From: Comparative toxicity of five dispersants to coral larvae

Concentration response curves for inhibition of metamorphosis of A. millepora larvae by dispersants measured following 2, 6 and 24 h exposures. Bars represent SD ± n = 6. Shaded areas represent the 95% confidence boundaries of each 4 parameter sigmoidal model. All effect concentrations (EC10 and EC50) for each dispersant at each time point are provided in Table 3.
