multiple QSAR classes may be chosen by ECOSAR. Then you will get different LC50, EC50 and ChVs (see example below) for each QSAR class. Unless you have solid evidence to choose the most representative QSAR class, the lowest estimated values shall be used for further assessment. In this exam...
In above equation, exposure refers to estimated environmental concentration (EEC).Toxicity refers to an effect level or endpoint obtained from eco-toxicity testing, such as an LC50 or NOEC. After the risk quotient(s) is calculated, it is compared to EPA'sLevel of Concern (LOC). If RQ...

Six results for the endpoint mobility that were based on lethal concentrations (LC50 values) were disregarded as lethal concentrations normally refer to mortality, not mobility. All datapoints representing EC50 values (including EL50 and IC50) for immobilization in daphnids were plotted vs. the ...
The LC50 for M. galloprovincialis was 3.667% (95% CI: 1.820–7.387%) after 96 h of exposure to A. armata exudate, no mortality occurred in the control treatments. Based on this concentration, the sublethal concentrations were determined to the following endpoints. 3.2. Sublethal Toxicity Tests...

estimate predicted environmental concentrations (PECs). It is also the minimum information you need to gather before you run EUSES. In addition, if you would like to use EUSES to calculatePNECsand risk characterization result, you should also collect various eco-tox endpoints such as LC50/EC50...
