Any other information on results incl. tables

EC50 Alga (72h) of 1,6-Hexandioldimethacrylate (5.33 mg/L) is predicted from category members using trend analysis based on 17 values within the range 0.0169 - 1.03E+03 mg/L from 17 category members. Category members are single chemicals and are selected based on the profile of the target chemical. Only chemicals having experimental data are listed in the category.

The target chemical FALLS within applicability domain of the prediction. The data used for calculating the current prediction is taken from 30 experimental values selected from the following database(s): ECHA CHEM
