写污染的作文 篇1
我们环保小队选择去柳市镇马来浃内河调查家乡的水污染情况。
镇政府治水办公室的王老师带我们一行人沿着河岸边走边就近观察内河，我们看到内河被分成了两段，其中一段河面上种植着一大片绿油油的水植物，王老师向我们介绍：这是一种净化河水的植物狐尾草，水受到污染后，它可以净化河水，使它变的清澈；另一段内河用障碍物隔离成了小池塘模样，只见河面上漂着好多个蓝色作业工具增氧机，增氧机每隔一段时间就不断翻滚起来，通过这样的增氧作业使河水活起来，有利于鱼、水植等的存活。王老师从内河提了一桶水让我们观察，我们拿它跟矿泉水比，通过比较观察，我们发现矿泉水清澈无比，很想喝它解渴；而河水很浑浊，其中还有少量水虫、还有一丝异味，想远离并赶紧倒掉。这还是二期治水的效果，水污染情况还是非常严重的。接着，我们一群人来到会议室讨论，同时王老师问我们：政府可以采取哪些措施来治理水污染。我们几乎异口同声的说道：种狐尾草，清理河道。王老师听完我们的回答后，微笑着点头，同时，向我们补充介绍政府还这样做：1。加快污水处理厂的建设进度；2、加快排污口整治；3、实现生活污水处理能力；制定科学生态调水方案；5、加强河边三化工作
通过这次活动，让我更加深刻意识到水污染带来的危害，治水工作的严峻艰辛，保护水环境也要从自身做起，不向河里扔垃圾树立正确的环境保护意识。
写污染的作文 篇2
近年来，大气污染非常严重，雾霾几乎每天都笼罩着天空，不仅给我们的交通安全带来隐患，而且威胁着人们的身心健康。如何改变这种恶劣的环境，净化城市空气已成为当下人们关注的热门话题。日前，《唐山市重度污染天气预警应急响应预案(暂行)》和《唐山市2013--2017年大气污染防止攻坚战行动实施方案》相聚出台，这项举措足以证实各级政府对环境治理的决心和信念。对此。人们不禁拍手称道。
众所周知，造成大气污染的来源诸多，主要来源有三类：其一是生产性污染，这是大气污染的，例如，燃料的燃烧，主要是煤和石油燃烧过程中排放的大量有害物质，如烧煤可排出烟尘和二氧化硫;烧石油可排出二氧化硫和一氧化碳等;另外，生产过程排出的烟尘和废气，以火力发电厂、钢铁厂、石油化工厂、水泥厂等对大气污染最为严重，还有就是农业生产过程中喷洒农药而产生的粉尘和雾滴。 其二是生活性污染，由生活炉灶和采暖锅炉耗用煤炭产生的烟尘、二氧化硫等有害气体。 其三是交通运输性污染，汽车、火车、轮船和飞机等排出的尾气，其中汽车排出有害尾气距呼吸带最近，而能被人直接吸入，其污染物主要是氮氧化物、碳氢化合物、一氧化碳和铅尘等。环境污染是个老生常谈的问题了，之所以越来越严重，一是污染企业的管理者利益驱使金钱作祟，二是政府部门的打击治理的力度不够。这次治理大气污染各级政府重拳出击，人们称赞之余更是拭目以待。治理生产性污染，政府及相关部门要严格治理，对于超标排放的企业坚决取缔，切不可像“治理大型货车超载交了罚款就放行”，而一罚了之，而且要长效监督，杜绝反弹。
写污染的作文 篇3
在小荷，大家都学到了很多，收获了很多．
当初选择小荷，是认为这是一片净土，一片能尽情抒发内心的净土．可现在突然发现原来这也早已变得很世俗一样．
这片净土已不在是净土了．它已经被污染，被摧残得遍体鳞伤了．
这些，在来小荷网不久后便渐渐清晰．
小荷这一片净土，看似净，却已金玉其外，败絮其中了．在小荷，把初级会员和高级会员分得很清．这便让嫉妒心大肆增加．很多人想，我为什么就不能当高级会员？于是，在这片净土上，世俗的观念愈来愈明显．
很多人拼命地写作文，投稿，就是想要满足自己的虚荣心．小荷，让我们失去太多．
我们失去了纯真的性情，取之而代的是妒忌与虚荣，我们失去了美好的友谊，取之而代的是攀比和骄傲．
小荷，你这片净土还净么？
小荷，你这朵出淤泥而不染的清荷还清么？
小荷，你这个与重不同的地方还新么？
小荷，希望你还能是那片净土，希望你还能是那多出淤泥而不然的清荷，希望你还是个与重不同的地方！

汽车污染英语作文三：Car Pollution
Each year there is an increasing number of cars on the roads as millions of new cars are produced. One out of six Americans works at making cars, driving trucks, building roads or filling up gas. Americans couldn't live without cars!
Most Americans would find it hard to imagine life without a car. However, some have realized the serious problem of air pollution caused by cars. The polluted air becomes poisonous and dangerous to health.
One way to get rid of the polluted air is to make a car without pollution. But to build a clean car is easier said than done. Progress in this field is slow.
Another way is to replace car engines with something else. Inventors are now working on steam cars as well as electric cars. Many makers believe that it will take years to develop a practical model for us.
To prevent the world from being polluted by cars, we have to make some changes in our lives. Americans, for example, have to cut down on the number of their total cars.They are encouraged to use bicycles, which are thought to help keep the air clean.
But this change does not come easily. A large number of workers may find themselves without jobs if a car factory cioses down. Thus the problem of air pollution would become less important than that of unemployment. Although cars have led us to a better life, they have also brought us new problems.

保护环境英文作文（五）：Protecting the Environment
There are still many problems of environmental protection in recent years. One of the most serious problems is 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. What is more, vegetation had been greatly reduced with the rapid growth of modern cities.
To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.
In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

写污染的作文 篇6
今天我们蓝金石假日小队去茅家埠调查有关水源污染的情况。我们分别以下天竺、中天竺、上天竺等五个地方取样、采访的方式开展调查。
首先，我们来到下天竺。那里的水不但很凉，而且清澈见底。我们在这里取了第一瓶样品。
沿着溪流顺着中天竺方向走，那有一座用石头砌成的石桥，一眼望下去，犹如万丈深渊。我们采访了几位居住在这附近的居民，她们说以前这里水的非常清。但现在下面的水面有许多垃圾。一个阿姨正在河边洗衣服，我们看到这样的情景立刻跑下石梯跟那位正在洗衣服的阿姨说：这样洗衣服会把溪水污染的。阿姨听了感到非常难为情就不跟我们讲话了。在这里我们取了第二瓶样品。
接着，我们来到了中天竺。这里的人和水都比较少，所以我们直接取了第三瓶样品；一会儿功夫我们来到了中天竺和上天竺之间。这里有“一湖七潭映月”的景观，湖面平静地像一面镜子，在阳光的照映下，镜子闪亮闪亮的，说明这里的水没有受污染，这就是我们取的第四瓶样品了。
最后我们来到上天竺。这边的水比较浑浊，可能是因为下了几天的雨，把山上的泥土冲下来了，所以上天竺的水变得这么浑浊，如果不是这么多天的的连续下雨这里的水应该是比较清澈的，第五瓶样品水也取好了。
取样采访结束了，我们对五个地点取的水样进行了比对。最终结果是中天竺的水质最好，上天竺到中天竺之间比较好，最差的是中天竺到下天竺之间。这就说明我们的水正在受污染。鱼儿离不开水，我们人类更离不开水，水是我们生命的源泉，我们呼吁全社会的人都像保护生命一样来保护水资源。
写污染的作文 篇7
有一天，我回家，刚要敲门，发现我们家外面的墙上和门上全都是一些乱七八糟的小广告，有开锁的，有搬家的，还有打扫卫生的，反正各种各样的小广告都有。
看到这些小广告，我就生气的把它们全都撕了。我走进家里，把这件事告诉了爷爷，爷爷马上把物业找过来，叫他们不要让外人进来贴小广告。说完，我们就回家了。第二天，我放学回家一看墙上和门上的小广告不但没减少反而增多了，我希望大家不要乱贴小广告，我们楼下二楼那家还拿粉笔在墙上写道∶不许贴小广告。自从她们家写了这句话后，小广告就越来越少了。
有一天，我刚走在小区的路上，发现一股难闻的味道向我袭来，我仔细一看，原来是小区的垃圾房好多天没有打扫了，而且清洁工都把垃圾堆在外面，气味难闻死了。
让我们一起保护环境，美化家园，手拉着手建立美好的生活环境吧！
写污染的作文 篇8
有一年，一家造纸工厂开工了，烟筒里冒出了黑烟，黑烟弥漫了蓝蓝的天空，挡住了火红火红的太阳，天空一片乌黑。
一天，黑烟造成的污染太大了，池塘里的鱼都漂上来了，河面上还有许多垃圾。小燕子正从北方飞了过来，看见小鱼朋友漂浮在水面上，在一看造纸厂烟囱上的黑烟，就知道小鱼是怎么死的了，小燕子说：我一定要为鱼朋友出口气，说服造纸厂的人，让他们保护环境。
小燕子挺身而出。在地上咬起一块石头，向造纸厂快速的飞去，咬紧石头，进了造纸厂，扔到了造纸的机器里，造纸的机器卡住了，工作人员来了，小燕子又扔了一块，扔到了工作人员的头上，工作人员大骂道：臭燕子，赶快滚开，小燕子生气的说：人们污染了环境，如果你们在污染的话，我救报警了，工作人员听了，就走了。
从此以后，造纸厂不再冒烟了，太阳又重新升了起来，照亮了大地。
写污染的作文 篇9
“绿水青山，都是金山银山”，是这次环保节的主题。的确是这样，如果不注意环保，呼吸的空气，喝的水，生长的土地，都会受到污染，我们就会生病，植物也会枯萎，所以，我们要好好的保护环境。
现在，污染最严重的就属大气污染，也就是我们俗称的空气污染，空气一旦被污染，我们就会呼吸不到新鲜的空气，那我们的生命就会受到威胁。空气为什么会受到污染呢？工厂的排气，汽车的尾气，焚烧的标杆……都是污染的来源。我现在还不能理解他们为什么会这样做，我只想着我们能有一片自由呼吸的空气，不让自己吸入有害气体。
另一个严重的污染就是水污染了。在我上幼儿园之前，我一直住在乡下，那时候小河里还有小鱼，夏天，大人也会带我们去河里洗个澡，捉一些小鱼，十分开心。前段时间再回老家，小河里的水变得浑浊不堪，里面乱七八糟的放着一些农药瓶，塑料袋等一些垃圾，小生物不见了，一起下河的小伙伴也没有了，让我心里难受不已。
是谁污染了我们生存的地球，难道为了经济的发展，就要以牺牲我们健康为代价来换吗？
写污染的作文 篇10
人一直以为地球上的海、陆、空是无穷尽的，所以从不担心把千万吨废气送到天空去，又把数以亿吨计的垃圾倒进海洋。大家都认为世界这么大，这一点废物算什么？我们错了，其实地球虽大，但生物只能在海拔8千米到海底11千米的范围内生活，而占了95%的生物都只能生存在中间约3公里的范围内，人竟肆意地从三方面来弄污这有限的生活环境。
海洋污染：主要是从油船与油井漏出来的原油，农田用的杀虫剂和化肥，工厂排出的污水，矿场流出的酸性溶液；它们使得大部分的海洋湖泊都受到污染，结果不但海洋生物受害，就是鸟类和人类也可能因吃了这些生物而中毒。
陆地污染：垃圾的清理成了各大城市的重要问题，每天千万吨的垃圾中，好些是不能焚化或腐化的，如塑料、橡胶、玻璃、铝等废物。它们成了城市卫生的第一号敌人。
空气污染：这是最为直接与严重的了，主要来自工厂、汽车、发电厂等等放出的一氧化碳和硫化氢等，每天都有人因接触了这些污浊空气而染上呼吸器官或视觉器官的毛病。我们若仍然漠视专家的警告，将来一定会落到无半寸净土可住的地步。
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。
写污染的作文 篇11
星期日，万里无云，春风拂面。我和郭悦然一起到郑兴公园去调查水污染的情况。一大早，我们俩相约到了目的地郑兴公园。
走进公园，许多脏兮兮的水就出现在我的眼前，有的水里到处都是垃圾，有的地方水也干了，有的都成了死水，我发现一些被折断的桃花枝躺在水面上。哎……这里的水好脏啊！接着我们又去了胜溪湖公园，这里的水干干净净，风还吹动着水面，站在岸边仿佛自己也在轻轻飘动。此时我想到了郑兴公园的水，比起胜溪湖来差劲的多呢！我们恋恋不舍地离开了胜溪湖公园。通过这次活动，让我知道了郑兴公园是长期不及时清理水里的垃圾造成水污染的，而胜溪湖的水恰恰相反，定期有清洁工人打捞水里的杂物，同时还清理路面卫生，所以一看到胜溪湖公园的水就特别干净、清爽。
回去的路上，我想，我们一定要爱护环境，不要乱扔垃圾，这样才能让我们在良好的环境下成长。
