Re: bromide in seawater and fish
Seawater contains bromide at around 65 mg/l, and bromine is obtained
commercially from seawater or natural brines by treating them with chlorine.
I haven't tried to check in chemistry books, but I would expect ozone too
would be able to oxidise bromide to bromine. A surf of the Internet revealed
some data showing bromide is present in fish at around 5 mg/kg. Again either
chlorine or ozone would oxidise this to bromine. I recollect a chemical-like
taint in semi-preserved herring products being traced to bromophenols and it
was thought that these arose from bromine liberated by chlorine acting on
phenols which, in turn, were contaminants in the fish. Unfortunately I can
not trace the reference to event at the moment.
