【新唐人2011年12月7日讯】这几天北京出现严重大雾的天气，能见度低到不足200尺，造成班机严重延误，另外，有好几条高速公路也被迫封闭，甚至连北京的空气品质都被测出“有毒害”。
北京气象台又再度发布大雾特报，很多地方能见度不足50公尺，部分高速公路封闭，连机场都因为大雾影响，延误取消的航班多达390班。
根据北京市环保监测中心提供的信息，3号中午到4号中午，北京市空气污染指数为80，空气品质为良。从4号中午到5号中午，空气污染指数为193，空气品质属于轻度污染，但污染物浓度相比4号下午和夜间有所下降。
然而，美国驻北京大使馆公布最新PM2.5空气污染指数，结果显示PM2.5浓度达522，显示空气污染超出最高污染指数500，超过可忍受指数（Beyond Index），属于“糟糕透顶”级（Crazy bad）。
空气品质指数(AQI) 150-200为“不健康”﹔200-300为“极不健康”﹔300-500为“有毒害”。
不少大陆网友表示，北京的空气污染“再度爆表”，北京市民野靖春无奈表示，北京的空气越来越糟。
北京市民野靖春：“北京空气不好啊，灰濛濛的市里边五环以里，基本上看不到什么蓝天，在北京住了五十年了，小时候在外边数星星，现在根本看不见星星，现在在这里生存，我也不能离开这个地方，就听天由命吧！所以只能这样。”
北京空气质量差，民众生活在灰色天空下也只能听天由命，另外一位北京市民对此也表示无奈。
北京市民周中：“我感觉比30年前差很多，因为那个时候年轻，我今年48岁，我小的时候空气很清新，现在就是很混浊，污浊吧，质量很差，平时（天空）都是灰的，今天又是大雾弥漫，经常是这样，因为我们都习惯了，都成了吸尘器，无所谓了。”
《央视》记者芮成钢也在他的微博上写着，今天北京的空气怎么了？一进楼道还以为是哪里着火了，走到地下室也是这个味道，一出门才知道到处如此，嗓子开始痛。
北京的空气无法给民众一个健康的生活环境，民众只能自保。尽量减少外出，即使出门也尽量戴口罩。
据报导，淘宝商城一家商户仅12月4号就卖出3万多个口罩，比前两周平均销售量翻了3倍，其中有两万多个是被北京地区用户买走。
天气寒冷加上严重的空气污染，专家说，雾霾天气中吸附了大量的尘埃、污染物和细菌，对人体呼吸道有害。
呼吸科专家王蕾：“在这种雾霾天气，除了水汽之外，还含有一些粉尘、二氧化硫或者是氮硫化物这些成分，像这些如果吸入身体就会对身体有害，尤其是对呼吸系统的伤害会比较大。”
有媒体说，为了躲避地沟油，我们可以在家吃饭﹔为了喝口干净水，我们可以购买各种净水器﹔为了不摄入三聚氰胺，我们不喝牛奶﹔但这年头，喝西北风，也可能会中毒。

Heavy Fog Surrounds Beijing, Causing Unrest Among Residents
Recently, severe fog conditions appeared in Beijing, with visibility less than 200 feet, causing severe flight delays. In addition, many expressways have been shut down. The air quality was tested and found to be “toxic”.
Severe fog conditions were again reported in Beijing with visibility less than 50m. Some highways were closed down and more than 390 flights were canceled.
According to information from Beijing City Environmental Monitoring Center, the Beijing air pollution index was 80 around 3-4pm, which is considered good. From 4-5pm, the pollution index was 193, which means a low level of pollution. pollution levels went down past 4pm.
However, the PM2.5 air pollution index published by the U.S. embassy shows the PM2.5 density reached 522, exceeding the maximum tolerable value of 500. The air pollution is beyond index, or terrible.
In air quality index (AGI) measurements, 150-200 means “unhealthy”; 200-300 means “very unhealthy”; 300-500 means “toxic”.
Many mainland netizens expressed that the Beijing air pollution again “busted the scope.” Resident Ye Jingchun expressed that the air in Beijing is getting worse.
Ye Jingchun, “Air is Beijing is bad, inside the city the blue sky is not visible. (I) lived in Beijing for 50 years and used to count stars when I was young, now you can’t see stars anymore. Living here, I can’t even leave this place, can only follow my fate! That’s all I can do.”
Living under a gray sky, residents can only accept the reality. Another Beijing resident also expressed helplessness.
Beijing resident Zhou Zhong, “I feel it’s much worse than 30 years ago, I was young then, now I’m 48. The air was fresh when I was young, now it’s cloudy, dirty.
Normally (sky) is gray, today it was very foggy, it’s frequently like this.
Because we are used to it, our lungs just like a vacuum cleaner, nothing we could do…”
CCTV reporter Rui Chenggang wrote on his micro-blog, “what’s with the air in Beijing today? In the hallway, I thought something was burning, the basement has the same smell. After going outside, I realized everywhere was like this,
my throat is starting to hurt.”
Unable to change the air quality, residents can only try to protect themselves.
Try to stay indoors and wear masks when going outside.
According to a report, a seller on the online shopping site Taobao, sold 30,000 masks on Dec 4, a twofold increase over a two week average. More than 20,000 were bought by Beijing residents.
Experts warn that cold weather combined with severe air pollution can cause absorption of dust, pollutants and bacteria harmful to the human respiratory tract.
Respiratory Expert Wang Lei, “During such foggy weather, in addition to water vapor, there is dust, sulfur dioxide, and other sulfur chemicals (in the air), they are harmful if inhaled, especially for the respiratory system.”
The media said to avoid eating waste oil, we can eat at home; to drink clean water, we can buy a water purifier; to avoid melamine, we don’t drink milk;
now even breathing might get you poisoned.
