/Smoke particle/Such as YanLi evenly suspended in the air,Serious harm to human health.

　　谭明旗介绍说，近年来研究发现，灰霾天气的发生与PM2.5(颗粒物小于2.5μm的颗粒物)污染密切相关。国内外大量流行病学研究资料表明，细颗粒物浓度上升与肺部疾病的发生率、死亡率关系密切。

TanMingQi said,In recent years, the study found,Gray haze weather occurrence and PM2.5(Particles less than 2.5 u m of particle)Pollution is closely related to the.A large number of epidemiological studies at home and abroad show that material,Fine particulate concentration rise and the incidence of lung disease/Closely related to mortality.

　　为什么PM2.5可以引起呼吸道疾病呢？这是因为大于10μm的颗粒物被鼻和呼吸道黏液排除，10μm以下的颗粒物可进入鼻腔，7μm以下的颗粒物可进入咽喉，小于2.5μm的颗粒物(即PM2.5)则可深达肺泡并沉积，进入血液循环，导致与肺功能障碍有关的疾病。

Why PM2.5 can cause respiratory disease?This is because more than 10 μ m of particle is nose and respiratory tract mucous ruled out,10 μ m the following particles can into the nasal cavity,7 μ m the following particles can enter the throat,Less than 2.5 u m of particle(Namely PM2.5)Go down to the alveolar and deposit,Into blood circulation,Cause and pulmonary dysfunction related diseases.

　　颗粒物可以导致引起慢性支气管炎、哮喘、慢性阻塞性肺疾病急性发作。加拿大和美国科学家发现，长期处于细颗粒物浓度较高环境中的人群患肺部疾病的几率和肺癌的死亡率增高，可以出现眼和喉部刺激、咳嗽、呼吸困难、鼻塞流涕、皮疹、等症状，其中儿童和老年人患病的几率更高。

Particles can cause chronic bronchitis/asthma/Acute attack of chronic obstructive pulmonary disease.Canada and the United States scientists found,In the long run, fine particulate concentration is higher in the environment with the risk of lung disease and lung cancer mortality rate increase,Can appear eyes and throat stimulation/cough/Difficulty breathing/A blocked or watery/rash/Symptoms such as,The children and the elderly are more likely to illness.

　　此外，灰霾天气还会对人体健康产生一些间接影响。如减弱紫外线的辐射，影响人体维生素D合成，使空气中传染性病菌活性增强。灰霾天气还会影响人们的心里健康，使人产生压抑、悲观等不良情绪。

In addition,Gray haze weather will also to the health of human body produce some indirect effects.Such as weaken the ultraviolet radiation,Affect human body vitamin D synthesis,Make the air infectious bacteria activity enhancement.Gray haze weather can also affect people's heart health,Make the person produces depressive/Sadness, bad mood.

　　谭明旗提醒人们，要做防“灰”指南，做好四点。一是避免户外运动最重要。老年人避免晨练，尤其是8点之前，否则，越是运动，吸入肺部的毒物越多，无形中成了毒雾的吸尘器。抵抗力较弱的孩子应该尽量呆在室内，防止患上呼吸道疾病。

TanMingQi remind people,To do prevent"ash"guide,Do four.One is the most important to avoid outdoor sports.Old people avoid do morning exercises,Especially before eight,otherwise,The movement,Suction lungs more poison,Has virtually become poisonous fog vacuum cleaner.Resistance is weak children should try to stay indoors,Prevent suffering from respiratory diseases.

　　二是低碳生活少开车。从自身做起，低碳生活，出门少开车，多使用公共交通工具，减少汽车废气排放，PM2.5就与汽车尾气有关。还有就是加强体育锻炼，增强抗病抵御能力，提高自身免疫力。

The second is the low carbon life driving less.Starts from oneself,Low carbon life,Go out driving less,Many use public transport,Reduce automobile emissions,PM2.5 and the car tail gas.There is more exercise,Resistance to resist ability,Improve their immunity.

　　三是使用空气净化设备。目前市场上的一些空气净化器，对于室内净化有显著效果，有效的去除空气中的污染物，尽量避免和减少空气污染的危害。

Three is the use of air purification equipment.Currently on the market some air purifier,For indoor purification has remarkable effect,Effective removal of pollutants in the air,Try to avoid and reduce the impact of air pollution.

　　四是冬季建议没有患病的人群(尤其是儿童、老人等弱体质者)可以通过注射流感疫苗来加强预防，食用一些清肠润肺的食物，有些许辅助作用。(完)
