Additional information
Short-term toxicity to fish
Reliable results are available from a study conducted according to guideline.
The acute toxicity of Trigonox K-95 to rainbow trout was investigated in a study conducted according to OECD Guideline 203 (Fish, Acute Toxicity Test) under semi-static conditions for 96 h. Ten fish were exposed to Trigonox K-95 at nominal concentrations of 1.5, 3, 6, 12, and 24 mg/L nominal. The concentration of acetone used to dissolve the test chemical was 0.1 mL/L. Analytical monitoring of test substance concentration was not performed. The 96 h NOEC, LC50 and LC100 were determined to be 1.5, 3.9, and 6 mg/L nominal. These findings are supported by the results obtained in a study conducted according to Mann (1975, 1976) and Deutsches Einheitsverfahren zur Wasser-, Abwasser- und Schlamm-Untersuchung L 15: Fischtest (Leuciscus idus melanotus.48 h LC50=14 mg/L nominal).Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
