Additional information
Acute toxicity to fish:
The key study was conducted in year 1997 according to OECD Guideline 203 and EEC/Annex V C.1. and GLP. The acute toxicity of the test substance to the fathead minnow (Pimephales promelas) was determined in a 96-hour, static, aquatic effects limit test. Analyzed exposure concentration values were determined by gas chromatography with flame ionization detection (GC/FID). The 96-hour LC50 value for Pimephales promelas was estimated to be > 977.74 mg/L. The 96- hour No-Observed-Effect Concentration (NOEC) value for fathead minnows was determined to be 977.74 mg/L. The minnows in the diluent water controls exhibited normal behavior and appearance throughout the test.
A supporting toxicity to fish study was conducted in year 1981 according to the acute toxicity method. The acute toxicity of the test substance to fish ( Leuciscus idus melanotus) was determined in a 48 -hour and 96-hour, static, aquatic effects limit test. No effects were noted, therefore, the 48 -hour and 96 -hour LC50 value for fish was determined to be >500 mg/L.
Acute toxicity to Daphnia magna:
A static acute toxicity test with Daphnia magna was performed in year 1997 according to OECD Guideline 202, EU Method C.2 and GLP.
The acute toxicity of the test substance to Daphnia magna was determined in a 48-hour, definitive, static, aquatic effects limit test. No effects were noted, therefore, the 48-hour EC50 value for Daphnia magna was determined to be >1005 mg/L. The 48-hour No-Observed-Effect Concentration (NOEC) value for Daphnia magna was determined to be 1005 mg/L.
Acute toxicity to Algae:
A static acute toxicity test with unicellular green alga Selenastrum capriconutum was performed in year 2003 according to OECD Guideline 201 and GLP. No microscopic abnormalities of the cells were detected. The 72-hour EbC50 (0-72 hr) value for Selenastrum capricornutum was estimated to be >122.7 mg A.I./L. The ErC50 (0-72 hr) value was estimated to be >122.7 mg A.I./L. The 72-hour NOEC value was estimated to be 122.7 mg A.I./L.
Toxicity to microorganisms:
A static acute toxicity test with activated sludge was performed in year 2012 according to OECD Guideline 209, EU Method C.11 and EPA OPPTS 850.6800 and GLP. Under the conditions of the performed Test, the EC10 and EC50 values of test item was determined as higher than 1000 mg/L. Based on the statistical evaluation in this test the NOEC was ≥1000 mg/L.
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).
