| Abstract |
The toxicity of 35 test chemicals was analyzed using two microbial bioassay systems. The commercially available Microtox Toxicity Analyzer System and the two-organism procedure of Tchan were used to determine the concentration of test chemicals resulting in a 50 percent reduction in response EC(sub 50). Both of the test employed a luminescent bacterium while the procedure of Tchan also utilized a alga. Results from the two microbial tests were compared with available data obtained with fish toxicity bioassays and with each other. As a notable exception, photosynthesis-inhibiting herbicides were detected at remarkably lower concentrations with the procedure of Tchan than any of the other bioassays. Potential applications for these tests are discussed. |
