%X The biological toxicity of pentachlorophenol sodium (Na-PCP), a typical kind of aquatic organic pollutants, was tested with the MICROTOX system using luminescent bacteria with the influence of several factors taken into consideration. The EC50 of Na-PCP increases with the increasing of the pH and hardness of the sample. The EC50 (15min) of Na-PCP is approximately equal to its EC50 (20min). Compared with some common organic pollutants, which exhibit little influence on the toxicity of Na-PCP when mixed, Na-PCP is more toxic. A reduction of 14% in relative luminescent rate was observed in the experiment with a natural sample. The natural sample exhibits similar influence on the toxicity of Na-PCP similarly compared with unionized water.
