Prediction of Cd and Pb toxicity to Vibrio fischeri using biotic ligand-based models in soil

► Biotic ligand-based models to predict Cd and Pb toxicity in soil were developed. ► Model parameters were determined by Vibrio fischeri aqueous phase toxicity tests. ► We found that toxicity of soil solution can be representative of toxicity of soil. ► Chemical analysis data of soil solution were only required as input data. ► The toxicity of Cd and Pb in soil can be successfully predicted by using the models.
