As everyone knows, inorganic arsenic carcinogen, excessive to take a photograph of affiliation, initiate skin, cardiovascular vessel, respiratory system and nervous system canceration, well known Arsenicum, it is one kind of arsenic compound. At present, China " drinking water sanitary standard " (2007) Stipulate arsenic content can't be higher than 0.01mg/L, identical with the drinking water standards of World Health Organization, European Union,etc.. But the total number of the colony represents quality of drinking water hygiene quality to a certain extent.
Why presents the water purifier" Arsenic exceeds standard " ? Though some brands are imputed to this " Transporting and storing the pollution of course causes" ,But industry is full of querying to this. The Ministry of Health measures a technical staff to point out, " arsenic of the water purifier exceeds standard the question may mainly lie in the filter and strain on the material of the core. "
It is reported it strains core to be key part of water purifier, according to strain core, make up structure, can divide into the intersection of RO and the intersection of reverse osmosis and water purifier and ultrafiltrate the intersection of membrane and water purifier,etc. generally.
Find in the investigation, the straining the material that the core uses of question water purifier though has nothing in common with each other, but adopt active charcoal, the intersection of PP and the intersection of cotton and these, strain material basically, add hollow fiber ultrafiltrate membrane or KDF (pure the intersection of copper and zinc alloy) in addition Compounded.
Expert and relevant insider of check organization think, in these materials, it is the active charcoal to most likely cause the ultra target of arsenic, because of the raw materials or making and may be polluted in the process of the active charcoal, and contain micro- arsenic. In addition, alloy material or origin that arsenic exceed standard in (note: Arsenic can be used for making hard alloy, can prevent taking off zinc if containing micro- arsenic in copper, KDF is the zinc alloy of pure copper) .
Carcinogen exceeds standard
Come from the water purifier and strain the core
Carcinogenic " black core "
Use in the water purifier in a large amount
It is reported, the idea of water purification is proposed by U.S.A. first, water purifier most advanced technology and the finest making craft are in U.S.A..
However, we find in the investigation, the testing result this time is by no means fortuitous. As the key part of the water purifier, the active charcoal strains the core qualification rate generally on the low side. Before this, the expert has pointed out the environment of Center for Disease Prevention and Control of China, the basis should measure the materials to reveal to hygiene of different kinds of home water purifiers from 2006 to 2009, the disqualification rate that the active charcoal strains the core is relatively high, its reason includes the total solid of solubility, fluoride, turbid degree, aluminium, arsenic index soaking experiment are not up to standard,etc.. It is exactly that these are carcinogenic " Black core " Use,it is not up to standard last seed of trouble water purifier.
Know the water purifier correctly
All the time, it is queried that some experts have existed to the security of the water purifier. "The water purifier adopts simple physics to filter the method, remove carcinogen and antibiotic,etc. medicine remaining and poisonous heavy metal ion such as chlorine, chloroform in water at all. Drink for a long time, use your health as the filter of water in other words, the noxious substance will be deposited in the body, influence the health seriously. " Famous nutritionist, drinking water expert Professor Li Fuxing in our country points out, there are two kinds of most basic standards on the pollution-free basis in the really healthy water: First, slightly alkaline in nature, second, contain many kinds of minerals and microelements in water. The water purifier in the course of filtering the purified water, though has filtered some suspended substance, but filter a large number of human body essential minerals and microelements in water at the same time. Moreover, this kind of purification and filtering, it will be originally neutral water or slightly alkaline water, have turned into acid water, is similar to pH value of the purified water. It diminishes the health to drink the acid water for a long time, this has already been verified for numerous experts, become the common understanding in the industry.
The truth of the water purifier is investigated
Investigate one:
Have not marked and produced and produced a large number of subquality products
According to figure that the Chinese Consumers' Association announces, at present, there are more than 3200 manufacturing enterprises of domestic water purifiers, but the great majority are not professional designed, have not obtained the small workshop that the hygiene permitted the official written reply. Meanwhile, the intersection of water purifier and product set up intact sector standard system so far, do not have clear appraisal system to the quality, function and security of the active charcoal, cause whom domestic the intersection of water purifier and trade become fish and dragons mix up together " The severely afflicated area " .
Private economic the intersection of research association and the intersection of water purification and the intersection of trade and committee's general secretary, country of China, point out, the most popular material is the active charcoal in the water purifier, including coconut palm shell charcoal, shell charcoal have low priced charcoal of nature of coal etc., widely different because of the price, the ability power of absorption is with a wide gap, it purifies the result and decreases progressively sequentially.
And these material differences can not find out from the appearance. So, some small factories substitute the active charcoal of coconut palm shell with the active charcoal of nature of coal of low price, take and retrieve the plastics and is used in to paddle on the part one grade of plastics of food. What is more, some active charcoal factories melt down and deal with the active charcoal scrapping, pretend to be the new product to sell or mix into in the new active charcoal again, in order to reduce cost and price. As far back as 2009, several domestic famous brand water purifiers have notified by the Ministry of Health because the total number of the colony has exceeded standard.
Investigate three:
Take advantage of the scientific experiment and practise deception and have the fraud
Take the running water, mineral water and make and electrolyze water experiment, these are favorite distribution modes of trade company of a lot of water purifiers. After a lot of consumers have seen the so-called electrolytic water experiment, all feel very panic: Is the running water really so dirty?
The so-called electrolytic water experiment is: Water purifier promote personnel insert person who electrolyze into water and running water which they purified, energize after the several minutes, water color that they purify has not been changed or slightly shown yellow, but the running water emits the bubble and produces umber or grayish green wadding, make people very sick. Then promote personnel to tell consumers, see how dirty the running water is actually, how good our water purifier result is!
"This is typical borrowing the so-called scientific experiment. " According to the introduction of chemical expert: Because the running water has conductivity, after the electrolyzing device is inserted into water and energized, will electrolyze the effect. And electrolyze three price irons ion produced and hydrolyze and form brown or grayish green wadding to precipitate. The promoter exactly utilizes this principle, electrolyze iron and water the product reflected, say? Kiss on high mountain this apricot unload occupy last last gold-plating spoon high mountain s striking last to be only Pi health curtain Niu so are there s pretties after coughing to Lu after leaving
Investigate two:
It is propagated only in order to try to gain the sudden huge profits of the trade that false
Under the environment of the sector standard for a long time which is short of location, " play with the concept " Have become another haphazard elephant of the water purifier trade. I notice a lot of water purifiers show " hydrophilic membrane " in the advertisement one after another , " membrane of nanometer " , " membrane of hyperfilltration " , " purely brilliant technology " , " far infrared ore " Wait for the Hi-Tech noun. Sales forces, while introducing the products, though concepts used are different, their final purposes emphasize that can be up to various efficiency of preventing and curing diseases: Dispel the spot and improve looks, slow aging, prevent cancer, supplement the calcium, improve stomachache, prevent and treat hypertension, diabetes, gout, heart disease effectively And different products make people at a loss as to what to do even more from hundreds of yuan to price difference between as many as ten thousand yuan.
As to this, the expert seriously reminds consumers, these products concept are only the self- propagation of the trade company, consumers mustn't be misled, bought blindly by the trade company.
In fact, as far back as July 11, 2005, the national relevant department had released the announcement, had revealed " some involved the safe products (hereafter referred to as and involve in the aquatic products) of hygiene of drinking water " Produce the operating unit while involving in the aquatic products in production and sales, declare it can prepare ion water or alkaline water in the name of ' the ion water machine ' without authorization, and trumpet and have various health care functions, some have relevant departments to permit the official written reply to even annotate without authorization, cheat, lead consumers into a trap " And reaffirm " Involving in the aquatic products be unable to declare function of any health care " .
Illegal trade company dare to ingore national relevant laws and regulations, it is the sudden huge profits coming from the water purifier products that are driven. According to insider: "The water purifier that a lot of domestic enterprises produce needs moderate breeze to filter and reach the level that U.S.A.'s first grade filters, sell to the water purifier at 1500 yuan too, some enterprises can earn one a thousand two three. "
Investigate four:
Secondary pollution or dirty running water
In fact, a lot of consumers do not understand, the water purifier polluted will cause bacteria and produce the secondary pollution, its water quality purified is even not so good as the running water.
The insider introduces, the national standard which the trade company of the water purifier provides, continue to use " drinking water sanitary standard " at present, and this standard is the same as standard of measurement of running water. That is to say, weigh with this standard, citizens spend money installing water that the water purifier purified additionally at home, with the running water that has not been purified, the result measured out will be " qualified " .
In addition, have mistaken ideas in the whole trade of the water purifier, it is only to filtering the detection of water after purifying at that time, but in fact, water will remain a large number of harmful substances in the purifying device through after the purifying device, this will cause water " The secondary pollution " ,This means, after using for some time, may dirty from water that comes out of the purifying device yet more than the running water that the water pipe flow out. And at present, do not still have " secondary pollution " to the purifying device Specialization detection.
How to guarantee the security that the family drinks the water
Professor Li Fuxing, director of special committee, points out that China Medical Promotion drinks the water healthily: The pollution of the running water is a global difficult problem, a lot of countries include American-European developed country, face this predicament. And our country, because of paying little attention to the one in environment protecting mode in initial stage of industrialization, the situation of the water pollution allowed of no optimist even more. Should solve the problem that the health drink the water in the family at the present stage, preferably divide the quality and use water: Namely water which enter the human body of cooking, stewing the soup and drinking etc., use the draught mineral water; And the daily domestic water of washing the vegetables, doing washing, washing the face, having a bath etc. uses the running water. Certainly, in area and period of some running water with unstable water quality, use the water purifier, also should be all right,but should not long term administration.
As to the draught water, Professor Li Fuxing points out emphatically: All draught water mineral water, now draught the intersection of moisture and two: One kind is natural mineral water; Another kind is purified water ' Or drinking water) . The draught purified water is actually purified by the running water, water difference purified with the water purifier is not big. And the good natural mineral water generally comes from the uninhabited alpine glacier, mostly the groundwater, receive the tight protection of the rock stratum, have isolated the pollution of the earth's surface, and contain many kinds of mineral quintessence and microelement, for human body, may be called water meeting physiology's needs very much. In American-European countries, the natural mineral water is more expensive than beer, even milk. In the American-European supermarket, the mineral water is put on the shelve most inside in the supermarket (because almost all the families need natural mineral water, store purpose of this measure that let, want, buy people of mineral water, pass by all shelves, could reach the mineral water shelve after having a look around all goods, thus increase the sales opportunnity of the other goods of store. )
So, the family had better choose the draught natural mineral water while drinking the water. Choosing the place of production to be clear, production technology advancement, big brand and products of the big enterprise of the operation standardard that but had better choose natural mineral water, this point is very important.
How to distinguish the natural mineral water, Li Fuxing advises consumers to see the barrel to mark carefully: The mineral water has strict national standards. Real mineral water, will mark marking out in the barrel clearly: Natural mineral water.
Finally, Professor Li Fuxing reminds the masses of consumers: Water which people drank, 80% are entered in blood directly, water quality is determining people's physique, and is having enormous influence on people's health and life-span in all one's life. As to water drunk for a long time, people should pay close attention to and treat with caution.
