Is there any health effect on drinking deep groundwater for a long time?

The impact of groundwater on people's health has been a major issue in China before. What are the dangers of unhealthy water sources due to groundwater pollution?

1Dental fluorosis is caused by excessive intake of fluoride contained in drinking water, etc., resulting in brown spots and staining on the teeth.

2. Skeletal fluorosis: Bone abnormalities such as arthritis and osteoporosis caused by excessive intake of fluoride contained in drinking water.

The 3 major osteoarthritis is one of the endemic diseases caused by food and drinking water, and the abnormal development of the bone and diaphysis ends becomes degenerative arthropathy.

4. Gram Mountain Disease is a disease dominated by cardiomyopathy. It was named because of its high incidence in Keshan County, Heilongjiang Province, China. The soil and water in the region are low in selenium, and the disease is thought to be caused by malnutrition, which is predominantly due to selenium deficiency due to self-sufficiency.

Ground water is water that exists in cracks in rocks or soil voids in the earth's crust. Water that is widely buried below the surface of the earth in various states is collectively referred to as groundwater. Atmospheric precipitation is the main source of groundwater.

According to the different underground burial conditions, groundwater can be divided into three categories: upper stagnant water, diving water and artesian water.

According to the burial conditions, groundwater can be divided into aerated water, diving water and confined water.

As one of the states of existence in the natural water cycle, groundwater has many conveniences for our modern life, such as well water and spring water. Therefore, it cannot be called "groundwater hazards". I don't know if you're asking about the dangers of over-exploitation of groundwater.

To summarize the following points:

1) The groundwater level has dropped sharply and rapidly. Formation of groundwater landing funnels.

According to China Environment News, in 2005 there were 188 groundwater landing funnels across the country. Of the 171 groundwater landing funnels for which systematic statistics are available, 65 have expanded (6,736 square kilometres), 57 have shrunk (2,175 sq kilometres), and 49 have remained stable.

2) Cause ground subsidence and subsidence.

For example, around 05 years, the Yangtze River Delta region in Jiangsu Province, Jiangsu, Xi, Chang, and Zhejiang's Hangzhou, Jia, Hu and other regions formed three regional subsidence centers, and the maximum cumulative subsidence reached meters. Shanghai is the city with the earliest subsidence and the greatest influence.

3) The water volume of rivers and lakes decreases, resulting in disasters such as broken flow and drying up.

For example, due to the overexploitation of groundwater in the Dunhuang area, the flow of the Dang River and the Shule River has been cut off, and the Dunhuang River is likely to become the next Loulan. Point 4 can also be used as an example.

4) Reduce the flow of springs. The decrease in the flow of the spring has destroyed the protection of ancient buildings and cultural relics, and even the ancient wells and tourist attractions have lost their due tourism value due to the depletion of spring water.

5) Wells are depleted. The reduction of water consumption in a single well causes the water well to be scrapped, or the pump is dropped, and the sediment content increases, which increases the equipment maintenance cost and power consumption.

6) Affect the growth of vegetation and exacerbate desertification. Grazing is mainly seen in the Northwest Territories.

7) Affect soil and water conservation, resulting in soil erosion. It is mainly found in central Shaanxi and the edge of the grassland.

8) Destroying houses, highways, railways, bridges, water conservancy, municipal utilities, mines and other engineering buildings cracking, tilting, collapsing, and buriing. This is similar to the implicit effect of isopoint.

9) Deterioration of groundwater quality.

The increase in the hardness of groundwater has certain harm to human health, which can make the gastrointestinal and digestive system uncomfortable, and may cause cardiovascular diseases and kidney stones in the human body. It is understood that in recent years, the incidence of cardiovascular diseases and kidney stones in cities has increased compared with the past, and the salt pollution of drinking water is also a cause that cannot be ignored. Many scholars believe that the human body needs to consume 2 3 grams of salt a day, and this need can be satisfied even if you do not eat salt-added food, but some people consume as much as 30 grams of salt a day.

On average, one in five people who eat a lot of salt will develop high blood pressure. Some scholars believe that people without high blood pressure, such as excessive intake of salt, are prone to blood clotting and closing, causing cerebral thrombosis and myocardial infarction.
