Description of key information
The registered substance is slightly soluble in water (WS < 1 mg/l), so chronic aquatic tests were performed (OECD 211, OECD 201 and OECD 210).
According to OECD test n°211, the NOEC 21d mortality has been determined at 0.052 mg/L. Reproduction NOEC and LOEC values were equal to 0.147 mg/L and 0.511 mg/L, based on parents alive at the end of the test; Effect concentrations were expressed in initial measured concentrations.
According to OECD test n°201: ErC50 -72h = 0.11 mg/l, NOEC-72h = 0.031 mg/l ( geometric mean of measured concentrations).
According to OECD test n°210, the survival and growth NOEC 33d of Pimephales promelas has been determined at 0.67 mg/l (initial measured concentration) and at 0.081 mg/L (geometric measured concentration).
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
