How do residents ensure the health of drinking water?
Health is the foundation of human beings-while enjoying modern civilization, the overall health of human beings is becoming more and more worrying, and people are still plagued by various diseases. Cancer, cardiovascular and cerebrovascular diseases and diabetes are called the three killers of modern human health. At present, it is on the rise. Gastrointestinal diseases, intractable constipation, osteoporosis, premature senility and various lithiasis can be seen almost everywhere, especially various infectious diseases have brought us great psychological panic. Now the pollution of the whole environment, including the food we eat, the water we drink and the air we breathe, is harmful to human beings. We must realize that human health is facing great challenges, and health can not be ignored! Water is the source of life-water is the first element of human life and the best solvent, which nourishes the human body. Without water, no part of the human body can survive. Healthy and clean water can enhance human immunity and promote cell metabolism. Therefore, some experts warned us that while paying attention to health, we should also pay attention to providing clean water for cells and strive to create a fresh and pure living environment for cells. At the same time, with the development of society and the progress of human beings, the demand for water resources is also increasing. We human beings can't live without water, but the water resources that can be directly used by human beings are decreasing year by year with the passage of time and becoming more and more scarce. Water pollution brings us-as we know, a series of problems such as ecosystem deterioration and biodiversity destruction caused by water crisis seriously threaten human survival. According to the survey of the World Health Organization, there are 222 1 species of organic substances detected in water bodies around the world, and 654,380+0.2 billion people worldwide suffer from various diseases due to drinking polluted water, with a prevalence rate as high as 20%. Diseases caused by drinking water account for 80% of human diseases, and there are 40 water-borne infectious diseases in the world that have not been controlled. Every year, 25 million children in the world get sick and die from drinking polluted water, especially diseases caused by excessive heavy metals and impurities. Such as chlorine nitrate, nitrite, lead, arsenic, mercury and so on. Besides them, there is fluorine that we are very afraid of. Endemic fluorosis, also known as endemic fluorosis, is a chronic systemic disease caused by long-term intake of excessive fluorine, mainly manifested as dental fluorosis and skeletal fluorosis. The disease is widely distributed. Except overseas, almost all provinces, municipalities and autonomous regions in China have epidemic areas of varying degrees, and the estimated number of patients is nearly 4,000. In addition, diseases of digestive system should not be underestimated, such as Escherichia coli can cause gastroenteritis, diarrhea, urinary system infection, cholecystitis, etc. Salmonella can cause typhoid and paratyphoid; Hemolytic jaundice caused by hemolytic streptococcus. In a word, it is global water pollution that causes many diseases. Water pollution has become the first killer of human health. The new concept of modern drinking water-the increasingly serious water pollution in the world and the pollution of water resources in China, has attracted great attention of our government. Out of concern for the people, the party and the government put the interests of the people in the first place and frequently promulgated relevant laws and regulations. First, in order to avoid the secondary pollution of water tanks in residential buildings, the state stipulates that water tanks should not be set in the design of high-rise buildings. Secondly, in order to ensure the delivery of qualified domestic water for thousands of households, the Ministry of Construction clearly stipulates that cast iron pipes and galvanized pipes shall not be used in drinking water pipelines; Third, on April 2, 2004, Beijing Evening News reported that in order to improve the urban water supply safety guarantee rate and ensure the high-quality water supply during the 2008 Olympic Games, Beijing Water Supply Group will invest 200 million yuan this year for the technical transformation of water plant facilities and water supply network. It is indeed encouraging that the country has made such great efforts to change the water supply conditions, but it needs to be done step by step, and it is impossible to solve thousands of households at the same time. For example, the water tank and the old pipe water supply system in the building are still in use. The problem of drinking water purification needs to be solved urgently, not immediately. What should I do? People should choose various ways to change drinking water conditions and improve our quality of life under certain conditions. Li Yadong, a water expert and associate researcher at the Institute of Environmental and Health-related Product Safety of China Center for Disease Control and Prevention, said: "With the development of industry, due to various processing, exploitation of various mineral resources, fuel, coal, pesticides and fertilizers, our water pollution is becoming more and more diversified. In 1970s, a strong carcinogen MX was found in the water of Finland. Finally, the United States Environmental Protection Agency found dozens of suspected carcinogens in water. Due to water pollution, more and more diseases may occur in human body. We should pay enough attention to this problem. We now advocate installing a water purifier at home, which can better turn off the water before it enters our body. The function of water purifier is to basically remove organic matter from water, and some types of water purifiers can also remove inorganic pollutants. Installing such a device at home will avoid the pollution of domestic drinking water caused by various factors such as secondary water supply and pipeline pollution, and play a positive role in our health. " With the continuous progress of human society, the way of drinking water has also changed. The new concept of drinking pure water and supplying tap water in different quality has become the goal that all countries in the world are striving to achieve. Some countries in Europe and America, as well as Japan, South Korea and Hong Kong. Since the 1980s, its pure water penetration rate has reached over 90%. Relevant departments of China government also proposed to gradually introduce purified water into families before 2008.
