Description of key information
No mortality was observed in the test medium after 96 hours
The following values are expressed in terms of nominal concentration:
96 h NOEC: ≥100 mg/L
96h LOEC: > 100 mg/L
96 h LC50: > 100 mg/L
The following values are expressed in terms of analytical concentration:
96 h NOEC: ≥3.10 mg/L
96h LOEC: > 3.10 mg/L
96 h LC50: > 3.10 mg/L
Key value for chemical safety assessment
Additional information
One key study (Klimisch score=1) was identified, in which FEXO-07 were tested for short-term toxicity to fish using a method according to OECD 203, EU Method C.1 and EPA OPPTS 850.1075.
The substance was tested on Danio rerio under static condition in a limit test (at the nominal concentration of 100 mg/l, corresponding to an analytical concentration of 3.1 mg/L) for a total exposure duration of 96 h.
FEX0-07 caused 0% mortality to zebra fish at the experimental conditions detailed above.
Given the nature of limit test, the 96-hour LC50 could not be determined, but, according to the binomial theory, using 7 fish per test the absence of mortality provides at least 99% confidence that the LC50 is greater than the concentration tested (i. e., LC5o > 100 mg/L). The NOEC and the LOEC were determined directly from the raw data and are listed above.
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).
