In the film Private Custom , we make apologies to the sun, for we cant see it clearly because of the haze; we make apologies to polluted river- the mother who nurtures us, for it is stink because of contamination and it may be unwilling to continue to nurture us; we make apologies to the soil, for we are so greedy of extraction of oil that the soil is infertile“PM2.5”and “Haze” have already been familiar to us, especially in Beijing and Nanjing. Living in Nanjing, I experienced the haze and had a deep thought about it. So, making use of the opportunity, I will talk it through. Key Words : Haze; Nanjing; harm; reason; solutions1. Introduction The longest distance in the world is that I couldnt see Chairman Mao even though I am right in front of the Tiananmen! Nowadays,“PM2.5”and “Haze” have already been familiar to us, especially in Beijing and Nanjing. One of the most popular iPad apps in Beijing at present is China Air Pollution Index. The app is both addictive and disturbing. I checked the numbers and discovered that the AQ level, which measures fine particulates that are especially dangerous, was 250 about five times the level deemed safe. Living in Nanjing, I experienced the haze. At that time, all the middle school students had two days off to keep away from the haze. However, we university students had classes as usual. Maybe we are stronger than middle school students, but even they are kept indoors, it is hard to escape from the harm of haze. So, lets talk about haze in the following aspect. The definition of haze WHO guidelines say average concentrations of the tiniest pollution particles - called PM2.5 - should be no more than 25 microgrammes per cubic metre. Air is unhealthy above 100 microgrammes and at 300, all children and elderly people should remain indoors. With the deterioration of air quality, haze got worse and worse. Many areas incorporated haze into the fog together as weather warning forecasting. In fact, there is a big difference between fog and haze in some ways. For example: fog occurs when the air is humid, while haze occurs when the air is relatively dry, the relative air humidity is usually below 60%. Its formation is due to a large number of very fine uniform floating dust particles, soot, salt, etc. in the air, causing the effective horizontal visibility less than 10KM air turbidity. Diurnal variation haze obscured. When there is no large change in the air mass, haze lasts for a long time, sometimes over more than 10 days. Because the haze, mist, dust storms, blowing sand, dust, smoke and other weather phenomena are caused by floating in the air and a lot of very fine dust or smoke particles , etc. resulting in effective horizontal visibility is less than 10KM. So sometimes it is difficult for weather professionals to distinguish them. In order to draw the right conclusions, weather professionals must combined the weather background, sky conditions, air humidity, odor and color satellite monitoring and other factors to make a comprehensive analysis, but sometimes fog and haze can interchange . The harm of haze The haze will affect not only health of people but also the economic, as well as the future of China. First, once inhaled, the tiny particles can make people more vulnerable to respiratory infections, as well as leading to increased mortality from lung cancer and heart disease. We all know that losing a family member is how sorrowful, so haze may destroy not only a person, butalso a family. Second, a number of foreigners wont go to China for travelling because of haze, which will bring a loss to our economic. Third, the decline of economic will in turn weaken national power. After all, economic decides politics and culture. In this way, it will be difficult for us to make China Dream come true. Fog and haze are “ killer “ for patients with cardiovascular disease, especially for those who with respiratory and cardiovascular diseases, the elderly. They had better not go out, nor do morning exercises, otherwise, it may induce the disease, or a heart attack, even causing life-threatening. Experts point out that the reason why fog
