reference toxicity test

https://doi.org/10.1351/goldbook.14984
Test conducted in conjunction with sediment tests to determine possible changes in condition of the test species.
Notes:
  1. Deviations from an established normal range indicate a change in the condition of the test organism population. Reference toxicant tests are most often acute lethality tests performed in the absence of sediment.
  2. Sediment spiked with a toxicant might also be included as a positive control for the sediment toxicity test.
