Concentrations of total PAHs and dispersant with effects on survival and metamorphosis

  • a Lowest-observed-effect concentration (LOEC) and no-observed-effect concentration (NOEC) for ΣPAH were calculated from one-way ANOVA (P < 0.01). EC50 settlement in sponge larvae was calculated from four-parameter logistic models (see Fig. S1 in the supplemental material).

  • b Values represent the 95% confidence interval.

  • c NA, not available. The EC50 could not be calculated due to limited data points on the slopes of dose-response curves.

  • d Corresponding TPH concentrations can be read from Table 1.
