Additional information
Acute toxicity to fish:
The acute toxicity to fish was tested in Oncorhynchus mykiss over a 96 h period in accordance to OECD (1992) Guideline 203 and EC (1992) Guideline C1. The study was conducted under continuous flow conditions and revealed a 96 h LC50 of 0.75 mg/L and a 96 h NOEC for mortality of 0.5 mg/L. The results are based on nominal concentrations.
Acute toxicity to aquatic invertebrates:
The acute toxicity to aquatic invertebrates was tested in Daphnia magna in a 48-hour immobilisation test in accordance to EU-method C.2 and OECD guideline 202. The test under semi-static conditions revealed a 48 h EC50 value of 3.05 mg/L, and a 48 h NOEC of 1.28 mg/L. The results are based on the measured geometric mean concentrations.
Toxicity to aquatic algae:
The toxicity to algae was assessed in growth inhibition test on algae in accordance to EU-method C.3 and OECD guideline 201. The 72-h EC50 value based on growth rate was determined as 5.44 mg/L and based on yield was determined as 2.56 mg/L. The overall NOEC was determined as 1.66 mg/L. The results are based on the measured geometric mean concentrations.
Toxicity to microorganisms:
The toxicity to microorganisms was tested on sewage micro-organisms bymeasuring the respiration rate under defined conditions in accordance to OECD Guideline 209. The 3h EC50 value was calculated to be 216 mg/L (187 – 252 mg/L, 95% confidence intervals) and the 3h NOEC was assessed to be 20 mg/L. The results are based on nominal concentrations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
