Additional information
Environmental fate and pathways :
The registered substance is hydrolytically stable at pH 4, 7 and 9 (t½ > 1 year at 25 °C) but is readily biodegradable. Therefore, the substance is not expected to persist in the environment. In addition, based on the estimated BCF at 81.5 L/kg, the substance is not considered bioaccumulable. Finally, with a Koc value at 569, the substance is low mobile in soils, according to P.J. McCall et al., 1981.
Aquatic toxicity:
Three acute experimental studies are available to assess the aquatic toxicity of the registered substance, on aquatic inverbrates, fish and algae.
The 96 hr LC50 on Oncorhynchus mykiss according to OECD 203, was determined to be 4.2 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).
The 48 hr EC50 on Daphnia magna according to OECD 202 was determined to be 13 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).
The 72 hr EC50 on aquatic algae according to OECD 201 based on growth rate was reported to be 10 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).The 72h EC10 based on growth rate was reported to be 5.2 mg/L (based on nominal concentrations, measured concentrations were >80% to nominal).
Two QSAR are available to assess the chronic aquatic toxicity of the registered substance on fish and on aquatic invertebrate
The fish 32/33d-NOEC was predicted to be 0.426 mg/L.
The daphnia 21-d NOEC was predicted to be 0.350 mg/L.
The substance was not acutely toxic to microorganisms when tested according to OECD 209. The 3 hr EC50 for activated sludge respiration inhibition was reported to be 190 mg/L (nominal).
Conclusion on classification
Data available :
- Readily biodegradable;
- Average BCF value of 81.5 and log Kow < 4
- Chronic data: Chronic effects were predicted at 0.35 mg/L for daphnids
The substance does not meet the criteria for classification as given in Commission Regulation (EU) No 286/2011 amending for the second time Regulation (EC) No 1272/2008. The substance is not classified for environmental hazards on the basis of the available 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).
