Description of key information
Additional information
The substance has been shown to possess a 96-hour LC50 in freshwater fish ranging between 9640 and 10000 mg/L and a 24-hour LC50 in aquatic invertebrates of >10,000 mg/L. The 7-day toxicity threshold, approximately equivalent to the LC3, for algae was determined to be 1800 mg/L and the 16-hour toxicity threshold for microorganisms was determined to be 1050 mg/L. This substance is not considered to be acutely toxic to fish, or aquatic invertebrates, nor is it considered to be toxic to aquatic algae, cyanobacteria, or microorganisms.
Long-term toxicity to fish and aquatic invertebrates has been assessed using the Petrotox QSAR model (version 3.06), reporting NOELR values of >1000 mg/L and >1000 mg/L for Danio rerio and Daphnia magna, respectively, indicating no long-term aquatic toxicity.
