The rTK models with literature-derived parameter values. a The predicted log₁₀ BCF values estimated by the 1C model from the log₁₀K_ow values for each of the chemicals in the training (black dots) and validation (red dots) sets vs. the observed log₁₀ BCF values using literature-derived parameter values. The grey line represents the line of equality (y=x). RMSE = 0.894 and 0.924 for the training and validation sets. b The predicted log₁₀ BCF values estimated by the 7C model from the log₁₀K_ow values for each of the chemicals in the training and validation sets vs. the observed log₁₀ BCF values using literature-derived parameter values. RMSE = 2.331 and 2.360 for the training and validation sets
