Additional information

Sodium 3(2H-benzotriazol-2-yl)-5-sec-butyl-4-hydroxybenzenesulfonate was tested in an acute toxicity test with Zebrafish (Brachidanio rerio) under semi-static conditions according to OECD guideline 203 and EEC directive C.1.

Groups of ten fish were exposed to test item at nominal concentration of 100, 178, 316, 562 and 1000 mg/L. A control was carried out with water (blank control). The LC50 after 96 h was 420 mg/L. The LC0 and LC100 after 96 h were 316 mg/L and 562 mg/L.
