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.
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
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.
