Haze(雾霾)
The longest distance in the world is that I couldn’t see Chairman Mao even though I am right in front of the Tiananmen!
Haze is a combination of fog(little drops of water) and haze(tiny particles).
I am looking forward to see sky covered with shining stars every night.
And I wish all of you a happy Tombsweeping Day! Thank you for listening
A city in haze is neither beautiful,nor suitable for living. In 1952,the severe fog lasted for 5 days,leading to death of 12,000 people,the majority of victims is children and people with respiratory disease . It took 20 years to solve the haze in London. Now in China, NPC &CPPCC(National Peoples Congress & Chinese Peoples Political Consultative Conference ) determin to solve the haze in 10 years.
90% of the obscure we see in the air is haze. 7years after serious haze,there will be a period that the rate of lung cancer is extreme high. Human’s Physiological structure decides that we are unable to keep PM2.5 away from our lung. 50% of PM2.5 will stay in lung,causing a Variety of diseases.
Not all green plants absorb PM2.5,some even release PM2.5,especially fragrant green plants.
Effective ways to avoid PM2.5 harm
Step 1:Be care of visibility,it’s harmful to you if the visibility is under 5 miles. Step2:Search Air Quality Index first,reduce outdoor exercise if it’s beyond 100. Step3:Wear N95 mask while density of PM2.5 reach 150μg/m3. People with respiratory disease should wear while it’s beyond 75. Step4:Drink more water(not drink),at least 1200ml per day.
Mask
Air Cleaner
Green Plant
Hale Waihona Puke All of them don’t work!
Only N95(a high criteria of mask) mask is effective,while it should be changed regularly.
Immature air-clean technology result in worse air pollution(air cleaner turns out to be pollutant source).
PM:Particulate matter PM 10:Inhalable particles PM 2.5:Particles can be drawn into lung Particle size<2.5μm PM2.5 is a combination of haze and air pollution like SO2,heavy metal,etc.
