ASTM Standard

  • ASTM Standard E1924-97(2004) Standard Guide for Conducting Toxicity Tests with Bioluminescent Dinoflagellates


  • ASTM E1924 Standard Guide for Conducting Toxicity Tests with Bioluminescent Dinoflagellates, was reviewed and approved in 1997 and, reapproved in 2004. In 2006, this technology was made commercially available under the Federal Transfer of Technology Act and has been useful in environmental assessments. The ASTM E1924 test method provides a rapid toxicity response indication by measuring the reduction in bioluminescence of the plankton. The United States Navy holds the original patents to the technology.

    This toxicity detection method uses a portable instrument to measure the light output of the organism after they have been exposed to water samples. If there are harmful contaminants, bioluminescence is reduced in a predictable and measurable relationship (as toxicity increases, light decreases). The rapid toxicity test provides results in 24 hours or less and all tested samples are compared to a control group. This method is useful in screening of water bodies for toxicity or water quality due to contaminants (organic, inorganic, and heavy metals), as well as baseline assessment applications. Regular and frequent monitoring will provide more consistent and efficient use of resources in toxicity identification projects and/or remediation plans.
