Additional information
For the component CAS 108 -78 -1(melamine):
The key study (Frazier 1988) is the newer of both available studies, following the EPA guideline and GLP, and was therefore selected as key. The results of the other study (Adema 1978) were consistent with those of Frazier 1988.
The 24 h and 48 h LC 50 values were both estimated to be > 1000 mg/L. The 24 and 48 hour EC 50 values were 400 and 200 mg/L respectively. The study from Lightner did not reveal effects relevant for the hazard assessment.
For the component CAS 108 -80 -5 (cyanuric acid):
Two different species have been tested. 48h LC50 (Daphnia magna) >1000 mg (LeBlanc 1978) and 96h LC50 (Mysidopsis bahia) >4000 mg/L (Anderson 2002)
