1、人与自然-大气污染 现在我们呼吸的空气是被污染的。大气为什么会被污染呢?工厂和汽车的排烟是主要原因。随着亚洲国家工业的迅速发展,人口增加,利用汽车的在增多,大气污染成了深刻地问题。大气污染不管有害于我们的健康,也是全球变暖的原因之一。环境问题需要我们每个人提高意识。下面让我们看一下关于大气污染的现状和对策及造成大气污染的原因。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.Let us s
3、ee 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 state substanc
4、es(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 related environmental probl
5、ems.The shape of the atmospheric pollution occurred not only with gas,and that the individual and air sol small particles and other substances.大气大气污染的原因染的原因汽车,工厂等排出的烟污染空气,这种情形叫大气污染。大气污染的物质包括氮氧化物(NOx),粒子状态浮游物质(SPM),二氧化碳(CO2)等。这些物质是导致全球变暖,酸雨,光化学缝褶的原因。造成大气污染的主要原因是汽车,工厂排出的烟等人为的因素。大气污染是跟我们的日常生活密切相关的环境问题。
6、发生大气污染的形状不光有煤气,还有叫空气溶胶的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,automobile etc discharge

8、e 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 respiratory patients rise of mortal
9、ity.大气大气污染物染物质的种的种类让我们看一下大气污染物质的种类和给环境带来哪些问题。1、氮氧化物(、氮氧化物(NOx)是造成大气污染原因的代表性物质。造成氮氧化物的原因是锅炉,汽车等排出的烟。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的原因。2、浮游粒子状物、浮游粒子状物质(SPM)浮游物质是在空气中浮游的物质,是大气污染的污染物质之一。除了工厂排出的烟,汽车排出的废气等人为因素之外,火山,森林灾害等自然发生的自然灾害也是它的原因之一。浮游粒子状物质是有害于人类健康的大气污染物质,会导致呼吸道患者死亡率的上升。3,and photochemical ok
