As an example she cites brominated vegetable oil or BVO, which was commonly added as an emulsifier in soft drinks such as Fanta and Gatorade. Psychosis, schizophrenia, and other mental health consequences, as a result of bromine exposure, has been known for decades. To maintain an adequate disinfection, the amount of bromine that is added must be high. When the pH value is below 8,7, more hypobromous acid (HOBr) is formed. Inorganic bromines are found in nature, but whereas they occur naturally humans have added too much through the years. Some bromide salts, notably potassium bromide, were found to be natural sedatives, and were prescribed in the 19th Century as a remedy for epilepsy. However, they had a curious side-effect. While bromine is generally easier on bathing pets than chlorine, it still can result in the irritation of a dog's sensitive system. However, there are several factors to weigh when comparing the two. In vitro profiling of the endocrine-disrupting potency of brominated flame retardants. See more. [10] Based on this fact alone, it's shocking that any bromine exposure could be considered acceptable.

Today, bromine is extracted on an industrial scale from salt lakes that are especially rich in the element, above all the Dead Sea. The chemistry blogger Derek Lowe points out that the few people known to have suffered health problems (none of which were quite like those listed by Buzzfeed) were drinking a vast amount of BVO-containing drinks - in the order of two to four litres per day. For example, ethene reacts with bromine to form 1,2-dibromoethane: CH 2 =CH 2 + Br 2 CH 2 BrCH 2 Br. A 20,000-gallon pool used year-round will cost about $600 annually to sanitize with chlorine. Anything that touches the contaminated clothing should also be placed in the bag. Assessment of the binding of hydroxylated polybrominated diphenyl ethers to thyroid hormone transport proteins using a site-specific fluorescence probe. But they are not only poisonous to the animals that they are used against, but also to larger animals. Bromine is applied in brominated flame retardants, in medicines, in photography, in oil production, in paints and in pesticides. When chlorine is added to the pool water in a shock treatment, it quickly combines with the bacteria and kills it and is then largely burned up and eliminated by the filters. The granules or liquid can be added directly to the water without any specialized equipment, while the tablets are placed in a floating dispenser to maintain adequate levels of chlorine in the water. [11] In one specific case of bromism, a patient consumed vast amounts of soda that contained brominated vegetable oil. In the old days bromine was produced by obtaining a reaction between bromides, pyrolusite and sulphuric acid. In most cases, chlorine is still used for a disinfecting effect, but it has some disadvantages, so that bromine is now becoming increasingly popular. These are less effective than hypochlorous acid. Propene, CH 3 CH=CH 2, reacts with bromine. The main advantages of bromine flame retardants are high flame retardancy efficiency and high cost performance.
