      <text>Test conducted in conjunction with sediment tests to determine possible changes in condition of the test species.</text>
      <notes>
        <item>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.</item>
        <item>Sediment spiked with a toxicant might also be included as a positive control for the sediment toxicity test.</item>
