  • Abstract Measurement and Analysis of Bromate Ion
    ABSTRACT MEASUREMENT AND ANALYSIS OF BROMATE ION REDUCTION IN SYNTHETIC GASTRIC JUICE by Jason Dimitrius Keith Bromate ion is a possible carcinogen that is regulated by the US EPA at a Maximum Contamination Level (MCL) of 10 µg/L in drinking water. In order to propose an improved scientifically appropriate bromate ion MCL, a more rigorous scientific methodology is needed for determining low level dose health risks. The objectives of this research project were to measure bromate ion with oxidizing and/or reducing agents typically ingested in foods and drinking water. The loss of bromate ion in HCl is too slow for significant reduction in the stomach. -5 Addition of 10 M H2S, a gastric juice component, decreases the half-life from 153 to 14 minutes. The ingested reducing agents iodide ion, nitrite ion, and iron(II) decrease the lifetime of bromate ion in the stomach. Chlorine, monochloramine, and iron(III) have little actual effect on the lifetime of bromate ion. The measured rates and chemical details of the reactions are discussed.

  • Bromate in Sodium Hypochlorite--Potable Water Treatment General
    THE CHLORINE INSTITUTE, INC. Bromate in Sodium Hypochlorite--Potable Water Treatment General On December 16, 2001,Stage I of the Disinfectants / Disinfection Byproducts Rule will require potable water plants to meet a bromate M.C.L. of 10 parts per billion (ppb) in their effluents. Plants that use ozone in their treatment process will be required to test monthly for bromate. Plants that do not use ozone, but use sodium hypochlorite solutions will not need to test, they will be protected by certification to ANSI / NSF Standard # 60 and/or the AWWA Standard for Hypochlorites. Industry is working with both organizations to develop specifications that easily meet this M.C.L. The sodium hypochlorite Industry wants to provide a realistic safety margin so that testing for bromate will not be required in potable water treated with this chemical. How did Bromates Get into Sodium Hypochlorite & Can they be Removed? Bromide ions are found in the salt used to make both chlorine and sodium hydroxide, the two raw materials reacted to form sodium hypochlorite. Virtually all of the bromine in chlorine and the bromide in the sodium hydroxide quickly becomes bromate at the pH of NaOCl . The concentration of bromide varies tremendously in different salt sources. It also partitions between the two chemicals (chlorine and sodium hydroxide) differently depending on the type of electrochemical cells used in the process. Some plants can change their source of salt, while others are located near salt mines and are limited to the salt they have available. Current technology cannot easily or economically remove bromate or its precursor from either the initial salt, the two reactants or the final sodium hypochlorite solution.

  • Assessment of Combined Toxic Effects of Potassium Bromate and Sodium Nitrite in Some Key Renal Markers in Male Wistar Rats
    Combined toxic effects of potassium bromate and sodium nitrite Adewale et al. Assessment of combined toxic effects of potassium bromate and sodium nitrite in some key renal markers in male Wistar rats *Adewale O.O., Aremu K.H., Adeyemo A.T. Abstract Objective: Potential combined nephrotoxic effect following simultaneous administration of two food additives: potassium bromate (PBR) (20 mg/kg of body weight, twice weekly) and sodium nitrite (SNT) (60mg/kg of body weight as a single dose) orally was investigated. Methods: Nephrotoxicity was assessed by determining urea, creatinine and electrolyte concentrations in the serum. In addition, concentrations of nitric oxide, reduced glutathione, total thiol, malondialdehyde and activities of arginase, adenosine deaminase, catalase, superoxide dismutase, and glutathione perioxidase in the kidney were investigated. Results: The results revealed that individual exposure to PBR or SNT significantly induced nephrotoxicity and oxidative stress in rats however, this was enhanced by co-exposure as evidenced by significant alteration in these kidney markers when compared with the control. Conclusion: This study accentuates the risk of enhanced nephrotoxicity in food containing both additives. Key words: Potassium bromate, sodium nitrite, renal markers. *Corresponding Author Adewale O.O. http://orcid.org/0000-0003-0387-585X Email: [email protected].

  • Occurrence of Chlorite, Chlorate and Bromate in Disinfected Swimming Pool Water
    Polish J. of Environ. Stud. Vol. 16, No. 2 (2007), 237-241 Original Research Occurrence of Chlorite, Chlorate and Bromate in Disinfected Swimming Pool Water R. Michalski*, B. Mathews institute of environmental engineering of Polish Academy of science, 34 sklodowska-curie str., 41-819 zabrze, Poland Received: June 29, 2006 Accepted: November 10, 2006 Abstract Swimming pool water treatment in general includes flocculation, sand filtration and subsequent dis- infection. Chlorite, chlorate and bromate are disinfection by-products of swimming pool water treated by chlorine species or ozone. They are responsible for adverse effects on human health and their analyses in swimming pool water are necessary. The simply and fast suppressed ion chromatography simultaneous separation and conductivity deter- mination of chlorite, chlorate, bromate, fluoride, chloride, nitrate, bromide, phosphate and sulfate in dis- infected swimming pool water has been described. The separation was performed on an anion-exchange column with 1.0 mm na2CO3 + 3.2 mm naHco3 as eluent, and determination by suppressed conductivity detection. chlorite has been found in 5 analyzed samples, chlorate in all of them, and bromate in the 2 samples originated from ozonated swimming pool water. ions were analyzed in the wide concentrations range from 0.05 mg l-1 (bromate) up to 300 mg l-1 (chloride, sulfate). Linearity of disinfection by-products was checked up to 2.0 mg/l (chlorite), 30 mg l-1 (chlorate) and 0.5 mg l-1 (bromate) with a 50 µl injection loop (r2= 0.9966 – 0.9985), respectively. Fluoride, chloride, nitrate, bromide, phosphate, and sulfate did not interfere with target anions.

  • POTASSIUM BROMATE/IODATE in BREAD and BAKERY PRODUCTS CSE Study Results and Recommendations
    A CSE POLICY BRIEF POTASSIUM BROMATE/IODATE IN BREAD AND BAKERY PRODUCTS CSE study results and recommendations INTRODUCTION Use of chemical food additives is a common practice in packaged and processed foods. Not all of them are safe. One such additive is potassium bromate (KBrO3) which, until over two decades ago, was routinely used in most parts of the world to treat flour for bread and bakery products. KBrO3 helped give the product a high rise and uniform finish. Its use as a flour treatment agent was allowed based on the assumption that no residues of bromate would be found in the final product. But following studies demonstrating detectable residues and linking bromate to cancer, global scientific expert committees – during the 1980s and early 1990s – first suggested reducing the allowed limit of use; subsequently, it was recommended that potassium bromate should not be used as a flour treatment agent. Countries across the world started to ban it – but India did not. Use of potassium bromate continues to be allowed to treat flour in our country. In the light of this, Centre for Science and Environment (CSE) decided to check for levels of potassium bromate in breads and bakery products produced in India. Tests conducted by CSE’s Pollution Monitoring Laboratory (PML) found residues of potassium bromate/ iodate in over 84 per cent of bread and bakery samples sourced from Delhi. CSE also got few samples tested by an external third-party laboratory, which confirmed the presence of bromate residues. CSE’s consultations and discussions with industry and scientific experts indicate that potassium bromate is widely used by this sector as it gives high quality results and is permitted by the law.
