In seawater, chlorine levels decline <br /> rapidly; however, hypobromite (which is acutely toxic to aquatic organisms) <br /> is formed. EPA believes that the risk of acute exposure to aquatic <br /> organisms is sufficiently mitigated by precautionary labeling and National <br /> Pollutant Discharge Elimination System NPDESpermit requirements. <br /> 12.4 Bioconcentration: This material is not expected to bioconcentrate in organisms. <br /> 12.5 Biodegradation: This material is inorganic and not subject to biodegradation. <br /> Revision Date:01/01/2016 (supersedes previous revisions) Page 7 of 10 <br />
