Additional information

The substance was tested for short-term toxicity in aquatic invertebrates (Daphnia magna), algal growth inhibition (Desmodesmus subspicatus) and an activated sludge respiration inhibition.  In addition, short-term toxicity testing in fish (Brachydanio rerio) was conducted on a supporting substance (N;N;N';N'';N''-Pentamethyldipropylentriamin), based on read-across from a supporting study (structural analogue or surrogate).

The lowest aquatic L(E)C50was observed in Daphnia magna (EC50= 48 mg/L). Long-term testing in fish and invertebrates was not conducted; the substance is not poorly soluble in water, and the results of the chemical safety assessment showed that the risk characterization ratios for surface water are all below one.  Therefore, long-term aquatic toxicity testing was not indicated.
