关于核污染的演讲稿篇1

有许多事情，大家是不能忘记的。其中有一件事情我一提起，每一个内江人都还记忆犹新，那就是去年的沱江河水污染。

阳春三月，发生了一起河水污染事件，让美丽的沱江河成为了一条哭泣之河。从2月16日到3月2日川化二厂向沱江河排放纯氨氮20xx吨，河水发出恶臭，氨氮指标超标40-50倍，上游河段达到100倍，这可是惊人的数字呵，会致人怪病甚至患上癌症的，已造成了大规模死鱼，死鱼达50万公斤，沱江生态受到严重破坏，直接经济损失上亿元，致使简阳、资阳、内江百万居民停饮自来水。这是全国近年来最大的水污染事件。因为时间持续到3月2日，被称为“302”事故。现在时间虽然已过去一年多，排污工厂受到了处罚，工厂排污得到遏制，但河边污染水源的情况并未停止。河滩上到处都有烟头、纸屑、果皮、塑料袋等各种垃圾在污染河水。

针对现在的河水污染情况，我想，如果我是市长，我将会采取以下几种办法治理污染。

一、河滩放置垃圾桶。我发现现在河边没有垃圾桶，只有河堤上才有，而人们都有一种懒惰心理，丢一次垃圾要花几分钟，很麻烦，大多数人就干脆把它丢在河里和地上。就近在河滩放置几个垃圾桶，又花不了多少钱，简便易行，解决了人们丢垃圾麻烦的问题。

二、河滩设置管理人员。现在人们不想把垃圾丢进垃圾桶还有一个原因，就是人们发觉河滩没有人员管，可以乱丢垃圾，造成环境污染。安置管理人员强制管理人们的不卫生习惯。

三、加强环境保护的宣传教育。现在人们乱丢垃圾的另一个原因是环保意识差。要在办公室、学校等公共场所进行宣传，提高人们的环保观念。学校也可经常组织学生到河滩捡拾垃圾，增强学生的环保自觉意识。

四、多植树木，防止水土流失。大家知道黄河是怎么来的吗?就是因为它流过的地方有黄沙流失，积少成多，慢慢就成了黄河。如果我们多植树木，就可以防止河岸上泥土流失，以免成为第二条黄河。

能按这样做，我相信一年内沱江河将成为最干净的河。

现在我们应该保护水资源，防止沱江河发生第二次河水污染。

有了水，才构成这个蔚蓝的星球;有了水，整个世界才有了生命的气息;有了水，我们的世界才变得生机盎然;有了水，我们才有了秀美的山川、清澈的溪水、湛蓝的海洋……我们才有了一切。

关于核污染的演讲稿篇2

尊敬的老师，亲爱的同学：

大家下午好：

我的家乡在荆州。平时，我对家乡的环境也不大了解。这几天，我们班组织同学们进行了一次综合实践活动，对家乡的环境进行了一次调查，调查的主要对象是荆州的护城河。这次调查让我受益匪浅。

经过实地调查和上网查资料，我了解到以前的荆州护城河污染十分严重。护城河两侧共有二十多个排污口，每一天城区的生活及工业污水排入护城河，直接排入的总污水量约5万立方米。

所以，河水变成了浑浊的墨绿色。居住在附近的居民和过往的行人也很不爱护环境，把垃圾随随便便仍进河里，使河水的污染进一步加重。由于护城河是死水，无法流动，河底淤泥十分多，水面上漂浮着很多的蓝藻，河底的沉积物散发着臭味。人们从那里经过，都要捂着鼻子，加快脚步。

护城河的污染成为了荆州人的心中之痛。在广大市民的期盼下，市政府对护城河进行了彻底的治理。经过清淤、补水、截污、绿化……护城河面貌焕然一新。

如今的护城河碧波荡漾，波光粼粼。护城河宛如一面绿色的大镜子，映出了蓝天白云和古老城墙的美丽倒影。几只鸭子在水面上嬉戏，几条小船在小河上悠闲地驶来驶去，真可谓“舟行碧波上，人在画中游”。河岸上杨枊依依，与古老的城墙交相辉映，美不胜收。

经过这次的环境调查，我增强了环保意识。我们必须要好好保护环境，让我们共同的家园天更蓝、水更清、景色更美! 关于环境污染的演讲稿 第11篇

敬爱的老师、同学们：

大家早上好！我是xxx。今天我讲的题目是：低碳生活，共抗雾霾。

同学们一定对不久前南京成了“雾都”记忆犹新。雾霾天气逐渐加重，影响到了我们正常的'生活，危害了我们的身体健康。那什么是雾霾呢？雾霾，雾和霾的统称。雾霾的主要组成部分是可吸入颗粒物，也就是我们众所周知的pm2.5。这些颗粒散播在大气中，影响了空气质量，加剧疾病传染，威胁着人们的身体健康。雾霾天气属于严重空气污染事件，污染物排放量大是根本原因。因此，爱护保护我们的生活环境，应是每个公民应自觉遵守的。 在这样的雾霾天气里，戴什么口罩成了大家的热点。在大街上，许多人都是戴卡通口罩或医生专用蓝色口罩，但这些口罩对于pm2.5颗粒基本起不到什么作用，建议大家最好戴n95口罩或“猪嘴”型的口罩，这样的口罩戴起来会紧紧贴着皮肤，雾霾不会进去，就算在pm2.5爆表的时候也会起到很大的作用。另外，我要提醒大家哦，戴完口罩后，应及时清洗，以免滋生细菌，而且佩戴时间不宜过长，这样可能会导致呼吸困难或头昏等症状。

在这样的雾霾天气里，我们又应该吃什么呢？其实，在这样的季节里最好能吃清淡食品，多吃蔬菜水果，尤其是胡萝卜，因为胡萝卜有着让大肠通常以及杀菌的作用，能有效抵抗雾霾。那我们又该喝什么呢？推荐大家一早起来能够喝一杯热的白开水、蜂蜜水或柠檬水，这样有助于清洗肠道、清润喉咙的作用。

另外，我们还应该做好个人卫生。我们进入室内后要及时洗脸、漱口、清理鼻腔，去掉身上残留的颗粒。洗脸时，我们应用热水洗；漱口时，也最好用热水；清理鼻腔时，最好利用热水用鼻子轻轻吸水并迅苏擤鼻涕，同时也要避免呛咳。

同学们，让我们从现在做起，从自身做起，用实际行动，来诠释低碳的生活方式，与危害我们健康的雾霾做斗争！

谢谢大家，我的演讲结束了。

关于核污染的演讲稿篇3

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.

关于核污染的演讲稿篇4

“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！

关于核污染的演讲稿篇5

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!

关于核污染的演讲稿篇6

从工业革命开始，人类进入了一个新的时期，科技飞速发展，我们的生活越来越便利与快捷。然而，地球的环境却成了“牺牲品”。试想，数十年之后，原本美丽的地球将会变成什么样？天空中布满乌云，时不时降下酸雨；臭氧层被破坏，太阳的紫外线能灼伤肌肤；昔日的森林变成了不毛之地，植物濒临灭绝……当然，这只是我们没有保护好环境的可悲下场。如果大家都不愿看到这种悲情的发生，我们就要从现在开始保护好地球的环境，珍惜我们的生存家园。

说到保护环境，许多人可能会想：这些大事情和我们小孩子没什么关系，科学家啊、政府啊才负责做这些事情，让他们去解决吧！如果你这么想，那可就大错特错了。保护环境，人人有责，当然需要我们在不同层面上对环保负责。只有每个人都参与进来，环境的问题才能被真正解决。

作为学生的我们到底该怎么做呢？表面上看很困难，其实，不经意间你也许就为保护环境出了一份力：少用塑料袋，少开空调，不随地丢垃圾，不破坏植物，多坐公共汽车，多种花草……这些都是保护环境的点滴行为。

炎炎夏日的时候，我觉得家里闷，开着空调又太浪费。于是，我想和爸爸一起去游泳。爸爸对我说：“我们开车去吧。”我摇摇头，说：“开车耗能源，游泳池离这儿不远，不如步行吧。”爸爸称赞说：“好主意，你真是个懂得节约的好孩子。”于是，我们就骑着自行车前往。这样，既锻炼了身体，又节约了能源，真是一举两得！

我奶奶是最环保的人，她总是用淘米水来浇花浇草。其实淘米水对花草而言比清水更有营养，不但节约了水，而且还能让花草更好地生长。另外，我家在用洗衣机洗衣服时，总是将较干净的洗衣水用一个大盆收集起来，用来拖地板，冲刷马桶。这样循环利用，节约用水。

……

保护环境是一种生活态度，许多人有了这个意识，但很少付诸行动；有些人也确实行动了，可没有一直坚持。做到这些简单的环保事情需要具备三个条件：环保意识、环保行为和环保毅力。只有这样，保护环境才能真正的“从我做起”。

地球的环境在人类快速发展的影响下已经每况愈下，“救救地球”已成为世界各国人民烈的呼声。让我们从节电、节水、节碳、节油、节气这些小事做起，一起去构建低碳绿色的生活方式吧！

关于核污染的演讲稿篇7

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.
