现代的人们大多数做饭用煤气、煤炉，舍弃了用稻柴烧火的时代，可他们不知道这样的行为大大污染了空气，污染了环境。尽管秀多人家烧菜时用吸油烟机，净化了家中的空气，但油烟机不可能完全吸入烟气，一部分烟气依然会流到空气中，一家人每天产生的烟气或许对大气污染没有什么影响，但是几十家、几万家、几亿家呢？几亿家产生的烟气汇集在一块难道仅有一点吗？难道就不会对空气产生污染吗？这个问题值得深思，我们必须静下心来好好反思，好好考虑。

一些地区沼气池进入人们的日常生活，沼气可以照明、取暖、做饭，这样不仅可以节约资源，而且还能减少对环境的污染、破坏，有利于大自然的和谐发展，有利于节约型社会的建设。

不光是大气污染，电池污染也成为当今的主要环境问题之一。许多人毫无环保意识，乱扔电池，随意把电池扔在垃圾桶里和其他垃圾混合在一起，不将垃圾分类，导致清洁工可能会随便处理这种有害垃圾。他们可曾知道，一只电池会污染一吨水，大大减小了水资源的现存量，我国不得不大力实行相关措施，净化水资源，可要挽救水需要多大的人力、物力、财力，这要花费多少我国的资金？所以，我们应该把垃圾分类，回收有用的垃圾，减少塑料袋、一次性快餐盒的使用，实行可持续发展战略，实行经济循环模式，合理利用资源，减少不可回收垃圾，减少对环境的污染，让地球成为一个更舒适的、更美丽的家园。

一些工厂现在采用煤碳烧制东西，煤碳中含有二氧化硫，会形成酸雨，酸雨对环境有很大的污染，严重地破坏了大自然。人类无情地对待大自然，大自然也会给人类以报复，会造成许多的自然灾害。自然灾害会给人的生活带来很大影响，生活在这样一个受污染的环境中，不利于人的身心健康，也话在将来的某一天，地球会因我们犯下的罪行而毁灭。

不容置疑，为了保护我们的地球不被破灭，为了使我们的生活不受影响，我们必须增强环保意识，积极参加宣传环保活动。为了共同建设资源节约型社会，对现在存在的一些生活习惯应予根除，开发沼气和热水器等的使用，应迅速放到议事日程上来并且应迅速实施。

关于污染的演讲稿篇2

“青山？绿水？人类只能在泪水中回忆！”

“鸟语？花香？人类只能在懊悔中挣扎！”

拖着疲惫的躯壳，暴风刮得着实吓人，汽车不再奔驰，人影不在路边出现，成堆的垃圾代替了整齐的房子，干涸的河床显现出来，干瘪的鱼骨在河床上“站立”，这真的是我们以后想要的吗？

现在的环境也没有多好，总有垃圾果皮在河中“漂荡”，总有塑料袋在空中“飞翔”，总有纸巾在树上“吊着”，这些垃圾简直是无处不在！河水从原本来的干净变成了肮脏，从原来的碧蓝变成了墨黑，从原来的无味变得恶臭，可笑的是，我们还作为观众在对发生的一切视若无睹。人们啊，你们到底想怎么样？！想继续导演这场悲剧？还是从那个这场噩梦中苏醒？

地球是我们的母亲，她已经哺育了一代代人类，可我们却把生我们的母亲弄得多么狼狈，你们于心何忍啊！

保护环境，从我做起；低碳生活，方法多多：

1、我们不能再和塑料袋“做朋友”了，要多使用布袋，如果实在想和塑料袋“做朋友”，那就只能一心一意。

2、生活中我们肯定用了不少纸盒、瓶子，那么多材料我们可以直接回收，或者废物利用。我们可以把瓶子洗净，用来继续喝水；我们可以在瓶子盖头上戳几个小洞，把已用过的水灌进去，变成一个浇花器；我们可以把废盒子的顶部剪去，再在竖着的另外四面进行装饰、修剪花纹，可以做成一个收纳盒……自己动手，发挥想象吧！

3、我们每人家里都要用水，洗脸用水、洗菜用水……我们每天都要用水，那么全球淡水资源肯定会日益紧张，所以我们要节约用水。淘米水很有营养，我们可以把脏东西过滤出来后用来洗脸，洗完后可以冲马桶；我们可以用淘米水洗菜，洗菜水浇花……如果每人省一盆水，中国就能省13多亿盆水，整个世界一天就能省70多亿盆水，多么庞大的数字啊！

4、我们可以在生活中骑自行车出行。如果目的地不是很远，建议买辆自行车，既有利于身体健康，又环保，还不用因为赛车而迟到了。如果要出远门，建议您坐公交车，只需一元，既省钱，又环保。

我曾经在一篇同学的作文里知道一个小女孩的故事。这个小女孩每天放学回家，做完作业就去外面散步，如果看见一些瓶瓶罐罐、纸屑、果皮就主动捡起扔进垃圾箱。当然，她在家也把废物变成了一件件生活中的小物品。比如纸杯做的花瓶、牛奶盒做得笔筒等，难道我们不应该向她学习吗？

生活点点滴滴，环保从我做起，支持低碳生活，拒绝污染环境！让我们把这句话铭记于心吧！

关于污染的演讲稿篇3

pollution in the ocean is a major problem that is affecting the ocean and the rest of the earth, too. pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. oil spills, toxic wastes, and dumping of other harmful materials are all major sources of pollution in the ocean. people should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.

what are toxic wastes?

toxic wastes are poisonous materials that are being dumped into the ocean. they harm many plants and animals in the ocean and have a huge impact on our health. toxic waste is the most harmful form of pollution to sea life and humans. when toxic waste harms an organism, it can quickly be passed along the food chain and may eventually end up being our seafood. in the food chain, one toxic organism gets eaten by another, larger animal, which gets eaten by another animal, and can end up being our seafood. toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.

many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population. one of the most harmful chemicals in the ocean is lead. lead can cause many health problems. it can damage the brain, kidneys, and reproductive system. lead can also cause birth defects for people. it has been shown to cause low iq scores, slow growth, and hearing problems for small children. house and car paint and manufacturing lead batteries, fishing lures, certain parts of bullets, some ceramic ware, water pipes, and fixtures all give off lead.

many things found in the ocean may cause seafood to be dangerous to human health. the effect on humans from contaminated seafood may include birth defects and nervous system damage. medical waste found in the ocean is being tested to see if swimmers have a chance of developing hepatitis or aids. other waste has been known to cause viral and bacterial diseases. this type of pollution can be stopped by watching what pollution we are letting into the ocean. people are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean.

boating pollution prevention tips

whenever someone takes their boat onto the water for a ride, it is creating pollution that can be very harmful to the sea life. boating pollution is the pollution that comes from the boatsquo;s engine when it is running, and it pollutes the water, killing animals with the chemicals in the exhaust from the engine. the engine gives off excess gasoline, which pollutes the waters and ends up killing the animals. in order to make as little pollution as possible, what everyone can do to help is:

only turn a boat engine on all the way when you need to.

donsquo;t take your boat out into the water if you donsquo;t need to.

be sure to store and transport gasoline in places where there isnsquo;t any direct sunlight because the gasoline will evaporate, and all of the gases that have been evaporated will pollute the air.

every year, buy new or cleaner marine engines for your boats.

garbage dumping

garbage dumping is the dumping of harmful materials into the ocean like human waste, ground-up garbage, water from bathing, and plastics. most of the waste that has been dumped into the ocean in the early 1990squo;s is still there today. one main cause of garbage dumping occurs when sewage pipes share their space with storm water drains. rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain, which flows into another water source such as a lake or river. after that, the garbage pollutes the ocean, kills plants and animals in the water (for example, the plastic rings that are around pop cans can get around an animalsquo;s neck, causing it to suffocate), and makes the water dirty.

关于污染的演讲稿篇4

随哥本哈根气候大会的召开，“绿色”、“环保”这等词早已脍炙人口，深入人心，成为了全球关注的焦点。世界环保日，世界关灯一小时，新能源的开发和利用，似乎能源危机和环境污染已成为了世界人民心上的一支利剑，不知何时何地就会射发，危及人类的命运。但事实的确如此，这个孕育了我们祖先，创造无数奇葩的自然生态圈，缺了一处两处，便会像多米诺骨牌一样，一触便不可收拾。

于是有了绿色环保的活动，有的人参与是为了缓解自己对于“20xx”的恐惧感，有的人因此而成为“环保达人”，追名逐利，当然，也有人并且是大部分积极地保护自然，拥有了一颗绿色健康的心灵。且不论这等人的孰是孰非，作为一名高中生，在全球的环保热中，我们又该扮演何种角色？又该从哪方面入手？

人们常说，从小事入手，从点滴开始，于是让我们看看一张纸巾的蝴蝶效应……

洗完手，一张纸巾在手，用过便丢了；抑或擦了一滴墨水，就把一张三层的至今蹂躏完后扔向纸篓；更有甚者闲来无趣便撕个纸条玩，这种情状发生在我们随性潇洒的90后身上仿佛是与生俱来般的自然。但一张纸的价值不仅在此，若每个人都能节省一张纸，结果可是完全不同的。

一棵10年树龄的树可以制成20xx张纸巾。那么以中国为例，13亿人口每个人节省一张纸巾，那么，将会有约650000棵树免遭砍伐。而每一棵树每天吸收的二氧化碳量大约为5023克，一年就有将近1。83吨，每天放出的氧气有约3653克，一年就有将近1。3吨的氧气被放出，每吨的价值在31250美元左右。650000棵树，一年就有1190000吨的二氧化碳被吸收，价值26400000000美元的845000吨氧气被生产出来。

没错，千万别怀疑，这就是节省一张纸的事情。

因此，无论事大事小，环保自在人心。

就如我们学校此次的国庆通宵，在班级布置方面，学校力求节俭创新，于是，在资金限制和时间有限的双重压力下，我们拿出了上次通宵活动用来布置教室的物品，裁裁剪剪拼拼，俨然又成了另一新物。创新有了，节俭也有了，可谓双赢。就这样，当被同学问及班级布置材料来源时，我会心一笑“都是去年的”。“全部都是？”“恩，全部都是”同学惊讶的表情业已说明了一次环保活动在无形中生成了。

敬爱的老师，亲爱的同学：

最近几天，我着重观察了周围的环境，发现有很多方面都十分得不好，经过仔细分析，主要有以下几点不足：

1、街道、居民区、闹市区和马路上的垃圾很多，包装纸、塑料袋随处可见。风一刮起来，这些垃圾就随着沙土一齐飞扬，“袭击”着路人。

2、空气不清新，污染严重，使得病菌们更嚣张跋扈的在春季横行，很多人都染上了感冒和一些呼吸道疾病。

3、大街上会有一些小贩弄得地面很不干净，每当他们收摊回家，总能看见地上散落着响市容市貌，还会不时地发出(zw.作文：关于环保的作文)刺鼻的臭味，有时还会妨碍交通。

之后，我左思右想，家乡的'环境变成这样，不就因为我们自我吗路上会有那么多垃圾，还不都是市民们为了一时的方便，吃完东西后随手就扔，对路边的垃圾桶视若无睹，并没有很强烈的环保意识，才会乱倒乱扔垃圾的。

虽然政府已经严禁一些工业排废水、废渣、废气了，可是还有些民办企业总是污染环境。难道他们在谋取暴利的时候，没有看到那烟囱里冒出的黑烟吗家乡的拒马河不就是一个鲜活的例子吗以往是“拒马长虹，双塔青烟”的家乡，如今已被破坏的体无完肤。随着科学技术的提高和社会的发展，机动车越来越多，空气污染指数越来越高，我们该怎样生活啊!

所以，让我们从小事做起，来保护环境，保护我们共同的家园吧!

teachers students:

hello everybody

today i lecture on the topic of air pollution. air pollution is a new branch of atmospheric science it is to study in different weather conditions into the atmosphere of the pollutants in the atmosphere transmission dilute diffusion transformation and remove the rule and application of science. this subject originated from the 20xx s 20 years british atmospheric diffusion experiment was carried out but only in the '50 s the development of modern industry and city population is highly concentrated there appeared the serious urban or industrial pollution events in december 20 's london smog event for example took the lives of more than four thousand people these make people wide attention and research of atmospheric pollution to the 60 s then gradually formed this new independent discipline.

air pollution due to human activity or natural process and out into the atmosphere into some harmful substances (pollutants) when the amount of discharged into enough (pollutant concentration up to a limit) makes the original clean air quality to drop if this situation is maintained long enough will be to humans animals plants and the atmosphere cause harm and adverse effects of the atmospheric state known as air pollution. of air pollution has three elements: the concentration of pollution sources and pollutants harm to human and biological.

clean the atmosphere is one of the necessary conditions for the survival of humans in one person in five weeks no eating or five days without drinking water to be able to sustain life but not breathing air for more than 5 minutes then die the body to absorb every day 10-12 cubic meter of air. thus eliminating air pollution or keep pollution concentration falls below a certain limit is how important.

pollution sources and pollutants discharged into the source of harmful substances into the atmosphere pollution sources harmful substances into the atmosphere pollutants. atmospheric pollution source points of artificial and natural sources

the harm of air pollution and influence

atmospheric pollution on human and environment caused by the harm and influence has gradually been recognized in the aggregate has the following several aspects:

(1) the harm to human health. human suffering has three pollute the air surface skin contact with the air inhaled and eating food containing atmospheric pollutants besides can cause respiratory and lung diseases but also on the cardiovascular system liver etc serious can take away the life.

(2) the harm of biological. animals because of the inhaled air pollution or eat foods containing contaminants and disease or death atmospheric pollutants can make the plant disease resistance drop influence the growth leaf spot wither or die.

(3) the harm of items. such as the textile clothing leather metal products construction materials culture art etc. chemical damage and defiled damage.

(4) cause acidic precipitation such as agriculture forestry fresh water aquaculture.

(5) destroys the high-altitude ozone layer ozone hole formation cause harm to human and biological survival environment.

6. impact on the global climate such as the increase in carbon dioxide and other greenhouse gases will cause the earth's atmosphere warms lead to increased global weather disasters and aerosol particles such as smoke increase the atmospheric turbidity solar radiation affect the longwave radiation the earth may lead to abnormal weather climate.

how to prevention and control of atmospheric pollution reduce the harm of air pollution and influence constitute a major and urgent research subject. prevention and control of atmospheric pollution

prevention and control of atmospheric pollution is a huge system engineering need to be individual and collective national and the joint efforts of the world can consider to take measures in the following aspects:

(1) to reduce emissions. use more pollution-free energy (such as solar energy wind energy hydroelectric power) reform the energy structure with low pollution energy (such as natural gas) pretreatment of fuel (such as coal desulfurization) before such as improving combustion technology can reduce emissions. in addition before the pollutants into the atmosphere not use dust smoke abatement technology condensing technology liquid absorption technology recycling technology to eliminate some pollutants in the exhaust and can reduce the amount of pollutants into the atmosphere.

(2) to curb emissions and make full use of atmospheric self-purification ability. different meteorological conditions the capacity of the atmospheric pollutants into the same amount of pollutants the pollutant concentration was different. for wind good ventilation turbulence strong convection area and time atmospheric diffusion dilution ability is strong can accept more corporations to inversion region and time atmospheric diffusion dilution ability is weak cannot accept more pollutants otherwise it will cause serious air pollution. therefore respond to different regions different times for the effective control of emissions.

(3) site selection design of chimney urban and industrial planning should be reasonable don't emitters transition concentration repeated superposition don't cause pollution formation of local serious pollution incident.

(4) greening afforestation make more plants absorb pollutants reduce atmospheric pollution.

through the above explanation we know the importance of air for our human right from now on please protect the environment afforestation and create a better living environment!

today my speech is that under the flag of thank you.

关于污染的演讲稿篇7

地下水水质急转直下，表明单纯依靠水体“自我修复”已不可能，地下水的环境承载能力已经超越了临界点。不要说我们的子孙后代怎样怎样，地下水污染形势之严峻、迫切，已经到了我们这一代人也无法独善其身的境地。

水利部最近公开的20xx年1月《地下水动态月报》显示，全国地下水普遍“水质较差”。具体来看，水利部于20xx年对分布于松辽平原、黄淮海平原、山西及西北地区盆地和平原、江汉平原的2103眼地下水水井进行了监测，监测结果显示：iv类水691个，占32.9%;v类水994个，占 47.3%，两者合计占比为80.2%。

尽管公众对地下水污染不乏直观了解，但超八成地下水遭受污染威胁的监测结果，还是让人惊悚。这意味着，不止地表水已被大面积严重污染，就连那些视线难以企及的浅层地下水，也难逃污染魔咒。这也意味着，鉴于水体修复的艰难，地下水污染的治理远比地表水体更复杂，尤其是重金属污染、持久性有机物污染很难被传统水处理工艺消灭。

一味回避问题，或者干脆交由时间来发挥“自净”功能，显然已不太现实。地下水水质急转直下，表明单纯依靠水体“自我修复”已不可能，地下水的环境承载能力已经超越了临界点，再也没有平衡点，也等不下去了。不要说我们的子孙后代怎样怎样，地下水污染形势之严峻、迫切，已经到了我们这一代人也无法独善其身的境地。

当务之急，一方面，必须以最严厉的措施斩断污染企业的随意超标排放，特别是在重金属污染、持久性有机物污染方面，更要毫不犹豫采取措施，并确保落实，先改变污染不断加剧的趋势。此前媒体曝光的某地多家企业“将污水排到1000多米水层污染地下水”等情形，必须彻底铲除，任何来自权力与资本的阻挠，都不应该动摇治理决心。

与治理雾霾一样，对那些心存侥幸、欺上瞒下的市场主体，理应采取最严厉的罚则，甚至可以研究制定退出机制，使土壤和水免于遭受更严重的污染。政府监管部门也应该负起责任来，既不能敷衍塞责，采用应付、糊弄的做法，默认甚至纵容污染企业肆意破坏我们的生命之源，而对于那些奉gdp为圭臬的地方政府，不妨课以行政和司法问责。

另一方面，还应该从长计议，以顶层设计制定最严格的地下水管理措施。去年4月，国务院印发《水污染防治行动计划》，明确提出，全面控制污染物排放，切实加强水环境管理，到20xx年，全国七大重点流域水质优良比例总体达到75%以上，城市建成区黑臭水体总体得到消除，城市集中式饮用水水源水质达到或优于Ⅲ类比例总体为95%左右。

也要注意到，这个被称为史上最严的“水十条”，更多关注的是地表水的概念，地下水尚未进入治理视野。当然，浅层地下水的污染，与地表水的污染存在 “相互影响”的关系。举凡浅层地下水被污染的区域，其地表水也一定被严重污染。这样的互动关系恰恰说明，在水污染的治理上应该标本皆治，协同治理，同步进行，而不能只是单向突进。

尽管目前的《水污染防治法》对地下水污染有专章规定，但是，地下水排污在中国没有严格、明确的规范，基本上处于一种放任自流的状态。应该尽快提高对地下水污染的认知程度，并出台同样严厉的治理措施。我国地下水污染已经到了不得不正视、不得不从根本上遏制的时候了，再不治理，不仅农村地区，城市也将难有清洁的水源。

说到底，地下水污染治理，信息披露不是问题，也并不存在技术上的门槛，关键在于行动，而不能只是喊“狼来了”;关键在于我们是不是真的有决心转换发展方式，是不是愿意从以往粗放式、以牺牲环境和民众健康为代价寻求发展的思路走出来。水，既是我们生活的必需品，也是一个社会的公共品，其公共特征决定了，政府在这一问题上责无旁贷。
