In the stream next to the road, there is a trash, in the trash next to, there are a lot of garbage: rotten apples, dead mice, Coke cans ... ...

Roadside, people coming and going, bustling, withering. They are talking and laughing, some people eat snacks, the garbage to the direction of the trash to throw; some people through here, smell the stench, clutching his nose hurriedly left; there are people Mamalielie, his face exposed Hated look. But no one is going to clean up the rubbish.

That day, Hasty and Showtime chest wearing a bright red scarf went to school. In the moment after the trash, they stopped, looked at the show, Showtime, said: "Hasty, we clean up the garbage!" Xinxin bent down, rolled up the sleeves, picked up the garbage into the Trash, they are not too dirty, even dead rats, dead cockroaches have not let go.

After the garbage, the winter and winter from the bag out of the pen and paper, touched the back of the head, waved "brush" to write: "civilization - only one step!" And then paste the slogan to the trash Warned passers-by.

I have heard such a story -

In a Korean home, there is a handy paper was blown away by the wind. He chased him all fifteen minutes on the street and threw it into the trash. The reason is not because of their own to bring pollution to the earth.

The earth gives the essence of the material, and in the end, it is from the people that the rebate is rubbish.

Treat the earth is to treat yourself. Save the earth is to save the future. So we want to start from today, from their own to protect our Mother Earth.

Protect the environment by everyone!

在川流不息的马路旁边,有一个垃圾桶,在这个垃圾桶的旁边,有很多垃圾:烂苹果、死老鼠、可乐罐......

路边,人来人往,熙熙攘攘,擦肩接踵。他们有说有笑,有的人吃完了零食,把垃圾往垃圾桶的方向丢去;有的人经过这里,闻到恶臭,捂着鼻子匆匆离去;还有的人一边骂骂咧咧,脸上露出了讨厌的神情。但是就是没有人去清理垃圾。

那天,冬冬和欣欣胸前戴着鲜艳的红领巾上学去了。在经过这垃圾桶的瞬间,他们停下了脚步,看着看着,欣欣说:“冬冬,我们把垃圾清理干净吧!”欣欣弯下腰,卷起衣袖,把捡起了垃圾放进垃圾桶,它们不嫌脏,连死老鼠,死蟑螂也没有放过。

收拾后垃圾后,冬冬从书包里拿出纸笔,摸了摸后脑勺,挥笔“刷刷”地写到:“文明——只差一步!”然后把这标语贴到垃圾桶上,以告诫路人。

我也听过这样一个故事:

在一个韩国人的家里,有一张可要可无的稿纸被风吹飞了。他整整在街上追了十五分钟才追到,然后把它扔进垃圾桶里。原因是不想因为自己给大地带来污染。

大地给予所有人是物质的精华,而最后,它从人们那里得到的回赠都是垃圾。

善待地球就是善待自己。拯救地球就是拯救未来。所以我们要从今天做起,从自己做起,保护我们的大地母亲。

保护环境靠大家!

篇3:11.关注童工问题背后的一对矛盾

全文共 1455 字

+ 加入清单

家庭贫困、乡村凋敝是迫使他们离开家的原因,深层原因其实是区域之间发展不平衡,制造业成本上升,地方执法不严。

江苏常熟服装城黑作坊雇用童工事件,得到了快速查处,事件中的孩子在案件查处完毕、工厂结算报酬后,将被当地政府送回家乡。然而,许多人却开始担忧:送回原籍不会是此次童工事件的终点,童工问题也不可能通过一次次送回原籍而获得根本解决。类似的童工事件究竟该如何善后,让相关部门和关注事件的人们都陷入了纠结。

这些孩子该怎么办?从常熟当地相关部门对服装城展开大规模排查开始,网友们就在各种网络平台上进行了观点交锋:留在当地,这些孩子没有合理合法的依据继续进行劳动、获得报酬;送回原籍,谁也无法保证这些孩子不再成为童工。去留之间,童工们似乎成了一个烫手的山芋。有人认为,应该把选择权交给孩子,让他们自己选择是留在城市,还是回到家乡。但这显然不是什么好办法,其实这个年龄段的孩子,他们的青春应该在校园里,而不是在工厂的流水线上。

在媒体报道中,有一名17岁的小姑娘,坐在挤满高低床的宿舍里,向记者讲述自己的故事。她也曾经是一名童工,现在的她不过是年龄往成年的方向上靠近了一步,迈过了法律规定的16岁的就业门槛,但她所面临的困境与童工没有什么两样——同样来自贫困的西部农村,同样是辍学后外出打工。她的经历告诉人们:童工现象其实长期存在,一批来自贫困地区儿童,他们的基本权益没有得到很好保障。

保障儿童权益,让孩子们健康快乐成长是全社会的共识。童工事件却警示人们:我们对孩子的保护并没有想象中的完善,仍存在死角。上述事件中,孩子权益受到侵害,最直接的原因是企业违法和政府监管缺失。新华社记者调查发现,常熟服装城周边有大量服装业黑作坊,这些黑作坊多存在非法雇佣童工现象。尽管,我国法律有明确规定,用人单位不得非法招用未满十六周岁的未成年人,违者将处以吊销营业执照等处罚。但是,这些黑作坊大多相对隐蔽且无证无照,政府对其管理上存在真空,不仅难以清查,更难以处罚。

监管盲点的存在和违法行为的发生,深层次的原因是发展中的矛盾没能得到有效化解。大量黑作坊雇佣童工的背后是一对矛盾:一方面,类似常熟这样的劳动力密集型产业存在降低用工成本的迫切需要;另一方面,西部贫困地区的部分未成年人,因为各种原因辍学后,希望通过打工离开农村,同时赚取报酬补贴家用。两方面需求的错配,形成了非法雇佣童工的黑色利益链条。各地如果不重视化解这对矛盾,不严厉打击这类利益链,就难以有效遏制非法童工现象。

目前,让童工离开黑作坊,把他们送回原籍,与其说是解救,不如说是解围。如果相关的反思和处置仅限于事件本身,那么事件带来的结果可能只是让这些孩子暂时免于从事与年龄不相称的劳动,而不能彻底把他们从贫困的家庭和凋敝的家乡解脱出来。

家庭贫困、乡村凋敝是迫使他们离开家的原因,再往深层去追溯,背后其实是区域之间发展不平衡的问题、西部乡村留守儿童问题、制造业成本上升问题、地方执法不严违法不究的问题等。这一个个积弊已久、牵涉复杂的问题,归纳起来可以说是发展中的问题,童工现象只是社会发展不均衡的表征。

再穷不能穷教育,再苦不能苦孩子——这句政策口号,许多人耳熟能详。儿童是国家和民族的未来,童工现象这类社会转型发展时期的“次生灾害”,不应祸及这些未成年的孩子。中央明确要求,要始终把儿童发展放在优先位置,各级政府在公共政策制定实施过程中,要优先考虑儿童利益和需求。那么,各地相关部门是不是应该以此次事件为警示,在加快地方经济发展、推进精准扶贫的同时,努力补上那些儿童权益保障漏洞?

Better City ,Better life

优质的城市,优质的生活

Environmental problem has become an important and crucial issue. The abysmal lack of fresh water, the desertification, the green house effect and the extinction of creatures are the main issues in environment.

环境问题已成为一个重要和关键的问题。恶化的淡水缺乏,沙漠化,温室效应和生物灭绝是环境的主要问题。

With each second that passes, a water crisis takes another step closer to reality. Consumption of fresh water has tripled since 1950; and fresh water is becoming a very scarce resource. Agricultural practices, mainly irrigation, account for 67% of world water consumption. Over one billion people worldwide dont have access to clean drinking water. So it is incumbent upon all to respect every drop of water and avoid the generation of waste.

随着每一秒的过去,水危机用其他的方法去接近现实。新鲜水用量自1950年以来已经翻了两番;和淡水已成为一个非常稀缺的资源。农业实践,主要是灌溉,为世界用水量67%以上。全世界十几亿人无法获得干净的饮用水。因此,呼吁所有有责任尊重每一滴水,避免废物的产生。

The soil under our feet is also getting away from us. Removal of the natural vegetation leaves extensive tracts of land devoid of a plant cover and susceptible to wind and water erosion. Finally, desertification is accomplished. Four specific activities have been identified as major contributors to the desertification processes: over-cultivation, overgrazing, firewood gathering, and over-irrigation. The extreme seriousness of desertification results from the great difficulty in reversing or even slowing the process. Once the soil has been removed by erosion, only the passage of centuries or millennia will enable new soil to form. The tree planting is a dominant contributor to the development of the disaster. Another effective measure is to restrain the utilization of the land and to exploit the new technology to improve the productiveness of the arable land.

在我们脚下的土地也越来越远离我们。自然植被因为缺乏土地植被和易受风蚀和水蚀而死亡。最后,荒漠化完成。四项具体活动已被确定为对荒漠化的主要导致的过程:过度农垦,过度放牧,薪柴采集和过度灌溉。荒漠化的极端严重性,导致减缓甚至逆转这一过程非常困难。一旦土壤被侵蚀,只有几百年或几千年的才能抵御,使新的土壤形成。主要控制灾情发展都归功于植树。另一个是抑制土地利用率和利用新科技来提高耕地生产率的有效措施。

Our globe is warming up. GHG gases are the main contributor. Carbon dioxide emissions to air are almost exclusively associated with the conversion of energy carriers like natural gas, crude oil, and so forth. Optimization of energy efficiency and, thus, reduction of CO2-emissions and reduction of other GHG emissions contributed from production processes may be the first to be

discussed. And the mitigation of carbon emissions through the development of alternative projects such as solar or wind energy or reforestation, represents one way of managing a carbon footprint.

我们的地球正在变暖了。温室气体是主要的来源。二氧化碳排放到空气中几乎都是在像天然气,原油等能源载体的转换有关。能源效率,因此优化,二氧化碳的排放和其他温室气体减排贡献减少,生产工艺,第一次将要被讨论。发展减缓碳排放量,如通过太阳能或风能或重新造林的替代项目,代表一个管理方式的碳足迹。

The greed of human beings is using up the plants and animals. Tigers once roamed over most of Asia and we can only see them in the zoo. Whales are once the dominant species in the ocean and now they have got out of our sight because of over-harvesting. We must stop harvesting natural resources to excess and bring them back from the brink of extinction. If we take from the wild we must do it in ways that allow natural populations to recover and last long into the future.

人类的贪婪是使用了植物和动物。猛虎组织一度横跨了亚洲大部分地区,我们只能在动物园里看到它们。鲸是海洋中的一次优势种,现在他们现在已经离开了我们的视线,因为过度捕捞。我们必须停止过度采伐天然资源,从他们来的地方,带来了灭绝的边缘。如果我们在野外,我们必须采取的这样的方式使自然种群的恢复和持续,一直持续到未来很长的时间里。

The earth is not the human’s planet, it is our planet. It’s time to take measures to improve the environment for both humans and other creatures. A safe, clean and sustainable environment depends on more than lip service. Both the government and individuals have the responsibility to minimize direct impacts against the environment. All of us can start planting plants in our home, limiting the use of private cars and using public transportations. And the government should impose necessary standards upon the whole society. The beautiful and vigorous earth will come back soon.

地球不是人类的星球,它是我们的星球。现在是时候应该采取措施改善人类和其他生物的环境了。一个安全,清洁和可持续的环境不是取决于纸上谈兵。无论是政府和个人都有责任,尽量减少对环境的直接影响。我们都可以在我们的家开始种植植物,限制私家车的使用和使用公共交通。政府应强加给整个社会所必需的标准。美丽和活力地球将会很快回来。

篇10:形势与政策论文:城市水环境的问题探讨

全文共 3055 字

+ 加入清单

我国的城市河流和湖泊污染情况是非常严重的,城市河流有不同程度的富营养化问题。以下是小编给大家整理的形势政策论文:城市水环境的问题探讨的内容,欢迎大家查看。

摘要: 随着经济快速发展,城市生态形势压力也与日俱增,水环境问题已成为制约社会发展的大问题,环保基础设施建设严重落后,城市生活污染物未得到有效控制,工业污染源未得到严格治理,农业污染日益突出,部分河段水质受污染严重,河水发黑发臭,完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词:城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分,城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响,我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失,造成了城市生态环境、水环境的进一步恶化。针对这样的情况,我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发,恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型,由于城市人员密集、工业化生产程度高,所以,城市用水需要较高的质量、较大的供水量、稳定的供给,这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高,所以,单纯依靠城市区域的供给和开采往往难于满足城市发展的需要,因此,大众城市往往需要从城区周边或外地调水来满足城市的用水需要,“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方,城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中,在日积月累的大量污染的影响下,城市水环境受到了严重破坏,并且这一现象有蔓延和恶化的趋势,造成水环境的脆弱和生态的破坏,影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个,一是,城市生产和生活中大量污染源渗入地下,造成对地下水资源和水环境的破坏;二是,城市地表硬化导致城市地面下渗量的减少,在大量开采地下水的同时,没有必要的补充,出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本,科学发展

把维护广大人民群众的根本利益作为第一点,把群众最关心、最直接和现实的水环境保护问题为重点,转变发展观念,重视生态文明建设,加快建设资源节约和环境友好社会,走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品,水环境治理应突出重点,优先保护饮用水源,确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩,把COD削减量考核指标纳入到区县水环境治理目标体系中,明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标,即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金,对节能减排效果明显,有一定经济基础,技术条件成熟,符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集,污染来源复杂。为此,河道治理将坚持“先截污、后清淤、先治理、后换水”的原则,周密排查河道沿线污染来源,大力实施清淤、截污、生态护坡、河岸绿化等措施,加强河道水体自净和生态修复功能;在突出截污治理的同时,各区县还将坚持污水处理厂、配套管网同步建设,大力提升现有污水处理厂运行负荷率,妥善解决污水出路,切实提高河道水环境质量。

5、加强协作,落实责任

市水务局于去年成立了河道水环境考核办公室,将清水工程已治理河道纳入考核范围,各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制,有效巩固水环境治理成果。此外,目前市政府已正式批准本市河道水环境实施“河长制”管理意见,即将公布全市主要河道“河长”名单,构建完善的河道水环境管理长效机制,为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述,我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。

中国是一个人口大国。为了解决人口问题,我国政府决定实施独生子女政策。执行一段时间后,许多人不仅看到了这个政策的优点还有缺点。因此,人们开始推崇二胎政策。在我看来,二胎政策是应该实施的。作文

First of all, two-child policy is the gift for some only child. For some families, maybe the parents are only child and they also can have only child. Put aside the loneliness of their child, when their child grows up and they grow older, their child marry with an only child girl accidentally, the burden on their child and his wife is unimaginable heavy. Their child and his wife have to take care of two old couples. Usually, a young couple looking after an old couple is a little difficult; if the pressure increasing twice, how can they stand it. But if their parents have two children, they can share the burden of taking care of their parents. It would be much better.

首先,二胎政策对于一些独生子女来说是天赐的礼物。对于一些家庭来说,也许父母都是独生子女,而他们也只生一个孩子。抛开孩子的孤独不说,当他们的孩子长大了,而他们也变老了,他们的孩子又和一个独生子女结婚,这样的话,压在他们孩子和孩子妻子肩上的压力是不可想象的。他们的孩子和他的妻子不得不照顾两对老人。通常,一对年轻的夫妇照顾一对老人就有点难了;如果压力增加了一倍,他们怎么能忍受呢。但是如果他们的父母有两个孩子,他们就能分享照顾父母的压力。这样会比较好。

Secondly, two-child policy can guarantee the number of Chinese population. As the widely spread of one-child policy, some people have changed their conception about giving birth. If they firmly believe one-child policy, there will be more and more the dink. After several decades, our country will famous for lack of population.

其次,二胎政策可以确保中国的人口数量。由于广泛宣传独生子女政策,有些人已经改变了他们的生育观念。如果他们认同独生子女政策,就会有越老越多的丁克族。几十年后,我国就会以人口短缺而著名了。

In conclusion, one-child policy has out of date. And tow-child policy is needed and necessary. It can solve the problem of nowadays and the future.

总之,独生子女政策已经过时了。二胎政策是必要和必须的。这可以解决当前和未来的问题。

我生在北京城里。小时候,我爬到院里的高楼顶上四下眺望,经常能看到颐和园的佛香阁。几年前,我住在北大畅春园,离颐和园只有数里之遥,从窗户里看佛香阁,十次倒有八次看不见。北京的空气老是迷迷糊糊的,有点迷眼,又有点呛嗓子,我小时候不是这样。在北京城里住,几乎每天都要换衬衣,在国外时,一件衬衣可以穿好几天。世界上有很多以污染闻名的城市:米兰、洛杉矶、伦敦等等,我都去过。就我所见,北京城的情况在这些城市里也是坏的。

但我对北京的环境改善充满了信心。因为这是一座现代大都市,有能力很快改善环境,北京是首都,自然会首先得到改善。不信你到欧美的大城市看看,就会发现有些旧石头房子像瓦窑里面一样黑,而新的石头房子则像雪一样白。问当地人,他们会说:老房子的黑是煤烟熏的。现在没有煤烟,石头墙就不会变黑了。现代大城市有办法解决环境问题有财力,也有技术。到了非解决不可时,自然就会解决。

我现在住的地方在城乡结合部,出门不远,就是乡政府的地面。我家楼下是个农贸市场,成天来往着些砰砰乱响的东西:手扶拖拉机、小四轮、农用汽车等等。这些交通工具有一个共同点:全装着吼声震天、黑烟滚滚的柴油机。因为有这种机器,我认为城市近郊、小城镇等地环境问题更严重。人家总说城市里噪音严重,但你若到郊区的公路边坐上一天,回来大概已经半聋了。

说到环境问题,好多人以为这是近代机器文明造成的,其实大谬不然。说到底,环境问题是人的问题。煤烟、柴油机是糟糕,但也是人愿意忍受它。到了不愿忍受时,自然会想出办法来。知识分子悲天悯人的哀号解决不了环境问题。只要知道一件事就可以解决环境问题:人不能只管糟蹋不管收拾。收拾一下环境就好了,在其中生活也能像个体面人。

上个周末,我和我的家人一同前往美丽的西溪湿地游玩。

虽然那里的优美风景让我们入迷,但是我们也看到了令人震惊的一幕。

那天,我拉着家人的手走了那小巧的摇撸船。我小心翼翼地迈出一步,踏上了摇撸船,一开始还摇摇晃晃的,但坐稳后,船便慢慢地平静下来,摇船者划着桨,平静的水面顿时卷起波纹。可是船一开到开阔的水面,水质则非常糟糕,只见水面不再波光粼粼,而是浑浊的油污漂浮在水面,包装盒和塑料袋等其他垃圾随地可见,原本清澈的水变得浑浊不堪。这时的我想,水这么浑,一定是包装盒的油污流进了水中,所以才会这么脏吧!

在回去的路上,我自言自语地说:“如果所有人都爱护环境,保护河流,那每一处环境都会干净、美丽,每一条河流都会清澈见底!"

让我们一起做五水共治的宣传者和执行者,让我们一起爱护环境,共同守护我们的家园。

【参考译文】如我们所知,我国正面临着越来越大的解决空气污染的压力,因为PM2.5(空气污染的主要指标)不断的刷新纪录,雾霾甚至窒息了我国的主要城市。

三、PM2.5知识拓展:

严重的雾霾,让PM2.5这个数字飞入了寻常百姓家,下面我们一起来了解一下,以便积累考研英语作文的写作素材。

PM2.5的“PM”,是英语“particulate matter”的缩写,意为“细颗粒物”。大家在

家中都看到过这样的现象:一缕阳光射入屋内,光柱中有无数微尘在翻飞,这些微尘就是PM50和大于PM50的颗粒物。桌面上,落了一层灰,那是远远大于PM50的颗粒物。所以PM2.5是无法被肉眼看到的。但其虽小却具有极大危害。PM2.5携带了许多有害的有机和无机分子,是致病之源。细菌是人所共知的致病之源,PM2.5和细菌有得一比。能引发呼吸道阻塞或炎症,使得致病微生物、化学污染物、油烟等“搭车”进入体内致癌,影响胎儿发育造成缺陷,还能通过气血交换进入血管。

小提示:目前本科生就业市场竞争激烈,就业主体是研究生,在如今考研竞争日
