Additional information

A GLP test according to EPA OTS 797.1400 (Fish Acute Toxicity Test) has been conducted under static conditions with the marine water fish Cyprinodon variegatus (Hoechst Celanese Corp., 1996; J9602007d). After 96 hours of exposure a LC50 of 88.4 mg/L was determined, based on nominal concentrations. This data were used as key value for chemical safety assessment.

 

In addition, the toxic effect of 2'-hydroxyacetophenone (CAS 118-93-4) was studied in a GLP test according to EPA OTS 797.1400 (Fish Acute Toxicity Test) performed under static conditions with the freshwater fish Lepomis macrochirus as test species (Hoechst Celanese Corp., 1996; J9602007b). After 96 hours of exposure a LC50 of 115 mg/L was determined, based on nominal concentrations.

The substance is concluded to be acutely harmful to fish.
