DAB and AEG are new cyanotoxins of concern for drinking water In this study we first studied the presence of the two cyanotoxins present in Taiwan’s reservoirs and in the finished water of water treatment plants Then chlorination of DAB and AEG was studied for the reaction kinetics and chlorinated intermediates Finally chlorination of a cyanobacterium M aeruginosa was studied for the release and degradation of DAB and AEG DAB and AEG were found in most of the reservoirs and finished waters The rate constants between chlorine and DAB and AEG were 8 74×104 and 2 68×104 M-1s-1 while the degradation rate constants of chlorinated DAB and AEG are 0 032 and 0 009 min-1 for autodecomposion and are 7 46 and 3 55 M-1s-1 for the reaction with chlorine According to the oxidation of cyanobacteria results AEG were found to be present in finished water
