Predicted no-effect concentration (PNEC) plays a vital role in assessing the ecotoxicological hazards in the ILs. A systematic methodological framework is presented for assessing the predicted environmental concentration (PEC) of ionic liquids. Initially, an effect level is predicted with a general quantitative structure-activity relationship (QSAR). Secondly, predicted no-effect concentration (PNEC) is calculated by using assessment factor (AF). The PEC is compared to the PNEC to characterize the risk for the freshwater aquatic organisms. If the ratio continued to exceed one, ionic liquids under investigation will need further aquatic risk assessment procedures, which involve iterative steps to refine the PEC and PNEC. © 2016 The Authors. publisher: Elsevier Ltd date: 2016 type: Conference or Workshop Item type: PeerReviewed identifier: Khan, M.I. and Zaini, D. and Shariff, A.M. and Moniruzzaman, M.
