Today we stay at home and not go to class. Do you know why? By the way, it is just because of the fog.
Haze? Nanjing and other places of dust is overmuch, combined with the dust and fog, becomes the haze, inhaled into people get lung disease, asthma and other respiratory diseases.
Recently, pm2.5 is close to the extraordinary, in nanjing today at 3 o 'clock in the morning, pm2.5 has reached 466 micrograms of a cubic meters, entered the serious pollution, pm2.5 is one of the "culprit" haze weather. Not just the pm2.5 exceeds bid badly, pm10 has recently started to crazy, 3 a.m. yesterday, pm10 has reached 579 micrograms of a cubic meters, the nanjing the worst pollution index was about to break! In addition, the sky appeared a "mock sun"! Is too much because floats in the sky. If nanjing on October 1, the sky is blue, so today in nanjing will be gray and a piece of the sky.
Fog not only have an effect on the human body, many planes, ships, cars and so on all can't normal travel. Nanjing lukou airport has 53 flights affected by haze on time boot. Many highways have been closed, the highest visibility on the streets of only 10 meters the following, the car travel is very inconvenient. Hundreds of ships to stay in the Yangtze river in zhenjiang. The influence of the fog's really big ah!
We air pollution index of the middle and lower reaches of the Yangtze river has been more than the north, like tianjin, Beijing, hebei and other provinces, cities have been we left behind. The factory in the north is more, to produce a lot of dust, according to the reason for the northern cities should air pollution is the most "powerful", can be in November to December China's worst air index, almost all is our "occupy" in jiangsu province.
Now that the fog is so terrible, we should also consider what to do! 1, when faced with heavy fog, the first thing to hide the fog haze. Haze days don't go out as far as possible, don't get up early to exercise more. 2, mask is fog out of necessity. Will always wearing surgical masks, but not always wearing a mask, only on the road, a lot of bacteria such as hospital, pm2.5 wear a lot of place, at other times, try to put in my pocket.
This is the fog haze, a great influence on our body, we must learn to prevent it! That is why our school classes.
今天我們同學都留在家裡不去上課。你們知道為什麼嗎?對了，就是因為霧霾。
霧霾是什麼呢?南京等地的灰塵過多，而霧跟這些灰塵相結合，就變成了霾，人大量吸入會得肺病、哮喘等呼吸道疾病。
最近，南京的pm2.5接近爆表，到了今天凌晨3點，pm2.5已經達到了466微克一立方米，進入了嚴重污染，pm2.5是霧霾天氣的“罪魁禍首”之一。不僅僅是pm2.5超標嚴重，pm10最近也開始瘋狂起來，昨天凌晨3點，pm10已經達到了579微克一立方米，這項指標就快要破南京最差污染了!而且，天上還出現了一個“幻日”!就是因為天空中的漂浮物過多而形成的。如果說10月1日的南京的天空是湛藍的，那么今天南京的天空將是灰濛濛地一片。
不僅霧霾對人體有影響，許多飛機、船隻、汽車等都不能正常出行。南京祿口機場已有53個航班受霧霾影響不能準點開機。許多條高速公路都已經關閉，街頭的最高能見度才僅僅10米即以下，這讓汽車出行非常不方便。數百隻船隻停留在長江鎮江段。霧霾的影響可真大呀!
我們長江中下游的空氣污染指數已經超過了北方，像天津、北京、河北等省、市都已經被我們落在後面。北方的工廠較多，會排出很多的灰塵，按道理來講北方城市應該空氣污染是最“強”的，可11月到12月中國的空氣最差指數，幾乎全部是我們江蘇“占領”的。
既然霧霾這么可怕，我們也應該想想該怎么辦吧!1、當遇到濃霧天氣，首先要躲霧霾。霧霾天儘量不要出門，更不要早起鍛鍊。2、口罩是霧天外出的必需品。要常帶口罩，但不能常戴口罩，只有在馬路上、醫院裡等病菌很多，pm2.5很多的地方戴，其他時候，儘量放在口袋裡。
這就是霧霾，對我們人體影響很大，我們要學會預防它喔!這也就是我們學校為什麼停課的原因了。
