Additional information

A study was performed in accordance with OECD guideline 203. The 96-h acute toxicity of TaC to Danio rerio was studied under semi-static conditions. Fish were exposed to TaC at a concentration of 100 mg/L (nominal concentration). Fish were observed for mortality and signs of toxicity at 3, 6, 24, 48, 72 and 96 h. Throughout the study period no mortality and no other signs of toxicity could be recorded. Accordingly, the 96-h LC50 was > 100 mg/L (nominal concentration), and the 96-h LC0 was≥ 100 mg/L.
