Additional information

Three references have been identified for assessing impact of N-C16-18 (even numbered)-alkyl-N-methyl, C16-18 (even numbered)-alkyl-1-amine on algae. As for invertebrates, none of them are considered as Klimish 1 due to analytical measurement failure. The one which has been retained followed the OECD 201 requirements and did not use solvent for solubilizing the test item. Being the most compliant, this test was identified as a key study.
