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
