From October 8th to November 11th 2012, Toxcontrol on-line biomonitor toxicity system located at Site 3 was used to carry out the research of automated biotoxicity monitoring in drinking water sources of Tianjin. At the same time, pH, concentration of NH3-N, CODMn and DO at Site 3 and Site 4 were monitored. Totally 210 sets of effective data were obtained from the biotoxicity monitoring system during the pilot run period. The toxicity of the samples ranged from -52% to 21%, all of which was less than 30%, and did not exceed the alarm threshold. The values of pH, concentration of NH3-N, CODMn, and DO obtained simultaneously were up to the standard III of the "Surface Water Quality Standard". Significantly negative correlations were revealed between toxicity and the concentration of NH3-N (sig.<0.05), suggesting that NH3-N with a suitable concentration might play key roles in promoting the growth or light-emitting of the bacteria.
