1、人与自然-大气污染第1页 现在我们呼吸空气是被污染。大气为何会被污染呢? 工厂和汽车排烟是主要原因。伴随亚洲国家工业快速发展，人口增加，利用汽车在增多，大气污染成了深刻地问题。大气污染不论有害于我们健康，也是全球变暖原因之一。环境问题需要我们每个人提升意识。下面让我们看一下关于大气污染现实状况和对策及造成大气污染原因。 Now the air we breathe is polluted. Why was the atmosphere pollution? Factories and automobile exhaust are the major reasons. With the rapi

2、d development of Asian country industry, the increase of population, the increasing, with auto in atmospheric pollution became profoundly problem. Air pollution whether harmful to our health, is also one of the reasons of global warming. Environmental problems need every one of us raise awareness. L

3、et us see about the present situation of air pollution and countermeasures and cause air pollution causes.Air pollution causesCars, factories and such exhaust smoke pollute the air, this kind of situation that air pollution. Atmospheric pollution material including nitrogen oxides (NOx), particle st

4、ate substances (SPM) zooplankton, carbon dioxide (CO2), etc. These substances are causing global warming, acid rain, photochemical tuck reasons. If atmospheric pollution is the main reason of the cars, factories discharge of smoke artificial factors. Air pollution is with our daily life closely rela

5、ted environmental problems. The shape of the atmospheric pollution occurred not only with gas, and that the individual and air sol small particles and other substances.第2页第3页大气污染原因汽车，工厂等排出烟污染空气，这种情形叫大气污染。大气污染物质包含氮氧化物(NOx)，粒子状态浮游物质(SPM)，二氧化碳(CO2)等。这些物质是造成全球变暖，酸雨，光化学缝褶原因。造成大气污染主要原因是汽车，工厂排出烟等人为原因。大气污染是

6、跟我们日常生活亲密相关环境问题。发生大气污染形状不光有煤气，还有叫空气溶胶个体和小颗粒等物质。Atmospheric pollutant kindsLet us see atmospheric pollutant kinds and give environment bring which problems.1, nitrogen oxide (NOx)Is the representative if atmospheric pollution causes substance. The reason is caused by nitrogen oxides of boiler, automo

7、bile etc discharge smoke. This kind of smoke after burning in the air as nitric oxide in line, air become nitrogen dioxide. Nitric oxide is the reason causing acid rain.2, floating particle shape material (SPM)Material is in air zooplankton floating substance, is one of the atmospheric pollution of

8、pollution. In addition, the smoke from factory car emissions, outside of man-made factors such as volcano, forest disasters occur naturally natural disaster is also one of the reasons it. Floating particle shape material is harmful to human health of atmospheric pollution substances, can cause respi

9、ratory patients rise of mortality.第4页 第5页大气污染物质种类让我们看一下大气污染物质种类和给环境带来哪些问题。1、氮氧化物（NOx)是造成大气污染原因代表性物质。造成氮氧化物原因是锅炉，汽车等排出烟。这种烟燃烧后作为一氧化氮排到空气中，在空气中成为二氧化氮。一氧化氮是造成酸雨原因。2、浮游粒子状物质(SPM)浮游物质是在空气中浮游物质，是大气污染污染物质之一。除了工厂排出烟，汽车排出废气等人为原因之外，火山，森林灾害等自然发生自然灾害也是它原因之一。浮游粒子状物质是有害于人类健康大气污染物质，会造成呼吸道患者死亡率上升。3 ,and photochemic

10、al okindanto (Ox)Photochemical cars, factories, etc okindanto is the nitrogen oxides and hydrocarbon discharge atmospheric pollution substances such as with the suns ultraviolet ray to human body produces chemical reaction, the effects of atmospheric pollution substances, is why tuck photochemical.

11、When okindanto high concentration of chemical when can lead to eyes, throat uncomfortable.4, sulfur dioxide (SO2) sulfonylureasSo2 is coal, oil burning sulfonylureas when atmospheric pollution produced. Characteristics of sulfur dioxide like an egg sulfonylureas when the smell of rotting out. The on

12、set of pollution caused asthma reason is caused by sulfur dioxide sulfonylureas atmospheric pollution.5, carbon monoxide (CO)Carbon monoxide is incomplete combustion by oil caused insipidity, odourless, colorless, no stimulation atmosphere pollutants. Carbon monoxide is very terrible atmospheric pol

13、lutants, if absorbed a lot of carbon monoxide can lead to death.第6页第7页3、光化学okindanto(Ox)光化学okindanto是汽车，工厂等排出氮氧化物和烃类等大气污染物质与太阳紫外线发生化学反应，给人体带来影响大气污染物质，也是光化学缝褶原因。当光化学okindanto浓度高时候会造成眼睛，咽喉不舒适。4、二氧化硫磺(SO2)二氧化硫磺是煤，石油燃烧时候所产生大气污染。二氧化硫磺特征像鸡蛋腐烂时散发气味。公害引发哮喘病发病原因之一是由二氧化硫磺引发大气污染5、一氧化碳(CO)一氧化碳是由石油不完全燃烧引发无味，无臭，无

14、色，无刺激大气污染物质。一氧化碳是很可怕大气污染物质，要是吸收了大量一氧化碳会造成死亡。Atmospheric pollution situationAlong with the economical development, also caused serious air pollution. Countries also begin to pay close attention to the problem, and taken the relevant measures. Some countries have made about air pollution regulations a

15、nd rules, and get substantially improved. But we are facing new problems. The increase of the car from The Times, use the automobile mobile caused the increase of atmospheric pollution, waste in deepened.Improve the atmospheric pollutionIn recent years, various countries to improve the air pollution

16、 in take measures. But around the atmospheric pollution, we still have a lot of problems cannot be resolved from completely improve, there is a great distance. The world watches the atmospheric pollution caused by global warming. If we paid little attention from everyday life to improving under atmo

17、spheric pollution, will help. What we can do said under some energy saving measures.第8页第9页大气污染情况伴随经济发展，也造成严重大气污染。各个国家也开始关注了这个问题，并采取了相关办法。有国家制订了关于大气污染要求和规则，而且得到了大幅度改进。但我们面临着新问题。因汽车增加，使用汽车移动次数增多，废气引发大气污染在加深。改进大气污染近年来，各个国家为改进大气污染在采取各项办法。但围绕大气污染，我们还有很多问题未能得到处理，离完全改进还有很大距离。世界在关注由大气污染引发全球变暖问题。要是我们从日常生活中稍微

18、注意以下，会对改进大气污染有帮助。下面说一下我们能做到一些节能办法。1, energy savingNurturance was out of the room to turn off the lights habit. Although this is the simple, but daily life starts from things, this is very important.2, standby power cutsAlways turned off the TV, tape recorder, etc on standby power supply.3, water-savingWash, rinse your mouth off faucet when. Shower when also careful not to stay open faucet. We can do water saving many methods, as l
