The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

NOEC (33d) = 101 µg a.i./L (Pimephales promelas)

Key value for chemical safety assessment

Additional information

No information about the chronic toxicity of KDDC (CAS No. 128-03-0) to fish species is available. Therefore, conclusions concerning this endpoint had to be drawn based on toxicity data from an analogue substance. The chronic toxicity of Ziram (CAS No. 137-30-4) to Pimephales promelas was investigated by Palmer et al. (2006). This test was performed according to OECD Guideline No. 210 and EPA OPPTS 850.1400, Fish, Early-Life Stage Toxicity Test (1992, 1996), under GLP conditions. Fish embryos were exposed for 33 days to the test substance within a flow-through water regime. Hatching success was significantly reduced at the highest tested concentration (750 µg a.i./L) whereas growth of the surviving larvae at the end of the test did not differ between treatment groups and controls. Larval mortality reached 100% at concentrations of 393 and 750 µg a.i./L and was significantly reduced at the 195 µg a.i./L concentration. The NOEC was determined to be 101 µg a.i./L.
