Prediction of LD50 for o,o-diethyl chlorothiophosphate, IMP 3 for Rat TrendAnalysis
Summary
Toxicity of the target chemical (2.25E+03 mg/kg) is predicted from category members using trend analysisbased on 7 values within the range 2.00E+03 - 2.00E+03 mg/kg from 7 category members. Categorymembers are single chemicals or mixtures and are selected based on the profile of the target chemical. Onlychemicals having experimental data are listed in the category.
The target chemical FALLS within applicability domain of the prediction (see Section 4.3 for details).
The descriptor values for the target chemical and the category members in case they are set oftautomers, set of metabolites or mixtures are calculated using the following rule(s):
1. "log Kow" - taking the weighted average value
The endpoint data used in the prediction is selected from the following database(s):
1. Toxicity Japan MHLW
Below is a summary table for endpoint & descriptor values for the target chemical and the categorymembers. Experimental values from data matrix are presented in bold font. Recalculated endpoint values (ifrequired by selected data usage option in Gap Filling) are presented in italic font. Recalculated endpointvalues based on experimental data only are presented in bold and italic font.
