篇1:雾霾又来了
全文共 457 字
+ 加入清单近期,雾霾天气频频发生,越来越严重,也引起了全国人民的注意和关照。中国不少地方把雾霾作为灾害性天气预报。
雾霾是怎样形成的呢?请听我慢慢道来。它是由PM2。5尘粒、烟粒、盐粒等均匀地浮在空中从而形成霾。不过,雾和霾还有本质上的区别。起雾时空气潮湿,出现霾时空气干燥,并且对人体有害无益,长期吸入会导致死亡。
雾霾又是怎样产生的呢?汽车尾气,工业生产排放废气,和鞭炮等都是雾霾的主要来由。少开一次车,少放一次鞭炮。让我们中国人不要再忽视环保。
不过,相对的自我保护也是要有的。为了避免吸入雾霾,雾霾天气切勿开窗。出去旅游,或者游玩时,请戴上口罩。多喝桐橘梗茶,并且适量补充维生素D。还要多喝水,饮食要清淡。
雾霾还会引发许多疾病,如呼吸道疾病、心血管疾病等,各种危害人体健康的大病。
保护自己,与雾霾做斗争是最重要的,雾霾虽然恐怖,但是人们还是想出许多办法与雾霾决战,如:人工降雨等。但是,这毕竟只能小范围短时间地控制雾霾,不是长久之计。所以,大家应该保护环境。
保护环境吧!让这几年的雾霾天气逐渐减少吧!让人们不用因此而死亡!
篇2:雾霾_300字
全文共 370 字
+ 加入清单今天早晨,我朦朦胧胧地起了床。往常,刺眼的阳光早把我耀眼忘我的眼里塞了,喊“疼”它也不肯放过我,丝毫不留情面!可是今天,太阳公公好像成了一个受风寒的小姑娘,微弱的阳光,让人怀疑是否天亮。
刚起床,妈妈闻声箭步跑过来,往我脸上戴了一样布制品的东西。我本能反应挣脱了它,妈妈急忙抚上:“今天是雾霾天气,有了PM2.5,严重污染了环境,所以得好好保护”我用余光看了下去这布制品原来是防PM2.5的口罩。
吃完早饭,我像往日一样读起了报,平常我是不留意天气的,今天异常地瞧了一下“哇!”因为雾霾天气,汽车追尾可不少,我一下担心起出门开车上班的爸爸有没有事。
“咳咳!”承受不住了!在口罩里呼吸又闷又憋,呼出去的是热气,吸进去的还是热气,不会吸了二氧化碳吧?总之是又闷又憋!想呼吸外面的“鲜美”的空气,可是又怕PM2.5!
唉!雾霾呀,雾霾你可把我们害惨了!
篇3:走出雾霾
全文共 1084 字
+ 加入清单又是霾!”我望着天空中灰色的霾,心灰意冷地埋怨,带上口罩。
我走出家门,行走在被雾霾包围的小路上,思考着雾霾形成的因由。
邻居王萌瑶刚从书店出来,手捧一本百科书,向我走来。我走上前去,向她道出了困解我已久的问题。
“霾污染主要人为污染源,一次和二次颗粒物的形成,霾污染的主要组成和去向。主要人为污染源是燃煤、工业和汽车尾气。秸秆燃烧是暂时和局部的污染源;扬尘和沙尘主要造成的是粗颗粒物的污染,容易重力沉降和干/湿沉积。沙尘暴有细颗粒物污染问题,但干燥且持续时间较短。从污染源直接排放的烟尘或碳黑类细颗粒物,被称为“一次颗粒物”,也较容易重力沉降和干/湿沉积。但有一部分可能通过其界面的物理化学过程和二次细颗粒物相关。
燃煤、工业和汽车尾气中的气态污染物:二氧化硫、氮氧化物和碳氢化物(大量是VOC~易挥发有机化合物),会经历大气输送和化学过程。图中“hn”表示阳光辐射。夏日氮氧化物和碳氢在烈日下可以光化学反应,导致臭氧(O3)浓度高企和霾污染,灰色程度较轻。出国留学网二氧化硫和氮氧化物转化为硫酸滴、硫酸盐、硝酸滴和硝酸盐,是主要的吸湿性强的“二次无机细颗粒物”。碳氢化物经过物理(凝并聚合等)和化学过程,会形成可溶性“二次有机细颗粒物”。国内外大量研究成果表明,重霾污染中pm2.5的主要成分都是硫酸盐、硝酸盐和可溶性有机碳,它们是重霾污染的主凶。细颗粒物干/湿沉积效率很弱,大部分会因气流输送造成区域性污染问题。”
我点点头,望着远处的工业烟囱,陷入了无言的沉思。王萌瑶也许猜到了我的心思,继续道:
“治理雾霾最主要的方法是减少排放。目前各种化石能源的大规模使用是造成雾霾天气的最主要原因。要想从根本上解决雾霾问题,最有效的方法就是减少排放。大家想想,发电需要燃烧煤,而实际上被燃烧的煤只有不到30%被转化成了电能,其余的都被排放了。汽车、轮船等机械需要石油,同样的,发动机也只是将不足30%的石油转化成了动力,其余的也都被排放了。也就是说我们使用能源是“大手大脚”的,利用的少,排放的多。减少能源的使用是不现实的,而清洁能源远不能满足需求,且价格昂贵。如果现有能源能利用70%,而排放30%的话,环境问题与能源问题会同时得到解决,人类社会也会得到可持续的发展。目前,网络上披露了一种非传统的发动机,是中国人发明的,名叫“往复式转子发动机”,有望实现人类的这一愿望。期望这种机械能早日面世。还有,就是多植树,才能有效地治理雾霾。”
我再一次的点点头,当打开家门时,我将头一转,望向灰蒙蒙的雾霾,突然看到了一束阳光穿透了雾霾的束搏。我笑了,因为不久的将来,一定会看到蓝白云蓝天。
篇4:优秀作文:在说雾霾
全文共 1297 字
+ 加入清单不知从何时起,人们开始关注天气,每天一早,第一件事就是看看天空,如果出了太阳,就会不自觉地展露笑容,如果阴霾横行,就会无奈地叹息一声,该干什么还干什么,只是心情沉闷,眉头紧锁。只盼着老天发个脾气,来一阵风,下一场雨,冲走这晦气。可是,这就象物质不灭定律,这阴霾还在大气中,只是临时躲避起来,从东来到了西,等老天平静了,他还会来,这个瘟神,还真的很难送出去。
上网搜寻,说了好多雾霾的危害,说是比03年的非典还严重,非典还能隔离,还能躲避,还能治疗,可这雾气,谁能挡住不让它流动?谁能把它过滤干净?有的说,过几年肺癌,心脏病会有更高的发病率,想想还真不是危言耸听。
就拿今天来说,从早上到晚上,整整一天,能见度不过十几米,山朦胧,树朦胧,高楼也朦胧,一切都在雾霾中,这雾霾,打不走,散不开,象个幽灵,多少有毒物质掺杂其中。人饿了可以挺,冷了可以挺,可呼吸怎么能暂停?哪怕几秒钟,毒菌们在你呼吸时悄悄钻入身体里,他们在体内兴风作浪,腐蚀你健美的肌肤,吞噬你健壮的生命。可你却任凭它的肆虐,无可奈何,无能为力,真是可怜。可这,又能怪谁呢?怪又有何用?每一代人有每一代人的使命,也许,我们这一茬人,享受了先人没有的物质文明,也要为这文明付出代价了。
雾霾既然是人为造成,相信人也一定能消灭它。但这需要时间,阴霾不是一朝一夕形成的,这几十年来,多少外国企业在华投资办厂,仅美国听说就有几万家工厂搬到了中国,世界上的国家加起来有多少,中国为了发展经济自己的企业又增加了多少,国有钢厂,煤矿不说,那些小钢厂,小煤窑又有多少,谁能数得清,工厂排放废气污水,哪个按要要求执行,都是上有政策,下有对策,九百六十万平方公里的土地,哪禁得住这样的折腾,糟蹋?如果人们拿着用损害环境换来的钞票,出入高级宾馆,饭店,享受着现代文明,可出来呼吸着有毒气,喝着被污染的水,吃着有毒食物,健康没有保障,生命受到威胁,GDP再高又有何用?
据说,我们的污染源源主要是煤,由于中国的能源结构以煤为主,因此中国的电力工业是以燃煤火电为主的,而我国的用电量年年攀升,其中煤电占70%多,美国是50%,日本为25%,欧洲国家用的更少,再说钢,近几年钢产量不断提升,就我们附近,就有一钢厂,前几年建的,虽然也吸纳了不少农民工就业,但那又粗又高的大烟圈,一年365天,一天24小时,呼呼的冒着黑烟,四处扩散,205国道不分白天黑夜,烟尘乱舞,早已变得狼狈不堪,废水乱排乱放,几个村庄的土地受到污染,听说距工厂最近的那个庄,已有十多人得了癌症,也有人反映过,可都是百姓呼声,谁听,最后也是不了了之,一叶落而知秋,管中窥豹,可见一斑。 冰冻三尺,非一日之寒,污染的量积累到一定程度,导致了空气质量的改变,再返回可不那么简单,也许要十几年,甚至几十年的不懈努力,才可见些成效。看来,发展工来,环境污染,也许这是必然。
雾霾,已严重影响了我们的生活,损害了我们的健康,如果再不加大治理力度,后果不知何想。现在,清新的空气,干净的土地,碧水蓝天。这也成了雾霾地区人们的大梦,这个梦何时成成真,人们在等待,在祈盼。相信,总有一天,这个梦会实现,不是今天,就是明天。

篇13:雾霾源
全文共 945 字
+ 加入清单近年来,雾霾越来越严重,雾霾形成原因成了中国不少人关注的事,目前已完成了9个大气污染防治重点城市的源解析工作,其中北京、杭州、广州、深圳的首要污染来源是机动车,石家庄、南京是燃煤,天津、上海、宁波分别是扬尘、流动源、工业生产。
雾霾形成原因
(一)自然气候是影响城市霾日数的首要原因
大范围雾霾天气主要出现在秋冬季节冷空气较弱和水汽条件较好的大尺度大气环流形势下,近地面低空为静风或微风。因此,山、河谷地区(山西的部分城市、湖南长沙等)、平原河湖地区(如南京、合肥、杭州等)更易形成雾霾天气,而干燥多风地区则不易形成。如呼和浩特和乌鲁木齐2012年霾日数为0。本次北京雾霾天气主要是遭遇了罕见的逆温气象条件。
(二)“三高”的经济发展方式是近年来中东部地区霾日数增加的主要原因
2009年我国千美元GDP能耗(2000年美元不变价,下简称单位能耗)约0.77吨标准油,是世界平均水平0.31吨的两倍,同年美、英、日的单位能耗分别为0.19、0.12、0.1吨标准油。尤其是我国第二产业能耗较高。2010年我国三次产业结构为10:47:43,但三次产业及其与居民生活的能源消费比例为2:71:16:11。比产业能耗结构更突出的问题是能源结构。2010年我国能源消费结构中煤炭(其中49.5%用于火力发电)、石油、天然气、电力(包括水电、核电、其他能发电,不含火电)比例为71.9:20:4.6:3.5(下文同此口径),同期世界煤炭消费占比不到30%,我国清洁能源使用比例明显偏低。
(三)大气污染区域化和生活方式高碳化是一些大城市霾日数增加的重要原因
2011年,北京市单位能耗约为0.32吨标准油,三次产业结构为0.9:24:75.1,能源消费结构中煤炭、石油、天然气、电力比例为27.1:32.6:14.4:25.9,基本达到世界大城市标准。北京市环保局数据显示,今年1月影响北京PM2.5污染物(霾天气的重要成因)的首要原因是北京周边地区的影响(24.5%),其次是机动车直接和间接排放(约22%)。在长三角和珠三角的部分城市,部分污染物的外来源贡献率达到40%。
霾日数增加不仅是“天灾”,也是大气污染的“人祸”,在人口、产业密集的大城市更易发生,影响也更大。治本之道在于多管齐下,积极应对大气污染。
篇14:关于雾与霾的作文
全文共 978 字
+ 加入清单当云落到地上,便会变成雨,倘若不落地,则便是雾了。最近总是“满地云”,可却非雾非雨,倒却是雾的同胞兄弟——霾。
雾与霾,虽说同胞,长得确乎几分相似,甚至还有词叫作雾霾的,但是两者的区别还是蛮大的。说起雾,人们也许会联想到“雾都”伦敦。雾是悬浮于空中且接近于地面的细微的水滴组成的一个庞大的群体,也可以说是飘在地上的云了。雾虽然会降低能见度,但它通常只出现在清晨,太阳一照基本就消逝了。只要人们不长期处在浓雾中,它一般不会向人痛下毒手,反倒给人一种雾蒙蒙的飘逸舒畅的感觉。但它的弟弟却不怎么温和,动起刀子来是杠杠的。它与哥哥不同构成中除了一部分水汽,还有大量的PM2。5,说白了就是飘在空中的浓浓的灰尘。它可以在一天中的任何时候出现,对人们产生相当大的危害。由于其部分烟尘颗粒可进入人的肺部,可以引起呼吸系统、循环系统的诸多疾病,且由于能见度低在交通方面也扼杀了许多无辜的生灵。就说刚刚提到过的雾都伦敦吧,1952年12月5日开始,伦敦连续数日空气寂静无风。当时伦敦冬季多使用燃煤采暖,市区内还分布有许多以煤为主要能源的火力发电站。由于逆温层的作用,煤炭燃烧产生的二氧化碳、一氧化碳、二氧化硫、粉尘等气体与污染物在城市上空蓄积,引发了连续数日的雾霾天气,据史料记载,从12月5日到12月8日的4天里,伦敦市死亡人数达4000人。而在12月9日之后,由于天气变化,毒雾逐渐消散,但在此之后两个月内,有近8000人因为烟雾事件而死于呼吸系统疾病。足见霾的杀伤力之强。
雾与霾都是自然现象,但在霾的成因中,却又有很大一部分缘自人类自身。霾的形成与污染物的排放密切相关,城市中机动车尾气以及其它烟尘排放源排出粒径在微米级的细小颗粒物,停留在大气中,当逆温、静风等不利于扩散的天气出现时,就会形成霾。
最近国内大气污染比较严重,人们也颇受了其苦。解决方法呢也倒是有的。治理雾霾最主要的方法是减少排放。在这点上,人类可以控制工厂的废气排放。减少能源的使用是不现实的,而清洁能源远不能满足需求,且价格昂贵。人类能做的,就是尽快制造出更节约资源的机器。还有,当然是植树造林了。
霾,并不可怕,它只是在雾里掺了灰罢了,倘若人们能够同心合力,从小事做起,从自己做起。相信在我们的努力下,天,还会蓝,视野,还会清晰,满地的乌云终会变成满地白色的清纯的水雾,或是万里晴空。

常言道“秋冬毒雾杀人刀”。我们看得见、抓不着的“雾霾”其实对身体的影响较大,尤其是对心脑血管和呼吸系统疾病高发的老年人群体。
1.对呼吸系统的影响。霾的组成成分非常复杂,包括数百种大气化学颗粒物质。其中有害健康的主要是直径小于10微米的气溶胶粒子,如矿物颗粒物、海盐、硫酸盐、硝酸盐、有机气溶胶粒子、燃料和汽车废气等,它能直接进入并粘附在人体呼吸道和肺泡中。尤其是亚微米粒子会分别沉积于上、下呼吸道和肺泡中,引起急性鼻炎和急性支气管炎等病症。对于支气管哮喘、慢性支气管炎、阻塞性肺气肿和慢性阻塞性肺疾病等慢性呼吸系统疾病患者,雾霾天气可使病情急性发作或急性加重。如果长期处于这种环境还会诱发肺癌。
2.对心血管系统的影响。雾霾天气空气中污染物多,气压低,容易诱发心血管疾病的急性发作。比如雾大的时候,水汽含量非常的高,如果人们在户外活动和运动的话,人体的汗就不容易排出,造成人们胸闷、血压升高。
3.雾霾天气还可导致近地层紫外线的减弱,使空气中的传染性病菌的活性增强,传染病增多。
4.由于雾天日照减少,儿童紫外线照射不足,体内维生素D生成不足,对钙的吸收大大减少,严重的会引起婴儿佝偻病、儿童生长减慢。
5.影响心理健康。阴沉的雾霾天气由于光线较弱及导致的低气压,容易让人产生精神懒散、情绪低落及悲观情绪,遇到不顺心的事情甚至容易失控。
6.影响交通安全。出现霾天气时,视野能见度低,空气质量差,容易引起交通阻塞,发生交通事故。

Pollution Haze
Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.
Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.
Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.
In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day.
亲爱的比尔,
我很高兴收到你的来信,谢谢你关心我的天气和我的健康。现在我想告诉你们一些关于雾霾的事情。
自去年冬天以来,雾霾已经发生了很多次。这对我们的日常生活造成了很大的伤害。只是因为发生了许多交通事故的烟雾天气,越来越多的人去看医生因为烟雾造成的严重的疾病,很多的航班不得不推迟,许多人不得不留在家里,以免造成的空气有毒烟雾。
人们已经意识到雾霾带来的巨大危害以及保护环境的重要性。全国各地的人们都在采取措施减少雾霾天气。政府建议人们去上班或上学,比如公共交通,比如公交车和地铁。我们也应该种更多的树。
根据我的说法,我将骑自行车或步行去上学,我不会把垃圾扔到任何地方。此外,我会告诉我所遇到的人尽可能地保护环境。你能告诉我一些好主意吗?我期待着你的答复。

打从科技的发展,社会已经变得现代化,人们充分利用高科技来追求更多的利润。虽然政府已经注意到了人们对环境所做的事情这个问题,但是他们仍然不能阻止被污染环境的所带来的后果。
Many years ago, the most prominent problem of the polluted environment is that the river and the water were changed their color, some fish even died for the polluted river. Now the situation becomes ever worse, lately, in the big city, like Beijing and Shanghai, people are annoyed by the bad weather. It is not the rainy day, but the haze around the sky, there is no way for people to run away for it. The haze contains toxic elements, people breathe it and hurt their bodies.
很多年前,环境污染所带来的最突出问题时河流和水的颜色被改变,一些鱼甚至死于被污染的河流。现在这样的情形变得更加的糟糕,最近,在大城市,比如北京和上海,人们受困于糟糕的天气。并不是因为雨天,而是因为雾霾包围天空,人们无处可逃。雾霾中含有有毒的元素,人们呼吸着雾霾,损害着他们的身体。
The haze problem is the result of people’s pursuit for the profit, what people did to the environment now has been paid back by the environment. Now people have realized the revenge from the nature is so huge, protecting the environment is the main task. No matter how bad the environment is, people still need to do something to fix their mistake.

+ 加入清单雾霾天气和我们的环境受到污染有很大的关系,只有当我们行动起来,保护环境,保护我们的家园,才能远离雾霾,让我们的家园恢复它原本的美好,才能让我们的生活越来越舒适!
在一次偶然的机会下,我从表叔那得知了《穹顶之下》这部纪录片,然后在班上就把这部纪录片给看完了,这部纪录片给我了极大的感受。
柴静是以她女儿的故事做开头:“听到她的心跳的那一瞬间,我觉得对她没有任何期望,健康就好。但是,她被诊断为良性肿瘤,在出生之后就要接受手术。”我被惊住了,一个刚出生不久的小婴儿就要接受大手术,雾霾让柴静的女儿出生前就患上了病,所以柴静以一个母亲的身份与雾霾开始了斗争,正如她所说,这是一场一个母亲和雾霾之间的私人恩怨。
其中让我印象最深的一幕是柴静正在采访一个六岁的小女孩:那个小女孩没有见过星星,没有见过白云,连蓝天也只见过蓝一点点的。现在,孩子们想看见星星是一种奢望,成人们想看见曾经的天空是一种奢望,白云也是曾经的回忆罢了。这,是因为什么?是因为我们自己罢了。
雾霾是什么?雾霾从哪来?我们怎么办?这是柴静提出的三个问题。
雾霾是什么?柴静说:它们是一些空气动力学直径小于2.5微米的颗粒,我们看不见它,因为肉眼能看到的颗粒物,最小的也是它的20倍,这是一个看不见敌人的战争。一个看不见敌人的战争,是危险的,是可怕的。而且这些敌人在我们呼吸的时候,它们都在。
雾霾从哪来?来自于我们的日常生活,中国的PM2.5,百分之六十来自于燃煤和燃油,也就是化石能源的燃烧。还有一部分是来自于汽车尾气、加油站废气泄漏……我们的煤怎么了?现在中国烧的煤比其他所有国家加在一起烧得都要多,而且我们烧的是劣质煤、褐煤、没有清洗过的煤!我们的油又怎么了?我们的油大部分烧在车上,我们的车在十年之间增加了将近一个亿,光北京2010年一年我们增加的车是多少呢?八十万,排成一条能从北京排到深圳,再从深圳排回来。
我们怎么办?我们该拿雾霾怎么办?让我们的曾经湛蓝的天空回来很简单,就要看我们有不有这个决心。有个APP软件可以随时查看你周围的重污染工厂,你可以举报;你看到周围的餐厅有污染情况,可以拨打12369举报。但如果我们不说,12369永远只是一串数字,但如果我们说,那么12369就有可能是让天空变回湛蓝的原因之一。
我们该拿雾霾怎么办?很简单,从你做起,从大家做起,从有关部门做起,一起保护家园,让雾霾从此消失。
