Basis for endpoint values:

The following metal oxides (including SiO2, as per literature convention, albeit this is strictly speaking a metalloid oxide) were evaluated on zebrafish embryos up to concentrations of 25 ug/mL ( = 25 ppm, far lower than the model development set) and up to the timepoint of 120 hpf:

[http://delloyd.50megs.com/ppm.html

"1 ppm = 1mg/l = 1ug /ml = 1000ug/L"]

Al2O3, SiO2, ZnO 

As per Figure 5(c), Table 3 and the relevant discussion, only ZnO induced mortality which was statistically significant compared to control.

N.B. The endpoint labels differ from model development, as the total mortality up to 120 hpf, rather than the excess lethality in the period 24 hpf - 120 hpf, is considered.
