Data were randomly split into a training set of 584 compounds (75) and a test set of 195 compounds (25), preserving the proportion between the classes. Two QSAR classification trees were developed using CART (Classification and Regression Trees) machine learning technique coupled with Genetic Algorithms. The file contains the selected Dragon descriptors (9) along with CAS, SMILES, experimental BCF, experimental\/predicted KOW and mechanistic class (1, 2, 3). Further details on model development and performance along with descriptor definitions and interpretation are provided in the original manuscript (Grisoni et al., 2016).\nAttribute Information:\n3 Compound identifiers:\n\nCAS number\nMolecular SMILES\nTrain\/test splitting\n\n9 molecular descriptors (independent variables)\n\nnHM\npiPC09\nPCD\nX2Av\nMLOGP\nON1V\nN-072\nB02[C-N]\nF04[C-O]\n\n2 experimental responses:\n\nBioconcentration Factor (BCF) in log units (regression)\nBioaccumulation class (three classes)\n\nRelevant Papers:\nF.
