Description of key information
Biofert Plusz proved to be of low toxicity to Desmodesmus subspicatus in a study conducted according to OECD Guideline 201 (72 h ErC50: 148 mg/L based on geometric mean measured concentrations).
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 148 mg/L
- EC10 or NOEC for freshwater algae:
- 64.3 mg/L
Additional information
The toxicity of Biofert Plusz towards the unicellular green alga Desmodesmus subspicatus was investigated in a study conducted according to OECD Guideline 201 (Alga, Growth Inhibition Test). Cultures of Desmodesmus subspicatus were exposed to 5 Biofert Plusz concentrations ranging from 339 to 3559 mg/L test material (nominal) corresponding to geometric mean measured concentrations ranging from 126 to 1579 mg/L test material. The concentration of the main component of Biofert Plusz L-Threonine was determined by HPLC/UV. Based on geometric mean measured concentrations the 72 h ErC50 and 72 h EyC50 were determined to be 528 and 254 mg/L, respectively, corresponding to 148 (ErC50) and 71.4 mg dry matter/L (EyC50).
