Description of key information

The 96-h LC50 of 0.97 mg/L in Oryzias latipes is used in the assessment.

Key value for chemical safety assessment

LC50 for freshwater fish:
0.97 mg/L

Additional information

Two studies are available for the short-term toxicity of delta-damascone to fish. One study is a semi-static GLP-compliant OECD Guideline 203 study with medaka (Oryzias latipes) (Kurume Laboratory, 2009). The concentrations were analytically verified, the 96-h LC50 was 0.97 mg/L based on measured concentrations. The other study is also a semi-static GLP-compliant OECD Guideline 203 study with the same species. The 96-h LC50 was 0.977 mg/L based on nominal concentrations (Kurume Laboratory, 2007b). The most critical value is used in the assessment, which is the 96-h LC50 of 0.97 mg/L.
