80% of human diseases related to water

Increasing incidence of various types of abnormal root causes. Toxic organic compounds in the environment and lead, mercury, cadmium, chromium, copper, nickel and other heavy metals, through the respiratory, digestive, skin and other ways to be absorbed by people or animals. Some mucus in vivo into a complex organic molecules attached to the body wall and hinder the exchange of oxygen and carbon dioxide, inhibit cell growth and development, destruction of cell contents, reduced enzyme activity, causing acute and chronic poisoning, resulting in cell distortion, or lead to cancer and even death. Some heavy metals, when the water content reached ppb (concentration units to 10 units for a 9 th) order of magnitude, the metabolism will act as a catalyst to the liver, lungs, heart and other lesions occur. Therefore, the distortion of the body of toxic substances, cancer of the direct culprit. Especially those refractory toxic substances in their migration pathway continue to accumulate in the body, so that gradually increased the chance of human disease,[link widoczny dla zalogowanych], the incidence will inevitably increase. Thus, although the incidence of food hygiene practices and genetic and other relevant, but the most fundamental factor is the result of environmental pollution. Of esophageal cancer in Henan Linzhou deaths every year around 150/10 million, also found that chickens in the region has a high esophageal cancer mortality (175/10 million); Qidong County, Jiangsu Province, a high incidence of liver cancer, The local duck's liver cancer incidence rate was also high. Such Therefore we can say the most important factor restricting health is the environment, especially the water environment. Despite the prevalence of water pollution in the world, but China's water pollution situation worse. Especially in the last three decades, as China's rapid economic development, the traditional economic model so that our limited resources continue to decline gradually increased waste water environment is deteriorating day by day. The 745 nationwide state-controlled sections of surface water, the majority of Class III standard reach, the river flows through the city more than 90% of serious pollution, the majority of lakes eutrophication, the proliferation of algae, the green gruel water contaminants, an unpleasant odor, it is unsightly, is known locally as At present, China's water environment, the major pollutants far exceed environmental capacity, the situation is grim. The proliferation of cyanobacteria in the national spread rapidly from south to north, has spread to Beijing and Tianjin areas. National urban centralized drinking water sources have different degrees of overweight, nearly three hundred million rural people I2 Frequent red tide offshore area is increasing, most have been exceeded. Green fresh water, sea water in the red, China's rivers and lakes have been sent a dangerous signal of mankind. Even more frightening is groundwater pollution. Because of its surface water pollution than air pollution and is difficult to come into view, more likely to be ignored, shelved, to be avoided, or even simply as waste reduction. At present in China plains, not to find out a lot of contaminated groundwater, competition has become a very easy thing. If in the region of over a hundred types of organic pollutants in groundwater species. Groundwater pollution in Beijing is even more prominent, and even municipal water pipes, secondary pollution phenomena occur. Masses of water pollution on the health of the capital has become a greater threat. According to 2003 If there's high cancer Huaihe River Village - Sun County village of Henan Shen Qiu, Zhou Yingxiang, a large number of villagers died of cancer; Beichen District Sai Village, Liu quick Village, cancer patients up to 120 people; Some petrochemical industrial area around the cancer rate by ten times; Hebei, Shandong, some coastal villages exceeded the incidence of cancer than half. Beijing under some leakage of contaminated landfill sites has resulted in more than ten square kilometer area around the water undrinkable, even in the upper hand in Sheung Shui, Beijing Xiaotangshan area, but also actually had a high incidence of the village. Algae outbreak in the vicinity of rivers and lakes, as some species of toxic algae, it is caused by the algae toxicity to humans and animals have occurred. Strange disease, plague outbreaks, although the incident, but with the long-term environmental pollution are closely related. Again and again to the nature of human sewage casually give retaliation. Most worrisome is that China's severe water pollution situation is still in development. If our environment out of balance, loss of control, severe pollution incidents may occur at any time. SARS emerged yesterday, today and bird flu, it will appear tomorrow variation faster and more difficult to control the odd disaster abnormal? The occasion: a critical juncture, the management of any acts of omission, is on people dereliction of duty and criminal acts of future generations. Looking population Newsweek in November 2005 21Et
