Description of key information
The NOEC (based on survival) for Dowfax 2A1 was determined to be 0.65 mg/L in a 7- day chronic toxicity study with Ceriodaphnia dubia, in which both survival and reproduction were assessed.

Additional information
One chronic toxicity study with invertebrates was available for Dowfax 2A1. This study measured both survival and reproduction in Ceriodaphnia dubia exposed to Dowfax 2EP (a.k.a Dowfax 2A1) over a period of 7 days. This study was deemed reliable for use and was assigned a Klimish score of 2. In this chronic study with C. dubia, the 216-hour NOEC and LC50 values (based on survival) were 0.65 mg/L and 3.97 mg/L (95% CI = 3.0 – 5.4 mg/L), respectively. The 168-hour NOEC and EC50 values (based on number of progeny) were 1.08 and 3.4 mg/L (95% CI = 0 – 8.7), respectively. The lowest NOEC value of 0.65 mg/L (based on survival) was selected as the key endpoint.
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).
