篇一:空气污染的危害作文200
This year, with the high speed development of economy in our country, the improve
ment of people's living standards. Pollution have becoming an Increasing Concern in China such as the serious pollution of air, water and soil. the polluted air does great harm to people’s health. The polluted water causes diseases and death. And the polluted soil is harmful for our food. In my opinion, the most urgent problem is air problem for our country Air quality has become a big topic in recent years. Tens of millions of people across China have been forced to cope with high levels of PM2.5- particulate /pəˈtɪkjəlɪt/（微粒） matter smaller than 2.5 micrometers in diameter that can penetrate the lungs and harm the respiratory, cardiovascular, cerebral vascular and nervous systems. Air pollution is not just about sore throats, but really more of a matter of life or death. The harmful effects that smog can have on the human body are one of the top concerns among those who reside in the country’s bigger cities.
Many factors are contributing to the air pollution. The pollution of people’s life, industrial pollution and traffic pollution . First of all, in the life of people, the burning mineral fuel, many harmful gases are emitted in the atmosphere, in addition, decomposition and combustion of Living garbage has also produced a lot of harmful gas. Secondly, the discharge of industrial waste gas is undoubtedly one of the major source of air pollution. With the development of economy, the growth in the number offactories and industrial management is not in place so that a large number of harmful gas is emitted in the air. Finally, a big reason is caused by the automobile
exhaust gas pollution.There are a lot of harmful gases in the exhaust emission of vehicle.
To my view, stiffer laws and regulations must be implemented to check pollution. Industries that release wastes without permission should be heavily fined. Cars should be equipped to minimize the exhaust they release into the air. And the use of plastic bags and disposable meal boxes should be banned. What's more, the media should play an important role in implanting a sense of environmental consciousness into people's mind.
If everybody works toward a common goal of making the environment better, we can create a cleaner and lovelier world for us and for the coming generation.

With the broadcast of <under the dome>, smog,this long-standing environmental problems, become the hot discussion once again.According to some reports,the frequent appearances of smog obscure the clarity of the sky recently.Some people drove slowly on the road because they could not see clearly. They also suffered from many illnesses caused by smog.
Smog is the general expression of various higher-than-permitted
suspended particulate matter (such as PM2.5) in the atmosphere,which express the state of air pollution .It contains fog and haze,both of them are disastrous weather. Fog consists of a large number of tiny water or ice crystals.It’s actually a harmless natural phenomena that makes visibility worse .Haze is air pollution in which is mixed up with dust, smoke and other dry particles. The components that make up haze may have negative effect on people's health, especially for children and the old.
So it’s necessary to find out the reason why leads to smog and work out the resolution.If we trace the cause for smog weather ,the main points are natural causes that include windblown dust and manmade causes which include three aspects.Firstly,china 's air quality standards are rather lax and evaluation factors are limited.Secondly,some enterprises just go for economic interests instead of observing relevant law and regulations.Obsolete equipment、industrial fuel burning and manufacturing operations are high likely to emit much wasted air.Thirdly,across our society ,relevant protection awareness has not built up.Just for the sake of convience to go out,people rely more and more on travelling and working by car while car is the main cause for smog.
To settle this problem,a series of meaures should be taken as follows.Primarily,we should establish a sound control system of smog. Not only can environmental protection departments strengthen air monitor,but government should enact more strict laws and
regulations.Moreover,Reduce pollution sources is the fundamental solution to cut air pollutants. For example,we can reduce the amount of fuel vehicles or close down high polluting enterprises.Developing green and energy-saving energy can lower the emission of smog.Last but not least, People should do personal protection.They need to reduce the time for outdoor sports and pay attention to rest in smog days.Everyone all over the country should take measures to reduce the smog weather. We can use more public transport such as the bus and the underground so that the number of cars will be limited.Also,people should plant more trees. As far as I’m concerned ,if we work together to do such measures ,smog weather will vanish completely and we will get clear and blue sky.

空气中无限的美200字作文
我们常常会说我爱“这种迷人的景色”，实际上就只是说说罢了，我们都没有做到保护环境这一习惯，因此空气会变得很肮脏，使得我们身边的景色都变得慢慢脱臼了。这些都是我们所制造出来的。

照着这样的句子把一年四季写完，就好了。
室内空气污染对人们健康的影响
篇四:空气污染的危害作文200
世界卫生组织已将室内空气污染列为人类健康的十大威胁之一，其严重影响了我们的生活质量。根据中国疾病预防控制中心统计，近年来因室内装修污染而引发的肺癌、白血病、不孕、胎儿畸形、皮肤癌、鼻癌、咽喉癌等病症屡见不鲜，而且室内空气污染引起的全球性的人口发病率和死亡率还在不断攀升。
如何改善室内空气质量已成当下亟待解决的问题。
多年来我国室内空气污染不仅是不争的事实，而且有普遍化和日益严重的趋势。专业检测机构经过测试研究认为，室内装修污染包括化学性污染物、生物性污染物及物理性污染物三大类，危害较大的室内空气化学性污染物主要有：甲醛、苯系物、氡、氨等。
其中甲醛可以引起慢性呼吸道疾病，甚至是致畸、致癌，还可以引起白血病和再生障碍性贫血，会使人昏迷，甚至死亡。这些室内空气污染物严重影响了人类健康，也成为大家共同关注的问题。
调查表明，现代人平均有90%的时间生活和工作在室内，65%的时间在家里。而室内空气污染程度要比室外空气污染程度严重2-5倍，在特殊的情况下，甚至于可以达到100倍之多。
室内空气污染已成为人类健康的“隐形杀手”，去除室内空气污染，提高身体健康水平，已迫在眉睫、刻不容缓。
