Additional information
Summary of results used:
Acute study on rainbow trout:
The 96– hour LL50was 610 mg a.i./L. The 96– hr NOELR based on mortality/immobilization was 180 mg a.i./L.
Prolonged (14 -d) study on Zebra fish
The LC50 (14 d) in Zebra fish is > 108 mg/L Loading Rate WAF
Acute study on daphnia:
The 48– hour EC50was 77 mg a.i./L. The 48– hr NOEC based on mortality/immobilization was 13 mg a.i./L.
Chronic study on daphnia:
The 21 -d EL50was 100 mg a.i./L. The 21 -d NOELR based on mortality/immobilization was 56 mg a.i./L.
Study on algae:
The EL50 and NOELR values based on cell density were > 160 and 20 mg/L nominal loading rate concentrations, respectively.
Study on earthworm
The LC50 (14 -day) is > 1000 mg/kg dry weight soil
BCF
At the low concentration level, all the bioconcentration factors during the exposure period were less than the detection limit. The bioconcentration factors during the exposure period were <191 (peak A), <102 (peak B), and <222 (peak C). Based on the results mentioned above, the bioaccumulation potential of the test substance in fish tissues is judged to be low.
Conclusion on classification
As the substance is a UVCB, the 10 day window criteria for ready biodegradation is not applicable, therefore the substance is considered to be readily biodegradable and not potentially bioaccumulative.
EC50 and NOEC values based on nominal loading rate concentrations are higher than the concentration limits specified for classification of the substance for the environment.
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.
