Description of key information
Acute fish toxicity:One reliable study is available for an analogue of the registered substance (Parr, 2014). In this study Rainbow trout (Oncorhynchus mykiss) were exposed to a Water Accommodated Fraction of EC 613-848-7 at a nominal loading rate of 100 mg/L under semi-static conditions for 96 hours. The LL50 (96 h) was > 100 mg/L loading rate WAF. The substance is not acutely harmful to fish.
Long-term fish toxicity:One reliable study is available for an analogue of the registered substance (Parr, 2014). In this study Rainbow trout (Oncorhynchus mykiss) were exposed to a Water Accommodated Fraction of EC 613-848-7 at nominal loading rates of 10, 32 or 100 mg/L under semi-static conditions for 21 days. The LL50 (21 d) was > 100 mg/L loading rate WAF. The No Observed Effect Loading Rate was 100 mg/L loading rate WAF. The substance is not harmful to fish after prolonged exposure.
Acute toxicity to aquatic invertebrates:One reliable study is available for an analogue of the test substance (Harris, 2013). In this study Daphnia magna were exposed to a Water Accommodated Fraction of EC 613-848-7 at a nominal loading rate of 100 mg/L under static conditions for 48 hours. The EL50 (48 h) value was > 100 mg/L loading rate WAF. The substance is not acutely harmful to aquatic invertebrates.
Long-term toxicity to aquatic invertebrates:One reliable study is available for an analogue of the test substance (Harris, 2014). In this study Daphnia magna were exposed to a Water Accommodated Fraction of EC 613-848-7 at nominal loading rate of 1.0, 3.2, 10, 32 or 100 mg/L under semi-static conditions for 21days. The EL50 (21 d, immobilization) value was > 100 mg/L loading rate WAF. The EL50 (21 d, reproduction) value was > 100 mg/L loading rate WAF. The Lowest Observed Effect Loading Rate was 32 mg/L loading rate WAF (based on production of live young per adult) and the No Observed Effect Loading Rate was 10 mg/L loading rate WAF (based on parental mortality and production of live young per adult).
Toxicity to algae:One reliable study is available for an analogue of the test substance (Vreyenhoef, 2014). In this study Pseudokirchneriella subcapitata were exposed to a Water Accommodated Fraction of EC 613-848-7 at a nominal loading rate of 100 mg/L under static conditions for 72 hours. The ErL50 (72 h) value was > 100 mg/L loading rate WAF. The NOELR was 100 mg/L loading rate WAF. The substance is not harmful to algae.
Toxicity to micro-organisms:One reliable study is available for an analogue of the test substance (Roulstone, 2013). In this study activated sewage sludge was exposed to aqueous dispersions of EC 613-848-7 at up to 1000 mg/L with the addition of synthetic sewage as a respiratory substrate for 3 hours. Based on the rate of respiration, the EC50 (3 h) was > 1000 mg/L and the NOEC (3 h) was 1000 mg/L. The substance is not harmful to microorganisms.
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.
