Bromine in human tissue

Abstract

The normal levels of bromine in human tissue are given and their use in the interpretation of levels found when over-exposure is a possibility is described. Bromine is “normally” distributed in human tissue as are essential trace elements. This allows a bromine (μg) to chlorine (mg) ratio to be established (3.2) above which bromine exposure must be considered. The bromine concentrations in sections of hair can be used to establish the time of administration even when small amounts are ingested, but owing to the long half-life (about 15 days) found in human tissue interpretation after multiple doses may be difficult.
