Maximum-tolerated concentrations of solvents and carriers in zebrafish embryos and larvae.

This table depicts the highest concentrations for each solvent and carrier, at each developmental stage tested, at which no phenotypic abnormalities could be observed. Embryos and larvae were incubated in water containing each solvent or carrier at the concentration indicated, for 24 hours beginning at the developmental stage indicated. In determining the maximum tolerated concentration (MTC) for each solvent and carrier, all embryos and larvae were allowed to develop to 9 dpf, so as to detect any deleterious effects appearing after this 24-hour exposure window; none were detected at the MTCs shown.
