It is unhealthy to drink the purified water for a long time
Brief content:It should not be only to drink the water in order to quench one's thirst, it but also offer the human body essential minerals and important route of the microelement. The proportion in water of these elements is basically the same as the composition of the human body, easy to be absorbed, is favorable to the health. The purified water does not include any mineral and microelement, mineral salt content and hardness are all bordering on zero, unfavorable to the health.
People wish eagerly " Green " Food, remove the purified water of the impurity, like a stream of spring breeze, giving to people a heart brings the all in that place " green " ,For the health, a lot of families drink the purified water, regard purified water as the daily drinking water, drink for a long time, there are advantages on earth?
At present, the purified water sweeps Chinese urbanite's family, drink at ordinary times, even cook, cook the soup and use, this kind of water becomes the article for daily use that some families can not leave at moment. At present, a lot of people comparatively pay close attention to the quality problem of the purified water, the increasingly many fact lets us have to consider, what kind of influence single for a long time to drink purified water to have to health, what kind of water is the healthy water on earth.
People wish eagerly " Green " Food, remove the purified water of the impurity, like a stream of spring breeze, giving to people a heart brings the all in that place " green " . For the health, a lot of families drink the purified water. Regard purified water as daily drinking water, drink for a long time, have the intersection of advantage and pure the intersection of water quality and quantity cause anxiety " purified water " really Non- pure, have caused the extensive concern of the society. At present though the majority is basically qualified on the purified water on the market, the market of purified water really needs " purifying " . Some purified water does not accord with the sanitary standard, even make the fake. In 1999 the department of public health of Guangdong Province announced that originally saved the sampling inspection results of 94 pieces of mineral water and purified water, the total qualification rate is 71.28%, mineral water is 80.65% among them, purified water 66.6%, and the draught purified water qualification rate is only 50%, the subject problem is that the mould of bacterium exceeds standard; In March of this year, because Chen of Guangdong drank " purified water " bought in the small store It is poisoned and lived in the hospital, this " purified water " and cause Colourless and transparent, seem to be like ordinary water, but have faint pungent flavor to smell. Checked and finds what Chen drank by the hospital " The purified water " It is industrial hydrogen peroxide solution of higher density, will cause corrosion to gullet and stomach; Last early summer, together with Beijing, Hebei, Chongqing, Qingdao, Guangdong, the intersection of Wuhan and 6 draught to drink the purified water to go on and inspect by random samples to 72 brand provinces and cities the Chinese Consumers' Association, have 20 sample reach " bottled to drink the purified water sanitary standard ", in that even basic " drinking water sanitary standard " of total number of 14 pieces of sample colony can not be reached, then still not so good as the qualified running water.
All previous to find while checking, it's time to should make a decision to control already for confused state and hygiene quality problem of market of purified water.
First, the name is multifarious misleads the public. According to expert, except running water, actually there are only two big classes to pack the drinking water, natural mineral water and industry make and fetch water, the others kid people big, mislead consumers.
Second, hygiene quality causes anxiety. Some manufacturer production processes do not accord with the national sanitary standard; Some's even minimum detection tests apparatus and filling equipment not to possess either; More one is simple and crude underground small workshops of apparatuses " Production " (used after an attribute); Even specific outside personnel rent the next house owed by a citizen, the old nylon silk socks entangling the woman on the faucet of the bathroom are " filtered " ,A barrel of barrels " The purified water " Relieve oneself continually " Deliver goods to the customers " (used after a verb to indicate the completion of an action). As for packaging, some to retrieve empty barrel, some falsely use others' trade mark, some " 3 have product " that nothing does not have ,Can't find even more on date of production and quality guarantee period.
Third, the confused unordered competition of the price. It is reported, generally speaking, it nearly takes 4 tons of running water to produce a ton of purified water, in addition, pack, give water expenses etc., every barrel among 12- 15 yuan comparatively reasonable, 6, 7 one barrel those give drinking machine, it is doubtful. Have one produced in Zhejiang light bottled purified water at the market recently, each of wholesale price more than 4 mao, and generally speaking each bottle of cost should be about 7 maos. Not having good goods cheap, the persons who drink will think thrice before acting. In addition, besides quality of water, the drinking machine has many problems too. Thousands of yuan for some drinking machines on the market, some have only more than 200 yuan. These low priced drinking machines adopted materials such as the ordinary industrial plastics,etc. to produce originally, and juggled things with internal components and parts, adulterate, change the function, not only the fault rate is high, service life is short, will also cause bacterium's reproduction, enable " purified water " Secondary pollution. In recent years, the use containing purified water of barrel is more and more extensive, but a lot of persons may not know, this kind of purified water should say while drinking too " The hygiene " Question. It is heavy because of the draught water capacity, drink one generally in above, apt to receive the pollution of the microorganism in the air one week in Kaifeng, influence the water quality of drinking the water. The investigation of Center for Disease Prevention and Control, Jinan finds, the average time using a barrel of water in the office is one week, the time of the family is on above 10 days, the 5th day after the draught purified water opens sealing to use, all bacterium's total number of water samples begins to exceed standard. The prescription manager says while interviewing by reporter that the group Jinan of Wahaha handles affairs, there is a lot of more inferior purified water that appears on the market now, make the regular producer receive some influence, Wahaha group hopes ordinary people remove the scales from eyes, chooses the credible brand.
Only should not drink the water the early purified water is not the ordinary people's drinking water in order to quench one's thirst, but the supplies under a kind of particular situation. In 1950, the American scientist observed the gull in the sea, the sea water that can drink the salt of high density survived. By the finding, there is very thin membrane of one layer in gull's body, drinking the something small and hard of moisture of sea water entered can have permeated the membrane, turn the sea water into fresh water, salt, impurity in the sea water,etc. can't spit out outside the mouth through membrane. Because contrary to direction permeated naturally, so call reverse osmosis. According to this principle, the membrane of reverse osmosis of 1953 is developed successfully, the purified water was thereupon appearance too. It means through the distillation, goes to the bottled water produced out in ionizing, reverse osmosis or other appropriate course, used in Aero-Space astronaut to drink, transferred to later civilly. Because the purified water is convenient, hygiene, after introduced to the market by the trade company, have swept the whole world for a time, especially present China.
