The General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) announced recently that the draft revised national standard for “drinking natural mineral water†has been submitted for comments on the Internet. The initial limit for bromate in the new standard is 0.01 mg/L.
According to experts, bromate is not normally found in water, but bromide is generally present. When water is sterilized with ozone, bromide reacts with ozone to generate bromate. The International Cancer Research Center believes that potassium bromate has a carcinogenic effect on experimental animals, but the carcinogenic effect of bromate on humans is not yet certain, and this is classified as a substance that may cause cancer in humans.
In 1993, the World Health Organization set the limit of bromate in water to 0.025 mg/L in the Guidelines for Drinking-water Quality, and it was revised to 0.01 mg/L in 2004. China's current "Sanitation Standards for Drinking Water" also stipulates that the limit of bromate is 0.01mg/L.
The General Administration of Quality Supervision, Inspection and Quarantine asserts that the limits of bromate in mineral waters are not regulated by the Codex Alimentarius Commission. Some other countries have provisions, some do not, and regulations are not consistent. For example, the European Union has set a limit of 0.003 mg/L. , the United States is set to 0.01mg/L. Since early China rarely used ozone to sterilize water, the National Standard for Drinking Natural Mineral Water did not establish bromate limit requirements. In recent years, mineral water companies generally adopt ozone sterilization process, resulting in the prominent phenomenon of bromate.
The General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) also stated that the General Administration of Customs has carried out special spot checks on bromate in bottled water. 13 bromate content in 104 types of bottled water tested has exceeded 0.01 mg/L. All geological inspection departments informed these products The production company immediately rectified. At present, the General Administration of China is organizing nationwide special inspections to require all production companies to strengthen process control and ensure that the bromate content of mineral water meets drinking water standards.
