You have to know how water pollution causes cancer.

Time:2018-12-01 Views:2505
In China, 90% of cancer is caused by water pollution!!!!

Due to the lack of authoritative data, the number of "cancer villages" spread on the Internet is not uniform, but most reports point the high incidence of cancer and other diseases at the pollution of drinking water. According to users of Sina Weibo, who signed "Xu Chao-Environmental Researcher", 64 of the dozens of "cancer villages" in China are caused by water pollution, ranking first.

At present, there are 2 million new cancer patients and 1.4 million cancer-related deaths in China. Some people in the industry provide data to prove that there are 243 cancer villages in China. In many areas, the incidence of cancer is higher than that of cardiovascular and cerebrovascular diseases, which has become the first cause of death.

One of the reasons why there are so many cancer villages is that the lakes, reservoirs, rivers and underground rivers in the corresponding areas are seriously polluted. In 2011, the inspection proved that 55% of the urban water quality in China was not up to standard or even seriously unqualified. Zheng Chunmiao, director of the Water Resources Research Center of Peking University, said that about 360 million people in rural areas of China could not drink up to the standard drinking water.

The existence of cancer villages makes us pay more attention to the safety of drinking water, and tap water is the most important relationship with drinking water. As we all know, the main source of tap water is surface water such as local reservoirs and rivers, and some areas are from deep wells. Water companies can be said to treat water sources more strictly, but due to technical reasons, there are still some harmful substances such as heavy metals, residual chlorine, bacteria can not be removed, which has laid a hidden danger for the health of residents.




Behind Cancer Village/Area: Drinking Water Pollution

In some areas of China, the ground water and groundwater have been seriously polluted, and they have come to the edge of the cliff that kills people! uuuuuuuuu Practice has proved that drinking water quality is closely related to cancer. When drinking water is contaminated by toxic, harmful chemicals or pathogenic microorganisms, it can cause abnormal sensory properties of water and cause diseases, while long-term intake can cause canceration. Many areas in China have been found to be cancer-prone. Many cancer villages, townships, counties and even cancer basins (such as some areas in the middle reaches of the Huaihe River) have emerged. The main culprit is the large-scale pollution of drinking water.

Inorganic arsenic: no trace of carcinogenesis in drinking water

According to experts‘assessment, arsenic hazards in China, especially arsenism in drinking water, will become a major problem of drinking water sanitation in China in the 21st century. The 2007 edition of Food, Nutrition, Physical Activity and Cancer Prevention points out that:

There is abundant evidence that inorganic arsenic in drinking water is one of the causes of lung cancer, and inorganic arsenic contaminated water may be one of the causes of skin cancer. Arsenic and arsenide are considered carcinogens. Limited evidence suggests that inorganic arsenic-contaminated water is one of the causes of renal and bladder cancer.

The sources of arsenic pollution are extensive.

Arsenic compounds are widely used in agriculture as herbicides, insecticides, fungicides, rodenticides and various preservatives. If used in large quantities, they will cause serious pollution of crops and lead to the increase of arsenic content in food. In addition, groundwater near arsenic-bearing and other non-ferrous metal deposits (such as well water and hot springs) contains high arsenic content, which is one of the main sources of drinking water pollution.

Mutagenicity of arsenide

It has been proved that many arsenides are mutagenic and can cause gene mutation, chromosome malformation and inhibit the repair of DNA damage. Sodium arsenate can be teratogenic to mice through placental barrier. Epidemiological investigation shows that inorganic arsenic compounds are related to the occurrence of human lung cancer and skin cancer. The World Health Organization (WHO) confirmed in 1982 that inorganic arsenic is a carcinogen and can induce many kinds of tumors.

Regionality of arsenic poisoning

Arsenic poisoning is also regional in China. There are two types of endemic arsenic poisoning in China: drinking water and coal burning. Drinking water arsenism is caused by excessive arsenic content in drinking water. This type is mainly concentrated in Xinjiang, Inner Mongolia, Shanxi and Taiwan. Coal-burning pollution is caused by burning high arsenic coal, baking grain and pepper with coal fire, which seriously pollutes indoor air and food. This type is mainly found in Guizhou Province at present.

Local arsenic poisoning is mainly caused by skin damage. The main symptoms of endemic arsenism are excessive keratosis of palm rubbings, increased incidence of peripheral neuritis, skin cancer and other symptoms. The patient began to show intermittent claudication, and later developed skin darkening, brown or black-brown spots, highly keratinized palms and toes, which can lead to skin cancer.
