Propiconazole	269 (123 – 468)	330 (171–537)	1,008 (704–1689)	72.2 ± 6.1

Note:

Modelled toxicity estimates for the inhibition of coral larval metamorphosis by diazinon, fipronil, imidacloprid, chlorothalonil, propiconazole and copper to Acropora tenuis. No effect concentrations (NECs) and effect concentrations (EC₁₀ and EC₅₀) were calculated from concentration-response curves (see Fig. 2). Meta. = mean larval metamorphosis (%) of larvae in uncontaminated treatments (± SE). All concentrations are in µg L⁻¹ (95% confidence intervals).
