Additional information

Constituents of Paraformaldehyde, oligomeric reaction products with 4-tert-butylphenol, m-phenylenebis(methylamine) have been assessed for their aquatic bioconcentration potential by QSAR in line with OECD principals. Two of the constituents were identified in the training set of the QSAR and the reported experimental values confirm low potential for bioconcentration. The two constituents with reported experimental values are building blocks of the third, for which no experimental value was identified. Based on the QSAR prediction validated by comparison with analogues (constituent 1 and 2) the 3rd constituent has low potential for bioconcentration with high confidence.
