上海水質污染

㈠ 黃浦江水污染的原因

原因分析:
水質變化主要受區域內的工業污染源、農業污染源和生活污染源等影響。另外，黃浦江水系承接約80%的太湖泄水量，上游來水水質對黃浦江水系水質變化也有至關重要的影響。
1) 工業及生活污染源
近20年來，上海市的廢水總量基本穩定，但其構成發生了顯著變化，工業廢水量不斷下降，而生活污水量不斷上升.
1.1工業廢水
工業廢水是水體有機物污染和重金屬污染的主要來源［6］。1991—1996年，工業廢水量大於生活污水量，呈緩慢下降趨勢，年均下降3.0%；1996—2005年，工業廢水量小於生活污水量，呈快速下降趨勢，年均下降8.5%，與水質污染指數之間呈極顯著的正相關關系（r=0.892，P≤0.01），即工業廢水量的快速下降是該時期內水質改善的主要影響因素。2005—2010年，工業廢水量占總廢水量的比例開始小於25%，呈緩慢下降趨勢
1996—2005年，工業廢水達標排放率明顯上升，未達標排放量逐年下降，成為水質改善的主要影響因素；2005—2010年，達標排放率和未達標排放量基本穩定。
隨著工業廢水量的下降及廢水處理能力的加強，工業對水體的污染貢獻不斷減小，黃浦江水系的有機物和重金屬等污染得到有效控制。
1.2生活污水
1991—1996年，上海市生活污水量從6.33億t激增至11.44億t，年增長率達到12.6%，為
該階段內水質惡化的原因之一（r=0.506，P＞0.05）；1996—2003年，生活污水量基本穩定，為該時期水質改善創造了必要的條件；2003—2010年，生活污水量再次快速上升，從12.11億t上升至21.15億t，加大了水質改善的難度。
生活污水中氮、磷等物質濃度較高，上海市的生活污水中，氨氮平均質量濃度可達30～50mg/L，總磷質量濃度可達3～5mg/L。雖然生活污水處理率逐年提高，但相對於工業廢水，上海市生活污水處理率相對偏低，生活污水量的增加使黃浦江水系的營養鹽物質污染有加重趨勢。

2農業污染源
農業污染主要由農田化肥流失和畜禽養殖產生的糞便造成，可分別用化肥施用量和畜牧業產值來表徵。畜牧業污染以高氮磷為特徵，主要的污染載體為畜禽糞尿，為上海市首要的農業污染來源。1986—1996年，上海市畜牧業產值呈逐年增長趨勢，與水質污染指數變化之間呈極顯著的正相關關系（r=0.792，P≤0.01），即畜牧業污是造成該階段內水質惡化的主要因素；1996年後畜牧業產值基本穩定，並在2003年後出現一定的下降趨勢，為水質改善創造了必要的條件。
近20年來，化肥施用量呈緩慢下降趨勢，年均下降4.0%，與水質污染指數變化趨勢無明顯相關性，化肥施用量並非影響黃浦江水系水質的主要因素。

3上游來水
近年來，上游來水總體水質變化可分為3個階段。第一階段（2002年前），上游來水總體水質基本穩定，各條來水水質均優於楊浦大橋斷面；第二階段（2002—2004年），各條來水水質均急速惡化，攔路港、太浦河、大蒸港和胥浦塘來水的水質污染指數分別上升62.1%、62.6%、40.4%和40.3%，楊浦大橋斷面與各條來水之間綜合水質差異明顯縮小，部分來水水質（胥浦塘來水）已劣於楊浦大橋斷面；第三階段（2004—2010年），水質呈緩慢改善趨勢。

㈡ 現在上海水質怎麼樣

市場還是有的，上海喝的全是黃浦江過濾的水很臟的，只要肯下功夫開拓，市場還是很大的

㈢ 上海的水質最近怎麼了、

可能是管子裡面的塗層味，也可能是氯氣（或氯化物）味。 建議等水開後，將壺蓋打開，再燒一分多鍾，就沒異味了。

麻煩採納，謝謝!

㈣ 上海水資源污染情況

上海的水資源短缺，主要源於以下幾個原因：一，上海人口眾多，所以人均水資源量很小。上海水資源總量雖然有26.9億立方米,但上海的人均水資源量只有201.2立方米；二、絕對用水量大。由於工商業發達，工業、商業、生活用水數量驚人；三、可用水源稀少。流經上海的水源，上游在江浙地區，也是人口密集，加上上海本地，水源被污染情況嚴重。

㈤ 請詳細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.

㈥ 上海的水質怎麼樣

一，優質不可能，但是，沒有問題。
二，若三樓以上，用的是水箱的水，就更會結垢。
三，與水管也有關系……

㈦ 上海水質是否被污染

水質污染來源主要復是工業廢水、農業制面源、生活污水、還有大氣沉降、底泥污染等方面。
上海屬於太湖流域，處於長江下游，現在太湖來水、長江來水都是受到上游一定程度污染的。所以上海本身的水質就不太好。加上上海當地的工農業及生活污染，水質污染現象就更嚴重了。
上海的自來水一直味道比較大，以前主要的水源是來自黃浦江上游，現在直接到長江口的青草沙取水了，水質稍有改善。

㈧ 上海的水質很不好

未必是水的問題,你洗頭還不是用水?何況洗頭用的水一般是燒過水.
我覺得是空氣專質量問題,上海揚塵污染很屬嚴重,隨便出去一會就會發現鼻孔里都是黑的臟東西.
我也是這樣,一天不洗頭要死人的,油性頭發的人一天不洗都油在一起了,自身因素也有一定原因,不過我去外地那些農村,頭發就沒那麼誇張了.

㈨ 上海水質最差的地方

工業區的都好不到哪去，全是工業污水，能不污染嗎

㈩ 上海水質發黃是怎麼回事

發黃？不是吧我住那麼多年怎麼沒事~是不是水箱不幹凈啊~上海水質是沒有外地好啦，不過細菌應該不至於吧~牙齦出血不是上火的問題嗎~你大概剛來上海水土不服
