What is bromate

Introduction: in recent years, the frequent exposure of drinking water bromate content exceeding the standard has promoted bromate into the public view So what is bromate? The new national standard of mineral water has been implemented One of the important changes is the change of bromate content What is bromate? Next, let's introduce Baibai safety net in detail Bromate, as the name implies, is the salt of bromate (hbro3), such as sodium bromate, potassium bromate, etc Under normal circumstances, tap water does not contain bromate, but it will contain some bromide When ozone is used for disinfection, bromides react with ozone and form bromate after oxidation The concentration of bromate in water depends on the concentration of bromate in raw water, ozone dosage, dissolved organic carbon concentration and pH value of water According to relevant research, bromate has enough evidence of carcinogenic effect on experimental animals, but its carcinogenic effect on human is not sure Therefore, the International Center for cancer research (IARC) lists bromate as a potential carcinogen of group B2 (possibly carcinogenic to human) Bromate is difficult to dissolve in water, and easy to decompose when heated Drinking mineral water containing bromate for a long time can cause human cancer Women of childbearing age, pregnant women, people with low immune function, young children and elderly people may be particularly vulnerable to bromate, which may cause nausea, vomiting, gastrointestinal pain, anuria, diarrhea, central nervous system depression, hemolytic anemia, pulmonary edema, renal failure and deafness The above is the knowledge about bromate compiled by Xiaobian I hope it can help you who are interested Do you want to know more about bromate?
