① 上海市环境保护采取的措施

市环保局局长徐祖信在接受记者采访时表示,本市第二轮环保三年行动进版展顺利,上海城市权空气质量的改善是连续两轮三年环保行动计划效益的体现,主要得益于全市的产业结构调整、大气环境治理、煤烟型污染控制、扬尘污染控制和提高机动车排放I标准等一系列措施,特别值得一提的是宝山吴淞工业区的整治,拔掉了30个大污染源;城市扬尘治理,首次将建筑工地、工程开挖、马路冲洗等作为考核指标,较有效地控制了城市大气的污染。

② 上海区域空气污染几层楆

根据上海市环境保护局 上海市环境监测中心,最近发布是数据主要污染源为PM2.5和 O3,下面分析下这两种污染。所以上海区域空气污染不管几楼基本上是一样的。

O3也就是人们常说的臭氧污染,实质是由汽车、工厂等污染源排入大气的氮氧化物和碳氢化合物等一次污染物,在太阳紫外线的照射下发生光化学反应,生成臭氧、过氧乙酰硝酸酯(PAN)等二次污染物,参与光化学反应过程的一次污染物和新形成的二次污染物的混合物共同导致大气出现一种具有刺激性的蓝色或棕色烟雾,这种气溶胶颗粒大小一般多在0.3~1.0μm范围内。这样大小的颗粒不易因重力作用而沉降,能较长时间悬浮于空气中,长距离迁移。它们又能散射太阳光,从而明显地降低了大气的能见度。并妨害汽车与飞机等交通工具的安全运行,导致交通事故增多。

而PM2.5,这个大家都清楚是指直径小于等于 2.5微米的颗粒物,这种颗粒物在大气稳定的情况下,可以从地面到500米高度稳定悬浮数日甚至数周,在有风和下雨的情况下才会好转。
这两种污染平时会根据不同的温度、气压等扩撒,所以说不管几楼基本上是一样的。

③ 上海的雾霾来自哪儿啊只报个数据,说下来源,从根本上治啊。

整个长三角这几天都是在雾霾之中,上海不可能独善其身,还有这污染源主要是因为随北方冷空气南下造成的,所以只靠上海是不可能从根本上治理的。就算是上海污染的源头汽车尾气,你也无法治理,一些人现在戴着口罩开着车,这是悲哀

④ 上海市空气污染概况

到俺空间来看看,可以概括下..
上海污染严重,关于这样的文章应该好多的哦!
概括下,自己了解下,调查下,自己原创撒!
这不是一举两得~

⑤ 上海空气污染严重吗

长时间通风(时间六个月以上)分析:适用于异味较轻、通风条件好,可长时间通风放置的装修后居室。广辣衡珠勺对于污染程度较重、通风条件不好的居室则难以达到去除异味的效果。 成本:几乎为零。效果:装修污染治理效果10%~30%2传统方法用空气芳香剂类、袋装芳香类植物、茶叶、菠萝等对抗异味。分析:空气芳香剂类和袋装芳香类植物基本上是起遮盖作用或者根本是一种心理作用,并不能起到从根本上消除污染的作用。

⑥ 请详细描述上海主要污染源

sea temperatures will kill the coral reefs
Ecological conservation group World Wide Fund for Nature said in a report, if we do not take effective measures to biodiversity of coral reefs in Southeast Asia will disappear this century, destroying the coastal economy. World Ocean Conference in Sulawesi's horse was held over. This report just in meeting baked. It was noted that nothing would be a laissez-faire steady increase in water temperature, and kill the coral reefs.
The impact on marine ecosystems
There are many facts indicate that the marine ecosystems in Europe by rising temperatures and sea water temperature effects, in the past, some of the organic organization in the course of their seasonal cycle appears to be earlier than the general situation.
For example, there is a full larvae in the North Sea, is located at the bottom of the marine food chain organisms, the researchers found that the larvae of the busy period before 1958, earlier than 4-6 weeks, which may directly affect this larvae-eating the survival of fish and birds.
Seasonal cycle time change would affect the ecology of the system of biological interactions, and even affect the structure of the marine food chain, including:
Affect the output of North Sea cod;
Rection in the number of seabirds;
An increase in temperature will expand marine fish and plankton in the north extension of the rate of expansion depends on the diversity of marine life, usually 30-100 km per year.
Marine organisms to environmental changes could lead to bio-genetic aspects of adaptability, but the current rate of climate change will hinder such adaptation, because genetic changes need a lot of generations of breeding can be achieved.

Ocean cradle "algae farm" to rece the size of one of two into the causes of the rise in sea temperature?
Around the coast of Japan, called the sea of forest, "algae farm" area, with an average rection of more than 90 years into two. The result is a marine Foundation Institute for Environmental Studies commissioned by the Fisheries Agency has done a survey derived. The source pointed out, recing algae field of marine biodiversity loss is directly linked to, but also with salamander snail, abalone, fish and other fishery resources.

Algae field is widely distributed along the lush growth of algae and seagrass areas. Is a variety of seafood hotbed of biotechnology has played a spawning, fertility "cradle" functions.

The survey combined the state and the autonomous bodies, etc. from 2000 to 20008 was published against the algae area has the latest survey results, and the same year the Environment Agency on the implementation of the 1989-1991 annual survey data obtained were compared.

The results showed that data sets of Hokkaido to Okinawa to about 83.8 thousand hectares of the algae farm, the equivalent of 2 into an area of approximately 18.5 thousand hectares of algae farm disappeared. Is even worse is that the Pacific coast of Shizuoka Prefecture, west of Kyushu in the West Bank area to play, the algae area has reced by nearly 4 into.

A rection in algae area has many causes, the causes are concerned that rising sea temperatures tendency to eat sea urchins and other biological damage caused by algae withered and so on.

Summarizes the findings of the Central Institute of Marine Biology Prize for the Environment Research Institute (Chiba Prefecture) in Thailand starring in this autumn researcher, said: "algae farms and tidal flats with the support of Japan's rich marine life. Algal area has reced the number 2 as I am afraid living there would cause great variety of biological effects. ".

Prevalence rate of increase in global marine bio
It is reported that Cornell University researchers in the 20th century, 70 years since the nine categories the number of marine organisms and disease state of development were compared. They found that: sea turtles, corals, marine mammals and sea urchins and oysters and other mollusks, the incidence rate continues to rise, sharks, shrimp and sea relatively stable incidence of Plastic Packaging Materials, fish, the incidence rate decreased slightly.

Research shows that whales and seals have been a new virus infections, fungal infections e to a large area of coral death, and the carrying viruses and parasites sardines are on the oysters, scallops and clams pose a threat.

The researchers said the resulting increase in incidence of marine organisms for many reasons, the most likely reason is that global warming caused by rising sea surface temperatures. For example, sea-level rise in temperature caused by coral bleaching, to make it easier to be infected. At the same time, global warming has also led to mollusk parasites migrate northward, threatening the northern sea creatures.

Another major reason may be the human overfishing destroyed the marine ecosystem stability. For example, after the death of the Caribbean sea urchins, sea urchins, algae on the survival of food submerged coral, the coral infection.

⑦ 上海空气污染哪里来

上海自身
1 工厂,上海有石化 钢铁 汽车等,都是重污染
2 汽车尾气,轮船尾气,飞机尾气,让整个上海笼罩在尾气中
3 建筑,餐饮等

⑧ 上海市空气中主要污染物为

排放到空气中的有害物质,大致可分为【天然污染物】和【人为污染物】两大类,从世界范围看,排放到空气中的气体污染物较多为【颗粒物、二氧化硫、二氧化氮】等
望采纳。

⑨ 上海的空气污染严重吗

LS哪位的数据我觉得非常可以说明上海的天气。其实上海的空气质量还是相当不错的,只是因为汽车尾气和工地扬尘比较多一点所以会造成一定的污染,但总体控制的还是不错的,比起很多城市比如说北京这类的要好得多了,只要是晴天,基本上都是蓝天,而不像有些城市那样总是灰蒙蒙的。而在夏季吹海风的时候上海的空气是最好的,蓝天白云,会看得人非常舒服。

当然,我觉得上海的空气质量和青岛、厦门比还是有一点差距的

⑩ 上海这几天空气质量真的很差!但是污染源主要是什么真的只是汽车尾气吗

虽然说汽车尾气,工业废气排放等多方面原因造成空气污染,但是这几天这几天空气污染严重是因为气候的原因,自从上一次冷空气将北方的污染源吹到上海后上海的空气质量一直没有好转
