Fish biotransformation rate constant (or half-life) QSARs

We have developed and published databases that have subsequently been used to develop and validate QSARs for predicting fish biotransformation half-lives from chemical structure. The first fish biotransformation half-life QSAR is included in the BCFBAF module of the U. S. EPA’s EPI Suite™ software package. Full details of the methods and validation statistics of the these QSARs are available:
