1. 海洋被污染了會怎么樣

具體如下：

1,、垃圾污染

工業(yè)冷卻水和工程殘土,、垃圾及疏浚泥等,。前者入海后能提高局部海區(qū)的水溫，使溶解氧的含量降低 ,，影響生物的新陳代謝，甚至使生物群落發(fā)生改變,；后者可破壞海濱環(huán)境和海洋生物的棲息環(huán)境,。

2、噪聲污染

利用天然聲納進行導航和捕獵,，讓無脊椎動物深受其害,。勘探船產生的聲音污染對頭足類動物以及其他海洋動物的生存造成不利影響,。

3,、過度捕撈

人類的捕魚活動導致海洋中生存的某種魚類種群不足以繁殖并補充種群數(shù)量。現(xiàn)代漁業(yè)捕獲的海洋生物已經超過生態(tài)系統(tǒng)能夠平衡彌補的數(shù)量,，結果使整個海洋系統(tǒng)生態(tài)退化,。

4、冰川融化

由于冰蓋的融化,，奇特的低鹽度海水正在慢慢的消失,，截止到2002年， 96%的低鹽度棲居環(huán)境已經消失殆盡,。大部分以冰川徑流作為供水源的地區(qū)將會發(fā)生嚴重的缺水危機,。

5,、石油泄漏污染

石油污染在海洋表面形成面積廣大的油膜，阻止空氣中的氧氣向海水中溶解,，同時石油的分解也消耗水中的溶解氧,，造成海水缺氧，對海洋生物產生危害,，并禍及海鳥和人類,。

2. 海洋污染到了什么程度

就目前的開采技術而言，基本上無論是哪種方法,，都是促使可燃冰中天然氣與水的分離,，要促使其分離，必然要改變其溫度及壓力環(huán)境,，這樣就可能會產生一系列不可預知的環(huán)境問題,，如溫室效應的加劇、海洋生態(tài)的變化及引起地質災害的可能,。

可燃冰的成分主要是甲烷,，甲烷是一種強溫室氣體，對大氣輻射平衡的影響僅次于CO2,。

目前探明全球可燃冰儲量的甲烷是大氣圈中甲烷的5000倍,，在開采的過程中，即使如此巨大的甲烷總量哪怕是0.5%進入大氣層,，對全球變暖的影響也是難以估量的,，如果開采中稍有不慎，則必然會加劇溫室效應,。在海洋中開采可燃冰帶來的環(huán)境問題更多,，一方面甲烷如果直接進入海水中，則會很快發(fā)生微生物的氧化反應,，從而會改變海水的化學屬性,，如果大量進入，其氧化過程中會消耗海水中大量的氧氣,，使得海洋缺氧,，這樣勢必會加速海洋生物的死亡；

另一方面大量直接進入海洋的甲烷還可能會加速海洋氣化及海嘯,，導致海水加速流動及氣壓卷吸,，會嚴重危害海面船只及作業(yè)平臺的安全，甚至強對流的海水會直入空中,，影響航空及陸地建筑的安全,。

在開采可燃冰的過程中，會分解大量的水,，這些水會稀釋巖層空間,，使得地層結構穩(wěn)定性變差,，容易引發(fā)地質災害。

在海洋環(huán)境中,，無論是減壓分解還是激熱分解,，都會導致海底陸坡區(qū)的穩(wěn)定性下降，嚴重則會發(fā)生海底坍塌,，如毀壞海底輸電或通信電纜和海洋石油鉆井平臺等設施,。

就目前的開采方法來看，無論是哪種方法都不能單獨實施,，必須是幾種方法的結合,，如果使用二氧化碳置換法、化學試劑減壓法與其他方法的結合實施,，則勢必會產生新的問題,，這些化學試劑及二氧化碳注入到地下后，會嚴重污染地下水源,。

3. 海洋被污染的后果

　　來自長江和省內6大水系所攜帶的大量工農業(yè)廢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，基本已無I類海水,，沿海特別是河口海水中無機氮和無機磷嚴重超標,，海水中磷酸鹽合量在沿海省、自治區(qū)和直轄市中排居首位,。

近岸海底沉積物中氮,、磷超標嚴重，成為海水二次污染的潛在危害源,。另外,，個別海域（如杭州灣和舟山海域）船舶排污及碰撞漏油，海上石油開采溢油等加劇了近岸海域的污染,，有機污染和重金屬也對海水水質產生明顯的影響。

　　海洋災害頻繁——每年發(fā)生大小赤潮近20次

　　我省是風暴潮,、赤潮等海洋災害最為嚴重的省份之一,。每年因臺風給我省海洋漁業(yè)造成的直接經濟損失在數(shù)十億元以上。由于海水水質下降和富營養(yǎng)化,，導致赤潮災害發(fā)生的頻率逐年上升,，給我省的海洋經濟帶來巨大的損失，近年來,，每年發(fā)生的大小赤潮災害近20次,，年直接經濟損失達數(shù)億元。

　　圍海造地——許多珍稀瀕危野生生物絕跡,，破壞生態(tài)

　　我省沿海灘涂資源359．04萬畝,，主要分布在錢塘江和杭州灣兩岸,，以及各海灣。由于不合理的圍海造地,，使沿海自然灘涂濕地面積縮減,，不僅破壞了多種鳥類的棲息地，也使重要的經濟魚,、蝦,、蟹和貝類生息、繁衍場所消失,，許多珍稀瀕危野生生物絕跡,，而且大大降低了灘涂濕地調節(jié)氣候、儲水分洪,、抵御風暴潮,、凈化地表徑流及護岸保田等的能力，同時改變了海區(qū)的水動力方向,，加速了航道和港口的淤積,。

　　海洋食物鏈已經遭到嚴重破壞——經濟魚類資源大幅度降低

　　隨著海洋開發(fā)話動的增多，海洋生態(tài)環(huán)境遭受破壞,，使生物多樣性衰減,，某些生物種類已近絕跡，傳統(tǒng)的經濟魚類資源大幅度降低,，再也形不成漁汛,，海洋食物鏈已經遭到嚴重破壞。東海生態(tài)系統(tǒng)中的主要經濟物種嚴重衰竭,，整體結構發(fā)生顯著變異，系統(tǒng)內部自我調節(jié)的能力受到嚴重損害,。

　　請勿將廢水和生活垃圾直接排入海中

　　造成海水如此惡劣的污染源主要有陸上和海上兩大類,。陸上污染源主要是工業(yè)污水、居民的生活廢水以及農田中使用的農藥通過河流流入大海,，沿海企業(yè)和居民直接將污水和廢水排入海中,。海上的污染源主要有船舶上和港口的油污和生活廢水，養(yǎng)殖場,、海洋工程,、海岸工程產生的污染。

為了使我們的海域不再受污染,，省有關部門已經頒布了一系列的政策法規(guī)對海域污染進行了治理,。同時也提醒沿海的居民不要將廢水和生活垃圾直接排入海中，出海的漁民應該把該回收的都要回收，而不要一丟完事,。

4. 海洋被污染后的現(xiàn)象

污水給魚兒帶來的只有死亡，如果人們吃了被污染的海里的魚,，大多數(shù)會生病的就海洋污染而言,，是個大問題呀,！海洋生物物種一旦遭難，生態(tài)就會失去平衡,，也許會就此產生新物種來適應這種惡劣環(huán)境也說不定。但最大的可能就是愈演愈烈,，最終地球將會成為一顆“死亡星球”,。到時我們就慘了,，還是現(xiàn)在好好保護吧,。

5. 海洋被污染了會變成什么顏色

海水蒸發(fā)不會攜帶核污染。

核污染通常指放射性物質的泄漏,，這些物質會在水中沉積或溶解,，但研究顯示，海水在蒸發(fā)過程中會過濾掉有機和無機顆粒物,，以及放射性污染物,，因此在海水蒸發(fā)的過程中，核污染物質不會被攜帶到空氣中,。

核污染和環(huán)境保護是全球的熱點話題,，應該保護環(huán)境,，避免污染,，同時科學研究也應該繼續(xù)進一步發(fā)展，不斷尋找更好的防治污染的方案和技術,，保障人類的環(huán)境和健康,。

6. 海洋被污染了用英語怎么說

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!

海洋污染英語作文二：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!

海洋污染英語作文三：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.

海洋污染英語作文四：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.

海洋污染英語作文五：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.

海洋污染英語作文六：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. 海洋被污染的繪畫

海上燃犀圖，又稱《海燕圖》,，是中國南宋著名畫家趙伯駒所繪（約活動于公元1254年至1292年間）。趙伯駒是南宋時期的一位重要花鳥畫家,，他深受文人雅士的喜愛,，被譽為“吾國之鳥獸工筆之始祖，其技驚天下而無出其右者”。他的畫作以構圖嚴謹,、筆墨細膩,、形神兼?zhèn)涠Q，海上燃犀圖是他的代表作之一,。這幅畫刻畫了海上巨獸燃犀,，和一支在它身旁飛舞的海燕，氣勢恢弘,，極具生命力,，被認為是中國古代畫的巔峰之作。現(xiàn)今,，海上燃犀圖收藏于臺灣故宮博物院,。

8. 海洋污染我們該怎么辦

防止海洋污染的辦法有。促進海洋開發(fā)與環(huán)境保護協(xié)調發(fā)展,，立足于對污染源的治理,；對海洋環(huán)境深入開展科學研究；健全環(huán)境保護法制,，加強監(jiān)測監(jiān)視和管理,；建立海上消除污染的組織，大力宣傳保護海洋知識,；加強國際合作,，共同保護海洋環(huán)境。

10,、不要破壞珊瑚礁，海藻叢等海洋生物生活的地方,，破壞它們可能會破壞海洋生命鏈,。

10. 海洋被污染了魚兒會怎么樣

　　一、石油危害可分為三個方面：　　1,、一是油氣污染大氣環(huán)境,，表現(xiàn)為油氣揮發(fā)物與其它有害氣體被太陽紫外線照射后，發(fā)生理化反應污染,；或燃燒生成化學煙霧,，產生致癌物和溫室效應，破壞臭氧層等,?！　?、二是污染土壤,，這里我們不必多說明,，大家都知道石油污染土壤的地方，寸草不生,?！　?、三是污染地下水,，我們現(xiàn)在生活的水資源被污染,，以至于地方性癌癥村屢屢皆是,，這石油污染地下水的惡果是日日嚴峻?！　《⑹臀廴臼侵甘烷_采,、運輸,、裝卸、加工和使用過程中,，由于泄漏和排放石油引起的污染,，主要發(fā)生在海洋。石油漂浮在海面上,，迅速擴散形成油膜,，可通過擴散、蒸發(fā),、溶解,、乳化、光降解以及生物降解和吸收等進行遷移,、轉化,。油類可沾附在魚鰓上，使魚窒息,，抑制水鳥產卵和孵化,，破壞其羽毛的不透水性，降低水產品質量,。油膜形成可阻礙水體的復氧作用,，影響海洋浮游生物生長，破壞海洋生態(tài)平衡,，此外還可破壞海濱風景,，影響海濱美學價值。石油污染防治,，除控制污染源,，防止意外事故發(fā)生外，可通過圍油欄,、吸收材料,、消油劑等進行處理?！　∪?、防治治理　　1、土壤　　20世紀80年代以前．治理石油烴污染土壤還僅限于物理和化學方法,，即熱處理和化學浸出法,。熱處理法是通過焚燒或煅燒,，可凈化土壤中大部分有機污染物。但同時亦破壞土壤結構和組分,，且價格昂貴而很難實施,。化學浸出和水洗也可以獲得較好的除油效果,。但所用的化學試劑的二次污染問題限制了其應用,。早在20世紀70年代。為了解決輸油管線和儲油罐發(fā)生故障漏油和溢油時土壤被石油污染的問題,，美國埃索研究和工程公司就已經開始尋找清潔的生物解決方法,，并且其實驗室研究找到一種有效的“細菌播種法，開了生物修復石油污染土壤先河,。上世紀80年代以來,，污染土壤的生物修復技術越來越引起人們的關注．生物修復技術也取得了很大進步，正在逐漸成熟,?！　?、水體　　水體石油污染和土壤治理不同,，水具有流動性,，不及時處理會使污染范圍以很快的速度不斷擴大。因此．水體石油污染首先是控制污染然后再對污染水進行處理,。而對收集上來的污水以及石油工廠排出來的石油污水采用生物處理法,。生物處理法也稱生化處理法。生物處理法是處理廢水中應用最久,、最廣和相當有效的一種方法,。它是利用自然界存在的各種微生物，將廢水中有機物進行降解,，達到廢水凈化的目的,。　　3,、空氣　　然而,，對當今的空氣狀態(tài)，大家有目共矚,，石油工業(yè)對空氣的污染,，危害已經相當明顯。到目前為止,，對于石油產品對空氣污染還沒有一種很好的治理方法,，局限于采用控制油氣排放等措施，如制定汽車尾氣排放標準等．而具體的污染治理方法還有待于人類進行探討和研究,。石油對空氣的污染僅限于其所含的具有揮發(fā)性的物質以及輕質石油產品了,，而不像對于土壤和水體,，石油中的粘稠膠體可以在這兩者中成片成塊的形成時間很長的污染。雖然如此,，石油產品對空氣的污染是非常嚴重的,，對空氣相對于水體更具有流動和擴散性，治理更加困難,。
