There is knowledge to boil the water: It may not be safe either that boiling is drunk
If continuation is boiled for some time after boiling the running water, chlorine in the running water will be turned into a compound which call three steamed methane, have liver toxicity, kidney toxicity and carcinogenic Drink the water health and environmental protection that oneself boils, this view has already been accepted by the increasingly many person. However, boiling the water has certain knowledge. Contain chlorine in the running water, water has not reached the boiling point, chlorine will not volatilize to the air, do not endanger the human body. Boil running water, continue, boil period, chlorine in the running water will take place chemical change, turn into a compound which calls three steamed methane, have liver toxicity, kidney toxicity and carcinogenic. Three steamed methane will be evaporated in a large amount as the temperature rise, while boiling the water, boiling the soup, boiling the porridge at home, must turn on kitchen ventilator and keep kitchen ventilate, water can be shut in the fire in two minutes boil. Especially, after the heavy rain, chlorine in the running water is known, so should pay attention to ventilating the question even more while heating up water. The running water boiling steam includes a lot of poisonous housewives carcinogenically, while boiling the boiled water, used to, make many a odd minutes such as boiling such as water, let chlorine of water disappear by this, but the doctor reminds this movement, will increase and suffer from the cancer risk instead. Because of chlorine in water, turn into three steamed methane after heating, store in the vapor, sucking excessively will suffer from bladder cancer, the pregnant woman will also miscarry. Finish boiling the boiled water, you will open the cover at once, will let it be cold? Or make many a odd minutes such as boiling such as it, let chlorine in water disappear, the doctor tells you two movements, will all let you increase and suffer from the cancer risk, this is because of our running water, the chlorination is come to sterilize, but chlorine will be turned into three steamed methane when heating, there is a carcinogenic risk. Once there was a building constructor executive, went to the heated swimming pool to swim everyday, passed away in cancer after one year, the doctor suspects that sucks too many three steamed methane. How does that avoid sucking three steamed methane? The doctor talks about the heated swimming pool, should pay attention to ventilating, had better have chlorine density that is measured too, have hot bath, wash a long time, water temperature don't too high, boil boiled water, you had better open machine of soot arranged, or open the cover after the boiled water is cooled. Live a closely bound up life to may not drink security and common people of safety drinking water in boiling of running water. At present, led by national standardized board of trustee, the new " drinking water sanitary standard " that Ministry of Construction and Ministry of Public Health,etc. participated in being made has already been finished proving and verifying, will issue and implement. And 21 years later the standard is revised, concentrate people's sight again to and drink the water the safe topic come up for the first time. It is reported, the detection project of the new national standard will be increased to 106 items by 35 items, identical with the international standard. It puts forward the requirement to water quality fundamentally, has confirmed that drinks the quality of water " safe " Standard. But in actual life, common people still generally have a mistaken idea about drinking water. For example, it can be safe that people think and boil the running water to drink; The safe water is equal to healthy water,etc.. Running water ��'s safe water is at present, a lot of consumers think, the running water can be drunk directly. But because the water quality of the running water of our country has not been up to the level that some running water of developed country can be drunk directly yet, it is the most basic requirement so should drink after boiling the running water at first. However, in fact, because of environmental pollution, the public drinking water security is being threatened in an all-round way. Our country is that the sewage discharge maximum in emission of sewage increases the fastest countries in the world, so cause the water pollution of the source of water to be serious day by day. The sources of water of all parts all receive the pollution at various degrees, make the quality of water give a great discount. At the safe and healthy seminar on the senior level of drinking water that was held a few days ago, the environment of Center for Disease Prevention and Control of China learnt to say in gift in researcher's Hubei Province: "90% of the water plants can only pollute physics and microbial pollution carries on purification at present in our country, unable to the chemical contamination, for example deal with pesticide, insecticide, synthetic detergent, heavy metal, various organic and inorganic compound and other harmful toxin deeply. " It is reported, Shanghai once detected organic compound of 400 multi-type in the river source of Huangpu. An investigation in Chongqing reveals, the kind of organic pollution is up to 50 multi-type, 60 multi-type respectively in the Changjiang River, good river of imperial tomb. A seminar of Fudan University finds one of 90,000 people's crowds after carrying on the 10 -year long follow-up investigation since 1991, the algae toxin of little bag which residents of this area contain while drinking the water, the possibility to bring about in cancer has improved nearly 10 times. So, seem now, it may not already be safe to only boil, boil water. Express at the news briefing that the healthy drinking water professional Professor Li Fuxing of committee of China Medical Promotion is listed on new product of once, boiling the running water and drinking does not represent safely, because water boiling can not be " killed " Heavy metal, arsenide, cyanide, inferior nitrate, organic pollution, harmful substances, such as pesticide, insecticide, synthetic detergent,etc.. The safe water ��'s healthy water, at the same time, according to the good water standard of health which World Health Organization puts forward, safe, not clean water, vary too then healthy kind water. The expert thinks, there are some wrong views now, make common people deviate from the direction of the correct drinking water. Since the running water can't be drunk directly, and the boiled water can not guarantee the security, so a lot of people choose the draught water at present. And digest introduction of Wu DongSheng, doctor of department according to BJ Union Hospital, it will be retrieved repeatedly and utilized again to hold a barrel of buckets containing water, as time goes by, it is very apt to cause the fungal infection. Some irregular products for producing producer, the hygiene state is more difficult to guarantee. Because boiled water in the drinking machine is repeated boiling, keeps warm, it is apt to cause minerals to deposit, also influence the health. Meanwhile, the purified water is too " pure " ,All minerals and microelements are strained, it may not be useful to health instead. The expert returns the introduction, an important inducement that the patient has illness coming on that a lot of intestine suffer from diarrhoea, drink the iced water unboundedly. It is general knowledge to drink the unboiled water and suffer from diarrhoea, can be to the iced water, a lot of people's understanding has mistaken ideas, many people even think that it is a very good disinfection method to ice. In fact, in 0- 4 �� iced environments, the bacterium breeds all the same, can't guarantee hygiene and health at all. By the look of medical angle, the human gastric acid is secreted relatively less in summer, drinking iced water, iced beer in a large amount will further dilute the gastric acid, cause the intestinal function to be disorderly, therefore bring numerous relevant diseases. In addition, many " healthy beverages " at present on the market China contains candy, edible pigment and food additive, though it is harmful not to study and reveal it clearly yet, but it must be harmless not to show them either. So, the expert proposes, it is in growing up especially straight the child of puberty, should drink and suck the candy beverage few. And The public drinking water mistaken idea, except change from public oneself for avoiding, the country has taken a series of great measure too, promote and drink the water safe guarantee make obvious progress. It is reported, our government has already increased the investment in security project of drinking the water greatly at present, it is difficult to solve 67 million people's drinking water together in 5, unsafe population reduces from 379 million in 2000 by 312 million by the end of 2005 the national drinking water. It is estimated by 2015, our country will solve 267 million people's safe problem of drinking water, will account for and drink the water in 70% of unsafe people
