Inner Mongolia Jing You Desert quality water is being questioned as carcinogenic water

Inner Mongolia Jing You Desert High quality water was questioned as "carcinogenic water" expert analysis-bromate exceeded the standard mineral water most recently, the Mongjingyu Desert quality water and other 6 kinds of drinking water was detected with high concentrations of carcinogens "bromate."　　The company said that because the water wells collapsed, increased ozone concentration sterilization, the production of mineral waters in the bromine acid salt exceeded the standard. "The use of ozone sterilization, is the domestic mineral water industry, the mainstream sterilization way, can produce bromate, if the enterprise does not know how to control ozone concentration, there will be bromate exceeded the situation, which is more common in mineral water."　　"Chaoyang Hospital occupational disease and poisoning Department Feng director said that through heating or filtration, it is difficult to remove bromate." Drinking water hygiene is a matter of human security. In order to eliminate pathogenic microorganisms in drinking water, chlorine water disinfection methods have been widely used in the world in recent hundred years. The chlorine gas treatment has the advantages of large water volume, low cost and continuous disinfection.　　1974 has reported that drinking water chlorination process can produce chloroform and other harmful substances, people began to pay attention to the by-products of water disinfection. Since then, people have found that ozone as a strong oxidant, can be oxidized to decompose water in a variety of organic compounds, the rapid killing of human and animal pathogenic bacteria, viruses and protozoa and other microorganisms. But the ozone disinfection drinking water also has the flaw, the biggest problem is the easily produces the latent harmful substance bromate.　　Bromate has been designated as a potential carcinogen by the International Agency for Cancer Research (2 B-Class).　　China Standards Reference International industry standards 2004 who revised the value of Bromate limit from 25μg/l to 10μg/l in drinking water quality standards.　　The EPA drinking water standard stipulates that the maximum allowable concentration of bromate is 10μg/l.　　China's October 1, 2009 promulgated the implementation of the "Drinking Natural Mineral water" national standards stipulate that bromate content can not exceed 10μg/l. Water sterilization chlorine ozone all have short board mineral water bromine acid salt exceeding standard more see the 2006 China Centers for Disease Control and Prevention research report, 12 bottles of mineral water purchased from supermarkets were tested, and bromate detected concentrations between 0.89μg/l-48.2μg/l,　　Of these, 2 kinds of bottled mineral water contain more bromate than the 10μg/l prescribed by WHO. 2008, China's Henan Provincial Center for Disease Control and Prevention staff, from the province of 7 cities randomly purchased 40 bottles of bottled water for testing.　　of which pure water 18 bottles, mineral water 9 bottles, mineral water 6 bottles, 7 bottles of Mountain springs, and another collection of urban drinking water samples of 6.　　It was found that the content of bromate in purified water and tap water samples was all qualified, while the qualified rate of spring water, mineral water and salt water was 71.4%, 66.7% and 50% respectively.　　Recently, AQSIQ published on the official website, the bottle (bucket) bottled drinking water products quality supervision and inspection results, 18 kinds of drinking water products boarded the black list, of which 6 kinds of drinking water was detected in bromate exceeded. In fact, in 2004, The Coca-Cola CompanyMineral water brand, due to bromate exceeded in the UK was recalled.　　At present, the mineral water production industry has been aware of the existence of bromate exceeded the phenomenon.
