雾霾的英语演讲稿 篇1
Shanghai residents breathed the most polluted air they had seen in two months on Wednesday as weak cold air from the north brought pollutants to the Yangtze River Delta.
But clean air is expected on Thursday thanks to another round of cold air, forecasters said.
Seasonal factors played an important role as winter is the high pollution season, and straw burning in nearby provinces also contributed to the pollution, experts said.
Shanghai's air quality index, a new air quality reporting system that monitors sulfur dioxide, nitrogen dioxide, carbon monoxide, ozone, PM10 and PM2.5, reached 254 by 7 pm on Wednesday.
The figure, which indicated the air had reached the level of heavy pollution, was the highest seen since the index was introduced two months ago, according to the Shanghai Environmental Monitoring Center.
Shanghai's hourly density of PM2.5, air particles smaller than 2.5 microns, also reached 250 micrograms per cubic meter by 10 am, while the reading was only 60 micrograms per cubic meter early Tuesday morning.
The heavy pollution in the eastern metropolis followed thick air pollution in Beijing over the weekend. Beijing's density of PM2.5 broke the record since the municipality began publishing the data in early 20xx as its figure went higher than 900 micrograms per cubic meter in several districts of the city on Saturday.
Lin Chenyan, a forecaster with Shanghai Environmental Monitoring Center, said the cold front brought in airborne pollutants from the north.
"The cold snap is like a broom sweeping down all the way to Shanghai, and it brings the dust here," said Lin, adding that atmospheric motion sometimes causes trouble such as that.
Before arriving in Shanghai, the pollutants had left some of Shanghai's neighboring provinces shrouded in smog and fog.
Fifty out of the 72 monitoring stations in Jiangsu province reported medium to heavy pollution on Monday evening, according to Zhang Xiangzhi, deputy director of the Jiangsu Environmental Monitoring Center.
Yang Xin, a professor with Fudan University's department of environmental science and engineering who specializes in atmospheric particulates, said seasonal influences explain the record-breaking data in both Beijing and Shanghai.
"Take Shanghai as an example. It just celebrated its cleanest summer in 20xx - sea breeze from the southeast is helpful in diluting pollutants in the air. However, the monsoons coming from the northwest in the winter usually bring dirty air from the north," Yang said.
Agricultural straw burning in nearby areas also contributed to part of Shanghai's PM2.5 reading, according to Wang Lin, a researcher at Fudan University's Department of Environmental Science and Engineering.
"But it's hard for the Shanghai government to prohibit farmers in the neighboring regions from doing so," Wang said.
According to Lin, the forecaster, Shanghai's air was set to improve on Wednesday night and early Thursday morning. The next wave of cold air is much cleaner because of the clearing of air pollution in the north.

With the broadcast of smog,this long-standing environmental problems,become the hot discussion once again.According to some reports,the frequent appearances of smog obscure the clarity of the sky recently.Some people drove slowly on the road because they could not see clearly. They also suffered from many illnesses caused by smog.
Smog is the general expression of various higher-than-permitted suspended particulate matter (such as PM2.5) in the atmosphere,which express the state of air pollution .It contains fog and haze,both of them are disastrous weather. Fog consists of a large number of tiny water or ice crystals.It’s actually a harmless natural phenomena that makes visibility worse .Haze is air pollution in which is mixed up with dust, smoke and other dry particles. The components that make up haze may have negative effect on people's health, especially for children and the old.
So it’s necessary to find out the reason why leads to smog and work out the resolution.If we trace the cause for smog weather ,the main points are natural causes that include windblown dust and manmade causes which include three aspects.Firstly,china 's air quality standards are rather lax and evaluation factors are limited.Secondly,some enterprises just go for economic interests instead of observing relevant law and regulations

Our country many cities have produced fog, the visibility is very low, so this time the traffic accident rate increases, we haven"t got the security guarantee.
Today, my home is also suffered heavy fog, the window of white, what also can"t see. My home is fog, the air quality is greatly decreased, in order to prevent the body health must wear a face mask to go out.
Today I walk on my way to school, the hateful haze let I almost hit against the tree. Pedestrians in a hurry to walk, large and small are wearing masks. Car kept honking, like to the accompaniment of dust, mist in the headlights, fog haze of dust in the dancing joyfully, from automobile exhaust vent curling into the sky, more than a piece of tail gas, is more than a haze, our safety is more dangerous.
Sky is not blue, trees are not green, white cloud is away, the culprit is the human oneself! Human ah! Return the previous green homes to us!
