1. 海洋核污染检测

海洋可以稀释核辐射。

海洋对核辐射水没有净化能力,只能随着洋流稀释。净化是指将其中的污染物以过滤、转化或分解的方式去除掉。但核辐射是无法去除掉的,只能让放射性元素自己衰变为稳定的非放射性元素,所以无法净化。其实没有必要把放射性完全去除掉,只要放射性强度在安全限度以下就可以了,海水依靠稀释就能做到。因为严格地说,放射性广泛存在于自然界,无处躲避,也没有必要躲避。只要其强度在安全值以下,对健康就没有影响。

2. 海产品核污染检测

不能

核污染对鱼类的影响主要是通过基因突变引起的。恶性突变会随着鱼类的繁殖一代代传下去,而人类又非常喜欢吃海鲜,尤其是来自海洋的野生海鲜,那么这种由核辐射导致的变异基因就会进入人体内,间接来影响人体的DNA,有可能也会让人类的基因发生一些不好的变异。

3. 海里核试验污染

地下核试验会产生放射性核素,人们非常关注它造成的环境危害。

这种危害很大程度上依赖于物理和化学机理,这些机理控制着放射性核素如何进入地下水并将它传播给生物圈内的各种物种。

在内华达州南部和美国其它的试验基地,相关的环境包括地下水中潜在的污染、它们对环境或农业所产生的影响,以及它们对那些可能会发生间接生态影响的地方的地表水源的极限排泄的环境。

在南太平洋的阿留申群岛的海洋试验区,人们还对地下水中渗漏的放射性核素进入海水以及由此引起的对渔民和其它生物所产生的影响表示关注。

地下核试验也会污染土地.

4. 海底核试验污染

被核辐射的海水含有钴、氚等有害元素,这些元素对海洋生物、动物的生存环境会有直接的严重的影响。由于海水是流动的,洋流将被辐射的海水带到海洋各地,所到之处相关联区域人类的身体健康将受到极大的的影响,故将被幅射的海水倒入大海,违反国际有关法律法规的规定,也会引起全世界、全人类极大的关注。

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

6. 海洋核污染处理

应该会被海水稀释,因为海水中存在大量的硼酸,可以中和一些核辐射物,还含有很多稀有金属具有抗核原素的功能,就如同一滴钢笔水在盆里会被盆水稀释,但源头要控制住,不然海里的鱼吃了会对鱼的健康有危害,也可能会导致鱼的基因变异成异型生物,也未可知。

7. 海洋核污染检测技术及对海洋影响

海洋核污染对城市的影响为海里打上来的鱼虾不能食用。海水不能养殖。海水不能淡化饮用。

8. 海洋生物核污染

海参是海产品,他当然受到黑辐射的影响还不是影响,包括海里面的任何海产品和水产品包括各种鱼类以及海参,海带等水产品都要受到核辐射的影响因此,只要是海里面的产品,海水受到辐射影响了,他都受影响我们强烈反对任何国家向海洋群岛海废料维护世界人民的身体健康
