Aquatox Research staff routinely conduct reference toxicant tests to assess the quality of test stocks used in the conductance of toxicity tests with chemical products and environmental samples. Each of the charts presented below reflect results with a minimum of 3 to a maximum of 20 of the most recent points generated for each test and species through the period specified beside each chart. Reference toxicant identity and chart statistics are shown to the left of each thumbnail figure.
