Chlorine damages cells by releasing free oxygen which combines with cell 
proteins causing them to denature. Because the hypochlorite ion forms when 
such compounds as sodium hypochlorite (NaoCl; bleach)contact the organic 
materials which make up the cell membrane, it is also likely that the 
lipoprotein structure is disrupted, causing cytoplasm leakage and killing 
the cell. I hope this helps.
