Six phenolic derivatives (methyl phenol, 2-nitrophenol, 4-nitrophenol, 2-chlorophenol, 2,4-dichloro-phenol, phenol) and six heavy metals (Cu, Ni, Hg, Cd, Cr, Hg) were selected to investigate the joint toxicity of them, as well as their mixtures to Vibrio qinghaiensis sp.-Q67. The joint toxicity of twelve uniform design concentration ratio (UDCR) mixtures could be overestimated by the dose addition or by the independent action model within 95 % confidence intervals. All dose-response relationships could be effectively described by the twoparameters i.e., Weibull or Logit function with correlation coefficient (R) greater than 0.99. Results indicate that when the total effects of mixtures were below 30 %, the mixture toxicity interactions were antagonistic actions, except for one uniform design ray of Mix-U1. With the increasing of the concentration, the effect of toxicity become opposite, for the mixtures are not in the same toxicity system. Value of β is large interval in the 3.90-10.98 range.
