Bromine Toxicological Overview

Bromine reacts with water resulting in the formation of hydrobromous acid, which slowly decomposes to hydrogen bromide and O2 [7]. The mechanism of action of bromine is by liberation of nascent oxygen or oxygen free radicals from the water present in mucous membranes. It is the nascent oxygen, a potent oxidiser, which is responsible for bromine-
