Description of key information
The environmental hazard assessment was conducted based on the available data of the registered substance.The following key information from aquatic invertebrates, fish, algae and microorganisms studies have been used to evaluate the aquatic toxicity of the target substance:
Toxicity to algae (Desmodesmus subspicatus): 72 h EC50: 13 mg/l (growth rate) (OECD 201, GLP)
Toxicity to invertebrates (Daphnia magna): 48h EC50: >100 mg/l (immobility), (OECD 202, GLP)
Toxicity to fish (Cyprinus carpio): 96h LC50 16 mg/l (mortality); (OECD 203, GLP)
Toxicity to microorganisms (toxicity results of OECD 301B) : NOEC 21 mg/l.
Fatty acids, C18 -unsatd, phosphates (PFA) is an complex UVCB substance composed mainly of alkylphosphonate, phosphorylated and non-phosphorylated fatty acids. A method was developed to determine the solubility of these major components since these components are the most soluble and interesting for the toxicity studies. Based on the study results on daphnids, fish and algae determined for the registered substance, no toxicity occurred up to the maximum test concentrations of 100 mg/l (daphnids), 16 mg/l (fish) and 13 mg/l (algae). The results were based on nominal test concentrations. No reliable long-term studies are available for aquatic invertebrates, fish and algae.
PNEC values were derived from studies conducted with the test substancein accordance with the “Guidance on information requirements and chemical safety assessment, Chapter R.10”.
Additional information
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.
