Description of key information
The nominal concentrations of the test item of 1.0, 3.2, 10, 32 and 100 mg/L were tested in parallel with a control. The measured concentrations of Manganese oxalate dihydrate (based on manganese) in the test media of the test concentrations of 3.2 to 100 mg/L were between 97 and 110% of the nominal values at the start of the test and between 94 and 102% at the end of the test. Thus, the correct dosing of the test item Manganese oxalate dihydrate was confirmed.
The biological test results related to Manganese oxalate (correction factor: 1.252 and based on mean measured concentrations) were as follows:
EC50 72h (growth rate): 68.7 mg/L
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 68 mg/L
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
