篇二:环境污染

环境污染

环境污染是指人类直接或间接地向环境排放超过其自净能力的物质或能量,从而使环境的质量降低,对人类的生存与发展、生态系统和财产造成不利影响的现象。具体包括:水污染、大气污染、噪声污染、放射性污染等。水污染是指水体因某种物质的介入,而导致其化学、物理、生物或者放射性污染等方面特性的改变,从而影响水的有效利用,危害人体健康或者破坏生态环境,造成水质恶化的现象。大气污染是指空气中污染物的浓度达到有害程度,以致破坏生态系统和人类正常生存和发展的条件,对人和生物造成危害的现象。噪声污染是指所产生的环境噪声超过国家规定的环境噪声排放标准,并干扰他人正常工作、学习、生活的现象。放射性污染是指由于人类活动造成物料、人体、场所、环境介质表面或者内部出现超过国家标准的放射性物质或者射线。例如,超过国家和地方政府制定的排放污染物的标准,超种类、超量、超浓度排放污染物;未采取防止溢流和渗漏措施而装载运输油类或者有毒货物致使货物 落水造成水污染;非法向大气中排放有毒有害物质,造成大气污染事故,等等。

随着科学技术水平的发展和人民生活水平的提高,环境污染也在增加,特别是在发展中国家。 环境污染问题越来越成为世界各个国家的共同课题之一。

由于人们对工业高度发达的负面影响预料不够,预防不利,导致了全球性的 三大危机 : 资源短缺、环境污染、生态破坏 . 人类不断的向环境排放污染物质。但由于大气、水、土壤等的扩散、稀释、氧化还原、生物降解等的作用。污染物质的浓度和毒性会自然降低,这种现象叫做 环境自净 。如果排放的物质超过了环境的自净能力,环境质量就会发生不良变化,危害人类健康和生存,这就发生了环境污染 。

环境污染会降低生物生产量,加剧环境破坏。

环境污染源主要有以下几方面:

1)工厂排出的废烟、废气、废水、废渣和噪音;

2)人们生活中排出的废烟、废气、噪音、赃水、垃圾;

3)交通工具(所有的燃油车辆、轮船、飞机等)排出的废气和噪音;

4)大量使用化肥、杀虫剂、除草剂等化学物质的农田灌溉后流出的水。

5)矿山废水、废渣。

篇三:噪声与人类健康

噪声与人类健康

教学目标:知道噪声产生的原因和途径。

知道噪声对人类有哪些危害。

知道减少噪声有那些措施。

教学重难点:噪声产生的原因。

教学过程:

1、导入

同学们,我们的生活离不开声音,各种各样的声音使世界充满生机,使我们的生活丰富多彩。美妙的乐声给人们带来了无穷的欢乐和享受。但是,刺耳的噪声却严重危害着人类的健康。揭题——噪声与人类健康。

2、新授

(1)噪声引起的危害有哪些?

它引起头痛、心慌、全身乏力、听力受损,还有心血管系统、神经系统、消化系统等方面的疾病,甚至导致胎儿畸形。噪声已经成为世界第一公害,被称为“无形杀手”。

(2)噪声是怎样产生的呢?

噪声的产生主要分为交通噪声、工业噪声、建筑噪声和生活噪声。

机动车辆、飞机、火车和轮船等交通工具在运行时发出的声音,称为交通噪声。其中飞机的噪声最大。

(3)工业噪声是指工矿企业在生产过程中因机械振动、摩擦、撞击以及气流振动而产生的嘈杂声音。工业噪声主要来自机器和高速设备。

(4)建筑工地上要使用各种动力机械,要进行挖掘、打夯、搅拌和运输材料设备,也会产生大量噪声,称为建筑噪声。

(5)生活噪声是街道、商场、文化娱乐场所(如电影院、剧院、体育场)以及建筑物内各种人群活动及生活设施所产生的声音。

(6)噪声的强弱大小是用“分贝”来表示的。分贝数越小表示环境越安静。我们通常谈话的声音是30—40分贝。

当噪声超过85分贝,长期可使听力受损,超过120分贝,听力较快受损,甚至耳聋。

3、小结。

为了有一个安静、舒适的环境,我们必须设法制服噪声这个“都市罪犯”。我国已经颁布事实了《中华人民共和国环境噪声污染防止法》,加强了噪声的管理和防治。同学们,让我们一起努力,制服噪声这个“恶魔”,使我们的家园更安宁!

4、作业。

(1)调查你所在地区的噪声的怎样产生的?

(2)调查你所在地区为减少噪声采取了哪些措施?

(3)开一个讨论会,谈谈你对减少噪声的看法。

篇四:保护环境的作文400字

保护环境的作文400字

拉开窗帘,看见尘灰漫天飞舞,一粒粒沙尘打的窗户“啪,啪”响,白色垃圾费的满天都是,好似要吞噬整个世界,天空变成了灰暗色,无任何生机……

溪流旁,工厂不断地排放污水,废气;树林里,工人们无休无止地砍伐着树木;,汽车不断地排放尾气……

难道我们就应该这样对待我们赖以生存的环境吗?不,保护环境,应从自我做起,从身边的小事做起!

可现在很多人来却意识不到自己的错误的行为。

例如:出门时不知道随手关灯;吸收式,用水太多,放音乐时声音太大;经常用一次性的东西;破坏树木……节约,是中华传统美德,我们应该节约用水、用电;节约用塑料袋;不用泡沫纸做的饭盒;不用一次性筷子,一次性勺子等。保护环境,是人人都应该做的事情,我们应该多植树,不破坏树木;少用塑料袋,尽量将环保袋代替塑料袋;拒绝噪音污染;不随手扔垃圾;不随地吐痰;垃圾应该分类安置;废弃的电池不要随点乱扔;不要践踏草坪;不随便摘花等。

噪音污染作文

人类呀!快点醒悟吧!试想,如果没有了树木,那么会带来泥石流、旱灾、洪水等自然灾害,灰尘就会占据天空,许多人就会流离失所;是想,如果不断的排放废气,臭氧层的洞就会扩大,紫外线就会灼伤人类的皮肤,不仅会晒死山上的树木,还会是鸟儿没有了家,害虫没有了天敌,它们会吃掉农夫的庄稼,人类没有了粮食就会灭亡;试想,如果总是随地乱扔垃圾,那我们的城市就会成为一个垃圾堆,我们的生活也就不会这么舒适;试想,如果不节约用塑料袋,那么现在天空上就会飞舞着很多白色垃圾,我们的城市,会成为什么样的景象?

我想要呼吁大家,爱护环境,保护我们赖以生存的家园!

篇五:英语作文~~环境污染

The environment is everything around us,for example,air,water,animals,plants,buildings and so on.They all affect us in many ways and closely related to our lives.People can't live without the environment. Everybody needs to breathe air,drink water and eat food every day.We burn coal to keep warm,and we use wood to make paper.As a result,we become the part of the environment. The environment has been getting wores and wores for many years.We have been upgrading our living standard, meanwhile the environment has been polluted.Somke form factory chimneys pollutesthe air.Machines and engines make noises that annoy us constantly.Animals are homeless because the forcests are decreasing every minute.Streets are crowded with people and vehicles.The environment painful for us to live in it now.So it's time to solve those problems.

Fortunately,it isn't too late to correct our mistake.People are coming to realiza the importance of the environment.We have begun to try our best to improve it.Laws are being made dealing with air, water and noise pollution.The river be bright,the sky will be clear,the flowers will be beautiful,and the sunbeam will be dazzling and pretty.We believe that we wil be able to save our environment and live in a better world

环境围绕我们身边,例如:空气、水、动物、建筑等。它们从各个方面影响着我们的生活,与我们的生活密切相关,人们离开环境就无法生存。每人每天都要呼吸、喝水和吃东西。我们少煤取暖、用木材造纸。结果,我们也成为环境的一部分。

很多年以来,环境日益恶化。我们在提高生活水平的同时,也在导致环境污染。从工厂烟囱里冒出来的烟污染空气;机器和引擎经常发出恼人的噪音。因为森林每分钟都在减少,使动物们无家可归。街道上挤满了人和车辆。环境在我们的生活中是最重要的,但是现在它已经让人们讨厌。所以,该是解决这些问题的时候了。

幸运的是,现在改正错误还不晚。人们意识到环境的重要性。我们已经开始尽力改善环境。法律也开始涉及到空气、水和噪音等问题。将来,河流会更清澈,天空会更晴朗,花朵会更鲜艳,阳光会更灿烂、更温暖。保护环境会使我们生活在一个更加美好的世界中。

Environmental Pollution

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more

popular. Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial

production and increased consumption of goods. Bedsides, the use of chemical substances

in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us. How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

一旦没有人想对他的环境的保护。有几个人在地球上,自然资源,这似乎是无限的。 如今,一切都不同。世界已经变得过于拥挤。我们正在利用我们的自然资源,并提出我们的水坑与危险化学品的环境。如果我们继续这样下去,地球上的生命将无法生存。 我们意识到,如果有太多的鱼从海中,不久将会都不剩了。但是,现代化的捕鱼方法,越来越多的鱼类提供caught.We知道太多的树木被砍伐,森林就会消失。但是,我们仍旧使用强大的机械砍伐越来越多的树木。我们都知道如果河水被废弃物污染的话,我们只有死路一条。然而,废物产品

配置放入河流。

我们知道,如果对目前的速度崛起在人口继续,在几年内,将不会有足够的food.What我们该如何解决这些问题呢?

如果我们多吃蔬菜,少吃肉类,将会有更多的食物。饲料作物用地的5倍多的人建议,土地上的动物将被保留。

我们的天然资源,才能够长久,如果我们学会recycie主题。

世界人口就不会增长如此之快,如果人们使用现代化的生育控制方法。

最后,如果我们能够教育人们去思考的问题,我们有毒品和香农在未来更洁净的星球

城市的环境-The Surroundings in Cities

We have to admit that, comparatively speaking, our cities are not so clean and green as those in the developed countries.

There are not adequate trees, lawns and flower-beds in such big cities as Beijing, Tianjin and Shanghai. We should make our cities greener by planting more trees, grass and flowers. A green environment can bring us pleasure, beauty and fresh air. Trees, lawns and flowers will make our cities more pleasing to both the eye and the mind, improve the weather conditions and provide fresh air, all of which will no doubt do us a lot of good.

I suggest that the whole city go all out every spring to plant new trees, build new lawns in and around the city, and everyone should take care of and protect the trees, lawns and flowers, and educate the children to love them. Then year after year, our cities will become greener, more beautiful and livable.

水源污染-Water pollution

Water is used in homes, in farming, and in manufacturing. The water used by the people comes from oceans, lakes, rivers, and streams. Many water sources are becoming polluted.

People are throwing things into the water. Factories are dumping waste materials into the water. Cities are dumping sewage into the water. Some water sources have become so badly polluted that the water cannot be made fit to use.

Would you like to drink water that came from a source that had been so badly mistreated? Now is the time that we should take up our responsibility to protect our environment from being polluted.

保持水源清洁-Keeping Water Sources Clean

Who is willing to drink the polluted water? It can cause us to be ill and even to die. We can't wait for a moment to protect our water sources. The water we use comes from oceans, lakes, rivers or streams. But many of these water sources are getting seriously polluted. Towns and cities are pouring dust into the water. Many people are throwing all kinds of dirty things into the water. Factories are pouring waste material into the water. Therefore, water sources have become so badly polluted that some of the water is unfit to drink or to use. Now it is high time that we should do something to protect our water environment from being polluted.

保持水源清洁污染的水会使人生病甚至死亡,有谁愿意喝这样的水呢?我们要保护水源,刻不容缓。我们用的水来自海洋、湖泊、河流或小溪,但这些水源有许多正受到严重的污染。城镇把大量的尘埃排入水中,许多人正把各种;各样的脏物投进水中,工厂正把废物排入水中。因此,水源已经污染严重,其中一些不适合再饮用。现在到了.采取措施保护水环境使其免受污染的时候了。

Reduce Waste on Campus(减少校园污染)

As is known to all, waste on campus has become a more and more serious problem. We can easily see many students dump a lot of food in the garbage can. Some students spend thousands of yuan buying fashionable clothes and so on.

The negative effects of waste can be shown in the following aspects. In the first place, it makes some students dependent on their parents for money, which is harmful to their development.

If they don’t learn to support themselves, they will be “useless people” when they graduate. In the second place, it is not easy for our parents to arrange for our schooling. Last but not the least important, there is no denying the fact that our country is still poor. There are many people who cannot go to university and many poor people still need our help.

As far as I am concerned, I should set a good example to reduce waste on campus. First of all, I will refrain from wasting anything, from food to stationery. What’s more, I’m determined to call on more schoolmates to fight against waste. Only through these measures can we hope to reduce waste on campus.

Water Is the Source of Life(水是生命之源)

As the source of life, water is indispensable to human beings. People consume much water in production and daily life. Agriculture and industry account for most of mankind's water usage. Without adequate water supplies, human future is threatened.

Nowadays water shortages touch a large percentage of world population. According to one UN study in 1999, nearly one in five people lack safe and clean water. Water elated diseases in some areas are killing people. Population explosion and water pollution make water crisis increasingly urgent. Water related problems are likely to worsen in the foreseeable future.

The situation is really alarming. Therefore, immediate and effective measures must be taken to protect and exploit water resources. Remember; where there is water, there is life. If we could not make proper use of water resources on earth, the last drop of water would be our teardrop.

The Water Cycle(水的循环)

Water can change from one form to another. The heat of the sun evaporates water from the oceans, seas, rivers and lakes. The heat also evaporates water from the ground and from plants and animals. Water vapour is formed. This forms clouds in the air.

When the clouds come near a mountain, they are forced to rise. As the clouds rise, they are cooled. The higher they rise, the more they are cooled. This causes more and more water vapour to condense. In this way, the tiny drops of water in the clouds get bigger and bigger until they are heavy enough to fall to the earth as rain.

Some rain water which falls on the earth is again evaporated. Some of it sinks into the ground. It may be used up by thirsty plants. It may reach a well or a spring. Most of the water goes back to the rivers, seas and oceans. This process then starts all over again. This process is called the water cycle.

Reuse the Wastes(废物利用)

我们在日常生活中产生少许多废物,比如像用过的纸张飞旧报纸、用过的塑料袋、罐头筒、瓶子等等~所以充分利用废品是十分重要的~

In everyday life, we have a lot of things, such as used paper, old newspapers, used plastic bags, cans, bottles and so on. It is important to make good use of the waist things.

There are some ways to reuse the wastes. The used plastic bags can be used to contain our family rubbish. The empty tins can be made into ashtrays. We can also make the used bottles into different kinds of handiwork. That will make our rooms more beautiful.

If we don't know how to reuse the wastes, we can sell them to the recycling station.

There are many other ways to reuse the wastes. If we try our best to recycle the wastes, there will be less waste and less pollution in our life.

To cherish the environment is tolove ourselves.

Pollution(污染)

As the world is getting more densely populated, pollution presents a severe problem. More people make more waste. All this waste is polluting our surroundings.

Pollution has a bad influence on our life. The air is polluted by the smoke and fog coming out of the factory chimneys. Plants die for want of fresh air. The river is polluted and the fish are unfit to live. There is noise pollution made by cars and factories, etc, which hurts the ear.

It is high time we did something about pollution. I suggest more trees be planted to keep the air fresh. We should purify the water and make use of the wastes and turn harm into good.

By cur common efforts, we will make a clean and purified environment for life and work.

污染

随着世界人口密度的增长,污染成了严重问题。人多产生的废物就多。所有的垃圾都在污染环境。

污染严重地影响我们的生活。工厂的烟囱里冒出的烟雾污染空气。植物由于缺少新鲜空气而枯死。河流污染,鱼不能生存。汽车、工厂发出噪音对人耳有害。

是对污染采取措施的时候了。我建议多植树以保持空气新鲜。我们应该使水净化,利用废物,转害为利。

通过共同努力,我们将创造一个清洁、美丽的生活、工作环境。
