Additional information
Key study: A fish acute toxicity test was perforrmed by the Japanese Ministry of the Environment according to OECD TG 203. The 96h-LC50 for benzophenone in fish (Oryzias lapides) was determined to be >10 mg/L.
Key study: An acute toxicity test on Fathead Minnows (Pimephales promelas) was performed by Brooke et al. (1984) in accordance with an equivalent method to OECD Guideline 203. The 96-LC50 (based on mortality) and 96h-EC50 (based on behaviour) in Fathead Minnows for test item were determined to be 15.3 mg/L.
Key study: A second acute toxicity test on Fathead Minnows was performed by Brook et al. (1984) with a test method equivalent to OECD 203. The 96-LC50 (based on mortality) and 96h-EC50 (based on behaviour) in Fathead Minnows were determined to be 14.2 mg/L.
Supporting study: A 96h-LC50 was determined for benzophenone within a 7 -day early stage toxicity test performed in Pimephales promelas larvae (<24h old). Based on the obtained results, the 96h-LC50 was determined to be 10.89 mg/L.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
