in the past few decades, our earth has changed a lot, but to the bad direction. among these changes, the air pollutions resulting from a huge number of automobiles and coal-burning is almost the severest. the severe air pollution alarms humans of the heavy load we have exerted on earth by our insatiable production and usage of automobiles. however, with the deepening of urbanization, more cars are needed, which will make the air pollution worse. therefore, the following actions should be taken. first, we should apply the most cutting-edge technologies in order to adopt new forms of energy as substitutes for fossil fuels. second, try hard to develop possible transportation means, which are enviromental friendly. so that the citizens can reduce the dependence on cars. in short, our humans should take responsibilities for the air pollution and have to find ways to solve this problem.

在过去的几十年中，我们的地球发生了很大变化，但是是往坏的方向。在这些变化中，大量汽车和煤燃烧产生的空气污染是最为严重的。严重的空气污染警告人类，我们无休止的的生产和使用汽车给我们的地球带来了沉重的负荷。然而，随着城市化的加深，汽车的需求量也越大，这会导致空气污染更严重。因此，我们应该采取以下行动。首先，我们应该运用最尖端的技术，以新型能源作为化石燃料的替代品。其次，努力寻找可能的环境友好型交通方式。这样城市居民就可以减少对汽车的依赖。简而言之，人类应该承担空气污染的责任，寻找解决这一问题的方法。

空气污染的作文篇2

大家都知道我们应该减少空气污染，但是很多人都只是嘴上说说，根本不去实践!你们知道空气污染的危害吗，你们知道如果不减少空气污染我们将要面临的是怎样的未来吗?

我的家乡——大连，是座美丽的城市。听爸爸说，以前的大连是个环境优美，空气清新的城市，空气中到处弥漫着海洋的味道，夏季的雨后，经常能看到美丽的彩虹如七彩桥一般挂在天边。我在家里看到过很多爸爸小时候的生活照片，在照片的背景中，我看到天空万里无云，马路上很少有各式各样的机动车，那时人们的交通工具主要就是靠公共汽车，环境确实比现在好多了。

现在家乡的车辆增多了，每天都有成千上万辆汽车行驶在马路上，这些汽车排放的尾气，不仅破坏了环境，同时也危害了人们的身体健康。我听广播说，汽车排放出的尾气使我们的城市变暖了，而且这些气体悬浮在城市上空很难消散，汽车尾气中还有大量的一氧化碳和二氧化碳，这些气体都是对人体有伤害的，如果被人们吸到体内，就会引起肺部的很多疾病呢。怪不得每天早上我上学的时候，天空中总是灰蒙蒙的一片，很难看到早上初升的太阳，雨后的天空中也没有彩虹，湛蓝深远的天空消失不见了，就连叽叽喳喳的小鸟也不愿意来到这样的地方，只有在儿歌中才有“太阳当空照，花儿对我笑，小鸟说……”的景象。

你知道吗，大连她在哭泣，她哭人们这样伤害她，破坏她，把她原本美丽的面貌变成了这样丑陋。我建议有车的家庭要减少车辆的使用，尽量步行或坐公交车，这样才能让我们的城市空气更清新。

我们大家都应该清楚知道空气污染的危害，然后赶紧行动起来，保护我们生存的环境，让空气污染不要伤害我们的家园!保护我们的家，从你我做起，从现在做起，从身边的小事赶紧做起!

空气污染的作文篇3

health, surrounded by, smog, anything but, gases, impurities, absorb, poisonous, try hard, blacked out.

we all know that clean air is important to good health. wherever you go and whatever you do, you are always surrounded by a sea of gases that we call air.if there are impurities in the air, they may be absorbed by our bodies and make us ill.

we need clean air, but unfortunately, air pollution is globally present, especially in cities.many large cities are anything but pollution-free. our cities have many factories, which we need to make food, clothing and other things.every year these factories pour millions upon millions of tons of smog into air.

power plants and houses that burn coal add greatly to air pollution. besides, there are more cars in cities now.once out on the streets, they will take in fresh air and replace it with poisonous gases.our country is trying hard to prevent and control air pollution. as long as every citizen also realizes its importance and makes join efforts, the day will e soon when people will take in only clean air.

then, the sunlight will no longer be blackened out by smoke and soot.

空气污染的作文篇4

所谓“大气污染”是指有害物质进入大气，对人类和生物造成危害的现象。如果对它不加以控制和防治，将严重的破坏生态系统和人类生存条件。

大气污染有的是由于森林火灾、火山爆发等自然因素造成的；有的则是由汽车尾气、工业废气、烟尘、爆炸等人为因素造成的，其中人为因素对大气的污染是主要的，尤其是现代交通运输和工业生产对城市大气造成的污染更为严重。因此人们对大气污染问题越来越关切。

造成大气污染的物质有：一氧化炭co、二氧化硫so2、一氧化氮no、臭氧o3以及烟尘、盐粒、花粉、细菌、苞子等。

距地面几十米的近地面层大气，是人类和生物的生存空间。这一层空气质量的好坏直接影响着人类的生产和生活。近年来，由于交通运输业的发展，排放出的大量汽车尾气与空气中的一些物质成分发生化学反应，生成对人体十分有害的一氧化氮、臭氧、乙醛等新物质。

悬浮在大气中的各种气溶胶粒子，按其大小可分为降尘和飘尘。其中降尘的`粒子较大，直径大于10微米，它的自然沉降率较快。它与人类支气管炎的死亡率和农业减产有很大关系；飘尘粒子较小，直径一般在0.1—1.0微米。其自然沉降率很小，故悬浮在大气中的生命史较长。随着粒子的减小有毒元素的浓度将增加。通常小于0.3微米的飘尘能吸入肺泡，如长期积累，会损害呼吸机能，引起哮喘、肺气肿、矽肺和肺癌等不治之症。由于飘尘的污染期长和毒性强，因此它的危害性大。当大气中气溶胶粒子增加到一定程度以后，就会出现烟雾弥漫，能见度降低，太阳辐射减弱等现象。

近地面层大气污染程度与气象条件密切相关，存在着明显的季节变化和日变化。一般冬季的早晨和傍晚在无风的天气条件下空气污染最为严重。夏季由于空气层结不稳定，污染物易向高空扩散，因此一般污染不会太严重。
