Though known as the â??green alternatives,â?? concerns about the effects of ILs in the environment are rising such that ILs can stabilize in water systems. Furthermore, there are insufficient data on the toxicity of ILs, limiting the use of ILs for industrial applications. Ridge, LASSO, decision tree, random forest, extra tree, gradient boost, and support vector regressions were used to develop IL toxicity predictive models. Random forest yielded the strongest predictive performance, scoring the highest R2 value of 0.86, with mean absolute error and root mean square error values of 0.32 and 0.43, respectively. Feature selections were conducted to investigate the contributions of the five molecular descriptors involved in developing regression models in this work. Descriptor MSDC was found to contribute the highest at 67 in predicting the toxicity of ILs, followed by SNarA and MAXDPC, demonstrating contributions of 15.2 and 14.1, respectively. Further quantitative structureâ??activity relationship model validations were executed; the use of three descriptors resulted in a 2 increase in predictive performance for decision tree regression, whereas R2 values remained the same for random forest, extra tree, and gradient boosting. © 2024 American Institute of Chemical Engineers.
