Description of key information
Additional information
Relevant data available for aquatic toxicity are listed:
1. 48-h EC50 (invertebrates) : > 100 mg/L based on analytically confirmed nominal concentrations, freshwater, OECD TG 202, 2021
2. Read-Across: source data : Reaction products of 2-hydroxyethyl methacrylate and diphosphorus pentaoxide :
72-h ErC50 (aquatic algae; growth rate): = 165 mg/L based on TWA concentrations (or > 160 mg/L nominal), 72 hour, freshwater, OECD TG 201, 2004
72 -h ErC10 (aquatic algae; growth rate): = 49 mg/L based on TWA concentrations (or 92 mg/L nominal), 72 hour, freshwater, OECD TG 201, 2004
72-h NOErC (algae; growth rate): = 39 mg/L based on TWA concentrations (or 80 mg/L nominal), 72 hour, freshwater, OECD TG 201, 2004
Therefore:
72-h ErC50 (aquatic algae; growth rate): target : > 100 mg/L (or 165 mg/L) based on TWA concentrations, 72 hour, freshwater, OECD TG 201, 2021
72-h ErC10 (algae; growth rate) : target : = 49 mg/L based on TWA concentrations, 72 hour, freshwater, OECD TG 201, 2021
72-h NOErC (algae; growth rate): target : = 39 mg/L based on TWA concentrations, 72 hour, freshwater, OECD TG 201, 2021
3. Read-Across: source data : Reaction products of 2-hydroxyethyl methacrylate and diphosphorus pentaoxide :
96-h LC50 (fish) : > 100 mg/L based on analytically confirmed nominal concentrations, OECD TG 203, 2004
Therefore:
96-h LC50 (fish) : target : > 100 mg/L based on analytically confirmed nominal concentrations, freshwater, OECD TG 203, 2021
4. ASRIT:
Total Respiration Inhibition:
3h-EC50 = > 270 mg/L (nominal), 20 °C
3h-EC10 = - mg/L (nominal), 20°C
NOEC = 270 mg/L(nominal), 20 °C, OECD TG 209, 2021
Heterotrophic Respiration Inhibition:
3h-EC50 = > 270 mg/L (nominal), 20 °C
3h-EC10 = - mg/L (nominal), 20 °C
NOEC = 270 mg/L(nominal), 20 °C, OECD TG 209, 2021
Nitrification Inhibition:
3h-EC50 = > 810 mg/L (nominal), 20 °C
3h-EC10 = - mg/L (nominal), 20 °C
NOEC = 810 mg/L(nominal), 20 °C, OECD TG 209, 2021
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
