Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The LC50 at 24, 48, 72, 96 hours was >14.0 mg/L, the NOEC at 24, 48, 72, 96 hours was >=14.0 mg/L.
The LC50 of >100 mg/L is the matching loading rate.
Key value for chemical safety assessment
Fresh water fish
Fresh water fish
- Effect concentration:
- 100 mg/L
Additional information
The acute toxicity of Melam was assessed using Oryzias latipes during an exposure period of 96 hours under static test conditions. The nominal concentration was set at 100 mg/L, and also a control group was prepared.
The concentration of the test substance was analyzed in the test solution, the concentration at the end of exposure (after 96 hours) was within +/- 20 % of the measured initial values (0 hours). Therefore, all test results were determined based on the values measured at the start of the test.
The LC50 at 24, 48, 72, 96 hours was >14.00 mg/L, the NOEC at 24, 48, 72, 96 hours was >=14.00 mg/L. The LC50 of >100 mg/L is the matching loading rate. The LC50 is greater than the figure forced in the field "Value used for CSA" and cannot be entered as a relative result (>100 mg/L).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
