EC number: 258-436-4
CAS number: 53220-22-7
Short-term toxicity to fish
The LC50 (96-h) of ditetradecyl peroxydicarbonate is greater than 1000 mg/L.
Long-term toxicity to fish
The main test on the endpoint Long-term toxicity to Fish will be submitted later based on ECHA communication/decision number CCH-D-2114453333-55-01/F.
Short-term toxicity to aquatic invertebrates
In a 48-hour immobilisation test with Daphnia magna the EC50 and NOEC were determined to be > 100 mg/L and 100 mg/L, respectively.
Long-term toxicity to aquatic invertebrates
Based on a worst-case exposure far in excess of a realistically achievable environmental concentration, no effects to any of the assessed endpoints were observed, therefore, the NOEC was determined to be 120 µg/L (nominal) or 44.7 µg/L (TWA).
Toxicity to aquatic algae and cyanobacteria
In a 72-h algal growth inhibition test with Pseudokirchneriella subcapitata the EC50 and the NOEC (both based on growth rate) were determined to be > 100 mg/L and 100 mg/L, respectively.
Toxicity to microorganisms
No inhibition of the respiration rate occured at 1000 mg/L of ditetradecyl peroxydicarbonate absorbed onto silica gel. This result shows that the test item, at the obtained distribution, is not toxic for activated sludge.
