| Use: | Toxicity tests use specific aquatic and terrestrial organisms and/or microorganisms to
measure biological response to specific contaminants or mixtures of contaminants. See 7.1.11 for use with metals, 8.2.6 for use with radionuclides, and 9.1.6 for use with explosives. |
Description:
The toxicity test consists of luminescent microorganisms which emit light as a normal consequence of respiration and a temperature controlled luminometer which reads the bacterial light output. Chemicals or chemical mixtures which are toxic to the bacteria cause a reduction in light output proportional to the strength of the toxin. A computer is linked to the system to provide data processing and storage capabilities.
