Time (days) required for 48 h control and TCDD-treated P. triseriata larvae to reach metamorphosis. Control P. triseriata completed metamorphosis more rapidly than TCDD- treated animals. Eggs were originally exposed for 48 h to waterborne concentrations of TCDD as follows: low (0.3 μg/l), medium (3.0 μg/l), and high (30.0 μg/l).
