Description of key information
Additional information
Acute toxicity to fish
In a 96-hr acute toxicity study, zebrafish (Danio rerio) were exposed to the test item at nominal concentrations of 0 (control) and 100 mg/L under static conditions in accordance with the OECD 203 test guideline. The test substance had no observable acute effect on fish up to its saturation limit in test media and under test conditions.
Long-term toxicity to aquatic invertebrates
In a 21-day chronic toxicity study, Daphnia magna were exposed to the test substance at 0 (control) and 100% of a saturated solution of the test substance under flow-through conditions in accordance with the OECD 211 guideline.
The following overall effect concentrations (mg/L) are based on reproduction (living offspring per introduced female) as the primary population relevant response and were obtained based on an undiluted (100%) saturated solution: LOEC > 100% saturation, NOEC ≥ 100% saturation.
Toxicity to aquatic algae
In a 72-hour algal growth study, cultures of Pseudokirchneriella subcapitata were exposed to the test item at concentrations of 0 (control) and 100% saturated solution under static conditions in accordance with the OECD 201 guideline. After 72-h an undiluted (100%) saturated solution of the test item in test media and under test conditions had no observable inhibitory effect on Pseudokirchneriella subcapitata growth.
Toxicity to microorganisms
In a 3-hr acute toxicity study sewage sludge micro-organisms were exposed to the test item at nominal concentrations of 62.5 to 1000 mg/L in a dose response design in accordance with OECD 209. The EC10 and EC50 value based on respiration rate was > 1000 mg/L after a 3 h contact time.
Conclusion:
The test substance had no observable acute and chronic effects to aquatic organisms up to its saturation limit in test media and under test conditions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
