What are the serious consequences of water pollution on the ecological environment?

1. The drinking water safety of urban and rural residents is seriously threatened.

Due to the serious water pollution in China, the drinking water safety of urban and rural residents is threatened. According to the survey of the health department, 65.4% of the population in China drink substandard water. 65438-0989, the State Environmental Protection Bureau organized a survey on the protection of drinking water sources in key cities of national environmental protection. The results show that 48% of surface water sources and 20% of underground water sources are not up to standard. The social problems caused by water pollution are quite prominent. The typical cases are 1994 and 1995, which caused millions of people in Huainan, Bengbu, Xuyi and other cities and counties to have no water for a period of time, and the local people reacted strongly. In recent years, the frequent occurrence of cyanobacteria in Taihu Lake has made it difficult for Wuxi waterworks to get water, and some waterworks have stopped production. Many areas in the Haihe River Basin have become "sewage counties" and "sewage towns", making it difficult for local people to drink water.

2. It has a serious impact on industrial and agricultural production.

China is a country with relatively poor water resources, and its per capita water resources are equivalent to a quarter of the world's per capita, ranking 88th in the world. With the development of industry and agriculture and the improvement of people's living standards, the contradiction of water shortage is becoming increasingly tense. At present, the increasingly serious water pollution has further aggravated the contradiction of water shortage. Liaohe River Basin, Haihe River Basin, Huaihe River Basin and other vast areas are originally the areas with the most serious water shortage in China. Serious water pollution has aggravated the contradiction of local water shortage and caused serious losses to industrial and agricultural production. In addition, due to the shortage of water resources, seven cities and regions have been using sewage irrigation for many years, and the sewage irrigation area in Haihe River Basin alone has reached 6.5438+million mu. Long-term sewage irrigation has polluted the soil in sewage irrigation area, making crops have some residual poison, and some of them are even inedible. Water pollution has also had a serious impact on fisheries. In some heavily polluted river sections, fish and shrimp have disappeared.

It poses a serious threat to people's health.

In areas with serious water pollution, on the one hand, the safety of drinking water is threatened, on the other hand, long-term sewage irrigation has caused the pollution of surface water, groundwater, soil filling, agricultural and livestock products and the destruction of agricultural ecological environment, which poses a threat to human health. According to the health survey results of residents in some areas, the incidence of intestinal diseases, cancer and congenital malformation of infants in polluted areas is significantly higher than that in control areas.

4. Cross-administrative water pollution disputes are becoming more and more acute.

Serious water pollution has led to frequent water pollution accidents in some areas, which has led to many pollution disputes, especially cross-administrative water pollution disputes. Take the water pollution disputes at provincial boundaries as examples, such as the pollution disputes between Dezhou in Shandong and Wuqiao in Hebei, Qingyuan in Zhejiang and Songxi in Fujian, Wujiang in Jiangsu and Jiaxing in Zhejiang, which directly affect the local social stability.
