29 EU Persistent, Bioaccumulative and Toxic (PBT) Compounds

[Workshop Home] [Participants] [Prework] [Summary] [Acknowledgements] [PredictBT Home]

The following list of PBT compounds is divided into six subsets (A-F), with 4-5 compounds each, for use in PredictBT Workshop 4 Prework. The compounds were selected from a larger list by eliminating compounds containing metals or metalloids, very simple compounds, or compounds already found in the UM-BBD. SMILES string format is described on the SSMILES Home Page from Daylight Chemical Information Systems, Inc.
