PetroTox version 4.0 User Manual

17 May 2020

PetroTox is a modelling tool implementing the Target Lipid Model (TLM) for the calculation of the aquatic toxicity of complex hydrocarbon mixtures. The model allows for the calculation of acute and chronic toxicity values for several trophic levels, as well as Predicted No-Effect Concentrations (PNEC). The previous implementation in an excel sheet has been migrated to the open source data mining platform KNIME, providing several advantages in terms of performance, transparency and potential for connecting to external tools, while offering the same options and results that the previous version. The herein text serves also as a manual for the use of the PetroTox too.
