Cationic surfactants like Dimethyl alkylamines (DMAs) sorb strongly to
negatively charged surfaces like glass or biota. In order to avoid
sorption to the glass of the test vessel and on the test organism well
characterized river was used as aquatic medium to allow relable test
results. In the following the acute and chronic ecotoxictiy values in
river water are given for all DMA category members to allow a direct
comparison of the test results.
Short-term aquatic toxicity tests with natural river water for
the DMA Category
Long-term aquatic toxicity tests with natural river water for
the DMA Category
* was not tested as fish is not the most sensitive species & for animal
** see discussion in IUCLID Chapter 6.0 PNEC & Conclusion on C&L and
6.1.5 Toxicity to algae
