1. 海洋被污染了会怎么样

具体如下:

1、垃圾污染

工业冷却水和工程残土、垃圾及疏浚泥等。前者入海后能提高局部海区的水温,使溶解氧的含量降低 ,影响生物的新陈代谢,甚至使生物群落发生改变;后者可破坏海滨环境和海洋生物的栖息环境。

2、噪声污染

利用天然声纳进行导航和捕猎,让无脊椎动物深受其害。勘探船产生的声音污染对头足类动物以及其他海洋动物的生存造成不利影响。

3、过度捕捞

人类的捕鱼活动导致海洋中生存的某种鱼类种群不足以繁殖并补充种群数量。现代渔业捕获的海洋生物已经超过生态系统能够平衡弥补的数量,结果使整个海洋系统生态退化。

4、冰川融化

由于冰盖的融化,奇特的低盐度海水正在慢慢的消失,截止到2002年, 96%的低盐度栖居环境已经消失殆尽。大部分以冰川径流作为供水源的地区将会发生严重的缺水危机。

5、石油泄漏污染

石油污染在海洋表面形成面积广大的油膜,阻止空气中的氧气向海水中溶解,同时石油的分解也消耗水中的溶解氧,造成海水缺氧,对海洋生物产生危害,并祸及海鸟和人类。

2. 海洋污染到了什么程度

就目前的开采技术而言,基本上无论是哪种方法,都是促使可燃冰中天然气与水的分离,要促使其分离,必然要改变其温度及压力环境,这样就可能会产生一系列不可预知的环境问题,如温室效应的加剧、海洋生态的变化及引起地质灾害的可能。

可燃冰的成分主要是甲烷,甲烷是一种强温室气体,对大气辐射平衡的影响仅次于CO2。

目前探明全球可燃冰储量的甲烷是大气圈中甲烷的5000倍,在开采的过程中,即使如此巨大的甲烷总量哪怕是0.5%进入大气层,对全球变暖的影响也是难以估量的,如果开采中稍有不慎,则必然会加剧温室效应。在海洋中开采可燃冰带来的环境问题更多,一方面甲烷如果直接进入海水中,则会很快发生微生物的氧化反应,从而会改变海水的化学属性,如果大量进入,其氧化过程中会消耗海水中大量的氧气,使得海洋缺氧,这样势必会加速海洋生物的死亡;

另一方面大量直接进入海洋的甲烷还可能会加速海洋气化及海啸,导致海水加速流动及气压卷吸,会严重危害海面船只及作业平台的安全,甚至强对流的海水会直入空中,影响航空及陆地建筑的安全。

在开采可燃冰的过程中,会分解大量的水,这些水会稀释岩层空间,使得地层结构稳定性变差,容易引发地质灾害。

在海洋环境中,无论是减压分解还是激热分解,都会导致海底陆坡区的稳定性下降,严重则会发生海底坍塌,如毁坏海底输电或通信电缆和海洋石油钻井平台等设施。

就目前的开采方法来看,无论是哪种方法都不能单独实施,必须是几种方法的结合,如果使用二氧化碳置换法、化学试剂减压法与其他方法的结合实施,则势必会产生新的问题,这些化学试剂及二氧化碳注入到地下后,会严重污染地下水源。

3. 海洋被污染的后果

  来自长江和省内6大水系所携带的大量工农业废水和生活污水排入海中,使我省87%的近岸海域受到不同程度的污染,基本已无I类海水,沿海特别是河口海水中无机氮和无机磷严重超标,海水中磷酸盐合量在沿海省、自治区和直辖市中排居首位。

近岸海底沉积物中氮、磷超标严重,成为海水二次污染的潜在危害源。另外,个别海域(如杭州湾和舟山海域)船舶排污及碰撞漏油,海上石油开采溢油等加剧了近岸海域的污染,有机污染和重金属也对海水水质产生明显的影响。

  海洋灾害频繁——每年发生大小赤潮近20次

  我省是风暴潮、赤潮等海洋灾害最为严重的省份之一。每年因台风给我省海洋渔业造成的直接经济损失在数十亿元以上。由于海水水质下降和富营养化,导致赤潮灾害发生的频率逐年上升,给我省的海洋经济带来巨大的损失,近年来,每年发生的大小赤潮灾害近20次,年直接经济损失达数亿元。

  围海造地——许多珍稀濒危野生生物绝迹,破坏生态

  我省沿海滩涂资源359.04万亩,主要分布在钱塘江和杭州湾两岸,以及各海湾。由于不合理的围海造地,使沿海自然滩涂湿地面积缩减,不仅破坏了多种鸟类的栖息地,也使重要的经济鱼、虾、蟹和贝类生息、繁衍场所消失,许多珍稀濒危野生生物绝迹,而且大大降低了滩涂湿地调节气候、储水分洪、抵御风暴潮、净化地表径流及护岸保田等的能力,同时改变了海区的水动力方向,加速了航道和港口的淤积。

  海洋食物链已经遭到严重破坏——经济鱼类资源大幅度降低

  随着海洋开发话动的增多,海洋生态环境遭受破坏,使生物多样性衰减,某些生物种类已近绝迹,传统的经济鱼类资源大幅度降低,再也形不成渔汛,海洋食物链已经遭到严重破坏。东海生态系统中的主要经济物种严重衰竭,整体结构发生显著变异,系统内部自我调节的能力受到严重损害。

  请勿将废水和生活垃圾直接排入海中

  造成海水如此恶劣的污染源主要有陆上和海上两大类。陆上污染源主要是工业污水、居民的生活废水以及农田中使用的农药通过河流流入大海,沿海企业和居民直接将污水和废水排入海中。海上的污染源主要有船舶上和港口的油污和生活废水,养殖场、海洋工程、海岸工程产生的污染。

为了使我们的海域不再受污染,省有关部门已经颁布了一系列的政策法规对海域污染进行了治理。同时也提醒沿海的居民不要将废水和生活垃圾直接排入海中,出海的渔民应该把该回收的都要回收,而不要一丢完事。

4. 海洋被污染后的现象

污水给鱼儿带来的只有死亡,如果人们吃了被污染的海里的鱼,大多数会生病的就海洋污染而言,是个大问题呀!海洋生物物种一旦遭难,生态就会失去平衡,也许会就此产生新物种来适应这种恶劣环境也说不定。但最大的可能就是愈演愈烈,最终地球将会成为一颗“死亡星球”。到时我们就惨了,还是现在好好保护吧。

5. 海洋被污染了会变成什么颜色

海水蒸发不会携带核污染。

核污染通常指放射性物质的泄漏,这些物质会在水中沉积或溶解,但研究显示,海水在蒸发过程中会过滤掉有机和无机颗粒物,以及放射性污染物,因此在海水蒸发的过程中,核污染物质不会被携带到空气中。

核污染和环境保护是全球的热点话题,应该保护环境,避免污染,同时科学研究也应该继续进一步发展,不断寻找更好的防治污染的方案和技术,保障人类的环境和健康。

6. 海洋被污染了用英语怎么说

Pollution

Sea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.

I need to describe the problem. Our ship currently dumps all its rubbish into the sea.It's easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.

I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly. A case in point is that we should stop providing plastic bags.

We must act now before it is too late!

海洋污染英语作文二:Reduce Sea Pollution

Several problems are caused by the non-organic substance. We ought not to pour wastes into the ocean, because it not only pollutes the ocean, but also lead to a series of harmful consequence. First and foremost, the non-organnic things, for instance, plastic bags, may kill fish and whales. Second, fishes can't digest them. Finally, some of the rubbish is inherently toxic, they will posion marine life.

We must take actions to protect our whale from dying. One thing we should do is creating a better system of disposing of rubbish. Another effective solution is making ships environmentally friendly. Sypermarkets shall stop the giving of plastic bags.

As a captain of the ship, you should spare no efforts to think more helpful ideas and stop dumping rubbish from now on. We all need to raise awareness of these problems. It now becomes necessary that we must act now, before it is too late!

海洋污染英语作文三:Sea pollution

Between 75 and 80% of marine pollution is caused by land, particularly agriculture. 30% of this is from the atmosphere. Around 12% of the pollution is caused by maritime transport.

In South America, 98% of domestic wastewater ends up, untreated, in the sea. The countries along the Mediterranean Sea throw 50 million tons of waste into it every year and the Chinese throw 60 million tons of waste into the Yellow sea daily. Over half of the hydrocarbon discharge comes from continents, 5% comes from oil tanker accidents, 20% comes from waste and other ship-related accidents, 4% from sea exploitation and 11 to 15% is due to natural causes. Accidental pollution through hydrocarbon is significantly decreasing and only represents a small percentage of waste through degassing estimated at between 1.5 and 3 million tons of oil a year. In 2003, according to the WWF, between 0.7 and 1.3 million tons of oil were spread by degassing in the Mediterranean. According to the Ifremer (the French Institute for Exploitation of the Sea), coastal water pollution cost the world economy almost 12.8 billion dollars in 2006.

Marine pollution is the result of products being thrown into seas and oceans, mostly by mnkind: domestic waste (sewage and rubbish, pollutants in runoff water...), industrial waste (hydrocarbons, metals, synthetic chemical and organic substances, radionuclides...) and agricultural waste (fertilisers, pesticides...).

This includes water pollution and marine sediments, and more generally all damage to marine ecosystems caused by harmful substances being discharged into the sea, either by their nature or their quantity.

海洋污染英语作文四:Sea Pollution

Marine environment is one in water, seawater tolerance hydrolyzate and suspended solids, seabed sediment and marine organisms, including complex systems. Ocean rich biological resources, mineral resources, chemical resources and power resources is an indispensable resource treasure house of human beings, with human survival and development of the relationship very close.

The main objective of the current marine conservation is to protect the living marine resources, so as not to failure, in order for human sustainable use. In particular, give priority to protect those valuable and critically endangered marine life. According to the UN for investigation, due to overfishing, accidental capture and killing of non-target to allow hunting of marine, coastal shoreline construction, mangrove deforestation, widespread marine pollution, at least the world's 25 most valuable fishery resources depleted, whales, sea turtles, manatees and many other marine animals face extinction risk. Is expected that with the expansion of the scale of ocean development,Marine living resources are likely to cause more damage.

The task of the first marine protected right to stop over-exploitation of living marine resources and secondly to protect the habitat of marine life or habitat, in particular, their migration, spawning, foraging, avoiding predators coast, tidal flats, estuaries, coral reefs, it is necessary to prevent the heavy metals, pesticides, oil, organic and easy to produce nutrients such as eutrophication of marine pollution. Preservation of the marine living resources of the natural regeneration capacity and water purification capacity, preservation of the marine ecological balance, to ensure sustainable human development and utilization of the oceans.

海洋污染英语作文五:Polluting the seas

The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

海洋污染英语作文六:Sea Pollution

From the overall situation, wastewater emissions growth speed. Is expected in 2000 will reach 666 tons. City life sewage volume will continue to increase, in 2000 reached about 783 tons. The wastewater of low (estimated at 20% ~ 30%),most of untreated wastewater directly or indirectly discharged into the water body, the serious pollution of water resources. China's seven major river systems in nearly half of serious pollution, city section of river water qualitygenerally exceed the standard 86%. The polluted water, more serious is the Huaihe, Haihe, Liaohe, Songhua River, the downstream Yangtze River and the Pearl River Delta industries in developed region.

River city section of riverpollution, heavy on the river, north to south. In 1990, 94 river city section of evaluation, 65 are subject to different degrees of pollution, accounting for 69.1%, the main pollutants ammonia nitrogen, volatile phenol and oxygen consumption of organic matter. According to the survey, 700000000 peopledrinking water the Escherichi a coli exceed the standard, 164000000 people drink organic pollution of water, 35000000 people nitrate drinking water exceed the standard.

Huaihe is one of the most polluted rivers. Huaihe in the evaluation of the 2000kilometers of the river, 78.7% river does not meet the drinking water standard,the 79.7% section does not meet the standard of fishery water, 32% do not meet the standard of irrigation water. According to statistics, the national 3000 heavily polluting enterprises, enterprises of wastewater discharge of industrial pollution,Huaihe River Basin accounts for 160. A sewage units 1.55 182 towns within the basin, industrial wastewater emissions of 1610000000 cubic meters, 700000000 cubic meters of urban living water emissions. Huaihe sewage irrigation farmland,causing serious crop production; in 1989 the occasion of the Spring Festival, the sewage discharge upstream gate opening, the tap water in Huainan, Bengbu twocity is seriously polluted and not drinking, Huaihe basin, the public drinking watercrisis, people Voices of discontent.

Huaihe basin in many areas of cancer incidence rate than the normal area than 10 times to hundreds of times, some villages in 2/3 of hepatomegaly. At the same time, due to the pollution of the estuary, anadromous fish resources has been damaged, the sharp drop in output, part of the in

7. 海洋被污染的绘画

海上燃犀图,又称《海燕图》,是中国南宋著名画家赵伯驹所绘(约活动于公元1254年至1292年间)。赵伯驹是南宋时期的一位重要花鸟画家,他深受文人雅士的喜爱,被誉为“吾国之鸟兽工笔之始祖,其技惊天下而无出其右者”。他的画作以构图严谨、笔墨细腻、形神兼备而著称,海上燃犀图是他的代表作之一。这幅画刻画了海上巨兽燃犀,和一支在它身旁飞舞的海燕,气势恢弘,极具生命力,被认为是中国古代画的巅峰之作。现今,海上燃犀图收藏于台湾故宫博物院。

8. 海洋污染我们该怎么办

防止海洋污染的办法有。促进海洋开发与环境保护协调发展,立足于对污染源的治理;对海洋环境深入开展科学研究;健全环境保护法制,加强监测监视和管理;建立海上消除污染的组织,大力宣传保护海洋知识;加强国际合作,共同保护海洋环境。

9. 海洋污染怎么处理

1、加强宣传,提高全社会海洋生态环境保护的意识。

2、沿海农田、林场施用化学农药,必须执行国家农药安全使用的规定和标准。

3、加强建设项目对海洋生态环境影响的整体评价。

4、坚决抵制某些工厂向海洋中投放各种化学废水,如果不尽快阻止,海洋会由蓝色变为死气沉沉的灰色。

5、严格管理乱扔垃圾的现象,乱扔垃圾者应被批评教育和罚款相结合。

6、生活污水、工业废水的排放,会带给海洋大量的病菌和有毒物质,导致海水富营养化。要想改善海洋环境,必须重视排放问题。

7、当离开海滩时带走自己的垃圾,并且帮助收走他人遗留的废弃物,积极参与全球性的海滩清洁、海洋无垃圾的活动。

8、建立渔民准入制度,不是所有的人都可以从事海上捕捞作业,在优先渔民入渔的情况下,严格控制把关附近农民加入渔民队伍。

9、不要将贝藻养殖业作为影响旅游环境的障碍来清除,而要鼓励其发展。

10、不要破坏珊瑚礁,海藻丛等海洋生物生活的地方,破坏它们可能会破坏海洋生命链。

10. 海洋被污染了鱼儿会怎么样

  一、石油危害可分为三个方面:  1、一是油气污染大气环境,表现为油气挥发物与其它有害气体被太阳紫外线照射后,发生理化反应污染;或燃烧生成化学烟雾,产生致癌物和温室效应,破坏臭氧层等。  2、二是污染土壤,这里我们不必多说明,大家都知道石油污染土壤的地方,寸草不生。  3、三是污染地下水,我们现在生活的水资源被污染,以至于地方性癌症村屡屡皆是,这石油污染地下水的恶果是日日严峻。  二、石油污染是指石油开采、运输、装卸、加工和使用过程中,由于泄漏和排放石油引起的污染,主要发生在海洋。石油漂浮在海面上,迅速扩散形成油膜,可通过扩散、蒸发、溶解、乳化、光降解以及生物降解和吸收等进行迁移、转化。油类可沾附在鱼鳃上,使鱼窒息,抑制水鸟产卵和孵化,破坏其羽毛的不透水性,降低水产品质量。油膜形成可阻碍水体的复氧作用,影响海洋浮游生物生长,破坏海洋生态平衡,此外还可破坏海滨风景,影响海滨美学价值。石油污染防治,除控制污染源,防止意外事故发生外,可通过围油栏、吸收材料、消油剂等进行处理。  三、防治治理  1、土壤  20世纪80年代以前.治理石油烃污染土壤还仅限于物理和化学方法,即热处理和化学浸出法。热处理法是通过焚烧或煅烧,可净化土壤中大部分有机污染物。但同时亦破坏土壤结构和组分,且价格昂贵而很难实施。化学浸出和水洗也可以获得较好的除油效果。但所用的化学试剂的二次污染问题限制了其应用。早在20世纪70年代。为了解决输油管线和储油罐发生故障漏油和溢油时土壤被石油污染的问题,美国埃索研究和工程公司就已经开始寻找清洁的生物解决方法,并且其实验室研究找到一种有效的“细菌播种法,开了生物修复石油污染土壤先河。上世纪80年代以来,污染土壤的生物修复技术越来越引起人们的关注.生物修复技术也取得了很大进步,正在逐渐成熟。  2、水体  水体石油污染和土壤治理不同,水具有流动性,不及时处理会使污染范围以很快的速度不断扩大。因此.水体石油污染首先是控制污染然后再对污染水进行处理。而对收集上来的污水以及石油工厂排出来的石油污水采用生物处理法。生物处理法也称生化处理法。生物处理法是处理废水中应用最久、最广和相当有效的一种方法。它是利用自然界存在的各种微生物,将废水中有机物进行降解,达到废水净化的目的。  3、空气  然而,对当今的空气状态,大家有目共瞩,石油工业对空气的污染,危害已经相当明显。到目前为止,对于石油产品对空气污染还没有一种很好的治理方法,局限于采用控制油气排放等措施,如制定汽车尾气排放标准等.而具体的污染治理方法还有待于人类进行探讨和研究。石油对空气的污染仅限于其所含的具有挥发性的物质以及轻质石油产品了,而不像对于土壤和水体,石油中的粘稠胶体可以在这两者中成片成块的形成时间很长的污染。虽然如此,石油产品对空气的污染是非常严重的,对空气相对于水体更具有流动和扩散性,治理更加困难。
