Description of key information

96h-NOEC ≥ 1000 mg/l for Danio rerio (OECD TG 203) for EDTA-Mn(NH4)2 based on read across from a study with EDTA-MnNa2

Key value for chemical safety assessment

Additional information

The toxicity of EDTA-MnNa2 to Danio rerio was investigated in a 96 -hour limit test, performed according to OECD TG 203 and under GLP (Kean, 2009). No mortality was found at the tested concentration of 1000 mg/l EDTA-MnNa2. The 96h-NOEC was therefore 1000 mg/l and recalculated to EDTA-Mn(NH4)2 this would be almost similar (Mw ratio EDTA-Mn(NH4)2/EDTA-MnNa2 = 1.003).
