| Use: | Toxicity tests use specific aquatic and terrestrial organisms and/or microorganisms to
measure biological response to specific contaminants or mixes of contaminants. See 6.2.25 for use with VOCs, SVOCs, and pesticides and 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.
