转眼已是深冬季节了，天气已经变的越来越冷，雾霾情况从入冬以来一直都较为严重，根据专家提醒，雾霾天最好少出门。那么，我们的室内空气就确定很好吗？下面，我们我们详细的讲诉一下，为什么说冬季更要注意室内空气检测治理？

Now is the winter season, the weather has become more and more cold haze from since the beginning of winter has been more serious, according to experts, the best go out the haze days. So, will our indoor air be very good? Below, we speak in detail, why should we pay more attention to indoor air inspection and control in winter?

问题一

One problem

室内生活时间增多

Increase in indoor life time

据有关机构的调查显示，现代人在室内生活的时间越来越长，调查结果显示，城市人群每天大约有80%的时间在室内，而冬季比夏季增加10%以上，能够达到90左右。特别是一些室内工作者、儿童、老人和体弱多病者，在室内逗留的时间更长。

According to the survey of related agencies, the time of modern people living indoors is getting longer. The survey results show that the urban population has about 80% time indoors per day, while the winter is increasing by more than 10% over the summer, reaching 90. In particular, some indoor workers, children, the elderly and the weak and infirm, stay in the room longer.

其实这一点我们很好看见的，在冬季室温温度较低，在北方室内有暖气，人们一般都会选择待在室内；在南方虽然没有暖气，但是在没有阳光的情况下室内还是比室外温暖多了。特别是今年，入冬以来南方一直以阴雨天气为主，那么人们待在室内时间更是久。另外一方面，有了外卖，吃饭都懒得出去，有可能室内时间是100%。

In fact, we can see this very well. In winter, when the room temperature is low and the heating is indoors in the north, people usually choose to stay indoors. Although there is no heating in the south, it is much warmer than the outside when there is no sunshine. Especially since the beginning of winter this year, the South has been dominated by wet weather, so people stay indoors time is long. On the other hand, with a takeout, you can't have to eat out, and it's possible that the room time is 100%.

问题二

Question two

呼吸系统疾病增多

Increased respiratory disease

在我国老年人发病死亡率时间分布调查结果中显示，每年的12月至次年的2月份是我国老年人发病死亡高发时间段，要比全年的平均数高出4倍之多。某医学研究院院长分析到，这种情况与秋冬季的气候、环境有直接关系，通过实验证明细菌可以附着于细小尘粒在空气中漂浮，这种细小尘粒被接触者吸入即可传染疾病。秋冬季人体的免疫力相应比较低，细菌和病毒对人们健康的危害更大。

In the survey of the time distribution of morbidity and mortality of the elderly in China, it shows that the incidence of death in the elderly in China is 4 times higher than that in the whole year from December to February of the next year. The dean of a medical research institute analyzed that this situation is directly related to the climate and environment in autumn and winter. It is proved by experiments that bacteria can be attached to fine particles floating in the air, and this tiny dust particles can be infected by inhalation of contacts. In autumn and winter, the immunity of the human body is relatively low, and the bacteria and the virus are more harmful to people's health.

据了解入冬以来，在医院门诊的人数中，大约有40%是呼吸道疾病，这要说和空气污染没有关系，小编肯定是不相信。就中国去年年末的三个月，雾霾波及的范围之广，造成的影响之大都是罕见的，特别是个别地方的PM2.5突破1000，更是让人唏嘘。就室内来讲，室外的雾霾这么大，躲在室内就没事吗？从得呼吸道的疾病人数来看，应该不是没事的。

It is understood that since the winter, the number of hospital outpatient, about 40% were respiratory diseases, and to the air pollution Never mind, Xiao Bian is certainly not believe. For the three months of the end of last year, the impact of haze spread is very rare, especially in some places where PM2.5 breaks through 1000. As far as the room is concerned, the haze of the outdoor is so big, is it okay to hide in the room? From the number of respiratory diseases, it should not be all right.

问题三

Question three

通风排污效果降低

Reducing the effect of ventilating and discharging

夏季通过空气对流开窗会适量的散发室内的空气污染，但是冬季节装修完工后，当室内温度低于20℃时，开窗通风去除装修污染的效果便开始大大减弱。当室内温度低于10℃时，所有的装修污染将积存在室内，不再向外释放。即使整日整月地敞开窗户通风，去除装修污染效果不显著。再加上冬季人们本来就很少开窗，要开的话也不太会太久，这就更加的造就了室内污染物的堆积。

In summer, indoor air pollution can be appropriately emitted through air convection window. However, when winter indoor decoration is completed, when indoor temperature is below 20 degrees, the effect of window ventilation and removing decoration pollution will start to weaken. When the indoor temperature is below 10 degrees centigrade, all the decoration pollution will be stored in the room and will no longer be released. Even if all the entire month open the window ventilation, decoration pollution removal effect is not significant. In addition, in winter, people would have rarely opened the window, and the words to open would not be too long, which made the accumulation of indoor pollutants more important.

问题四

Question four

污染物质浓度增加

Increased concentration of contaminants

秋冬季门窗密封比较严密，室内新风量大大降低，而室内装饰材料和家具中释放出的甲醛等有害气体、燃料燃烧后产生的化学物质、吸烟时产生致癌物质，都会在室内不断增加而无法稀释。

In autumn and winter, door and window seal is relatively strict, indoor fresh air volume is greatly reduced, and formaldehyde and other harmful gases released from interior decoration materials and furniture, chemical substances produced after combustion of fuel and carcinogenic substances in smoke will increase continuously indoors, and cannot be diluted.

随着秋冬季气温的不断降低以及暖气的开放，室内温度相对较高，建筑装修材料和家具中的一些有毒有害气体释放增加，而室内通风时间不断减少，使得室内环境中的有毒有害气体难以尽快消散，容易造成污染气体在室内的滞留，而人们为了躲避寒冷在房间内的时间也逐渐增多，室内空气污染的危害也进入了“高危险期”，因此为了家人和自己的健康，冬季室内空气检测治理和相关的措施，就很有必要了。

With the autumn and winter temperatures decreased and the heating of the opening, the indoor temperature is relatively high, the release of some building decoration materials and furniture in the poisonous and harmful gas and increase indoor ventilation time decreasing, the toxic and harmful gas in the indoor environment is dissipated as soon as possible, easy to cause pollution in indoor gas retention, and people in order to escape the cold time in the room has gradually increased, hazards of indoor air pollution has entered a "high risk", so to their family and health, winter indoor air testing management and related measures, it is very necessary.
