Description of key information

The substance was not acutely toxic to Daphnia magna when tested according to OECD guideline 202 (Daphnia sp. Acute Immobilisation Test), the substance was determined to possess a 24 hour LC50 of 9714 to 10000 mg/L.

Key value for chemical safety assessment

EC50/LC50 for freshwater invertebrates:
10 000 mg/L

Additional information

Three studies addressing short-term toxicity to aquatic invertebrates are presented in the dossier. 

Short-term toxicity to aquatic invertebrates.001 – daphnia -1977 – key: Acute toxicity to Daphnia magna was assessed according to OECD guideline 202 (Daphnia sp. Acute Immobilisation Test) not according to GLP (pre-dates GLP requirements). Daphnia were exposed under static conditions to the substance for 24 hours. The 24-hour EC50 for Immobility was determined to be >10,000 mg/L.

Short-term toxicity to aquatic invertebrates.002 – daphnia – 1982: Acute toxicity to Daphnia magna was assessed not according to specific guidelines but is similar to the OECD guideline 202 (Daphnia Sp. Acute Immobilisation Test). The daphnia were exposed to the substance under static conditions for 24 hours. The 24 hour EC50 was determined to be 9714 mg/L.

Short-term toxicity to aquatic invertebrates.003 – shrimp – 1974: Acute toxicity to Crangon crangon (Shrimp) was assessed not according to specific guidelines but is similar to the OECD guideline 202 (Daphnia Sp. Acute Immobilisation Test). The animals were exposed to the substance under semi-static conditions in saltwater for 96 hours. The 96 hour LC50 was determined to be 1150 ppm.
