篇二：关于空气质量的英语专业术语
关于空气质量的英语专业术语
这两天大家一定都很关注空气质量情况的播报，也许你会好奇空气质量指数到底是根据哪些污染物算出来的？各种等级的污染对我们有哪些危害？下面就来为大家科普下这些基础知识吧：
【关于空气质量的术语】
环境空气 ambient air
指人群、植物、动物和建筑物所暴露的室外空气
空气质量指数 air quality index (AQI)
定量描述空气质量状况的无量纲指数。
空气质量分指数 individual air quality index (IAQI)
单项污染物的空气质量指数。
首要污染物 primary pollutant
AQI大于50时IAQI最大的空气污染物。
超标污染物 non-attainment pollutant
浓度超过国家环境空气质量二级标准的污染物，即IAQI大于100的污染物。
总悬浮颗粒物 total suspended particle (TSP)
指环境空气中空气动力学当量直径小于等于100μm的颗粒物。
颗粒物（粒径小于等于10μm）particulate matter (PM10)
指环境空气中空气动力学当量直径小于等于10μm的颗粒物，也称可吸入颗粒物。
颗粒物（粒径小于等于2.5μm）particulate matter (PM2.5)
指环境空气中空气动力学当量直径小于等于2.5μm的颗粒物，也称细颗粒物。
* 此前我们国家采用的空气质量标准是API (Air Pollution Index)，也就是空气污染指数；但在2012年2月后进行了修订，改为AQI，最重要的一个变化就是加入了PM2.5的监测。
【AQI基于哪些空气污染物】
The AQI level is based on the level of 6 atmospheric pollutants:
① 二氧化硫：sulfur dioxide (SO2)
② 二氧化氮：nitrogen dioxide (NO2)
③ PM10：suspended particulates smaller than 10μm in aerodynamic diameter
④ 一氧化碳：carbon monoxide (CO)
⑤ 臭氧：ozone (O3)
⑥ PM2.5：suspended particulates smaller than 2.5μm in aerodynamic diameter

篇三：空气污染1000字英文论文
Improve Air Quality——Everyone Should Get Involved
Background information:
My neighborhood is a rural area in Nantong City, Jiangsu Province. Almost each family there has a piece of farmland of their own. At the beginning, residents made a living mostly by eating food produced by them and selling extra food. Recently as economy grows, more and more residents have chosen to rent their farmland out to make space for factories, at the same time they can get an opportunity to work in factories. Generally speaking, this area is still in its early stage of industrialization. Just like many other places which have gone through or are undergoing industrialization, my neighborhood also faces the conflict between economic growth and environment protection. In addition, residents there sometimes do activities which damage the environment even without realization due to poor knowledge of the causes of environmental unsustainability. One of the most serious aspects of the environment is the decline in air quality. My neighborhood used to have fresh air, but now smog appears from time to time. So in this report, I am going to focus on air pollution in my neighborhood.
Causes and solutions:
1. Industrial pollution
Just as stated above, my neighborhood is in its early stage of industrialization, so air pollution there must have a close relation with industrial wastes. On the one hand, factories are continuously producing air-borne emissions. Among them, factories such as the rubber factory give out waste gases with an unpleasant smell, which is particularly unbearable to people living nearby. On the other hand, large area of farmland and woods are turned into industrial land, thus causing a weakened function of vegetation purifying air. Although there are many examples that cities go for economic growth in sacrifice of environment and repair the environment after becoming rich, we need not necessarily repeat the model of “pollution first, treatment later” in the course of industrialization. I think we can report those factories to local environmental protection agency, forcing them to release waste gases after treating through legal procedures. We can also use the power of public opinion by posting those factories onto “weibo”.
2. Straw burning
Picture 1(taken in May, 2013)
It is not uncommon to see people burning crop straw in rural area. Such behavior is harmful to both environment and society for the following reasons. First, when burning straw, the three pollution index of sulfur dioxide, nitrogen dioxide and repairable particulate matter in the atmosphere reaches peak, which damages human health. Secondly, straw burning can easily cause fire if there are combustibles around. Thirdly, poor visibility caused by smog leads to more cases of traffic accidents. Last but not least, straw burning can cause ground temperature to rise rapidly, killing beneficial microbes in soil, affecting the full absorption of plant to soil nutrients, decreasing the yield of crop. Actually,
“In Jiangsu Province, the local government has sent supervision teams to all cities to monitor straw burning. Furthermore, in order to extend the scope of the monitoring, the provincial environmental protection agency begun to use remote sensing data to detect locations of fire in straw fields. Unfortunately,
supervision is difficult and to avoid detection, some farmers choose to not
burn straw during daytime but in the evening or on cloudy days.”(Qu, Li,
Wu&Giesy, 2012)
Why do people would like to run the risk of being punished just in order to burn straw? Because young people in a family almost don’t do farming any more, the old and weak members wouldn’t bother to transport heavy straw which is useless to them but very useful if collected and used to generate electricity and methane. To solve this problem, both government and residents should get involved. Local government should set up more straw collection spots so that residents can find the nearest spot to them. Residents can buy the straw returning machine and the bundling machine jointly to minimize the economic burden on each member.
3. Fireworks and firecrackers
Picture 2&3(taken on New Year’s Eve, 2014)
It is Chinese tradition to set off fireworks and firecrackers in celebration of Chinese New Year. Although fireworks and firecrackers can bring us great pleasure, they have also posed a threat to the environment. Just as shown clearly in the picture, the sky is covered by a mist because of fireworks. Fireworks and firecrackers produce smoke and dust that contain various sulfur-coal compounds and other noxious chemicals, which contribute to acid rain and have a bad effect on human respiratory system. On top of that, fireworks contain cancer-leading heavy metals in order to produce brilliant colors. (Hiebert, 2013) Now that fireworks and firecrackers can cause air pollution, we are supposed to think carefully whether we really need them. In some major cities of China, fireworks are prohibited, but in rural area this
problem hasn’t been paid attention to. Although it is of great importance to release related regulations, it’s even more urgent to inform rural residents of the drawbacks of setting off fireworks and firecrackers. If we cannot accept festivals completely without fireworks and firecrackers, maybe we can gather together and watch a firework show instead of each family setting off its own fireworks.
4. Other causes
Picture 4(taken on 4th February, 2014)
There are also many other factors leading to air pollution. For example, some families still use the old stove (picture 4) for cooking, so they sometimes burn their daily rubbish because they think it can not only save energy but also dispose rubbish. Burning waste paper is ok, but some plastic product may produce harmful gases if burnt. Another example is burning briquettes, which can cause sulfur dioxide in the atmosphere to increase. These problems can all be attributed to lack of common sense about air pollution. Therefore, I hope our community organization can popularize related knowledge so that residents reduce, if not stop, their behavior of damaging the environment.
Summary:
In conclusion, environment protection is not an individual activity but need everyone’s participation. As long as every member in our community does their bit, air quality is bound to be improved.
