Health and safety

The imperative objective of pool disinfection is to ensure that infections are not transmitted from one bather to another through the medium of the pool water. Chlorine and bromine are the most common and effective disinfectants. However, they combine with the ammonia based pollutants that bathers bring into the water to form disinfection byproducts (DBPs). Much work has been done to chemically identify DBP and measure their affect on bathers. Nitrogen trichloride is the most well known DBP in chlorine disinfection and is found in high concentrations in pool atmospheres. Bromine disinfection forms fewer DBPs in much lower concentrations.

Two recent studies, one in Birmingham and a much larger one in Belgium, have examined the possible link between nitrogen trichloride and asthma. It was originally thought that only temporary 'asthmatic type' symptoms were induced. However, the Belgian study seems to have identified a link between exposure to nitrogen trichloride and the permanent onset of asthma in some children.

Bromine based disinfection using Poolcure removes the risk of exposure to nitrogen trichloride.
