Additional information
Melam is of low ecotoxicity.
Conclusion on classification
Melam is of low ecotoxicity. The LC50/EC50s are above 100 mg/L for the acute exposure. The NOEC for Daphnia at long-term exposure is 2.9 mg/L. The water solubility is 24.5 mg/L; melam is not ready biodegradable, has no bioaccumulation potental and has a low logPow of <-1.0. Altogether there are no indications for a classification of melam, based on ecotoxicity and/or fate and behaviour in the environment.
Melam is not a PBT or vPvB-substance because of the low bioconcentration potential, the low partition coefficient n-octanol/water and the low ecotoxicity.
