Ions hypochlorite
WebAccording to the petition, “…hypochlorite salts break down rapidly in to non-toxic compounds when exposed to sunlight. In seawater, chlorine levels decline rapidly: however, hypobromite (which is acutely toxic to aquatic organisms) is formed. Due to the presence of 65 ppm of bromide ion in seawater, hypochlorite salts form hypobromite salts. http://mediatheque.accesmad.org/educmad/pluginfile.php/46766/mod_resource/content/0/Dosage%20doxydor%C3%A9duction.pdf
