Implemented the new national standard of mineral water from October Control bromate content strictly
From October 1, our country " drinks the natural mineral water " the national standard will begin to implement. " new national standard " Middle maximum lying in increasing the limit to bromate a bit more only, stipulate each liter can't exceed 0.01 milligrams to drink bromate content in natural mineral water. It is reported, the new national standard is in line with international standards to the limit of bromate.
The new national standard is in line with international standards
Bromate is a kind of by-product that drinking water producers used ozone to produce in the sterilization course to the drinking water in a large amount, it is determined as potential carcinogen of 2B grade by the international cancer research institution. Before this, were once exposed to the sun bromate content in some mineral spring aquatic products too high on the market, have not listed it in the relevant standard of our country.
Safe the intersection of research institute and piece, environment of Tsing-Hua University and drinking water of engineering department good for Professor, say dawn, contain bromine ion in some mineral water, when ozone that enterprises use higher density sterilize, the two reflect that has produced bromate. Bromate belong to 2B carcinogen, carcinogenic to lack of evidence to mankind, but carcinogenic evidence sufficient to animal.
U.S.A., European Union, Japan,etc. 0.01 milligrams per liter about the intersection of bromate and standard of content in the drinking water. "Drink and is in line with international standards to the limit of bromate in the new national standard of natural mineral water, should say that very safe. Consumers can rest assured to drink in the future. " Zhang XiaoJian says. If according to containing 0.01 milligrams of bromate to calculate in per liter of mineral water, drink 2 liters of mineral water per person per day, drink for 70 years, cause probably every 100,000 people of risks of tumour and have 3.
Accuse of the cost that the content increases very small severely
Zhang XiaoJian says, most mineral water producers use ozone to sterilize at present.
"After the new national standard is implemented, will impel the mineral water producer to control bromate index more strictly. If the producer has bromate that exceeds standard problems, should improve to sterilizing the craft. The proportion that the cost increased takes in the whole production process is very small. " Zhang XiaoJian says, " the content of bromine ion is not high in some regional original water, such as Beijing. We once made testing to the running water, so long as bromine ion was lower than 0.1 milligrams per liter in water, seldom will produce the intersection of bromate and issue of exceeding standard. "
The content has already been limited in the running water
Reporter yesterday ( The 21st) See at the shelve the bottled drinking water except natural mineral water in supermarket, and purified water, drinking mineral water, the three have 3- 5 brands that can be chosen from respectively. National standard it is new to drinking on mineral waters natural,other two kinds of drinking waters bottled that consumer buys often on the market - -Purified water, drinking mineral water, have a problem which contains bromate too?
Zhang XiaoJian says, consumers are totally unnecessary to be anxious. "Though the purified water adopts ozone to sterilize the way, it itself does not include bromine ion, will not produce bromate. " He explains, " it adds minerals again on the basis of purified water to drink mineral water, and neither include bromine ion, nor have this problem. "
Fixed bromate limit of " drinking water sanitary standard " that our country revises newly in 2007 is 0.01 milligrams per liter. In this standard the drinking water means the centralized type water supply, namely running water. This means several kinds of main drinking water that citizens touched while living at ordinary times, evading bromate and exceeding standard dangerously.
Packaging must label the ground of source of water in the future
Except restrict bromate index, while cancelling the index of total number of the colony in new national standard of mineral water, have increased the excrement streptococcus, false form afterbirth fungus of copper green and produced the detection of three pathogens of angry pod membrane shuttleless loom fungus, stipulate the content is " 0" .
The new national standard still stipulates, unless examine and approve and approve of by the national related departments, otherwise can't claim that there is medical function on the label, this contributes to preventing the producer from misleading consumers. To packing the products in advance, the standard stipulates that must label the place name of source of water of natural mineral water, as content of Fluorine is greater than 1.0 milligrams per liter, should mark " include Fluorine " Words. The reporter sees in a supermarket, there is actually few mineral water of the name that mark the source of water at present, in three or four brands on the shelve, only one comes from Tianjin and winds up a mountain indicating source of water. After the new national standard is implemented, will offer for the fact that consumers will buy the mineral water and consult more. (Reporter Han XiaoNi)
