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.

Acutely harmful to aquatic invertebrates.

Key value for chemical safety assessment

Additional information

Data on short-term toxicity to aquatic invertebrates are available in the WHO Concise International Chemical Assessment Document 20 (CICAD) on Mononitrophenols (2000), the BUA report 75 for 2- and 4-nitrophenol (1992; update supplementary report 2003) and the ECB IUCLID (2000) for 2-nitrophenol. The EC50 after 48h in a guideline study according to DIN 38 412/11 with Daphnia magna was 17 mg/L. EC50 values of short-term toxicity tests with Daphnia magna and different guidelines after 24 h range between 25 and 210 mg/L.

Additionally, own data are available (BASF 1983 a-e). The EC50 values after 24 h for Daphnia magna range from 32.63 to 45.87 mg/L. Hence, 2-nitrophenol is regarded as acutely harmful to aquatic invertebrates.
