Description of key information

Short-term toxicity testing to fish was conducted with Poecilia reticulata under GLP according to OECD guideline 203. This study is supported by a non-GLP study according to DIN 38412 in Golden Orfe.

Key value for chemical safety assessment

LC50 for freshwater fish:
841 mg/L

Additional information

In the key study - GLP guideline study (Klimisch 1) - fish were observed for mortality and clinical signs at 3, 24, 48, 72, and 96 hours. At the end of the 96-hour test period, the LC50, EC50 and NOEC (no observed effect concentration) were determined for each time point. The LC50 after 96 hours of exposure was 841 mg/L These results indicate that DPnB is not acutely toxic to freshwater fish.
